Co-Simulation of Building Energy and Control Systems with the Building Controls Virtual Test Bed  

Science Conference Proceedings (OSTI)

This article describes the implementation of the Building Controls Virtual Test Bed (BCVTB). The BCVTB is a software environment that allows connecting different simulation programs to exchange data during the time integration, and that allows conducting hardware in the loop simulation. The software architecture is a modular design based on Ptolemy II, a software environment for design and analysis of heterogeneous systems. Ptolemy II provides a graphical model building environment, synchronizes the exchanged data and visualizes the system evolution during run-time. The BCVTB provides additions to Ptolemy II that allow the run-time coupling of different simulation programs for data exchange, including EnergyPlus, MATLAB, Simulink and the Modelica modelling and simulation environment Dymola. The additions also allow executing system commands, such as a script that executes a Radiance simulation. In this article, the software architecture is presented and the mathematical model used to implement the co-simulation is discussed. The simulation program interface that the BCVTB provides is explained. The article concludes by presenting applications in which different state of the art simulation programs are linked for run-time data exchange. This link allows the use of the simulation program that is best suited for the particular problem to model building heat transfer, HVAC system dynamics and control algorithms, and to compute a solution to the coupled problem using co-simulation.

Virtual building environments (VBE) - Applying information modeling to buildings  

SciTech Connect

A Virtual Building Environment (VBE) is a ''place'' where building industry project staffs can get help in creating Building Information Models (BIM) and in the use of virtual buildings. It consists of a group of industry software that is operated by industry experts who are also experts in the use of that software. The purpose of a VBE is to facilitate expert use of appropriate software applications in conjunction with each other to efficiently support multidisciplinary work. This paper defines BIM and virtual buildings, and describes VBE objectives, set-up and characteristics of operation. It informs about the VBE Initiative and the benefits from a couple of early VBE projects.

Toward a virtual building laboratory  

SciTech Connect

In order to achieve in a timely manner the large energy and dollar savings technically possible through improvements in building energy efficiency, it will be necessary to solve the problem of design failure risk. The most economical method of doing this would be to learn to calculate building performance with sufficient detail, accuracy and reliability to avoid design failure. Existing building simulation models (BSM) are a large step in this direction, but are still not capable of this level of modeling. Developments in computational fluid dynamics (CFD) techniques now allow one to construct a road map from present BSM's to a complete building physical model. The most useful first step is a building interior model (BIM) that would allow prediction of local conditions affecting occupant health and comfort. To provide reliable prediction a BIM must incorporate the correct physical boundary conditions on a building interior. Doing so raises a number of specific technical problems and research questions. The solution of these within a context useful for building research and design is not likely to result from other research on CFD, which is directed toward the solution of different types of problems. A six-step plan for incorporating the correct boundary conditions within the context of the model problem of a large atrium has been outlined. A promising strategy for constructing a BIM is the overset grid technique for representing a building space in a CFD calculation. This technique promises to adapt well to building design and allows a step-by-step approach. A state-of-the-art CFD computer code using this technique has been adapted to the problem and can form the departure point for this research.

Computing, Networking and Services (2010)" POSTER Preliminary Results in Virtual Testing for Smart Buildings  

E-Print Network (OSTI)

Abstract. Smart buildings promise to revolutionize the way we live. Applications ranging from climate control to fire management can have significant impact on the quality and cost of these services. However, a smart building and any technology with direct effect on the safety of its occupants must undergo extensive testing. Virtual testing by means of computer simulation can significantly reduce the cost of testing and, as a result, accelerate the development of novel applications. Unfortunately, building physically-accurate simulation codes can be labor intensive. To address this problem, we propose a framework for rapid, physicallyaccurate virtual testing of smart building systems. The proposed framework supports analytical modeling and simulation of both a discrete distributed system as well as the physical environment that hosts it.

Atkinson, Karina Garbesi, Erik Page, and Francis M. Rubinstein Series Title The Journal of the Illuminating Engineering Society of North America Volume 8 Document Number 3 Pagination 161-180 Date Published January ISBN Number 1550-2716 Keywords controls, daylighting, energy, occupancy sensors, tuning. Abstract Researchers have been quantifying energy savings from lighting controls in commercial buildings for more than 30 years. This study provides a meta-analysis of lighting energy savings identified in the literature-240 savings estimates from 88 papers and case studies, categorized into daylighting strategies, occupancy strategies, personal tuning, and institutional tuning. Beginning with an overall average of savings estimates by control strategy, successive analytical filters are added to identify potential biases introduced to the estimates by different analytical approaches. Based on this meta-analysis, the bestestimates of average lighting energy savings potential are 24 percent for occupancy, 28 percent for daylighting, 31 percent for personal tuning, 36 percent for institutional tuning, and 38 percent for multiple approaches. The results also suggest that simulations significantly overestimate (by at least 10 percent) the average savings obtainable from daylighting in actual buildings.

Real-Time Building Energy Simulation Using EnergyPlus and the Building Controls Test Bed  

SciTech Connect

Most commercial buildings do not perform as well in practice as intended by the design and their performances often deteriorate over time. Reasons include faulty construction, malfunctioning equipment, incorrectly configured control systems and inappropriate operating procedures (Haves et al., 2001, Lee et al., 2007). To address this problem, the paper presents a simulation-based whole building performance monitoring tool that allows a comparison of building actual performance and expected performance in real time. The tool continuously acquires relevant building model input variables from existing Energy Management and Control System (EMCS). It then reports expected energy consumption as simulated of EnergyPlus. The Building Control Virtual Test Bed (BCVTB) is used as the software platform to provide data linkage between the EMCS, an EnergyPlus model, and a database. This paper describes the integrated real-time simulation environment. A proof-of-concept demonstration is also presented in the paper.

Sensors and Controls Research Sensors and Controls Research The Emerging Technologies team conducts research into technologies related to building sensors and controls. They work with building systems-such as a heating, ventilation, and air conditioning (HVAC) systems-to analyze energy use and help occupants manage energy costs. Building controls have the potential to reduce building energy consumption by monitoring variables and other inputs, and then automatically responding in a predetermined fashion. Research between the Department of Energy, industry, and laboratories focuses on: Sensors Photo of a ceiling-mounted fire sprinkler. Sensors are designed to help building owners and operators better manage their energy use through automation. Sensors measure predefined variables, such as the amount of natural light coming in through an office window, and then feed this data into a building's control system. The control can then respond by adjusting the various building systems. For example, sensors may note when a person leaves a room and let controls know to turn off the lights, or can ensure that faucets only release water if someone's hand is waved.

Using Building Control System for Commissioning  

E-Print Network (OSTI)

This paper summarizes the different approaches developed during Annex 40 (research project of International Energy Agency - Energy Conservation in Buildings & Community Systems ) for carrying out commissioning activities using the control system. During our work we have found that control systems in buildings have the potential to greatly improve the commissioning process. In particular, control systems can be used to carry out automated testing on the energy systems in a building in a systematic way. Technologies for carrying out automated commissioning are still in their infancy and very few tools are available for practitioners to use. However, our work has demonstrated that tools can be built using existing infrastructure at relatively low cost. In many cases, tools are software programs that can be implemented on most microprocessor-based platforms.

Intelligent Building Control System for EPBD Certification Support  

E-Print Network (OSTI)

Building commissioning is a developing concept also in the Czech Republic. At present time only some aspects of building commissioning are implemented as a part of the facility management and energy auditing processes that are related to EPBD implementation. The project, presented in this paper, aims to find ways of energy-efficient operation of existing and designed energy- efficient buildings and is based on the fact that many buildings designed according to modern principles, in its operation does not behave as expected. The project is investigating and developing procedures to help change the current often intuitive approach to operate buildings in a systematic activity, taking into account energy conservation. Modern control systems of intelligent HVAC buildings could provide not only the information needed for the operational control of building, but also to detect faults and to evaluate the energy performance of the building. Under the IEA Annex 47 project, authors started to develop tools that support additional aspects of the commissioning process, including new control system for building energy services. The paper is focused on specification of new function of building control system, providing information for existing building EPBD certification. Results in terms of implementation of this function into existing building energy control system are discussed.

Continuous Control in Buildings with Bond Graphs  

E-Print Network (OSTI)

Global warming caused by CO2 emissions as a result of energy consumption, shows its growing effects on the average temperatures worldwide. Office buildings are responsible for a major share of the 40% of the energy consumption of the built environment. We look at a way to minimize the environmental load of office buildings and at the same moment improve indoor air quality and comfort for the occupants of offices. Therefore the end-users behavior of building occupants needs to be taken into account. New design approaches are needed to implement the behavior of occupants of buildings. Improvement of the energy consumption is made possible by agent-based systems for energy management in buildings. Human-in-the-loop Technology: a technology to implement user behavior is developed. By starting from the human perspective and use available and new technology, the outcome was focused on the ability to provide improved individual comfort for the end user. As the end-users become more important within energy infrastructure of buildings, the focus is on the occupant and therefore a bottom-up design approach has been developed. In the final article an example on the level of workplace will be presented.

REACTOR ANALYSIS AND VIRTUAL CONTROL ENVIRONMENT (RAVEN) FY12 REPORT  

Science Conference Proceedings (OSTI)

RAVEN is a complex software tool that will have tasks spanning from being the RELAP-7 user interface, to using RELAP-7 to perform Risk Informed Safety Characterization (RISMC), and to controlling RELAP-7 calculation execution. The goal of this document is to: 1. Highlight the functional requirements of the different tasks of RAVEN 2. Identify shared functions that could be aggregate in modules so to obtain a minimal software redundancy and maximize software utilization. RAVEN is in fact a software framework that will allow exploiting the following functionalities: • Derive and actuate the control logic required to: o Simulate the plant control system o Simulate the operator (procedure guided) actions o Perform Monte Carlo sampling of random distributed events o Perform event three based analysis • Provide a GUI to: o Input a plant description to RELAP-7 (component, control variable, control parameters) o Concurrent monitoring of Control Parameters o Concurrent alteration of control parameters • Provide Post Processing data mining capability based on o Dimensionality reduction o Cardinality reduction In this document it will be shown how an appropriate mathematical formulation of the control logic and probabilistic analysis leads to have most of the software infrastructure leveraged between the two main tasks. Further, this document will go through the development accomplished this year, including simulation results, and priorities for the next years development

Optimizing HVAC Control to Improve Building Comfort and Energy Performance  

E-Print Network (OSTI)

This paper demonstrates the benefits of optimal control in well-designed and operated buildings using a case study. The case study building was built in 2001. The HVAC and control systems have been installed with state-of-the-art equipment which include a terminal box temperature integrated minimum airflow reset. The building has been used and operated based on the design intents. This paper presents both the existing and the optimal control schedules, which include the VAV box operation schedule, AHUs optimal control, chiller and chilled water pump control, and boiler and hot water pump control. The measured hourly HVAC electricity consumption shows that annual savings of up to 40% can be achieved with an optimal control schedule.

Energy conservation by adaptive control for a solar heated building  

DOE Green Energy (OSTI)

Identification and optimal control techniques are combined to form an adaptive optimal control strategy which is used to minimize the auxiliary energy consumption for a solar heated building. The adaptive optimal control strategy is described and application of the adaptive optimal controller to the heating, ventilating, and air conditioning (HVAC) system in an appropriate building is modeled. The building used is the newly completed National Security and Resources Study Center (NSRSC) at the Los Alamos Scientific Laboratory (LASL). The NSRSC uses an 8000 sq. ft. solar collector to provide energy for heating and cooling the building. A cost functional to define optimal performance of the HVAC system and an identification process to produce a linearized building model are combined to yield an adaptive linear regulator solution. Although solar energy is used for both heating and cooling the NSRSC, only the results from the heating simulation are available for presentation here. Energy savings predicted by the model when compared to a conventional control system are described and an alternate system configuration is briefly discussed. Plans for actual implementation of the adaptive optimal controller are discussed.

A prediction of energy savings resulting from building infiltration control  

E-Print Network (OSTI)

This thesis provides a description of the methods of application of theoretical models of heat transfer in computer simulations, to determine the energy performance of a wall or building. The heat transfer simulations include calculation equations which account for the interaction among conduction heat transfer, solar gain, and infiltration heat transfer in building walls. This interaction effect has received only limited previous study. The goal of modeling the behavior of a building with these simulations is to determine optimum arrangements of induced (or controlled) airflow direction and magnitude in building exterior walls, where the walls can be considered porous and can act, to an extent, like a heat exchanger. Recent research toward designing walls especially suited to this application has developed porous walls which are dubbed "dynamic walls." This study attempts to determine the optimum application of dynamic walls, or walls which behave in a similar fashion, in a building in a theoretical analysis. The computer simulations which apply the calculations to model the energy use of a building have been written especially for this study. The results of the theoretical analysis made for this thesis show that significant energy savings can be realized with the use of controlled airflow through non-airtight walls in a building. Comparing the energy use of a building which uses airflow control in dynamic walls with the energy use found with a standard calculation (where the interaction effect is not considered), annual energy savings were found in a warm climate as high as 17%, and as high as 30% in a cooler climate. The results were less promising when compared against the performance of a building experiencing natural, or not induced, airflow (and heat recovery) through its exterior walls: the best annual savings percentages were 10% in a warm climate and just 2% in a cooler climate. The specific building airflow arrangements which produce the best theoretical performances found in this study should be considered for application in future experimental tests, if the dynamic walls and/or building airflow control system are considered economically feasible in light of the projected energy savings they produce.

Control and Room Temperature Optimization of Energy Efficient Buildings  

SciTech Connect

The building sector consumes a large part of the energy used in the United States and is responsible for nearly 40% of greenhouse gas emissions. It is therefore economically and environmentally important to reduce the building energy consumption to realize massive energy savings. In this paper, a method to control room temperature in buildings is proposed. The approach is based on a distributed parameter model represented by a three dimensional (3D) heat equation in a room with heater/cooler located at ceiling. The latter is resolved using finite element methods, and results in a model for room temperature with thousands of states. The latter is not amenable to control design. A reduced order model of only few states is then derived using Proper Orthogonal Decomposition (POD). A Linear Quadratic Regulator (LQR) is computed based on the reduced model, and applied to the full order model to control room temperature.

A Prediction of Energy Savings Resulting from Building Infiltration Control  

E-Print Network (OSTI)

Heat transfer through building walls consists of three main components: conduction heat transfer, solar gain and infiltration heat transfer. An interaction among these three heat transfer components alters the effective heat transfer through a wall, working to reduce or increase it. This study uses simulation to evaluate the potential energy impact of the interaction when several different strategies for controlling air leakage direction and velocity in building envelope components are implemented. The simulations performed in this study show that significant energy savings can be realized with the use of controlled airflow through non-airtight walls in a building. Comparing the energy load of a building which uses airflow control in its walls with the energy load found with a standard calculation (where the interaction effect is not considered), annual energy load savings were found in a warm climate as high as 17%. The results were less promising when compared against the performance of a building experiencing simulated natural airflow (and heat recovery) through its exterior walls: the best annual load savings percentage was 10% in a warm climate. It was found that in a cooler climate, the natural flow configuration performed about as well as any of the artificial airflow configurations, so airflow control is not recommended in cool climates.

Achieving Better Building Performance and Savings Using Optimal Control Strategies  

E-Print Network (OSTI)

The Continuous Commissioning (CCSM) process has become a very important energy conservation topic for new and existing commercial buildings. This process can yield substantial operating savings, improved indoor air quality, and enhanced occupant comfort. It also provides solutions to reoccurring building maintenance problems. One tool that can be implemented during commissioning work is a nearoptimal global set point method in an Energy Management Control System (EMCS) Direct Digital Controller (DDC). This algorithm is based on mathematical models for the chillers, boilers, chilled and hot water pumps, and air handler fans that relate the power of these components as a function of the chilled water and hot water differential temperature. The algorithm will minimize the total plant power consumption. These optimal control strategies make the CC process more effective. The Texas A&M University Systems State Headquarters is an office building, with a total floor area of approximately 123,960 ft2. An integrated commissioning of the HVAC systems was performed for this building. This paper describes the commissioning activities and demonstrates how newly developed optimized control strategies improved the building comfort conditions and reduced utility costs during and after the commissioning period.

At the Modelica 2009 conference, we introduced the Buildings library, a freely available Modelica library for building energy and control systems. This paper reports the updates of the library and presents example applications for a range of heating, ventilation and air conditioning (HVAC) systems. Over the past two years, the library has been further developed. The number of HVAC components models has been doubled and various components have been revised to increase numerical robustness.The paper starts with an overview of the library architecture and a description of the main packages. To demonstrate the features of the Buildings library, applications that include multizone airflow simulation as well as supervisory and local loop control of a variable air volume (VAV) system are briefly described. The paper closes with a discussion of the current development.

The lighting controls system specified by the Times Company for its new headquarters building is a DALI (Digital Addressable Lighting Interface) based system with dimmable fixtures throughout the interior space. This allows the system to dim down the electric lighting in response to daylight admittance. It also provides for variable target set points for illuminance levels at the work plane. The Times Company intends to establish and adjust target set points on a departmental basis. The lighting control sequences are described within the specification 16575. These sequences utilize occupancy sensors, photo sensors, switches and a time clock to control the lighting in the interior space on each floor. The emergency lighting system is also described within the specification. The lighting control sequences are tied to Control Intent Diagrams that divide up the space on each floor into its various control zones. The overall intent is to provide electric light only when the space is occupied and to provide as little electric light as is necessary to achieve the target set point for the work plane in a given department. A department usually occupies multiple floors.

Automated Demand Response Strategies and Commissioning CommercialBuilding Controls  

SciTech Connect

California electric utilities have been exploring the use of dynamic critical peak pricing (CPP) and other demand response programs to help reduce peaks in customer electric loads. CPP is a new electricity tariff design to promote demand response. This paper begins with a brief review of terminology regarding energy management and demand response, followed by a discussion of DR control strategies and a preliminary overview of a forthcoming guide on DR strategies. The final section discusses experience to date with these strategies, followed by a discussion of the peak electric demand savings from the 2005 Automated CPP program. An important concept identified in the automated DR field tests is that automated DR will be most successful if the building commissioning industry improves the operational effectiveness of building controls. Critical peak pricing and even real time pricing are important trends in electricity pricing that will require new functional tests for building commissioning.

Hybrid Model for Building Performance Diagnosis and Optimal Control  

E-Print Network (OSTI)

Modern buildings require continuous performance monitoring, automatic diagnostics and optimal supervisory control. For these applications, simplified dynamic building models are needed to predict the cooling and heating requirement viewing the building as a whole system. This paper proposes a new hybrid model. Half of the model is represented by detailed physical parameters and another half is described by identified parameters. 3R2C thermal network model, which consists of three resistances and two capacitances, is used to simulate building envelope whose parameters are determined in frequency domain using the theoretical frequency characteristics of the envelope. Internal mass is represented by a 2R2C thermal network model, which consists of three resistances and two capacitances. The resistances and capacitances of the 2R2C model are assumed to be constant. A GA (genetic algorithm)-based method is developed for model parameter identification by searching the optimal parameters of 3R2C models of envelopes in frequency domain and that of the 2R2C model of the building internal mass in time domain. As the model is based on the physical characteristics, the hybrid model can be used to predict the cooling and heating energy consumption of buildings accurately in wide range of operation conditions.

Energy-Efficient Building HVAC Control Using Hybrid System LBMPC  

E-Print Network (OSTI)

Improving the energy-efficiency of heating, ventilation, and air-conditioning (HVAC) systems has the potential to realize large economic and societal benefits. This paper concerns the system identification of a hybrid system model of a building-wide HVAC system and its subsequent control using a hybrid system formulation of learning-based model predictive control (LBMPC). Here, the learning refers to model updates to the hybrid system model that incorporate the heating effects due to occupancy, solar effects, outside air temperature (OAT), and equipment, in addition to integrator dynamics inherently present in low-level control. Though we make significant modeling simplifications, our corresponding controller that uses this model is able to experimentally achieve a large reduction in energy usage without any degradations in occupant comfort. It is in this way that we justify the modeling simplifications that we have made. We conclude by presenting results from experiments on our building HVAC testbed, which s...

CONVERGING REDUNDANT SENSOR NETWORK INFORMATION FOR IMPROVED BUILDING CONTROL  

SciTech Connect

Knowing how many people occupy a building, and where they are located, is a key component of building energy management and security. Commercial, industrial and residential buildings often incorporate systems used to determine occupancy, however, current sensor technology and control algorithms limit the effectiveness of both energy management and security systems. This topical report describes results from the first phase of a project to design, implement, validate, and prototype new technologies to monitor occupancy, control indoor environment services, and promote security in buildings. Phase I of the project focused on instrumentation and data collection. In this project phase a new occupancy detection system was developed, commissioned and installed in a sample of private offices and open-plan office workstations. Data acquisition systems were developed and deployed to collect data on space occupancy profiles. Analysis tools based on Bayesian probability theory were applied to the occupancy data generated by the sensor network. The inference of primary importance is a probability distribution over the number of occupants and their locations in a building, given past and present sensor measurements. Inferences were computed for occupancy and its temporal persistence in individual offices as well as the persistence of sensor status. The raw sensor data were also used to calibrate the sensor belief network, including the occupancy transition matrix used in the Markov model, sensor sensitivity, and sensor failure models. This study shows that the belief network framework can be applied to the analysis of data streams from sensor networks, offering significant benefits to building operation compared to current practice.

Demonstration of Smart Building Controls to Manage Building Peak Loads: Innovative Non-Wires Technologies  

SciTech Connect

As a part of the non-wires solutions effort, BPA in partnership with Pacific Northwest National Laboratory (PNNL) is exploring the use of two distributed energy resources (DER) technologies in the City of Richland. In addition to demonstrating the usefulness of the two DER technologies in providing peak demand relief, evaluation of remote direct load control (DLC) is also one of the primary objectives of this demonstration. The concept of DLC, which is used to change the energy use profile during peak hours of the day, is not new. Many utilities have had success in reducing demand at peak times to avoid building new generation. It is not the need for increased generation that is driving the use of direct load control in the Northwest, but the desire to avoid building additional transmission capacity. The peak times at issue total between 50 and 100 hours a year. A transmission solution to the problem would cost tens of millions of dollars . And since a ?non wires? solution is just as effective and yet costs much less, the capital dollars for construction can be used elsewhere on the grid where building new transmission is the only alternative. If by using DLC, the electricity use can be curtailed, shifted to lower use time periods or supplemented through local generation, the existing system can be made more reliable and cost effective.

Hierarchical fuzzy control of low-energy building systems  

Science Conference Proceedings (OSTI)

A hierarchical fuzzy supervisory controller is described that is capable of optimizing the operation of a low-energy building, which uses solar energy to heat and cool its interior spaces. The highest level fuzzy rules choose the most appropriate set of lower level rules according to the weather and occupancy information; the second level fuzzy rules determine an optimal energy profile and the overall modes of operation of the heating, ventilating and air-conditioning system (HVAC); the third level fuzzy rules select the mode of operation of specific equipment, and assign schedules to the local controllers so that the optimal energy profile can be achieved in the most efficient way. Computer simulation is used to compare the hierarchical fuzzy control scheme with a supervisory control scheme based on expert rules. The performance is evaluated by comparing the energy consumption and thermal comfort. (author)

Converging Redundant Sensor Network Information for Improved Building Control  

Science Conference Proceedings (OSTI)

This project investigated the development and application of sensor networks to enhance building energy management and security. Commercial, industrial and residential buildings often incorporate systems used to determine occupancy, but current sensor technology and control algorithms limit the effectiveness of these systems. For example, most of these systems rely on single monitoring points to detect occupancy, when more than one monitoring point could improve system performance. Phase I of the project focused on instrumentation and data collection. During the initial project phase, a new occupancy detection system was developed, commissioned and installed in a sample of private offices and open-plan office workstations. Data acquisition systems were developed and deployed to collect data on space occupancy profiles. Phase II of the project demonstrated that a network of several sensors provides a more accurate measure of occupancy than is possible using systems based on single monitoring points. This phase also established that analysis algorithms could be applied to the sensor network data stream to improve the accuracy of system performance in energy management and security applications. In Phase III of the project, the sensor network from Phase I was complemented by a control strategy developed based on the results from the first two project phases: this controller was implemented in a small sample of work areas, and applied to lighting control. Two additional technologies were developed in the course of completing the project. A prototype web-based display that portrays the current status of each detector in a sensor network monitoring building occupancy was designed and implemented. A new capability that enables occupancy sensors in a sensor network to dynamically set the 'time delay' interval based on ongoing occupant behavior in the space was also designed and implemented.

control systems control systems Overview The architectural approach The owner's approach Daylighting field study Daylighting control systems Automated roller shades Procurement specifications Shades and Shade Controls Lighting Controls Visualizing daylight Commissioning/ verification Demand response Mainstream solutions Post-occupancy evaluation Publications Sponsors Project team Daylighting control systems Lighting energy savings were greater in zones daylit bilaterally from both the southwest and northwest facades, typically 50-60% at 11 feet from the windows and 25-40% at 14-25 feet from the façade. Total illuminance was maintained in all lighting zones to within -10% of the setpoint for 95-100% of the day throughout most of the nine-month monitored period. Daylight "harvesting" strategies are implemented using daylighting control systems that dim the electric lighting in response to interior daylight levels. For commercial applications, the light output of fluorescent lamps (T5 or T8) are varied by using electronic dimming ballasts. Photosensors, typically mounted in the ceiling, are used to measure the quantity of daylight in the space then determine the amount of dimming required to maintain the design work plane illuminance level. If daylight levels are more than adequate, the electric lights can be shut off. Simulation studies indicate that annual energy use and peak demand can be reduced by 20-30% compared to a non-daylit building. These technological solutions are increasingly becoming one of the key means to achieving compliance with stringent energy-efficiency standards and achieving LEED ratings for sustainable design.

Small- and Medium-Sized Commercial Building Monitoring and Controls Needs: A Scoping Study  

SciTech Connect

Buildings consume over 40% of the total energy consumption in the U.S. A significant portion of the energy consumed in buildings is wasted because of the lack of controls or the inability to use existing building automation systems (BASs) properly. Much of the waste occurs because of our inability to manage and controls buildings efficiently. Over 90% of the buildings are either small-size (<5,000 sf) or medium-size (between 5,000 sf and 50,000 sf); these buildings currently do not use BASs to monitor and control their building systems from a central location. According to Commercial Building Energy Consumption Survey (CBECS), about 10% of the buildings in the U.S. use BASs or central controls to manage their building system operations. Buildings that use BASs are typically large (>100,000 sf). Lawrence Berkeley National Laboratory (LBNL), Oak Ridge National Laboratory (ORNL) and Pacific Northwest National Laboratory (PNNL) were asked by the U.S. Department of Energy’s (DOE’s) Building Technologies Program (BTP) to identify monitoring and control needs for small- and medium-sized commercial buildings and recommend possible solutions. This study documents the needs and solutions for small- and medium-sized buildings.

We also establish that analysis algorithms can be applied to the sensor network data stream to improve the accuracy of system performance in energy management and security applications, and show that it may be possible to use sensor network pulse rate to distinguish the number of occupants in a space. Finally, in this phase of the project we also developed a prototype web-based display that portrays the current status of each detector in a sensor network monitoring building occupancy. This basic capability will be extended in the future by applying an algorithm-based inference to the sensor network data stream, so that the web page displays the likelihood that each monitored office or area is occupied, as a supplement to the actual status of each sensor.

Advanced, Integrated Control for Building Operations to Achieve 40% Energy Saving  

SciTech Connect

we developed and demonstrated a software based integrated advanced building control platform called Smart Energy Box (SEB), which can coordinate building subsystem controls, integrate variety of energy optimization algorithms and provide proactive and collaborative energy management and control for building operations using weather and occupancy information. The integrated control system is a low cost solution and also features: Scalable component based architecture allows to build a solution for different building control system configurations with needed components; Open Architecture with a central data repository for data exchange among runtime components; Extendible to accommodate variety of communication protocols. Optimal building control for central loads, distributed loads and onsite energy resource Uses web server as a loosely coupled way to engage both building operators and building occupants in collaboration for energy conservation. Based on the open platform of SEB, we have investigated and evaluated a variety of operation and energy saving control strategies on Carnegie Mellon University Intelligent Work place which is equipped with alternative cooling/heating/ventilation/lighting methods, including radiant mullions, radiant cooling/heating ceiling panels, cool waves, dedicated ventilation unit, motorized window and blinds, and external louvers. Based on the validation results of these control strategies, they were integrated in SEB in a collaborative and dynamic way. This advanced control system was programmed and computer tested with a model of the Intelligent Workplaceâ??s northern section (IWn). The advanced control program was then installed in the IWn control system; the performance were measured and compared with that of the state of the art control system to verify the overall energy savings great than 40%. In addition advanced human machine interfaces (HMI's) were developed to communicate both with building occupants and the building operator. Lifecycle cost analyses of the advanced building control were performed, and a Building Control System Guide was prepared and published to inform owners, architects, and engineers dealing with new construction or renovation of buildings.

Reasons include faulty construction, malfunctioning equipment, incorrectly configured control systems and inappropriate operating procedures (Haves et al., 2001, Lee et al., 2007). To address this problem, the paper presents a simulation-based whole building performance monitoring tool that allows a comparison of building actual performance and expected performance in real time. The tool continuously acquires relevant building model input variables from existing Energy Management and Control System (EMCS). It then reports expected energy consumption as simulated of EnergyPlus. The Building Control Virtual Test Bed (BCVTB) is used as the software platform to provide data linkage between the EMCS, an EnergyPlus model, and a database. This paper describes the integrated real-time simulation environment. A proof-of-concept demonstration is also presented in the paper.

Demand Responsive and Energy Efficient Control Technologies andStrategies in Commercial Buildings  

SciTech Connect

Commercial buildings account for a large portion of summer peak electric demand. Research results show that there is significant potential to reduce peak demand in commercial buildings through advanced control technologies and strategies. However, a better understanding of commercial buildings contribution to peak demand and the use of energy management and control systems is required to develop this demand response resource to its full potential. The main objectives of the study were: (1) To evaluate the size of contributions of peak demand commercial buildings in the U.S.; (2) To understand how commercial building control systems support energy efficiency and DR; and (3) To disseminate the results to the building owners, facility managers and building controls industry. In order to estimate the commercial buildings contribution to peak demand, two sources of data are used: (1) Commercial Building Energy Consumption Survey (CBECS) and (2) National Energy Modeling System (NEMS). These two sources indicate that commercial buildings noncoincidental peak demand is about 330GW. The project then focused on technologies and strategies that deliver energy efficiency and also target 5-10% of this peak. Based on a building operations perspective, a demand-side management framework with three main features: (1) daily energy efficiency, (2) daily peak load management and (3) dynamic, event-driven DR are outlined. A general description of DR, its benefits, and nationwide DR potential in commercial buildings are presented. Case studies involving these technologies and strategies are described. The findings of this project are shared with building owners, building controls industry, researchers and government entities through a webcast and their input is requested. Their input is presented in the appendix section of this report.

IZ-CON: an intelligent zone controller for building systems operation  

E-Print Network (OSTI)

This paper describes the concept of an intelligent zone controller (IZ-CON) for integrated operation of building systems. IZ-CON is intended to deploy a predictive control methodology with embedded simulation capability. Thereby, the scalability problem of predictive simulation-assisted control method toward accommodating large and complex buildings is addressed. Moreover, the IZ-CON is inspired by a specific approach to building's control scheme involving the division of the target building into a number of well-formed sub-domains. Toward this end, a generative scheme for representation of buildings' systems control architecture is developed that allows for a structured distribution of systems' control logic. The scheme is cogently derived from a limited set of initial relationships between two entity layers. The first entity layer comprises of building zones subject to environmental control actions. The second layer comprises of technical devices responsible for control functionality. The entire control scheme - including the IZ-CON nodes - is derived in an automated fashion based on the relationships between the above two layers.

Effective, low-cost HVAC controls upgrade in a small bank building  

Science Conference Proceedings (OSTI)

This report summarizes the measured results from a field study of the performance of a low-cost controls retrofit in a small bank building in Knoxville, TN. The retrofit consisted of a simple upgrade of heating and cooling system controls and new operating strategies. The project was undertaken to better understand how commercial energy use measurement studies should be performed and to demonstrate the effectiveness of a low-cost controls retrofit in a small commercial building. This report describes the details of the project, including building and building system characteristics, the HVAC control changes made, energy end use patterns, and the heating and cooling energy savings achieved. An improved control strategy involving thermostat setback/setup and on/off control was devised around a single replacement programmable thermostat. The strategy allowed thermostat setback/setup control of the primary HVAC system in the building and provided on/off (time-of-day) control for the two secondary systems. The energy efficiency improvements provided a 33% reduction in heating and a 21% reduction in cooling energy consumptions. Simple payback for the retrofit, including installation cost, was under 1 year. In addition to reducing the energy needs of the building, the replacement electronic thermostat provided improved interior comfort. 9 refs., 12 figs., 3 tabs.

Predictive Optimal Control of Active and Passive Building Thermal Storage Inventory  

DOE Green Energy (OSTI)

Cooling of commercial buildings contributes significantly to the peak demand placed on an electrical utility grid. Time-of-use electricity rates encourage shifting of electrical loads to off-peak periods at night and weekends. Buildings can respond to these pricing signals by shifting cooling-related thermal loads either by precooling the building's massive structure or the use of active thermal energy storage systems such as ice storage. While these two thermal batteries have been engaged separately in the past, this project investigates the merits of harnessing both storage media concurrently in the context of predictive optimal control. This topical report describes the demonstration of the model-based predictive optimal control for active and passive building thermal storage inventory in a test facility in real-time using time-of-use differentiated electricity prices without demand charges. The laboratory testing findings presented in this topical report cover the second of three project phases. The novel supervisory controller successfully executed a three-step procedure consisting of (1) short-term weather prediction, (2) optimization of control strategy over the next planning horizon using a calibrated building model, and (3) post-processing of the optimal strategy to yield a control command for the current time step that can be executed in the test facility. The primary and secondary building mechanical systems were effectively orchestrated by the model-based predictive optimal controller in real-time while observing comfort and operational constraints. The findings reveal that when the optimal controller is given imperfect weather fore-casts and when the building model used for planning control strategies does not match the actual building perfectly, measured utility costs savings relative to conventional building operation can be substantial. This requires that the facility under control lends itself to passive storage utilization and the building model includes a realistic plant model. The savings associated with passive building thermal storage inventory proved to be small be-cause the test facility is not an ideal candidate for the investigated control technology. Moreover, the facility's central plant revealed the idiosyncratic behavior that the chiller operation in the ice-making mode was more energy efficient than in the chilled-water mode. Field experimentation (Phase III) is now required in a suitable commercial building with sufficient thermal mass, an active TES system, and a climate conducive to passive storage utilization over a longer testing period to support the laboratory findings presented in this topical report.

Design and Optimization of Control Strategies and Parameters by Building and System Simulation  

E-Print Network (OSTI)

Control parameters for HVAC systems are usually set during the Initial Commissioning Process within the Acceptance Phase of buildings. The quality of the Testing, Adjusting and Balancing (TAB) depends primarily on the specifications of the designer and on the knowledge of the constructor (commissioning personnel). Often the TAB and thus the Initial Commissioning is considered as completed after the functionality and performance of the systems are proven. Therefore, further optimization concerning the energy consumption does not take place. The building and system simulation usually is used during the pre-design of buildings to determine and optimize the influence of the building envelope relating to the energy demand for heating and cooling. Furthermore it is sometimes used for dimensioning the HVAC systems and particular components during the design phase. Additional abilities of the simulation models to predict or even control the building operations are not used. The purpose of the chosen approach is to use the dynamic building and system simulation to design and verify control strategies and determine the exact setup for the control parameters. Therefore the models from the former design phases have to be adapted and extended so that the control strategies can be considered in the right way. This paper presents an example how to use the dynamic simulation to optimize the characteristic of a heating and cooling system of a school building.

Economic analysis of the daylight-linked lighting control system in office buildings  

Science Conference Proceedings (OSTI)

The objective of this study is to perform an economic analysis of the daylight-linked automatic on/off lighting control system installed for the purpose of energy savings in office buildings. For this, a building was chosen as a typical example, and the energy cost was calculated by using the daylight and building energy analysis simulation. When the lighting control was utilized, an economic analysis was performed using a payback period that was calculated by comparing the initial cost of installing the lighting control system with the annual energy cost which was reduced thanks to the application of the lighting control. The results showed that the lighting energy consumption, when the lighting control was applied, was reduced by an average of 30.5% compared with the case that there was not lighting control applied. Also, the result for total energy consumption showed that, when lighting control was applied, this was reduced by 8.5% when the glazing ratio was 100%, 8.2% for 80%, and 7.6% for 60% when compared to non-application. The payback period was analyzed in terms of the number of floors in a building; 10 floors, 20 floors, 30 floors, and 40 floors. Hence, the building with 40 floors and glazing ratio 100% resulted in the shortest payback period of 8.8 years, the building with 10 floors and glazing ratio 60% resulted in the longest period of 12.7 years. In other words, the larger the glazing ratio and the number of building floors are, the shorter the payback period is. (author)

The design and evaluation of integrated envelope and lighting control strategies for commercial buildings  

SciTech Connect

This study investigates control strategies for coordinating the variable solar-optical properties of a dynamic building envelope system with a daylight controlled electric lighting system to reduce electricity consumption and increase comfort in the perimeter zone of commercial buildings. Control strategy design can be based on either simple, instantaneous measured data, or on complex, predictive algorithms that estimate the energy consumption for a selected operating state of the dynamic envelope and lighting system. The potential benefits of optimizing the operation of a dynamic envelope and lighting system are (1) significant reductions in electrical energy end-uses - lighting, and cooling due to solar and lighting heat gains - over that achieved by conventional static envelope and lighting systems, (2) significant reductions in peak demand, and (3) increased occupant visual and thermal comfort. The DOE-2 building energy simulation program was used to model two dynamic envelope and lighting systems, an automated venetian blind and an electrochromic glazing system, and their control strategies under a range of building conditions. The energy performance of simple control strategies are compared to the optimum performance of a theoretical envelope and lighting system to determine the maximum potential benefit of using more complex, predictive control algorithms. Results indicate that (1) predictive control algorithms may significantly increase the energy-efficiency of systems with non-optimal solar-optical properties such as the automated venetian blind, and (2) simpler, non-predictive control strategies may suffice for more advanced envelope systems 1 incorporating spectrally selective, narrow-band electrochromic coatings.

While these two thermal batteries have been engaged separately in the past, this project investigated the merits of harnessing both storage media concurrently in the context of predictive optimal control. To pursue the analysis, modeling, and simulation research of Phase 1, two separate simulation environments were developed. Based on the new dynamic building simulation program EnergyPlus, a utility rate module, two thermal energy storage models were added. Also, a sequential optimization approach to the cost minimization problem using direct search, gradient-based, and dynamic programming methods was incorporated. The objective function was the total utility bill including the cost of reheat and a time-of-use electricity rate either with or without demand charges. An alternative simulation environment based on TRNSYS and Matlab was developed to allow for comparison and cross-validation with EnergyPlus. The initial evaluation of the theoretical potential of the combined optimal control assumed perfect weather prediction and match between the building model and the actual building counterpart. The analysis showed that the combined utilization leads to cost savings that is significantly greater than either storage but less than the sum of the individual savings. The findings reveal that the cooling-related on-peak electrical demand of commercial buildings can be considerably reduced. A subsequent analysis of the impact of forecasting uncertainty in the required short-term weather forecasts determined that it takes only very simple short-term prediction models to realize almost all of the theoretical potential of this control strategy. Further work evaluated the impact of modeling accuracy on the model-based closed-loop predictive optimal controller to minimize utility cost.

Neuro-fuzzy control of an MDOF building with a magnetorheological damper using acceleration feedback  

E-Print Network (OSTI)

Parameter specification of a fuzzy inference system (HS) with the aid of artificial neural networks allows the creation of complex, multi-dimensional models that are computationally efficient and numerically robust. An adaptive neuro-fuzzy inference system (ANFIS) model is designed to emulate the dynamic behavior of an SD-1000 magnetorheological (MR) damper. The fuzzy damper model enables design and testing of semi-active control strategies within a numerical environment. Modern neuro-fuzzy design techniques are again used with the introduction of a new form of expert control. With this new method, fuzzy logic controllers (FLC) are developed to diminish seismically induced vibrations of single and multiple DOF buildings. The controllers specify a time varying voltage to be applied to MR dampers installed in the buildings. Determination of the voltage signal is based solely on acceleration feedback from the structure being controlled. Effectiveness of the RC is tested through a series of numerical simulations during which the building models are subjected to five different earthquake signals. Signal noise and time delays are found to have only a small effect on operation of the fuzzy controllers. For both structures, performance of the semi-active control scheme is compared with that of similarly scaled passive damping strategies. With regards to the SDOF building, it is determined that a passive control system is superior to a semi-active strategy of similar strength for reduction of lateral displacement and acceleration. For a majority of the tests involving the MDOF building, a semi-active scheme is found to be more beneficial than passive damping approachs for the reduction of lateral acceleration. Thus, more research in the use of MR dampers with tall buildings is advocated.

Parameters for structural vibration, building systems noise, acoustics and environmental noise crossing property boundaries will be presented with brief case studies illustrating noise and vibration problems with successful solutions. Building mechanical, power, and plumbing systems contribute to building operations noise and vibration, which affects building occupants, sensitive installations, and functional uses. Various noise and vibration design criteria, field measurements, design concepts and specifications can be applied in facilities to achieve noise mitigation and vibration control to enhance building operations and reduce tenant or neighbor problems. Concepts for enhancement will be presented that achieve specific program criteria and improve the built environment for occupants and functional uses, including items to incorporate in specifications and construction documents. Concepts relating to noise and vibration control can also reduce short and long-term operations costs and save energy. Acoustical designs can be implemented in new construction to achieve specific requirements for LEED certification in healthcare and educational facilities. Common problems, objective criteria, sensitive installations, and solutions will be presented to offer a basic understanding of effective noise and vibration control for central plant equipment, power systems, transformers, standby generators, and roof mounted HVAC equipment.

Coordinated Control and Optimization of Virtual Power Plants for Energy and Frequency Regulation Services in Electricity Markets  

E-Print Network (OSTI)

With increasing penetration of intermittent resources such as wind and solar, power system operations are facing much more challenges in cost effective provision of energy balancing and frequency regulation services. Enabled by advances in sensing, control and communication, the concept of Virtual Power Plant (VPP) is proposed as one possible solution which aggregates and firms up spatially distributed resources? net power injection to the system. This thesis proposes a coordinated control and bidding strategy for VPPs to provide energy balancing and grid frequency regulation services in electricity market environment. In this thesis, the VPP consists of two energy conversion assets: a Doubly Fed Induction Generator (DFIG)-based wind farm and a co-located Flywheel Energy Storage System (FESS). The coordination of the VPP is implemented through power electronics?based controllers. A five-bus system test case demonstrates the technical feasibility of VPPs to respond to grid frequency deviation as well as to follow energy dispatch signals. To enable the participation of VPPs in electricity market, this thesis also proposes an optimization based bidding strategy for VPPs in both energy balancing and frequency regulation service markets. The potential economic benefits of this bidding strategy are demonstrated under Denmark wholesale electricity market structure. Four case studies show the economic benefit of coordinating VPPs.

A Modelica-based Model Library for Building Energy and Control Systems  

SciTech Connect

This paper describes an open-source library with component models for building energy and control systems that is based on Modelica, an equation-based objectoriented language that is well positioned to become the standard for modeling of dynamic systems in various industrial sectors. The library is currently developed to support computational science and engineering for innovative building energy and control systems. Early applications will include controls design and analysis, rapid prototyping to support innovation of new building systems and the use of models during operation for controls, fault detection and diagnostics. This paper discusses the motivation for selecting an equation-based object-oriented language. It presents the architecture of the library and explains how base models can be used to rapidly implement new models. To demonstrate the capability of analyzing novel energy and control systems, the paper closes with an example where we compare the dynamic performance of a conventional hydronic heating system with thermostatic radiator valves to an innovative heating system. In the new system, instead of a centralized circulation pump, each of the 18 radiators has a pump whose speed is controlled using a room temperature feedback loop, and the temperature of the boiler is controlled based on the speed of the radiator pump. All flows are computed by solving for the pressure distribution in the piping network, and the controls include continuous and discrete time controls.

Using Remote Control Systems for the Re-Commissioning of Heating Plants of School Building  

E-Print Network (OSTI)

The objective of this work is to develop a semi-automatic commissioning tool that can be implemented in Remote Control Systems to help building operators test the performance of heating plants in school buildings. The work was carried out with the city of Paris and the tool was adapted to the requirements of end-users who are operating more than 700 schools. This semi-automatic commissioning tool could help to reduce costs and time for commissioning tasks of a large number of buildings. It also helps to improve the commissioning process, to have a whole building functional testing approach and make the commissioning procedure available for different users with different skills. This work was carried out as part of an IEA Annex 40 research project, an international research group focused on energy saving technologies and activities that support their application in practice.

Energy Performance Evaluation and Development of Control Strategies for the Air-conditioning System of a Building at Construction Stage  

E-Print Network (OSTI)

Energy consumption of HVAC systems in commercial buildings takes a great part of the total building energy consumption. Energy performance evaluation plays an important role in building energy efficiency improvement for existing buildings and new buildings. It is also the basis for the retrofitting measure evaluation for existing buildings and the control improvement evaluation of new buildings for building energy performance contracts. In this study, the energy performance evaluation of a super high-rising commercial office building in construction is presented. Alternative control strategies are proposed to improve the energy efficiency based on the current measurements of the original design as well as additional metering instruments as requested. These control strategies mainly involve optimal chiller sequencing control, cooling tower sequencing control, optimal water pressure differential set-point control, AHU supply air static pressure reset control and DCV-based fresh air control, etc. To assess the economic feasibility, the benchmark electricity consumption and the optimal electricity consumption using alternative controls strategies are estimated using dynamic simulations. The results show that the electricity savings using the alternative control strategies can cover the costs of an additional metering system and related software and hardware in about one year.

Simulation-based assessment of the energy savings benefits of integrated control in office buildings  

SciTech Connect

The purpose of this study is to use existing simulation tools to quantify the energy savings benefits of integrated control in office buildings. An EnergyPlus medium office benchmark simulation model (V1.0_3.0) developed by the Department of Energy (DOE) was used as a baseline model for this study. The baseline model was modified to examine the energy savings benefits of three possible control strategies compared to a benchmark case across 16 DOE climate zones. Two controllable subsystems were examined: (1) dimming of electric lighting, and (2) controllable window transmission. Simulation cases were run in EnergyPlus V3.0.0 for building window-to-wall ratios (WWR) of 33percent and 66percent. All three strategies employed electric lighting dimming resulting in lighting energy savings in building perimeter zones ranging from 64percent to 84percent. Integrated control of electric lighting and window transmission resulted in heating, ventilation, and air conditioning (HVAC) energy savings ranging from ?1percent to 40percent. Control of electric lighting and window transmission with HVAC integration (seasonal schedule of window transmission control) resulted in HVAC energy savings ranging from 3percent to 43percent. HVAC energy savings decreased moving from warm climates to cold climates and increased when moving from humid, to dry, to marine climates.

Total Facility Control - Applying New Intelligent Technologies to Energy Efficient Green Buildings  

E-Print Network (OSTI)

Energy efficiency through intelligent control is a core element of any "Green Building". We need smarter, more efficient ways of managing the energy consuming elements within a building. But what we think of as "the building" is only a small piece of the puzzle. We have to think broader in order to gain the greater energy savings and efficiencies that are possible. "Total Facility Control" is a concept that we need to embrace and consider when we design, commission, and retrofit our facilities. Very often a single building is part of a larger campus or collection of buildings under a common management domain. Be it a university, public school district, office complex, or multiuse tenant space, there are often multiple "buildings" plus the connectivity between buildings: walkway lighting, signage, parking structures, and even the irrigation systems. We don't often think about the outdoor lighting, security, or irrigation as part of the building management plan, but it can be a significant contributing factor when looking at places to save on energy and improve operational efficiency. We must change the way we design our buildings, facilities, campuses, and enterprises in order to be more energy efficient and be green. A variety of technologies and design principles are available to ensure we move in a positive direction. We must make our systems and processes more visible and, hence, more accessible. At the core of this is the visibility and control of the systems within these environments. A majority of the building control systems in operation today are extremely limited in their ability to achieve higher efficiencies because there is no intelligent control or communication system available; and the amount of cross system interoperability is even scarcer. What does an interoperable system architecture look like? It's one in which a wide variety of energy consuming, intelligent devices can share their information and be controlled by an energy management system. Newer technologies use open systems, open protocols, and higher levels of interoperability, all of which have been proven to cost effectively provide competitive solutions. Better energy efficiency and improved operational costs start with better visibility and control of the myriad of systems within a facility. They must communicate together in a way that enables greater functionality and lower costs. Total Facility Control must be considered as we look at the entire building envelope as well as the rest of the facility systems. Included in the mix are HVAC, indoor lighting, security, access, sun shading, indoor air quality, sound masking and alarm annunciation, elevators/escalators, appliances, power conditioning, irrigation, energy metering, outdoor/parking lot lighting, street lighting, co-generation stations, and much more. This paper will discuss some of the basic concepts, architectures, and technologies that are being used today to implement a Total Facility Control model.

DOE Patents (OSTI)

A system for visualizing, controlling and managing information includes a data analysis unit for interpreting and classifying raw data using analytical techniques. A data flow coordination unit routes data from its source to other components within the system. A data preparation unit handles the graphical preparation of the data and a data rendering unit presents the data in a three-dimensional interactive environment where the user can observe, interact with, and interpret the data. A user can view the information on various levels, from a high overall process level view, to a view illustrating linkage between variables, to view the hard data itself, or to view results of an analysis of the data. The system allows a user to monitor a physical process in real-time and further allows the user to manage and control the information in a manner not previously possible.

A Control Scheme of Enhanced Reliability for Multiple Chiller Plants Using Mergerd Building Cooling Load Measurements  

E-Print Network (OSTI)

This paper presents a control scheme which utilizes the enhanced instantaneous cooling load measurements to improve the reliability of chiller sequencing control. The enhanced measurement is obtained by merging two different measurements of building cooling load using data fusion technique. One is the direct cooling load measurement, which is obtained directly using the differential water temperature and water flow rate measurements. The other is the indirect cooling load measurement, which estimates the cooling load using chiller models based on the instantaneous chiller electrical power input and condition measured variables. The control performance of the proposed scheme is validated in this paper.

Humidity Control Systems for Civil Buildings in Hot Summer and Cold Winter Zone in China  

E-Print Network (OSTI)

In the hot summer and cold winter zone, moisture-laden outside air poses real problems for proper ventilation, air-conditioner sizing, and strategies to overcome the reduced dehumidification capacity of more energy-efficient air-conditioning (AC) systems. Based on our research, this paper further provides the rate and characteristics of moisture resources in civil buildings. Although the ventilation rate is limited with the minimum ventilation rate in the sanitation ventilation mode of the air conditioning period, dehumidifying period and heating period, the ventilation rate is unrestricted in thermal comfort ventilation mode. It is suggested that the operating conditions of the forced ventilation system should be determined on both outdoor air temperature and outdoor air relative humidity (RH). Therefore, the ventilation system should satisfy these requirements during prolonged periods of high ambient humidity. After a detailed presentation of the technical issues, this paper gives specific recommendations for providing adequate ventilation, moisture control and dehumidifying for buildings in hot-humid climates, and takes both the indoor environmental quality (IEQ) and the building energy efficiency into account. Supplying conditioned ventilation air to the buildings appears to be a promising approach to solve the heath problems associated with excessive indoor RH by installation of a separately controlled unit to dry and cool outdoor air.

Unhappy with internal corporate search? : learn tips and tricks for building a controlled vocabulary ontology.  

SciTech Connect

Are your employees unhappy with internal corporate search? Frequent complaints include: too many results to sift through; results are unrelated/outdated; employees aren't sure which terms to search for. One way to improve intranet search is to implement a controlled vocabulary ontology. Employing this takes the guess work out of searching, makes search efficient and precise, educates employees about the lingo used within the corporation, and allows employees to contribute to the corpus of terms. It promotes internal corporate search to rival its superior sibling, internet search. We will cover our experiences, lessons learned, and conclusions from implementing a controlled vocabulary ontology at Sandia National Laboratories. The work focuses on construction of this ontology from the content perspective and the technical perspective. We'll discuss the following: (1) The tool we used to build a polyhierarchical taxonomy; (2) Examples of two methods of indexing the content: traditional 'back of the book' and folksonomy word-mapping; (3) Tips on how to build future search capabilities while building the basic controlled vocabulary; (4) How to implement the controlled vocabulary as an ontology that mimics Google's search suggestions; (5) Making the user experience more interactive and intuitive; and (6) Sorting suggestions based on preferred, alternate and related terms using SPARQL queries. In summary, future improvements will be presented, including permitting end-users to add, edit and remove terms, and filtering on different subject domains.

Roots of Mold Problems and Humidity Control Measures in Institutional Buildings with Pre-Existing Mold Condition  

E-Print Network (OSTI)

Humidity control and mold in buildings has become an increasingly important problem. Once a building has experience mold growth on walls, ceilings, and other surfaces, it does not take longterm exposure to moisture for mold to re-grow in the building. Some commercial buildings on the Texas A&M University (TAMU) campus have suffered with humidity problems for many years. The Continuous Commissioning (CCSM) group of the Energy Systems Lab in collaboration with the Utilities Office of Energy Management, and the TAMU Physical Plant, was dispatched to perform Continuous Commissioning on these commercial buildings in order to find viable solutions to the humidity problem. The CC group performed extensive field tests and analysis on building air handling unit (AHU), exhaust systems, building construction, and the Energy Management Control System (EMCS). Based on the field studies and analysis, a four-category (Design, construction, building retrofits and alterations, and poor maintenance) system was set up to classify sources for high humidity problems. This paper presents the investigation and follow-up efforts, which identified reasons and corrective measures for the high humidity levels in these buildings, turning these inefficient and humid commercial buildings into comfortable environments. Recommendations for dealing with such possible problems are provided.

Improving Building Control and System Operation Through the Continuous Commissioning® Process: A Case Study  

E-Print Network (OSTI)

Utilization of the Continuous Commissioning® process is presented in the case of the Consolidated Mission Support Center office building at Travis Air Force Base in Travis, California. The CC® process was applied to the building in early 2003. The examination of the heating, ventilating, and airconditioning (HVAC) and control systems revealed several areas where considerable improvement could be made, including air handling unit (AHU) operational parameters, terminal box and water loop operation, and Energy Management and Control System (EMCS) functionality. It also aided in the identification of mechanical systems needing repair. The optimization of the HVAC systems and advanced utilization of the EMCS reduced the combined heating and cooling energy consumption by 26% without capital intensive upgrades. Cooling energy decreased by 10%, heating energy was cut by over 40%, and fan power decreased by 28%. A hidden benefit to the implementation of the CC® process is the reduction in the human capital required to operate the building. Prior to commissioning, significant time was spent changing system operating setpoints in an attempt to save energy. These efforts are no longer required.

The use of energy management and control systems to monitor the energy performance of commercial buildings  

SciTech Connect

Monitored data play a very important part in the implementation and evaluation of energy conservation technologies and programs. However, these data can be expensive to collect, so there is a need for lower-cost alternatives. In many situations, using the computerized Energy Management and Control Systems (EMCSs)--already installed in many buildings--to collect these commercial building performance data has advantages over more conventional methods. This method provides data without installing incremental hardware, and the large amounts of available operational data can be a very rich resource for understanding building performance. This dissertation addresses several of these issues. One specific objective is to describe a monitoring-project planning process that includes definition of objectives, constraints, resources and approaches for the monitoring. The choice of tools is an important part of this process. The dissertation goes on to demonstrate, through eight case studies, that EMCS monitoring is possible, and to identify and categorize the problems and issues that can be encountered. These issues lead to the creation, use, and testing of a set of methods for evaluation of EMCS monitoring, in the form of guidelines. Finally, EMCS monitoring is demonstrated and compared with conventional monitoring more methodically in a detailed case study.

Recommended Changes to Specifications for Demand Controlled Ventilation in California's Title 24 Building Energy Efficiency Standards  

SciTech Connect

In demand-controlled ventilation (DCV), rates of outdoor air ventilation are automatically modulated as occupant density varies. The objective is to keep ventilation rates at or above design specifications and code requirements and also to save energy by avoiding excessive ventilation rates. DCV is most often used in spaces with highly variable and sometime dense occupancy. In almost all cases, carbon dioxide (CO{sub 2}) sensors installed in buildings provide the signal to the ventilation rate control system. People produce and exhale CO{sub 2} as a consequence of their normal metabolic processes; thus, the concentrations of CO{sub 2} inside occupied buildings are higher than the concentrations of CO{sub 2} in the outdoor air. The magnitude of the indoor-outdoor CO{sub 2} concentration difference decreases as the building's ventilation rate per person increases. The difference between the indoor and outdoor CO{sub 2} concentration is also a proxy for the indoor concentrations of other occupant-generated bioeffluents, such as body odors. Reviews of the research literature on DCV indicate a significant potential for energy savings, particularly in buildings or spaces with a high and variable occupancy. Based on modeling, cooling energy savings from applications of DCV are as high as 20%. With support from the California Energy Commission and the U.S. Department of Energy, the Lawrence Berkeley National Laboratory has performed research on the performance of CO{sub 2} sensing technologies and optical people counters for DCV. In addition, modeling was performed to evaluate the potential energy savings and cost effectiveness of using DCV in general office spaces within the range of California climates. The above-described research has implications for the specifications pertaining to DCV in section 121 of the California Title 24 Standard. Consequently, this document suggests possible changes in these specifications based on the research findings. The suggested changes in specifications were developed in consultation with staff from the Iowa Energy Center who evaluated the accuracy of new CO{sub 2} sensors in laboratory-based research. In addition, staff of the California Energy Commission, and their consultants in the area of DCV, provided input for the suggested changes in specifications.

Evaluation of Humidity Control Options in Hot-Humid Climate Homes (Fact Sheet), Building America: Technical Highlight, Building Technologies Program (BTP)  

NLE Websites -- All DOE Office Websites (Extended Search)

Humidity Control Options in Hot-Humid Climate Homes As the Building America program researches construction of homes that achieve greater source energy savings over typical mid-1990s construction, proper modeling of whole-house latent loads and operation of humidity control equipment has become a high priority. Long-term high relative humidity can cause health and durability problems in homes, particularly in a hot-humid climate. In this study, researchers at the National Renewable Energy Laboratory (NREL) used the latest EnergyPlus tool equipped with the moisture capacitance model to analyze the indoor relative humidity in three home types: a Building America high-performance home; a mid- 1990s reference home; and a 2006 International Energy Conservation

Building a simulator control station using the TCL/TK language  

SciTech Connect

This paper describes the construction of a simulator graphical user interface (GUI) using the cross-platform, public domain programming language TCL/TK. TCL/TK is a high level scripting language for building GUIs. It is freely available for UNIX, Windows and the Mac operating systems. This paper will demonstrate how the traditionally difficult, time consuming aspects of producing a simulator control station are easily overcome with TCL/TK. Referred to as the Interactive Control Station (ICS), this user interface provides a graphical method for interactive control of real time applications produced with the Real Time Programming Environment (RTProE). The techniques and tools developed for connecting the ICS to real time simulator models are described in detail within the paper. The real time data collection and plotting tool included with the ICS is also discussed. The ICS uses a client/server design and can provide its features across a distributed computer network. Standard TCP/IP sockets are used as the communications transport medium. Multiple clients on a network may be served by a single server connected to the simulation. The clients may exist on the same or separate computers. Multiple servers, connected to different simulations, can also exist on the same or separate computers of the network.

Application Study of the Pump Water Flow Station for Building Energy Consumption Monitoring and Control Optimization  

E-Print Network (OSTI)

This paper presents a new building energy monitoring and pump speed control method. The pump speed is controlled to maintain the system resistance at an optimized value to approach the best pump efficiency and save pump power. The system resistance can be obtained by the pump head and the water flow rate calculated by the pump water-flow station (PWS), which was recently developed. The PWS measures the water flow rate using the pump head, pump speed, and pump performance curve. This method has been experimentally proved in real HVAC systems. A case study was demonstrated in this paper for application of this new method in a Continuous Commissioning (CC) practice. The case study shows that the PWS can control the pump speed to maintain the optimized system operating point. It can also measure the water flow rate and monitor energy consumption continuously with low installation and almost no maintenance cost. The results show that the new technology can save pump power and increase pump efficiency significantly.

Virtual Laboratories  

E-Print Network (OSTI)

At the frontier of most areas in science, computer simulations play a central role. The traditional division of natural science into experimental and theoretical investigations is now completely outdated. Instead, theory, simulation, and experimentation form three equally essential aspects, each with its own unique flavor and challenges. Yet, education in computational science is still lagging far behind, and the number of text books in this area is minuscule compared to the many text books on theoretical and experimental science. As a result, many researchers still carry out simulations in a haphazard way, without properly setting up the computational equivalent of a well equipped laboratory. The art of creating such a virtual laboratory, while providing proper extensibility and documentation, is still in its infancy. A new approach is described here, Open Knowledge, as an extension of the notion of Open Source software. Besides open source code, manuals, and primers, an open knowledge project provides simulated dialogues between code developers, thus sharing not only the code, but also the motivations behind the code.

The Chilled Water and Hot Water Building Differential Pressure Setpoint Calculation - Chilled Water and Hot Water Pump Speed Control  

E-Print Network (OSTI)

More and more variable frequency devices (VFD) are being installed on the chilled water and hot water pumps on the TAMU campus. Those pump speeds are varied to maintain chilled water or hot water building deferential pressure (DP) or return temperature or flow rate at their setpoints. The chilled water and hot water DP setpoint or return temperature setpoint or flow rate setpoint was a constant value or reset based on outside air temperature. In some buildings, the chilled water and hot water DP setpoints were reset based on flow rate, but in many instances those setpoint schedules were either too low to maintain enough building DP requirement or too high and consumed excess energy. The building DP reset schedule based on flow rate is studied and compared with the other pump speed control methods. Because the building DP setpoint based on flow rate method is achieved by tracking the load change, it saves energy than the other methods. In this paper its calculation procedure is generated and the example of the building DP calculation is given.

Virtual PCR  

Science Conference Proceedings (OSTI)

The polymerase chain reaction (PCR) stands among the keystone technologies for analysis of biological sequence data. PCR is used to amplify DNA, to generate many copies from as little as a single template. This is essential, for example, in processing forensic DNA samples, pathogen detection in clinical or biothreat surveillance applications, and medical genotyping for diagnosis and treatment of disease. It is used in virtually every laboratory doing molecular, cellular, genetic, ecologic, forensic, or medical research. Despite its ubiquity, we lack the precise predictive capability that would enable detailed optimization of PCR reaction dynamics. In this LDRD, we proposed to develop Virtual PCR (VPCR) software, a computational method to model the kinetic, thermodynamic, and biological processes of PCR reactions. Given a successful completion, these tools will allow us to predict both the sequences and concentrations of all species that are amplified during PCR. The ability to answer the following questions will allow us both to optimize the PCR process and interpret the PCR results: What products are amplified when sequence mixtures are present, containing multiple, closely related targets and multiplexed primers, which may hybridize with sequence mismatches? What are the effects of time, temperature, and DNA concentrations on the concentrations of products? A better understanding of these issues will improve the design and interpretation of PCR reactions. The status of the VPCR project after 1.5 years of funding is consistent with the goals of the overall project which was scoped for 3 years of funding. At half way through the projected timeline of the project we have an early beta version of the VPCR code. We have begun investigating means to improve the robustness of the code, performed preliminary experiments to test the code and begun drafting manuscripts for publication. Although an experimental protocol for testing the code was developed, the preliminary experiments were tainted by contaminated products received from the manufacturer. Much knowledge has been gained in the development of the code thus far, but without final debugging, increasing its robustness and verifying it against experimental results, the papers which we have drafted to share our findings still require the final data necessary for publication. The following sections summarize our final progress on VPCR as it stands after 1.5 years of effort on an ambitious project scoped for a 3 year period. We have additional details of the methods than are provided here, but would like to have legal protection in place before releasing them. The result of this project, a suite of programs that predict PCR products as a function of reaction conditions and sequences, will be used to address outstanding questions in pathogen detection and forensics at LLNL. VPCR should enable scientists to optimize PCR protocols in terms of time, temperature, ion concentration, and primer sequences and concentrations, and to estimate products and error rates in advance of performing experiments. Our proposed capabilities are well ahead of all currently available technologies, which do not model non-equilibrium kinetics, polymerase extension, or predict multiple or undesired PCR products. We are currently seeking DHS funding to complete the project, at which time licensing opportunities will be explored, an updated patent application will be prepared, and a publication will be submitted. A provisional and a full patent application have already been filed (1).

Final Scientific Technical Report: INTEGRATED PREDICTIVE DEMAND RESPONSE CONTROLLER FOR COMMERCIAL BUILDINGS  

SciTech Connect

This project provides algorithms to perform demand response using the thermal mass of a building. Using the thermal mass of the building is an attractive method for performing demand response because there is no need for capital expenditure. The algorithms rely on the thermal capacitance inherent in the building?s construction materials. A near-optimal ?day ahead? predictive approach is developed that is meant to keep the building?s electrical demand constant during the high cost periods. This type of approach is appropriate for both time-of-use and critical peak pricing utility rate structures. The approach uses the past days data in order to determine the best temperature setpoints for the building during the high price periods on the next day. A second ?model predictive approach? (MPC) uses a thermal model of the building to determine the best temperature for the next sample period. The approach uses constant feedback from the building and is capable of appropriately handling real time pricing. Both approaches are capable of using weather forecasts to improve performance.

Reasons include faulty construction, malfunctioning equipment, incorrectly configured control systems and inappropriate operating procedures. One approach to addressing this problems is to compare the predictions of an energy simulation model of the building to the measured performance and analyze significant differences to infer the presence and location of faults. This paper presents a framework that allows a comparison of building actual performance and expected performance in real time. The realization of the framework utilized the EnergyPlus, the Building Controls Virtual Test Bed (BCVTB) and the Energy Management and Control System (EMCS) was developed. An EnergyPlus model that represents expected performance of a building runs in real time and reports the predicted building performance at each time step. The BCVTB is used as the software platform to acquire relevant inputs from the EMCS through a BACnet interface and send them to the EnergyPlus and to a database for archiving. A proof-of-concept demonstration is also presented.

Modelica-based Modeling and Simulation to Support Research and Development in Building Energy and Control Systems  

SciTech Connect

Traditional building simulation programs possess attributes that make them difficult to use for the design and analysis of building energy and control systems and for the support of model-based research and development of systems that may not already be implemented in these programs. This article presents characteristic features of such applications, and it shows how equation-based object-oriented modelling can meet requirements that arise in such applications. Next, the implementation of an open-source component model library for building energy systems is presented. The library has been developed using the equation-based object-oriented Modelica modelling language. Technical challenges of modelling and simulating such systems are discussed. Research needs are presented to make this technology accessible to user groups that have more stringent requirements with respect to the numerical robustness of simulation than a research community may have. Two examples are presented in which models from the here described library were used. The first example describes the design of a controller for a nonlinear model of a heating coil using model reduction and frequency domain analysis. The second example describes the tuning of control parameters for a static pressure reset controller of a variable air volume flow system. The tuning has been done by solving a non-convex optimization problem that minimizes fan energy subject to state constraints.

Plug-Load Control and Behavioral Change Research in GSA Office Buildings  

SciTech Connect

The U.S. General Services Administration (GSA) owns and leases over 354 million square feet (ft2) of space in over 9,600 buildings [1]. GSA is a leader among federal agencies in aggressively pursuing energy efficiency (EE) opportunities for its facilities and installing renewable energy (RE) systems to provide heating, cooling, and power to these facilities. According to several energy assessments of GSA's buildings conducted by the National Renewable Energy Laboratory (NREL), plug-loads account for approximately 21% of the total electricity consumed within a standard GSA Region 3 office building. This study aims to provide insight on how to effectively manage plug-load energy consumption and attain higher energy and cost savings for plug-loads. As GSA improves the efficiency of its building stock, plug-loads will become an even greater portion of its energy footprint.

Key Residential Building Equipment Technologies for Control and Grid Support PART I (Residential)  

Science Conference Proceedings (OSTI)

Electrical energy consumption of the residential sector is a crucial area of research that has in the past primarily focused on increasing the efficiency of household devices such as water heaters, dishwashers, air conditioners, and clothes washer and dryer units. However, the focus of this research is shifting as objectives such as developing the smart grid and ensuring that the power system remains reliable come to the fore, along with the increasing need to reduce energy use and costs. Load research has started to focus on mechanisms to support the power system through demand reduction and/or reliability services. The power system relies on matching generation and load, and day-ahead and real-time energy markets capture most of this need. However, a separate set of grid services exist to address the discrepancies in load and generation arising from contingencies and operational mismatches, and to ensure that the transmission system is available for delivery of power from generation to load. Currently, these grid services are mostly provided by generation resources. The addition of renewable resources with their inherent variability can complicate the issue of power system reliability and lead to the increased need for grid services. Using load as a resource, through demand response programs, can fill the additional need for flexible resources and even reduce costly energy peaks. Loads have been shown to have response that is equal to or better than generation in some cases. Furthermore, price-incentivized demand response programs have been shown to reduce the peak energy requirements, thereby affecting the wholesale market efficiency and overall energy prices. The residential sector is not only the largest consumer of electrical energy in the United States, but also has the highest potential to provide demand reduction and power system support, as technological advancements in load control, sensor technologies, and communication are made. The prevailing loads based on the largest electrical energy consumers in the residential sector are space heating and cooling, washer and dryer, water heating, lighting, computers and electronics, dishwasher and range, and refrigeration. As the largest loads, these loads provide the highest potential for delivering demand response and reliability services. Many residential loads have inherent flexibility that is related to the purpose of the load. Depending on the load type, electric power consumption levels can either be ramped, changed in a step-change fashion, or completely removed. Loads with only on-off capability (such as clothes washers and dryers) provide less flexibility than resources that can be ramped or step-changed. Add-on devices may be able to provide extra demand response capabilities. Still, operating residential loads effectively requires awareness of the delicate balance of occupants health and comfort and electrical energy consumption. This report is Phase I of a series of reports aimed at identifying gaps in automated home energy management systems for incorporation of building appliances, vehicles, and renewable adoption into a smart grid, specifically with the intent of examining demand response and load factor control for power system support. The objective is to capture existing gaps in load control, energy management systems, and sensor technology with consideration of PHEV and renewable technologies to establish areas of research for the Department of Energy. In this report, (1) data is collected and examined from state of the art homes to characterize the primary residential loads as well as PHEVs and photovoltaic for potential adoption into energy management control strategies; and (2) demand response rules and requirements across the various demand response programs are examined for potential participation of residential loads. This report will be followed by a Phase II report aimed at identifying the current state of technology of energy management systems, sensors, and communication technologies for demand response and load factor control applications

Roof aperture system for selective collection and control of solar energy for building heating, cooling and daylighting  

DOE Patents (OSTI)

The amount of building heating, cooling and daylighting is controlled by at least one pair of solar energy passing panels, with each panel of the pair of panels being exposed to a separate direction of sun incidence. A shutter-shade combination is associated with each pair of panels and the shutter is connected to the shade so that rectilinear movement of the shutter causes pivotal movement of the shade.

Improving Building Comfort and Energy Savings of the McKenzie Airport Terminal by Maintaining and Improving Pneumatic Control Systems  

E-Print Network (OSTI)

McKenzie Airport Terminal is located at Easterwood Airport, which is owned and operated by Texas A&M University. It was built in 1988. Most all HVAC equipment, which includes boiler, chiller, pumps, AHUs and exhaust fans, due to lack of maintenance, had some form of deteriorated controls, components, and operational function. For example, most of pneumatic controls were failed due to bad components, wrong settings, and disconnection before the Continuous CommissioningR (CCSM). This caused humid and hot problems of the building, and wasted energy. After maintaining and improving the pneumatic controls, the boiler and hot water pump is now turned off when outside air temperature is higher than 80°F. The chiller is now shut off when the outside air temperature is below 55 °F, and the economizers activate to maintain discharge air temperature when the outside air temperature is below 60 °F. The building comfort in temperature and relative humidity (RH) is improved after CCSM. For example, average space temperature of the building was above 75 °F most of the time before CCSM and is now 73 °F after CCSM. The relative humidity in the baggage claim area was 70% before CCSM and is now 55% after CCSM. The annual savings of electricity for chiller and natural gas for boiler are $5,040 and $12,090 respectively. The total annual energy savings are $17,130.

A method of optimizing solar control and daylighting performance in commercial office buildings  

SciTech Connect

We present a method for analyzing the annual cooling and lighting electricity use and peak demand associated with varying fenestration and lighting strategies in commercial office buildings. A prototypical office building module consisting of four perimeter zones and a central core zone was defined and a series of DOE-2 building energy simulations were completed to create a data base for varying fenestration and lighting system parameters. Using regression analysis procedures, we characterize energy and peak performance patterns as a function of solar aperture, defined as the product of shading coefficient and window-to-wall ratio, and effective daylighting aperture, defined as the product of visible transmittance and window-to-wall ratio. Optimum performance consists of defining the solar and effective daylighting aperture values that minimize annual energy consumption and peak demand, a process easily facilitated by the methods described herein.

Application of the Software as a Service Model to the Control of Complex Building Systems  

Science Conference Proceedings (OSTI)

In an effort to create broad access to its optimization software, Lawrence Berkeley National Laboratory (LBNL), in collaboration with the University of California at Davis (UC Davis) and OSISoft, has recently developed a Software as a Service (SaaS) Model for reducing energy costs, cutting peak power demand, and reducing carbon emissions for multipurpose buildings. UC Davis currently collects and stores energy usage data from buildings on its campus. Researchers at LBNL sought to demonstrate that a SaaS application architecture could be built on top of this data system to optimize the scheduling of electricity and heat delivery in the building. The SaaS interface, known as WebOpt, consists of two major parts: a) the investment& planning and b) the operations module, which builds on the investment& planning module. The operational scheduling and load shifting optimization models within the operations module use data from load prediction and electrical grid emissions models to create an optimal operating schedule for the next week, reducing peak electricity consumption while maintaining quality of energy services. LBNL's application also provides facility managers with suggested energy infrastructure investments for achieving their energy cost and emission goals based on historical data collected with OSISoft's system. This paper describes these models as well as the SaaS architecture employed by LBNL researchers to provide asset scheduling services to UC Davis. The peak demand, emissions, and cost implications of the asset operation schedule and investments suggested by this optimization model are analysed.

Wireless Infrastructure for Performing Monitoring, Diagnostics, and Control HVAC and Other Energy-Using Systems in Small Commercial Buildings  

Science Conference Proceedings (OSTI)

This project focused on developing a low-cost wireless infrastructure for monitoring, diagnosing, and controlling building systems and equipment. End users receive information via the Internet and need only a web browser and Internet connection. The system used wireless communications for: (1) collecting data centrally on site from many wireless sensors installed on building equipment, (2) transmitting control signals to actuators and (3) transmitting data to an offsite network operations center where it is processed and made available to clients on the Web (see Figure 1). Although this wireless infrastructure can be applied to any building system, it was tested on two representative applications: (1) monitoring and diagnostics for packaged rooftop HVAC units used widely on small commercial buildings and (2) continuous diagnosis and control of scheduling errors such as lights and equipment left on during unoccupied hours. This project developed a generic infrastructure for performance monitoring, diagnostics, and control, applicable to a broad range of building systems and equipment, but targeted specifically to small to medium commercial buildings (an underserved market segment). The proposed solution is based on two wireless technologies. The first, wireless telemetry, is used for cell phones and paging and is reliable and widely available. This risk proved to be easily managed during the project. The second technology is on-site wireless communication for acquiring data from sensors and transmitting control signals. The technology must enable communication with many nodes, overcome physical obstructions, operate in environments with other electrical equipment, support operation with on-board power (instead of line power) for some applications, operate at low transmission power in license-free radio bands, and be low cost. We proposed wireless mesh networking to meet these needs. This technology is relatively new and has been applied only in research and tests. This proved to be a major challenge for the project and was ultimately abandoned in favor of a directly wired solution for collecting sensor data at the building. The primary reason for this was the relatively short ranges at which we were able to effectively place the sensor nodes from the central receiving unit. Several different mesh technologies were attempted with similar results. Two hardware devices were created during the original performance period of the project. The first device, the WEB-MC, is a master control unit that has two radios, a CPU, memory, and serves as the central communications device for the WEB-MC System (Currently called the 'BEST Wireless HVAC Maintenance System' as a tentative commercial product name). The WEB-MC communicates with the local mesh network system via one of its antennas. Communication with the mesh network enables the WEB-MC to configure the network, send/receive data from individual motes, and serves as the primary mechanism for collecting sensor data at remote locations. The second antenna enables the WEB-MC to connect to a cellular network ('Long-Haul Communications') to transfer data to and from the NorthWrite Network Operations Center (NOC). A third 'all-in-one' hardware solution was created after the project was extended (Phase 2) and additional resources were provided. The project team leveraged a project funded by the State of Washington to develop a hardware solution that integrated the functionality of the original two devices. The primary reason for this approach was to eliminate the mesh network technical difficulties that severely limited the functionality of the original hardware approach. There were five separate software developments required to deliver the functionality needed for this project. These include the Data Server (or Network Operations Center), Web Application, Diagnostic Software, WEB-MC Embedded Software, Mote Embedded Software. Each of these developments was necessarily dependent on the others. This resulted in a challenging management task - requiring high bandwidth communications among

Database Supported Bacnet Data Acquisition System for Building Energy Diagnostics  

E-Print Network (OSTI)

This paper reports a tool that can be used to acquire and store the BACnet (A Data Communication Protocol for Building Automation and Control Networks) data for the purpose of building energy system Fault Detection and Diagnostics (FDD). Building Automation Control (BAC) systems have become a common practice in recently constructed buildings in the United States. Although building operational data could readily be collected for various analysis purposes, there is still a debate in building community which or what FDD method is better in terms of performance matrix, such as false alarm rate and training data requirement, etc. Therefore, from the user's perspective, it is potentially beneficial to try out different FDD methods before the deployment, or even develop a dedicated FDD method in a specific case. This is the motivation for development of the BACnet data storage system discussed in this paper, which could then be used together with BACnet data acquisition module in an open source Building Control Virtual Test Bed (BCVTB) environment [2]. This paper discusses (1) Relational database schema development for the purpose of storing building operational data and FDD analysis data (2) Development of the connector in BCVTB that enables the transition from the BACnet module to the database module and (3)Testing of the integrated system in a real building. The relational database is intended to be general and detailed enough so that it can be applied to different buildings and projects with various complexity without any major structure change. The BACnet-reader to database connector enables seamless data flow from commercial BACnet system to user's customized workstation. The integrated system enables users to analyze building operational data in an effective and efficient way, which helps achieve automated FDD in buildings.

Home-based Shared Virtual Memory  

E-Print Network (OSTI)

In this dissertation, I investigate how to improve the performance of shared virtual memory (SVM) by examining consistency models, protocols, hardware support and applications. The main conclusion of this research is that the performance of shared virtual memory can be significantly improved when performance-enhancing techniques from all these areas are combined. This dissertation proposes home-based lazy release consistency as a simple, effective, and scalable way to build shared virtual memory systems. In home-based protocols each shared page has a home to which all writes are propagated and from which all copies are derived. Two home-based protocols are described, implemented and evaluated on two hardware and software platforms: Automatic Update Release Consistency (AURC), which requires hardware support for fine-grained remote writes (automatic updates), and Homebased Lazy Release Consistency (HLRC), which is implemented exclusively in software.

DEMONSTRATION OF A HYBRID INTELLIGENT CONTROL STRATEGY FOR CRITICAL BUILDING HVAC SYSTEMS  

SciTech Connect

Many industrial facilities utilize pressure control gradients to prevent migration of hazardous species from containment areas to occupied zones, often using Proportional-Integral-Derivative (PID) control. Within these facilities, PID control is often inadequate to maintain desired performance due to changing operating conditions. As the goal of the Heating, Ventilation and Air-Conditioning (HVAC) control system is to optimize the pressure gradients and associated flows for the plant, Linear Quadratic Tracking (LQT) provides a time-based approach to guiding plant interactions. However, LQT methods are susceptible to modeling and measurement errors, and therefore a hybrid design using the integration of soft control methods with hard control methods is developed and demonstrated to account for these errors and nonlinearities.

Optics and materials research for controlled radiant energy transfer in buildings. Final technical report  

DOE Green Energy (OSTI)

The primary objective of this project was to perform the optics and materials research necessary to identify and solve the technical problems associated with fabricating durable, variable reflectivity electrochromic windows for energy efficient buildings and vehicles. The research performed at the Tufts Electro-Optics Technology Center (EOTC) has identified and solved nearly all the significant problems, as discussed below in this final technical report. There still remains, however, one important problem to be solved--i.e., to better understand the science of deposition processes and thereby develop and optimize one or more production-worthy deposition processes that could be used for the practical production of affordable, variable reflectivity electrochromic windows. Therefore, it is recommended that such studies be carried out with the goals of: (1) determining the probable practical limits of performance; and, very importantly, (2) to develop and optimize deposition processes that could be used for the practical production of affordable electrochromic windows.

Automated energy management systems for small buildings. Final report, Volume 1: technical document  

SciTech Connect

Energy controls can perform a valuable function in energy conservation or energy-management strategy in buildings. While the more-simple controls can be applied to virtually any building, the more-complex automation systems are currently available only to large buildings where their greater costs may be justified. At the present, however, there is a lack of effective, automatic energy-management control practices and schemes available for application to small buildings. This is due, in large measure, to the absence of cost-effective integrated control equipment in the small-building marketplace. Furthermore, a general philosophy or strategy, for the application of equipment for total energy conservation in small commercial buildings has not yet evolved. Both technical and marketing issues related to the implementation of automation systems in small commercial buildings under 75,000 square feet gross area are explored. The functional requirements for small-building automation systems are identified and determination of system costs and energy savings potential are made. Market analyses identify cost and payback requirements as well as attitudes of potential equipment buyers in the small-building market. Schools, apartments, and offices, which together consume more than half the energy of the small-building market, are used as analysis models. The market and technical analyses are combined to formulate the potential marketplace for a small building AEMS in terms of building size, and building type. An AEMS concept is defined which embodies the necessary functional requirements within a framework of applied strategy to energy conservation in buildings.

Development of a Context Aware Virtual Smart Home Simulator  

E-Print Network (OSTI)

Context awareness is the most important research area in ubiquitous computing. In particular, for smart home, context awareness attempts to bring the best services to the home habitants. However, the implementation in the real environment is not easy and takes a long time from building the scratch. Thus, to support the implementation in the real smart home, it is necessary to demonstrate that thing can be done in the simulator in which context information can be created by virtual sensors instead of physical sensors. In this paper, we propose ISS, an Interactive Smart home Simulator system aiming at controlling and simulating the behavior of an intelligent house. The developed system aims to provide architects, designers a simulation and useful tool for understanding the interaction between environment, people and the impact of embedded and pervasive technology on in daily life. In this research, the smart house is considered as an environment made up of independent and distributed devices interacting to supp...

High availability using virtualization  

E-Print Network (OSTI)

High availability has always been one of the main problems for a data center. Till now high availability was achieved by host per host redundancy, a highly expensive method in terms of hardware and human costs. A new approach to the problem can be offered by virtualization. Using virtualization, it is possible to achieve a redundancy system for all the services running on a data center. This new approach to high availability allows to share the running virtual machines over the servers up and running, by exploiting the features of the virtualization layer: start, stop and move virtual machines between physical hosts. The system (3RC) is based on a finite state machine with hysteresis, providing the possibility to restart each virtual machine over any physical host, or reinstall it from scratch. A complete infrastructure has been developed to install operating system and middleware in a few minutes. To virtualize the main servers of a data center, a new procedure has been developed to migrate physical to virtu...

The Advantage of Highly Controlled Lighting for Offices and Commercial Buildings  

SciTech Connect

The paper presents results from pilot studies of new 'workstation-specific' luminaires that are designed to provide highly, efficient, customized lighting for open-office cubicles. Workstation specific luminaires have the following characteristics: (1) they provide separate, dimming control of the cubicle's 'ambient' and 'task' lighting components, (2) occupancy sensors and control photosensors are integrated into the fixture's design and operation, (3) luminaires can be networked using physical cabling, microcontrollers and a PC running control software. The energy savings, demand response capabilities and quality of light from the two WS luminaires were evaluated and compared to the performance of a static, low-ambient lighting system that is uncontrolled. Initial results from weeks of operation provide strong indication that WS luminaires can largely eliminate the unnecessary lighting of unoccupied cubicles while providing IESNA-required light levels when the cubicles are occupied. Because each cubicle's lighting is under occupant sensor control, the WS luminaires can capitalize on the fact cubicles are often unoccupied during normal working hours and reduce their energy use accordingly.

Building The last mile'  

SciTech Connect

Utilities may want to leverage the multibillion-dollar investment cable television is about to make. Virtually every utility has corporate objectives to focus more on the customer and change the way the customer is viewed. Utility supply strategy has been shifting away from building large, expensive power plants to making smaller investments with flexible options that can be adjusted to suit future conditions. This strategy is requisite to helping utilities keep and build their share of the market. One result is that utilities and regulators have adopted the concept of demand-side management (DSM) with enthusiasm. What's more, the last 10 years have brought new utility initiatives to explore customer value-oriented pricing structures that recognize the varying cost of production. These DSM opportunities and pricing initiatives require utilities to communicate with customers and help them manage their electricity use. New DSM programs that rely on communications technology include: (1) Providing real-time price signals for electricity-and eventually gas and water; (2) Implementing a direct- or shared-load control program for peak clipping or valley filling by interacting with properly equipped smart appliances; (3) Providing beyond-the-meter value-added services for residential customers, such as weather monitoring, video communications, home comfort automation, appliance monitoring and diagnostics, and energy efficiency tips; and (4) Obtaining detailed data on customers' electricity use patterns to develop new DSM programs. One action by the utility industry will determine whether this strategic vision is achieved: the establishment of a two-way, user-friendly, voice, data, and video communication path to the customer from the utility.

Virtual heliodon: Spatially augmented reality for architectural daylighting design  

E-Print Network (OSTI)

We present an application of interactive global illumination and spatially augmented reality to architectural daylight modeling that allows designers to explore alternative designs and new technologies for improving the sustainability of their buildings. Images of a model in the real world, captured by a camera above the scene, are processed to construct a virtual 3D model. To achieve interactive rendering rates, we use a hybrid rendering technique, leveraging radiosity to simulate the inter-reflectance between diffuse patches and shadow volumes to generate per-pixel direct illumination. The rendered images are then projected on the real model by four calibrated projectors to help users study the daylighting illumination. The virtual heliodon is a physical design environment in which multiple designers, a designer and a client, or a teacher and students can gather to experience animated visualizations of the natural illumination within a proposed design by controlling the time of day, season, and climate. Furthermore, participants may interactively redesign the geometry and materials of the space by manipulating physical design elements and see the updated lighting simulation.

Summer-heat-gain control in passive-solar-heated buildings: fixed horizontal overhangs  

DOE Green Energy (OSTI)

An aspect of passive cooling relates to cooling load reduction by the use of solar controls. When there is a substantial winter heating requirement, and when the winter heating needs are met in part by a passive solar heating system, then the potential aggravation of summer cooling loads by the heating system is an important design issue. A traditional solution is the use of a fixed, horizontal shading overhang. An approach to quantitative design rules for the sizing of a shading overhang to minimize total annual space conditioning energy needs is outlined.

Control of Greenhouse Gas Emissions by Optimal DER Technology Investment and Energy Management in Zero-Net-Energy Buildings  

Science Conference Proceedings (OSTI)

The U.S. Department of Energy has launched the commercial building initiative (CBI) in pursuit of its research goal of achieving zero-net-energy commercial buildings (ZNEB), i.e. ones that produce as much energy as they use. Its objective is to make these buildings marketable by 2025 such that they minimize their energy use through cutting-edge, energy-efficiency technologies and meet their remaining energy needs through on-site renewable energy generation. This paper examines how such buildings may be implemented within the context of a cost- or CO2-minimizing microgrid that is able to adopt and operate various technologies: photovoltaic modules (PV) and other on-site generation, heat exchangers, solar thermal collectors, absorption chillers, and passive/demand-response technologies. A mixed-integer linear program (MILP) that has a multi-criteria objective function is used. The objective is minimization of a weighted average of the building's annual energy costs and CO2 emissions. The MILP's constraints ensure energy balance and capacity limits. In addition, constraining the building's energy consumed to equal its energy exports enables us to explore how energy sales and demand-response measures may enable compliance with the ZNEB objective. Using a commercial test site in northernCalifornia with existing tariff rates and technology data, we find that a ZNEB requires ample PV capacity installed to ensure electricity sales during the day. This is complemented by investment in energy-efficient combined heat and power (CHP) equipment, while occasional demand response shaves energy consumption. A large amount of storage is also adopted, which may be impractical. Nevertheless, it shows the nature of the solutions and costs necessary to achieve a ZNEB. Additionally, the ZNEB approach does not necessary lead to zero-carbon (ZC) buildings as is frequently argued. We also show a multi-objective frontier for the CA example, whichallows us to estimate the needed technologies and costs for achieving a ZC building or microgrid.

Virtual Environment and  

E-Print Network (OSTI)

The levels of immersion and presence felt by users in a Virtual Environment (VE) are very important factors that dictate the quality of the Virtual Reality (VR) experience. Sensori-motor systems, both hardware and software, are the components of a VR system that contribute to generate the VEs and to create the feeling of being there. This paper reviews the different visualization hardware/software components that are at the heart of a VR system and provides means for assessing their performance in the context of various applications. Because of its historical and functional importance in the field of VR, visualization hardware is reviewed first (HMDs, VRDs, stereo glasses, CRT, LCD monitors and Plasma displays...). Then, a list of the most important insights, which should be addressed when designing and assembling a VR system, are discussed. Finally, visualization software is covered in the context of the available hardware components.

Virtual Human Problem Solving Environments  

SciTech Connect

Abstract. Interest in complex integrated digital or virtual human modeling has seen a significant increase over the last decade. Coincident with that increased interest, Oak Ridge National Laboratory (ORNL) initiated the development of a human simulation tool, the Virtual Human. The Virtual Human includes a problem-solving environment (PSE) for implementing the integration of physiological models in different programming languages and connecting physiological function to anatomy. The Virtual Human PSE (VHPSE) provides the computational framework with which to develop the concept of a "Virtual Human." Supporting the framework is a data definition for modeling parameters, PhysioML, a Virtual Human Database (VHDB), and a Web-based graphical user interface (GUI) developed using Java. Following description of the VHPSE, we discuss four example implementations of models within the framework. Further expansion of a human modeling environment was carried out in the Defense Advanced Research Projects Agency Virtual Soldier Project. SCIRun served as the Virtual Soldier problem solving environment (VSPSE). We review and compare specific developments in these projects that have significant potential for the future of Virtual Human modeling and simulation. We conclude with an evaluation of areas of future work that will provide important extensions to the VHPSE and VSPSE and make possible a fully-integrated environment for human anatomical and physiological modeling: the Virtual Human.

Experiences on the Implementation of the 'Energy Balance' Methodology as a Data Quality Control Tool: Application to the Building Energy Consumption of a Large University Campus  

E-Print Network (OSTI)

As the energy costs have been increasing the more energy efficient measures have been promoted in the buildings sector, the reliability of energy consumption data has been attracting significant attention. For example, the reliability of the determination of energy savings depends on that of the energy consumption data, which has to be verified before and after any efficiency measure is applied. From other perspective, verifying energy use data on a regular basis would allow the engineers to identify and assess commissioning opportunities confidently. This paper presents the application of an innovative data screening methodology as a data quality control tool for energy consumption data. The methodology has been applied to a large university campus where the monthly energy consumption, of approximately 100 buildings, must be verified. One of the main responsibilities of the Energy Management Office of the university is to provide monthly utility consumption and cost information to accounting for utility billing of individual buildings. The methodology, which is based on the first law of thermodynamics, or energy conservation, has proved to be an effective data quality screening method for verification of metering sensors when heating, cooling and electricity consumption are separately metered in a building. The methodology is anticipated to be suitable for automated application. In some cases, the methodology could also help to rehabilitate energy use data.

Study on Control Performance of HVAC System or Interior Zone and Perimeter Zone in Office Building; Estimation of Optimal PI Tuning in Cooling Operation  

E-Print Network (OSTI)

In office buildings there are generally two HVAC systems installed, one in the perimeter zone (PZ) and one in the interior zone (IZ), and the temperatures of each zone are independently controlled. In the present paper, in order to the solve problem of not being able to satisfy the requirements of room temperature control during the cooling period in summer, an optimal PID parameter (O-PI) is selected through simulation of its two feedback control systems with mutual influence using the models identified with the experimental data. The step response characteristics of the system with optimal parameters compared to those with the parameters selected by the Ziegler-Nichols Method (ZNM-PI) that are generally used for PID parameter tuning on site. The result shows O-PI improved control performance, and the difference between O-PI and ZNM-PI can be used to readjust ZNM-PI selected on site.

Virtual Optical Comparator  

SciTech Connect

The Virtual Optical Comparator, VOC, was conceived as a result of the limitations of conventional optical comparators and vision systems. Piece part designs for mechanisms have started to include precision features on the face of parts that must be viewed using a reflected image rather than a profile shadow. The VOC concept uses a computer generated overlay and a digital camera to measure features on a video screen. The advantage of this system is superior edge detection compared to traditional systems. No vinyl charts are procured or inspected. The part size and expensive fixtures are no longer a concern because of the range of the X-Y table of the Virtual Optical Comparator. Product redesigns require only changes to the CAD image overlays; new vinyl charts are not required. The inspection process is more ergonomic by allowing the operator to view the part sitting at a desk rather than standing over a 30 inch screen. The procurement cost for the VOC will be less than a traditional comparator with a much smaller footprint with less maintenance and energy requirements.

In this paper we report about our attempts to rebuild a historical building, `Huys Hengelo', its interior, a farm built next to it and other parts of its environment (including a draw-bridge and a gate) using the Virtual Reality Modeling Language (VRML). This castle building played an important role in the history of its region. The main issues we deal with in this paper are: the unreliability of available sources - forcing us to show alternatives rather than `the building as it was', the possibility to allow users to make changes and to experiment with different geographies, animations showing how parts of the wooden buildings were constructed during that time, the interface with the user and, as the project started as a student project on the request of some local historians and architects, some of our experiences with the co-operation between them and computer science students and researchers.

Modelling Complex Fenestration Systems using physical and virtual models  

Science Conference Proceedings (OSTI)

Physical or virtual models are commonly used to visualize the conceptual ideas of architects, lighting designers and researchers; they are also employed to assess the daylighting performance of buildings, particularly in cases where Complex Fenestration Systems (CFS) are considered. Recent studies have however revealed a general tendency of physical models to over-estimate this performance, compared to those of real buildings; these discrepancies can be attributed to several reasons. In order to identify the main error sources, a series of comparisons in-between a real building (a single office room within a test module) and the corresponding physical and virtual models was undertaken. The physical model was placed in outdoor conditions, which were strictly identical to those of the real building, as well as underneath a scanning sky simulator. The virtual model simulations were carried out by way of the Radiance program using the GenSky function; an alternative evaluation method, named Partial Daylight Factor method (PDF method), was also employed with the physical model together with sky luminance distributions acquired by a digital sky scanner during the monitoring of the real building. The overall daylighting performance of physical and virtual models were assessed and compared. The causes of discrepancies between the daylighting performance of the real building and the models were analysed. The main identified sources of errors are the reproduction of building details, the CFS modelling and the mocking-up of the geometrical and photometrical properties. To study the impact of these errors on daylighting performance assessment, computer simulation models created using the Radiance program were also used to carry out a sensitivity analysis of modelling errors. The study of the models showed that large discrepancies can occur in daylighting performance assessment. In case of improper mocking-up of the glazing for instance, relative divergences of 25-40% can be found in different room locations, suggesting that more light is entering than actually monitored in the real building. All these discrepancies can however be reduced by making an effort to carefully mock up the geometry and photometry of the real building. A synthesis is presented in this article which can be used as guidelines for daylighting designers to avoid or estimate errors during CFS daylighting performance assessment. (author)

Real-Time Forcast Model Analysis of Daily Average Building Load for a Thermal Storage System Control  

E-Print Network (OSTI)

Thermal storage systems were originally designed to shift the on-peak cooling production to off-peak cooling production to reduce the on-peak demand. Based on the current electricity charging structure, the reduction of both on-peak and off-peak demands is becoming an exceedingly important issue. Reduction of both on-peak and off-peak demands can also extend the life span and defer or eliminate the replacement of power transformers due to potential shortage of building power capacity with anticipated equipment load increases. The next day daily average electricity demand is a critical set point to operate chillers and associated pumps at the appropriate time. For this paper, a mathematic analysis was conducted for annual daily average cooling of a building and three real-time building load forecasting models were developed. They are first-order autogressive model, random walk model and linear regression model. Finally, the comparison of results show the random walk model provides the best forecast.

Primitive Virtual Negative Charge  

E-Print Network (OSTI)

Physical fields, such as gravity and electromagnetic field, are interpreted as results from rearrangement of vacuum particles to get the equilibrium of net charge density and net mass density in 4-dimensional complex space. Then, both fields should interact to each other in that physical interaction is considered as a field-to-field interaction. Hence, Mass-Charge interaction is introduced with primitive-virtual negative charge defined for the mass. With the concept of Mass-Charge interaction electric equilibrium of the earth is discussed, especially about the electric field and magnetic field of the earth. For unsettled phenomena related with the earth's gravity, such as antigravity phenomenon, gravity anomalies during the solar eclipses, the connection between geomagnetic storms and earthquakes, etc., possible explanations are discussed.

Virtual Appliances for Deploying and Maintaining Software  

E-Print Network (OSTI)

This paper attempts to address the complexity of system administration by making the labor of applying software updates independent of the number of computers on which the software is run. Complete networks of machines are packaged up as data; we refer to them as virtual appliances. The publisher of an appliance controls the software installed on the appliance, from the operating system to the applications, and is responsible for keeping the appliance up to date. These appliances can be configured by users to fit their needs; the configuration is captured such that it can be reapplied automatically when the appliance's software is updated. We have developed a compute utility, called the Collective, which assigns virtual appliances to hardware dynamically and automatically. By keeping software up to date, our approach prevents security break-ins due to fixed vulnerabilities.

Model Code for the Control of Residential HVAC Distribution System Leakage and HVAC-Induced Building Leakage  

E-Print Network (OSTI)

Modifications to local and state codes are seen as an appropriate strategy for the prevention of residential air distribution system leakage and its impacts. A model code element has been developed to assist this strategy. Recent field studies of Florida residences by Cummings, Tooley and Moyer have revealed a mean leakage of 11 percent for the air distribution systems of central, fan-force heating and air conditioning systems. Such leakage may cause an estimated 20 percent increase in energy consumption for air conditioning, as well as a 50 percent increase in peak cooling load and an 80 percent increase in peak heating load. In addition, building air leakage may be expected to be several times greater when duct leakage is present or when avenues of air egress from closeable rooms are absent. The model duct construction element presented here contains all of the standards, definitions and code language needed to replace the current duct construction element of the local or state code. The content of this paper was used as a principal source for language adopted for the 1991 Florida Energy Efficiency Code For Building Construction. Addressed are the most appropriate standards required for the closure and sealing of metal duct, rigid fibrous glass duct, and nonmetallic flexible duct. Also addressed are (1) detailed requirements for the sealing of mechanical closets when they function as plenum chambers, (2) detailed requirements for the sealing of enclosed support platforms or air handlers and furnaces when they function as return duct, (3) detailed requirements for the sealing of uninhabitable cavities of the building structure, when they function as duct, and (4) detailed requirements for the egress of air from enclosed rooms which receive supply air. Where necessary, commentary is provided to explain the options available for implementing the model code provision as well as its ramifications. All provisions of this model code are compatible with the requirements, standards and guidelines contained in related documents published by the following organizations: the Southern Building Code Congress International, Inc., the Sheet Metal and Air Conditioning Contractors National Association, the American Society of Heating, Refrigerating and Air conditioning Engineers, Underwriters Laboratories, Inc., the Air Conditioning Contractors Of America, the Thermal Insulation Manufacturers Association, the National Fire Protection Association, and the Gypsum Association.

Usage of Friction-damped Braced Frames for Seismic Vibration Control  

E-Print Network (OSTI)

This study presents the results of experimental work that examines the functionality of friction-damped braced frames during seismic events. The simplicity and efficacy of this friction device as a means of passive vibration control suggest that it may have notable implications in the field of structural engineering. Little scholarship has been devoted to this issue in recent years, and further research to advance our understanding of its possible implementations is necessary. To measure the functionality of this type of frame, this study first examines and compares virtual models of a building modeling the effect of friction damping versus that same building without such damping. It then corroborates these findings by presenting the results of physical experimentation on a scale model of the building, both with and without damping. The validation of the virtual models by the physical model provides credence to the usage of friction-damped braced frames as a seismic energy dissipating system.

Developing a next-generation community college curriculum forenergy-efficient high-performance building operations  

Science Conference Proceedings (OSTI)

The challenges of increased technological demands in today's workplace require virtually all workers to develop higher-order cognitive skills including problem solving and systems thinking in order to be productive. Such ''habits of mind'' are viewed as particularly critical for success in the information-based workplace, which values reduced hierarchy, greater worker independence, teamwork, communications skills, non-routine problem solving, and understanding of complex systems. The need is particularly compelling in the buildings arena. To scope the problem, this paper presents the results of interviews and focus groups--conducted by Oakland California's Peralta Community College District and Lawrence Berkeley National Laboratory--in which approximately 50 industry stakeholders discussed contemporary needs for building operator education at the community college level. Numerous gaps were identified between the education today received by building operators and technicians and current workplace needs. The participants concurred that many of the problems seen today in achieving and maintaining energy savings in buildings can be traced to inadequacies in building operation and lack of awareness and knowledge about how existing systems are to be used, monitored, and maintained. Participants and others we interviewed affirmed that while these issues are addressed in various graduate-level and continuing education programs, they are virtually absent at the community college level. Based on that assessment of industry needs, we present a new curriculum and innovative simulation-based learning tool to provide technicians with skills necessary to commission and operate high-performance buildings, with particular emphasis on energy efficiency and indoor environmental quality in the context of HVAC&R equipment and control systems.

Energy management for hypervisor-based virtual machines  

E-Print Network (OSTI)

Current approaches to power management are based on operating systems with full knowledge of and full control over the underlying hardware; the distributed nature of multi-layered virtual machine environments renders such approaches insufficient. In this paper, we present a novel framework for energy management in modular, multi-layered operating system structures. The framework provides a unified model to partition and distribute energy, and mechanisms for energy-aware resource accounting and allocation. As a key property, the framework explicitly takes the recursive energy consumption into account, which is spent, e.g., in the virtualization layer or subsequent driver components. Our prototypical implementation targets hypervisor-based virtual machine systems and comprises two components: a host-level subsystem, which controls machine-wide energy constraints and enforces them among all guest OSes and service components, and, complementary, an energy-aware guest operating system, capable of fine-grained applicationspecific energy management. Guest level energy management thereby relies on effective virtualization of physical energy effects provided by the virtual machine monitor. Experiments with CPU and disk devices and an external data acquisition system demonstrate that our framework accurately controls and stipulates the power consumption of individual hardware devices, both for energy-aware and energyunaware guest operating systems. 1

Building America  

Science Conference Proceedings (OSTI)

Builders generally use a 'spec and purchase' business management system (BMS) when implementing energy efficiency. A BMS is the overall operational and organizational systems and strategies that a builder uses to set up and run its company. This type of BMS treats building performance as a simple technology swap (e.g. a tank water heater to a tankless water heater) and typically compartmentalizes energy efficiency within one or two groups in the organization (e.g. purchasing and construction). While certain tools, such as details, checklists, and scopes of work, can assist builders in managing the quality of the construction of higher performance homes, they do nothing to address the underlying operational strategies and issues related to change management that builders face when they make high performance homes a core part of their mission. To achieve the systems integration necessary for attaining 40% + levels of energy efficiency, while capturing the cost tradeoffs, builders must use a 'systems approach' BMS, rather than a 'spec and purchase' BMS. The following attributes are inherent in a systems approach BMS; they are also generally seen in quality management systems (QMS), such as the National Housing Quality Certification program: Cultural and corporate alignment, Clear intent for quality and performance, Increased collaboration across internal and external teams, Better communication practices and systems, Disciplined approach to quality control, Measurement and verification of performance, Continuous feedback and improvement, and Whole house integrated design and specification.

Integrated Building Management System (IBMS)  

SciTech Connect

This project provides a combination of software and services that more easily and cost-effectively help to achieve optimized building performance and energy efficiency. Featuring an open-platform, cloud- hosted application suite and an intuitive user experience, this solution simplifies a traditionally very complex process by collecting data from disparate building systems and creating a single, integrated view of building and system performance. The Fault Detection and Diagnostics algorithms developed within the IBMS have been designed and tested as an integrated component of the control algorithms running the equipment being monitored. The algorithms identify the normal control behaviors of the equipment without interfering with the equipment control sequences. The algorithms also work without interfering with any cooperative control sequences operating between different pieces of equipment or building systems. In this manner the FDD algorithms create an integrated building management system.

E-Print Network (OSTI)

In the development of virtual communities, a new phenomenon of virtual money is observed and presented high importance to both e-commerce and e-society fields. This paper, as a pioneer research, has attempted to make a phenomenal analysis on the existing virtual money systems. By the analysis, this paper has defined what virtual money is, what its general models are, and how its existing systems work. By the analysis, the features of existing virtual money systems are abstracted and their problems are summarized. Driven by the motivation of utilizing and improving the existing virtual money systems, this paper has outlined a novel generic virtual money system model called Common Money (CONEY) to resolve the problems that bother the existing virtual money systems. Finally, further interesting issues for future research are given. 1.

Transportation planning: A virtual reality  

SciTech Connect

An important factor in the development of any base technology is generating it in such a way that these technologies will continue to be useful through systems upgrades and implementation philosophy metamorphoses. Base technologies of traffic engineering including transportation modeling, traffic impact forecasting, traffic operation management, emergency situation routing and re-routing, and signal systems optimization should all be designed with the future in mind. Advanced Traffic Engineering topics, such as Intelligent Vehicle Highway Systems, are designed with advanced engineering concepts such as rules-based design and artificial intelligence. All aspects of development of base technologies must include Total Quality Engineering as the primary factor in order to succeed. This philosophy for development of base technologies for the County of Los Alamos is being developed leveraging the resources of the Center for Advanced Engineering Technology (CAET) at the Los Alamos National Laboratory. The mission of the CAET is to develop next-generation engineering technology that supports the Los Alamos National Laboratory`s mission and to transfer that technology to industry and academia. The CAET`s goal is to promote industrial, academic, and government interactions in diverse areas of engineering technology, such as, design, analysis, manufacturing, virtual enterprise, robotics, telepresence, rapid prototyping, and virtual environment technology. The Center is expanding, enhancing, and increasing core competencies at the Los Alamos National Laboratory. The CAET has three major thrust areas: development of base technologies, virtual environment technology applications, and educational outreach and training. Virtual environment technology immerses a user in a nonexistent or augmented environment for research or training purposes. Virtual environment technology illustrates the axiom, ``The best way to learn is by doing.``

Testing the effectiveness of mobile home weatherization measures in a controlled environment: The SERI CMFERT (Collaborative Manufactured Buildings Facility for Energy Research and Training) Project  

SciTech Connect

For several years the Solar Energy Research Institute has been testing the effectiveness of mobile home weatherization measures, with the support of the US DOE Office of State and Local Assistance Programs Weatherization Assistance Program, the DOE Office of Buildings and Community Systems, the seven states within the federal Weatherization Region 7, the Colorado Division of Housing, and the DOE Denver Support Office. During the winter of 1988--89, several weatherization measures were thermally tested on three mobile homes under controlled conditions inside a large environmental enclosure. The effects of each weatherization measure on conduction losses, infiltration losses, and combined furnace and duct-delivered heat efficiency were monitored. The retrofit options included air sealing, duct repair, furnace tune-up, interior storm panels, floor insulation, and roof insulation. The study demonstrated that cost-effective heating energy savings of about 20% to 50% are possible if weatherization techniques adapted to the special construction details in mobile homes are applied. 24 refs., 18 figs., 9 tabs.

Types of Lighting in Commercial Buildings - Changes  

U.S. Energy Information Administration (EIA) Indexed Site

Changes in Lighting Changes in Lighting The percentage of commercial buildings with lighting was unchanged between 1995 and 2003; however, three lighting types did show change in usage. Compact fluorescent lamps and halogen lamps showed a significant increase between 1995 and 2003 while the use of incandescent lights declined. The lighting questions in the 1995, 1999, and 2003 CBECS questionnaires were virtually identical which facilitates comparison across survey years. The use of compact fluorescent lamps more than doubled, from just under 10 percent of lit buildings to more than 20 percent (Figure 17 and Table 5). The use of halogen lamps nearly doubled, from 7 percent to 13 percent of lit buildings. Use of incandescent lights was the only lighting type to decline; their use dropped from 59 percent to just over one-half of lit buildings.
