Modelling and simulation of elements for solar heating and daylighting  

SciTech Connect

Through the development of highly efficient transparent insulation materials (TIM), new opportunities are appearing in the field of daylighting and passive solar space heating. The simulation program WANDSIM, developed at the Fraunhofer-Institut fuer Solare Energiesysteme (ISE), models the dynamic performance of three important elements for daylighting and passive solar space heating; window glazing; transparently insulated masonry; transparently insulated glass wall. Selected simulation results of each type are represented and compared under thermal and daylighting aspects. The advantages of the transparently insulated glass wall, a new combined passive space heating and daylighting system, in economy and comfort are verified.

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.

Light-scattering properties of a woven shade-screen material used for daylighting and solar heat-gain control  

Science Conference Proceedings (OSTI)

Shade-screens are widely used in commercial buildings as a way to limit the amount of direct sunlight that can disturb people in the building. The shade screens also reduce the solar heat-gain through glazing the system. Modern energy and daylighting analysis software such as EnergyPlus and Radiance require complete scattering properties of the scattering materials in the system. In this paper a shade screen used in the LBNL daylighting testbed is characterized using a photogoniometer and a normal angle of incidence integrating sphere. The data is used to create a complete bi-directional scattering distribution function (BSDF) that can be used in simulation programs. The resulting BSDF is compared to a model BADFs, both directly and by calculating the solar heat-gain coefficient for a dual pane system using Window 6.

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.

Particular attention is given to daylighting while designing a building when the aim is to maximize visual comfort or to reduce energy use. Energy savings can be achieved either from the reduced use of artificial (electric) lighting or from passive solar heating or cooling. Artificial lighting energy use can be reduced by simply installing fewer electric lights because daylight is present, or by dimming/switching electric lights automatically in response to the presence of daylight, a

Capturing the Daylight Dividend  

Science Conference Proceedings (OSTI)

Capturing the Daylight Dividend conducted activities to build market demand for daylight as a means of improving indoor environmental quality, overcoming technological barriers to effective daylighting, and informing and assisting state and regional market transformation and resource acquisition program implementation efforts. The program clarified the benefits of daylight by examining whole building systems energy interactions between windows, lighting, heating, and air conditioning in daylit buildings, and daylighting's effect on the human circadian system and productivity. The project undertook work to advance photosensors, dimming systems, and ballasts, and provided technical training in specifying and operating daylighting controls in buildings. Future daylighting work is recommended in metric development, technology development, testing, training, education, and outreach.

Daylighting Quality Daylighting Quality With a small building footprint and a relatively large vertical surface area, the CUSD house has the unique opportunity to supply almost all of its lighting with daylight. Keeping this in mind, we have created two large apertures, one on the south side of the building and one on the north side of the building. The southern aperture is a tri-fold glass door, opening to the living room on the west side of the house. This fenestration provides ambient light and some heat to the space during the day. Occupants can take advantage of this daylight as they go to and return from work, prepare meals, and relax in the living area. Concrete pavers (thermal mass) are placed inside and outside of the southern aperture, bridging the threshold between interior and exterior spaces. The

Daylight in Manhattan  

SciTech Connect

Zoning regulations concerned with daylighting in New York City are reviewed extensively going back to the 1916 regulation. Historical developments up to the newly proposed set of zoning regulations for midtown Manhattan are discussed. The importance of the Manhattan regulations, which often serve as a model for other USA cities, are stressed. The daylight performance test, designed to quantify the amount of natural light that will reach the street after a proposed project is constructed, is described. To gain acceptance a new building would have to score at least 85 points (out of 100) on criteria based on daylighting, street wall height, street wall length, and reflectivity. Of these, daylighting is the most important. A modified and simplified two-tiered proposal has been issued with minor changes in scoring the four criteria given above. (MJJ)

Daylighting has good potential for application in tropical climates. It can help save electric energy as well as reduce the daytime power demand substantially. It can bring another dimension of energy efficiency in addition to efficient lighting technology, as well as aesthetic value. Its integration with continuous-dimming electric lighting is found to be acceptable. However, fundamental research as well as daylighting application technology are required to realize the potential.

Neural daylight control system  

E-Print Network (OSTI)

The paper describes the design, the implementation of a neural controller used in an automatic daylight control system. The automatic lighting control system (ALCS) attempt to maintain constant the illuminance at the desired level on working plane even if the daylight contribution is variable. Therefore, the daylight will represent the perturbation signal for the ALCS. The mathematical model of process is unknown. The applied structure of control need the inverse model of process. For this purpose it was used other artificial neural network (ANN) which identify the inverse model of process in an on-line manner. In fact, this ANN identify the inverse model of process + the perturbation signal. In this way the learning signal for neural controller has a better accuracy for the present application.

Advanced optical daylighting systems: light shelves and light pipes  

SciTech Connect

We present two perimeter daylighting systems that passively redirect beam sunlight further from the window wall using special optical films, an optimized geometry, and a small glazing aperture. The objectives of these systems are (1) to increase daylight illuminance levels at 4.6-9.1 m (15-30 ft) from the window aperture with minimum solar heat gains and (2) to improve the uniformity of the daylighting luminance gradient across the room under variable solar conditions throughout the year. The designs were developed through a series of computer-assisted ray-tracing studies, laser visualization techniques, and photometric measurements and observations using physical scale models. Bi-directional illuminance measurements in combination with analytical routines were then used to simulate daylight performance for any solar position, and were incorporated into the DOE-2.1E building energy analysis computer program to evaluate energy savings. Results show increased daylight levels and an improved luminance gradient throughout the year compared to conventional daylighting systems.

Design and Evaluation of Daylighting Applications of Holographic Glazings

Design and Evaluation of Daylighting Applications of Holographic Glazings Design and Evaluation of Daylighting Applications of Holographic Glazings Title Design and Evaluation of Daylighting Applications of Holographic Glazings Publication Type Report LBNL Report Number LBNL-44167 Year of Publication 1996 Authors Papamichael, Konstantinos M., Charles K. Ehrlich, and Gregory J. Ward Call Number LBNL-44167 Abstract When combined with appropriate electric lighting dimming controls, the use of daylight for ambient and task illumination can significantly reduce energy requirements in commercial buildings. While skylights can effectively illuminate any part of one-story buildings, conventional side windows can illuminate only a 15 ft - 20 ft (4.6 m - 6.1 m) depth of the building perimeter. Even so, the overall efficacy of daylight is limited, because side windows produce uneven distributions of daylight. Achieving adequate illumination at distances further away from the window results in excessive illumination near the window, which increases cooling loads from the associated solar heat gain. As a result, the use of larger apertures and/or higher transmittance glazings, to introduce daylight deeper than 15 ft - 20 ft (4.6 m - 6.1 m), may prove ineffective with respect to saving energy, because cooling load penalties may exceed the electric lighting savings.

Arasteh Conference Name 10th Passive Solar Conference Date Published 10/1985 Conference Location Raleigh, NC Call Number LBL-20080 Abstract The use of daylighting to supplant electric light in office buildings offers substantial energy savings and peak electrical demand reductions. The benefits from electric lighting reductions can, however, be easily offset by increased cooling loads if solar gains are not controlled.sThe use of advanced glazing materials having optical switching propertiesscan facilitate solar control and, with proper design, maximize energy and cost benefits. The potential net annual performance of these materials, based on simulation studies using DOE-2.1C, are discussed insthis paper. Actively and passively controlled response functions aresanalyzed for the cooling-load-dominated climate of Lake Charles. The effects of advanced materials on net annual energy consumption, peak electrical demand, and chiller size are compared with those of conventional materials. The results demonstrate the importance of operable solar control to achieve energy-effective daylighting design. Advanced optical materials that provide the necessary level of control are shown to minimize peak electrical demand and electricity consumption.

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.

Automated roller shades Automated roller shades 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 Automated roller shades Automated roller shades manage daylight, solar heat gains, view, glare, privacy, and building appearance through changes in shade height. A roller shade consists of a fabric wrapped around a horizontal tube, which contains a tubular motor. The tubular motor rotates when ac- or dc- power is applied to it causing modulation in shade height. The control system can be designed to optimize numerous variables, the most common being control of direct sun. In this application, the shades were controlled to five preset heights that aligned with the architectural features of the façade - i.e., the vision portion of the window wall - so that direct sun penetrated no more than a specified distance from the window wall. The Times Company also requested that the shades control window glare, yet maximize the opportunity for view and daylight admission. Unnecessary up/down movement of the shade was to be minimized. Fabric choices (openness of the weave, color of the fabric facing toward the interior and exterior) were additional considerations in terms of appearance as well as visual comfort and daylighting benefits.

Daylight, glazing, and building energy minimization  

SciTech Connect

This paper examines the effects of glazing on thermal loads. Annual heating, cooling, and lighting loads are reported for a window office in a Houston building in which five types of glass were simulated. The glass parameters are U-value, shading coeffient, visible band transmittance, and inside reflectance; therefore, a change in glass directly affected the solar heat gain. Once again, it was assumed that the artificial lights were continuously adjustable, that is, the lights provide the difference between the illumination required (user specified) and that provided by daylight.

The New York Times headquarters daylighting mockup: Monitoredperformance of the daylighting control system  

SciTech Connect

A nine-month monitored field study of the performance of automated roller shades and daylighting controls was conducted in a 401 m{sup 2} unoccupied, furnished daylighting mockup. The mockup mimicked the southwest corner of a new 110 km{sub 2} commercial building in New York, New York, where The New York Times will be the major tenant. This paper focuses on evaluating the performance of two daylighting control systems installed in separate areas of an open plan office with 1.2-m high workstation partitions: (1) Area A had 0-10 V dimmable ballasts with an open-loop proportional control system and an automated shade controlled to reduce window glare and increase daylight, and (2) Area B had digital addressable lighting interface (DALI) ballasts with a closed-loop integral reset control system and an automated shade controlled to block direct sun. Daylighting control system performance and lighting energy use were monitored. The daylighting control systems demonstrated very reliable performance after they were commissioned properly. Work plane illuminance levels were maintained above 90% of the maximum fluorescent illuminance level for 99.9{+-}0.5% and 97.9{+-}6.1% of the day on average over the monitored period, respectively, in Areas A and B. Daily lighting energy use savings were significant in both Areas over the equinox-to-equinox period compared to a non-daylit reference case. At 3.35 m from the window, 30% average savings were achieved with a sidelit west-facing condition in Area A while 50-60% were achieved with a bilateral daylit south-facing condition in Area B. At 4.57-9.14 m from the window, 5-10% and 25-40% savings were achieved in Areas A and B, respectively. Average savings for the 7-m deep dimming zone were 20-23% and 52-59% for Areas A and B, respectively, depending on the lighting schedule. The large savings and good reliability can be attributed to the automatic management of the interior shades. The DALI-based system exhibited faulty behavior that remains unexplained, but operational errors are expected to be resolved as DALI products reach full maturity. The building owner received very competitive bids ($30-75 US/DALI ballast) and was able to justify use of the daylighting control system based on operational cost savings and increased amenity. Additional energy savings due to reduced solar and lighting heat gains were not quantified but will add to the total operational cost savings.

Trichromatic Model of Daylight Variation  

E-Print Network (OSTI)

Visual recognition of colors in outdoor imagery is a difficult task in artificial vision, chiefly because of natural chromatic variation. To accurately predict an object's color, it is necessary to have an accurate model of daylight as a function of spatial, temporal and weather conditions, as well as the object's surface reflectance parameters, and all relevant camera parameters. Preliminary studies indicate that in a scenario involving outdoor robotic vehicles, such color prediction (and consequently, recognition) may be achieved, given reasonably accurate models of all of the above. This paper addresses the first link in the chain of models: building a usable model of daylight. Studies done in the sixties under the International Commission for Illumination Colorometry Committee (ICI/ CIE) to model the shift in natural illumination resulted in fairly accurate models which are still valid, and used as a standard of illumination by daylight. However, these studies are rarely used in ou...

This paper focuses on evaluating the performance of two daylighting control systems installed in separate areas of an open plan office with 1.2-m high workstation partitions: 1) Area A had 0-10 V dimmable ballasts with an open-loop proportional control system and an automated shade controlled to reduce window glare and increase daylight, and 2) Area B had digital addressable lighting interface (DALI) ballasts with a closed-loop integral reset control system and an automated shade controlled to block direct sun. Daylighting control system performance and lighting energy use were monitored. The daylighting control systems demonstrated very reliable performance after they were commissioned properly. Work plane illuminance levels were maintained above 90% of the maximum fluorescent illuminance level for 99.9+/-0.5% and 97.9+/-6.1% of the day on average over the monitored period, respectively, in Areas A and B. Daily lighting energy use savings were significant in both Areas over the equinox-to-equinox period compared to a non-daylit reference case. At 3.35 m from the window, 30% average savings were achieved with a sidelit west-facing condition in Area A while 50-60% were achieved with a bilateral daylit south-facing condition in Area B. At 4.57-9.14 m from the window, 5-10% and 25-40% savings were achieved in Areas A and B, respectively. Average savings for the 7-m deep dimming zone were 20-23% and 52-59% for Areas A and B, respectively, depending on the lighting schedule. The large savings and good reliability can be attributed to the automatic management of the interior shades. The DALI-based system exhibited faulty behavior that remains unexplained, but operational errors are expected to be resolved as DALI products reach full maturity. The building owner received very competitive bids ($30-75 US/DALI ballast) and was able to justify use of the daylighting control system based on operational cost savings and increased amenity. Additional energy savings due to reduced solar and lighting heat gains were not quantified but will add to the total operational cost savings.

Daylighting directory 6/1980  

SciTech Connect

A renewed interest in the energy conservation potential of daylighting has generated new research, applications and demonstration activities over the last few years. It is apparent that even those people actively working in the field are frequently not aware of all of the ongoing projects and activities. At the same time, the total national effort to utilize daylighting effectively in buildings on a broad scale is still very small, thus making it important that current activities are crossfertilized. The intent of this directory is to provide current listings of individuals and organizations that are actively engaged in daylighting work and related publications and upcoming events of interest. This directory was compiled from information contained in the survey response forms which were filled out and returned to us over the last few months. Responsibility for the accuracy and completeness of each survey form lies entirely with the respondents. The directory is composed of five parts: (1) Participant Survey Response: contains the survey response forms as submitted to us, listed alphabetically by responding organization; (2) Activity Index: lists individual respondents alphabetically, showing the daylighting activities each has checked. Allows the reader to quickly identify the individuals working in a specific area. Once an individual is identified, turn to the Individual Index to find the page numbers where that individual may be located in other areas of the directory; (3) Individual Index: lists individual respondents alphabetically; (4) Daylighting publications: lists the publications by each respondent (authors listed alphabetically); and (5) Notes of Interest: contains a variety of information on meetings, conferences, new projects and publications, etc. This material was collected from a variety of sources in addition to the survey respondents.

Integrating window pyranometer for beam daylighting measurements in scale-model buildings  

SciTech Connect

An experimental device has been developed to measure the total amount of solar radiation transmitted through glazed apertures in scale-model buildings. The device, an integrating window pyranometer (IWP), has two distinguishing characteristics: (1) it provides a measure of transmitted solar radiation integrated over a representative portion of the model glazing, accounting for nonuniform radiation distributions; and (2) it is spectrally independent. In applications to scale-model daylighting experiments, the IWP, together with photometric sensors mounted in the model, allows the direct measurement of the fraction of transmitted solar gains reaching the work plane as useful illumination, a convenient measure of the daylighting system performance. The IWP has been developed as part of an outdoor experimental facility to perform beam daylighting measurements in scale-model buildings. In this paper, the integrating window pyranometer is described; the results of calibration tests are presented and evaluated; the advantages and limitations of the device are discussed.

Daylight metrics and energy savings  

SciTech Connect

The drive towards sustainable, low-energy buildings has increased the need for simple, yet accurate methods to evaluate whether a daylit building meets minimum standards for energy and human comfort performance. Current metrics do not account for the temporal and spatial aspects of daylight, nor of occupants comfort or interventions. This paper reviews the historical basis of current compliance methods for achieving daylit buildings, proposes a technical basis for development of better metrics, and provides two case study examples to stimulate dialogue on how metrics can be applied in a practical, real-world context.

High-reliability computing for the smarter planet  

SciTech Connect

The geometric rate of improvement of transistor size and integrated circuit performance, known as Moore's Law, has been an engine of growth for our economy, enabling new products and services, creating new value and wealth, increasing safety, and removing menial tasks from our daily lives. Affordable, highly integrated components have enabled both life-saving technologies and rich entertainment applications. Anti-lock brakes, insulin monitors, and GPS-enabled emergency response systems save lives. Cell phones, internet appliances, virtual worlds, realistic video games, and mp3 players enrich our lives and connect us together. Over the past 40 years of silicon scaling, the increasing capabilities of inexpensive computation have transformed our society through automation and ubiquitous communications. In this paper, we will present the concept of the smarter planet, how reliability failures affect current systems, and methods that can be used to increase the reliable adoption of new automation in the future. We will illustrate these issues using a number of different electronic devices in a couple of different scenarios. Recently IBM has been presenting the idea of a 'smarter planet.' In smarter planet documents, IBM discusses increased computer automation of roadways, banking, healthcare, and infrastructure, as automation could create more efficient systems. A necessary component of the smarter planet concept is to ensure that these new systems have very high reliability. Even extremely rare reliability problems can easily escalate to problematic scenarios when implemented at very large scales. For life-critical systems, such as automobiles, infrastructure, medical implantables, and avionic systems, unmitigated failures could be dangerous. As more automation moves into these types of critical systems, reliability failures will need to be managed. As computer automation continues to increase in our society, the need for greater radiation reliability is necessary. Already critical infrastructure is failing too frequently. In this paper, we will introduce the Cross-Layer Reliability concept for designing more reliable computer systems.

Daylighting Prediction Software: Comparative Analysis and Application  

E-Print Network (OSTI)

Daylighting is a beneficial design strategy since it may provide energy savings and contribute to a more sustainable design. In recent studies, daylighting has also been shown to increase staff and student productivity and to decrease absenteeism. The consulting engineer is often faced with the dilemma of how to design a daylighted building. What tools are available to predict the amount of daylighting? What are the design limitations and parameters? How much time is required? How does the data compare to the real world? The purpose of this paper is to answer these questions and provide useful information for the design of daylighted areas with the assistance of software-based simulation. A survey was made of the available software programs for the calibrated modeling of light scattered in enclosed spaces. These software packages used algorithms based on either total radiosity (flux transfer) computations or physically accurate ray tracing. A summary of this survey along with the selection criteria used in selecting a software program are presented. Radiance, a reverse ray tracing method software package, was chosen for use in the simulations. An existing school was modeled with the Radiance software and predictions of daylighting contributions were compared with actual data taken at the site location. The use of daylighting also requires a highly specialized lighting system. This system incorporates the use of controllable ballasts and lighting sensors to maximize the daylighting contribution to the overall required illumination. Some design criteria for this system is also discussed.

Technology reviews: Daylighting optical systems  

SciTech Connect

We present a representative review of existing, emerging, and future technology options in each of five hardware and systems areas in envelope and lighting technologies: lighting systems, glazing systems, shading systems, daylighting optical systems, and dynamic curtain wall systems. The term technology is used here to describe any design choice for energy efficiency, ranging from individual components to more complex systems to general design strategies. The purpose of this task is to characterize the state of the art in envelope and lighting technologies in order to identify those with promise for advanced integrated systems, with an emphasis on California commercial buildings. For each technology category, the following activities have been attempted to the extent possible: Identify key performance characteristics and criteria for each technology. Determine the performance range of available technologies. Identify the most promising technologies and promising trends in technology advances. Examine market forces and market trends.Develop a continuously growing in-house database to be used throughout the project. A variety of information sources have been used in these technology characterizations, including miscellaneous periodicals, manufacturer catalogs and cut sheets, other research documents, and data from previous computer simulations. We include these different sources in order to best show the type and variety of data available, however publication here does not imply our guarantee of these data. Within each category, several broad classes are identified, and within each class we examine the generic individual technologies that fall into that class.

Effect of daylighting on energy consumption and daylight quality in an existing elementary school  

E-Print Network (OSTI)

This research investigates the effects of daylighting in an existing elementary school in College Station, Texas. The conclusions are generalizable to similar school designs in hot and humid climates. This study focuses on the trends observed in the building??s heating, cooling, and lighting energy consumption due to daylighting, and the overall effect on total energy consumption. Skylights with 1% to 10% glazing surface to floor area and clerestories from 2 ft to 8 ft glazing height were analyzed to formulate balanced daylighting designs that could provide for decreased electricity and gas energy consumption and increased daylight illuminance levels and energy cost savings. Classroom and Library areas inside the case study school building were analyzed using walk-throughs and daylight factor measurements to understand existing lighting conditions and the potential for daylighting. Physical scale models of the study spaces with and without daylighting alternatives were built for daylight factor and daylight penetration analysis. Computer simulation models were created for the base case and all proposed daylighting designs for building energy performance evaluation using the DOE-2 building energy simulation program. Daylight factors from the actual spaces, physical model measurements, and computer simulation outputs were studied for trendsin interior daylight illuminance levels. Annual energy consumption analyses were performed using DOE-2 and involved heating, cooling, and electrical energy use comparisons of all proposed designs with the base case. One design each from the skylight and clerestory cases, and an overall design based upon the performance criteria are proposed for the existing school building. The building energy analyses suggested that a considerable reduction in artificial lighting and total electricity use could be achieved through proper sizing of skylights and clerestories. Heating energy use stayed almost constant in all cases. Considering all different trends in energy use, all the proposed cases perform better than the base case in terms of total energy savings. The spaces analyzed constituted 15% of total school area, and projected savings would be much higher if daylighting could be applied to the entire school building.

Experimental Evaluation of Innovative Wall Daylighting Systems  

E-Print Network (OSTI)

Daylighting offers the potential to save electrical energy and reduce peak demand for lighting, the major consumer of energy in a variety of buildings. However, widespread adoption of daylighting techniques is hampered by the lack of both daylight resource information and simple, reliable methods of testing daylighting designs. To surmount these obstacles, facilities for collecting illuminance data and for testing small-scale and full-size models have been established. These are (1) an extensively instrumented resource measurement station, (2) a sun angle simulator for exploring the geometries of the sun and the building during the early stages of design, (3) a heliodon to allow detailed illuminance and luminance distribution measurements in scale models, and (4) a rotating test building for quantitative and qualitative assessments of full-scale components. The current research efforts have been using these facilities to seek ways of projecting light admitted through walls deep into interior spaces. Sidelighting systems are of interest because the wall is the only available source of daylight in many commercial buildings. Innovative static and dynamic reflector assemblies have been examined and proven effective. Compared with typical sidelighting designs, the systems examined in this study project light deeper and produce more uniform illuminance across the space.

Daylighting Application and Effectiveness in Industrial Facilities  

E-Print Network (OSTI)

Before the advent of practical mercury vapor and fluorescent lighting, the only available artificial lighting for industrial buildings was incandescent. The illumination of active industrial workspaces with incandescent lighting is difficult, so during the industrial revolution, architects utilized various daylighting strategies such as window walls, skylighting, monitors, etc. However, glazing technologies were primitive compared with our modern choices, When more efficient and effective artificial lighting became available, most older industrial buildings had their daylighting features boarded over. With modern glazing systems and sophisticated designs that minimize glare issues, daylighting for industrial buildings is making a strong comeback. Additionally, new controllable ballasts and automatic lighting controls make possible hybrid lighting systems that are able to provide optimal lighting under all environmental conditions. This paper will discuss how daylighting systems developed decades ago are being modernized to provide high quality, low-glare, uniform lighting. Premium glazing systems that limit heat losses and gain will be discussed. The importance of glare control in day-lit spaces, for worker safety and productivity, will be stressed, and a variety of passive and active strategies will be presented including: redirected beam daylighting; reflective light shelves; and movable baffles and louvers.

Utilizing Daylighting Controls in a Manufacturing Facility  

E-Print Network (OSTI)

Opportunities exist to reduce artificial lighting in manufacturing facilities which have skylights and/or fenestration that provide sufficient quantities of daylight to the work space. Using photometric sensors to measure the illuminance in the space, artificial lights can be automatically switched off during periods when sufficient daylight is available. Daylighting controls used in commercial buildings often use dimmable ballasts with fluorescent lights. Most fluorescent lighting used in manufacturing facilities use high output ballasts which are non-dimmable. The preferred method for reducing artificial lighting output is to switch the lamps off. For multi-lamp fixtures such as six-lamp Super T8s, ballast/lamp configurations are either 2-4 or 3-3, thus giving rise to various stages of lighting reduction. This paper examines these lighting control strategies for a 90,000 square foot manufacturing facility in Iowa. Using the EnergyPlus building energy simulation code, annual lighting energy savings associated with utilization of daylighting were computed for the building. Results showed that the 2- 4 switching control strategy provided better energy reduction opportunity compared to 3-3 switching control.

Evaluation of Lightshelf Daylighting Systems for Office Buildings in Hot Climates  

E-Print Network (OSTI)

This paper presents part of an on-going research project in the College of Architecture at Texas A&M University. This research investigates how lightshelf daylighting delivery systems can manipulate sunlight and daylight both in terms of their light and heat by shading view apertures below the shelf to reduce solar heat gain and glare and by reflecting light deep into the space through the daylight aperture above the shelf. It also investigates how to provide view with good interior lighting in terms of light levels, distribution, and glare. Evaluation of these systems are based on two different experiments. The first uses scale-models for daylighting evaluation. Methodology of the research is presented as well as results and evaluation for part of the first experiment. The second experiment will use computer program simulations for energy evaluation that include reducing lighting and cooling loads and shaving peak loads, especially, when used with selective low-e glazing for office buildings in hot climates.

Monitored Energy Performance of Electrochromic Windows Controlledfor Daylight and Visual Comfort  

SciTech Connect

A 20-month field study was conducted to measure the energy performance of south-facing large-area tungsten-oxide absorptive electrochromic (EC) windows with a broad switching range in a private office setting. The EC windows were controlled by a variety of means to bring in daylight while minimizing window glare. For some cases, a Venetian blind was coupled with the EC window to block direct sun. Some tests also involved dividing the EC window wall into zones where the upper EC zone was controlled to admit daylight while the lower zone was controlled to prevent glare yet permit view. If visual comfort requirements are addressed by EC control and Venetian blinds, a 2-zone EC window configuration provided average daily lighting energy savings of 10 {+-} 15% compared to the reference case with fully lowered Venetian blinds. Cooling load reductions were 0 {+-} 3%. If the reference case assumes no daylighting controls, lighting energy savings would be 44 {+-} 11%. Peak demand reductions due to window cooling load, given a critical demand-response mode, were 19-26% maximum on clear sunny days. Peak demand reductions in lighting energy use were 0% or 72-100% compared to a reference case with and without daylighting controls, respectively. Lighting energy use was found to be very sensitive to how glare and sun is controlled. Additional research should be conducted to fine-tune EC control for visual comfort based on solar conditions so as to increase lighting energy savings.

Advanced fenestration systems for improved daylight performance  

Science Conference Proceedings (OSTI)

The use of daylight to replace or supplement electric lighting in commercial buildings can result in significant energy and demand savings. High performance fenestration systems area necessary, but not sufficient, element of any successful daylighting design that reduces lighting energy use. However, these savings may be reduced if the fenestration systems impose adverse thermal loads. In this paper, we review the state of the art of several advanced fenestration systems which are designed to maximize the energy-saving potential of daylighting, while improving comfort and visual performance at an "affordable" cost. We first review the key performance issues that successful fenestration systems must address, and then review several classes of fenestration systems intended to meet those performance needs. The systems are reviewed in two categories: static and dynamic. Static systems include not only glazings, such as spectrally-selective and holographic glazings, but specialized designs of light-shelves and light-pipes, while dynamic systems cover automatically-operated Venetian blinds and electrochromic glazings. We include a discussion of the research directions in this area, and how these efforts might lead to static and dynamic hardware and system solutions that fulfill the multiple roles that these systems must play in terms of energy efficiency, comfort, visual performance, health, and amenity in future buildings.

Fractal Studies on Titanium-Silica Aerogels using SMARTer  

SciTech Connect

Power-law scattering approximation has been employed to reveal the fractal structures of solid-state titanium-silica aerogel samples. All small-angle neutron scattering (SANS) measurements were performed using 36 meters SANS BATAN spectrometer (SMARTer) at the neutron scattering laboratory (NSL) in Serpong, Indonesia. The mass fractal dimension of titanium-silica aerogels at low scattering vector q range increases from -1.4 to -1.92 with the decrease of acid concentrations during sol-gel process. These results are attributed to the titanium-silica aerogels that are growing to more polymeric and branched structures. At high scattering vector q range the Porod slope of -3.9 significantly down to -2.24 as the roughness of particle surfaces becomes higher. The cross over between these two regimes decreases from 0.4 to 0.16 nm{sup -1} with the increase of acid concentrations indicating also that the titanium-silica aerogels are growing.

Daylighting, dimming, and the electricity crisis in California  

SciTech Connect

Dimming controls for electric lighting have been one of the mainstays of the effort to use daylighting to reduce annual lighting energy consumption. The coincidence of daylighting with electric utility peak demand makes daylighting controls an effective strategy for reducing commercial building peak electric loads. During times of energy shortage, there is a greatly increased need to reduce electricity use during peak periods, both to ease the burden on electricity providers and to control the operating costs of buildings. The paper presents a typical commercial building electric demand profile during summer, and shows how daylighting-linked lighting controls and load shedding techniques can reduce lighting at precisely those times when electricity is most expensive. We look at the importance of dimming for increasing the reliability of the electricity grid in California and other states, as well as examine the potential cost-effectiveness of widespread use of daylighting to save energy and reduce monthly electricity bills.

Daylighting in schools: Energy costs reduced, student performance improved  

Science Conference Proceedings (OSTI)

Ordinarily, architectural-engineering firms are only indirectly concerned with psychological and physical benefits to the occupants of the buildings they design. However, a firm in North Carolina, Innovative Design, is not ordinary. Their use of daylighting in schools yields considerable economic benefits: energy costs reduced up to 64%, cooling and electrical equipment costs reduced, long-term mechanical and lighting equipment maintenance costs reduced. But equally impressive are the benefits of daylighting on student performance. Students in schools using daylighting have higher achievement scores in reading and math tests. Further, as shown in a related study, because of additional vitamin D received by students via daylighting, they will have less dental decay--and grow taller. In the two performance reports which follow, authors Nicklas and Bailey analyze specific win-win benefits of daylighting. Their findings are startling.

Does Daylight Savings Time Affect Traffic Accidents?  

E-Print Network (OSTI)

This paper studies the effect of changes in accident pattern due to Daylight Savings Time (DST). The extension of the DST in 2007 provides a natural experiment to determine whether the number of traffic accidents is affected by shifts in hours of daylight using the year as control group. Using data on traffic accidents in Texas based on crash reports provided by the Texas Transportation Institute, and a difference in differences technique, this study creates a regression model to determine how significant this factor is in affecting traffic accident patterns as observed in the data. Results show that DST has no statistically significant effect on traffic accidents of all categories including (but not limited to) highway, non-highway, and accidents, accidents with injuries and no injuries, and accidents by drivers of all age-groups. This implies that the federal governments policy of DST (and its extension) has no costs incurred by a rise in motor vehicle crashes when it gets dark early.

Minimizing lighting power density in office rooms equipped with Anidolic Daylighting Systems  

Science Conference Proceedings (OSTI)

Electric lighting is responsible for up to one third of an office building's electricity needs. Making daylight more available in office buildings can not only contribute to significant energy savings but also enhance the occupants' performance and wellbeing. Anidolic Daylighting Systems (ADS) are one type of very effective facade-integrated daylighting systems. All south-facing office rooms within the LESO solar experimental building in Lausanne (Switzerland) are equipped with a given type of ADS. A recent study has shown that these offices' occupants are highly satisfied with their lighting environment. The most energy-efficient south-facing offices have a lighting power density of less than 5W/m{sup 2}. The lighting situation within these ''best practice''-offices has been assessed using the lighting simulation software RELUX Vision. Because this lighting situation is very much appreciated by the occupants, it was used as a starting point for developing even more energy-efficient office lighting designs. Two new lighting designs, leading to lighting power densities of 3.9W/m{sup 2} and 3W/m{sup 2}, respectively, have been suggested and simulated with RELUX Vision. Simulation results have shown that the expected performances of these new systems are comparable to that of the current lighting installation within the ''best practice''-offices or even better. These simulation results have been confirmed during experiments on 20 human subjects in a test office room recently set up within the LESO building. This article gives engineers, architects and light planers valuable information and ideas on how to design energy-efficient and comfortable electric lighting systems in office rooms with abundant access to daylight.

An interactive performancebased expert system for daylighting in architectural design  

E-Print Network (OSTI)

ABSTRACT: Architects are increasingly using digital tools during the design process, particularly as they approach complex problems such as designing for successful daylighting performance. However, while simulation tools may provide the designer with valuable information, they do not necessarily guide the user towards design changes which will improve performance. This paper proposes an interactive, goal-based expert system for daylighting design, intended for use during the early design phase. The expert system consists of two major components: a daylighting knowledge-base which contains information regarding the effects of a variety of design conditions on resultant daylighting performance, and a fuzzy rule-based decision-making logic which is used to determine those design changes most likely to improve performance for a given design. The system gives the user the ability to input an initial model and a set of daylighting performance goals in the form of illuminance and daylighting-specific glare metrics. The system acts as a virtual daylighting consultant, guiding the user towards improved performance while maintaining the integrity of the original design and of the design process itself.

Using Daylight to Light the Access Zone of Road Tunnels  

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

Using Daylight to Light the Access Zone of Road Tunnels Using Daylight to Light the Access Zone of Road Tunnels Speaker(s): Eliyahu Ne'eman Date: March 4, 2003 - 12:00pm Location: Bldg. 90 Lighting guides for roadway tunnels specify relatively high luminances for the "access zone" into the tunnel. They are needed to allow the eyes of the driver sufficient time to adapt during the short period of the transition from the outdoor natural daylight levels to the fairly low luminances along the main length of the tunnel. Usually, the necessary high luminances are provided by rows of costly luminaries which consume a lot of electricity during peak use periods and need a good deal of maintenance. To save some electric power, controls are used to dim the lighting on cloudy hours. Daylight has been used for the access zone in several tunnels around the

FREE-SPACE QUANTUM CRYPTOGRAPHY IN DAYLIGHT  

Science Conference Proceedings (OSTI)

Quantum cryptography is an emerging technology in which two parties may simultaneously generate shared, secret cryptographic key material using the transmission of quantum states of light. The security of these transmissions is based on the inviolability of the laws of quantum mechanics and information-theoretically secure post-processing methods. An adversary can neither successfully tap the quantum transmissions, nor evade detection, owing to Heisenberg's uncertainty principle. In this paper we describe the theory of quantum cryptography, and the most recent results from our experimental free-space system with which we have demonstrated for the first time the feasibility of quantum key generation over a point-to-point outdoor atmospheric path in daylight. We achieved a transmission distance of 0.5 km, which was limited only by the length of the test range. Our results provide strong evidence that cryptographic key material could be generated on demand between a ground station and a satellite (or between two satellites), allowing a satellite to be securely re-keyed on orbit. We present a feasibility analysis of surface-to-satellite quantum key generation.

New tools for the evaluation of daylighting strategies and technologies  

SciTech Connect

The use of daylight for the illumination of building interiors has the potential to enhance the quality of the environment while providing opportunities to save energy by replacing or supplementing electric lighting. Moreover, it has the potential to reduce heating and cooling loads, which offer additional energy saving opportunities as well as reductions in HVAC equipment sizing and cost. All of these benefits, however, assume proper use of daylighting strategies and technologies, whose performance depends on the context of their application. On the other hand, improper use can have significant negative effects on both comfort and energy requirements, such as increased glare and cooling loads. To ensure proper use, designers need design tools that model the dynamic nature of daylight and accurately predict performance with respect to a multitude of performance criteria, extending beyond comfort and energy to include aesthetics, cost, security, safety, etc.

Papamichael Conference Name 2003 International Building Performance Simulation Association Conference Date Published 02/2003 Conference Location Eindhoven, Netherlands Call Number LBNL-53003 Abstract Traditional selection of fenestration systems follows a trial-and-error approach, i.e., iterative selection of fenestration systems and evaluation of their performance through the use of simulation tools and techniques. This paper is about the development of a new method, which inverts traditional practice, i.e., aims at automated selection of fenestration systems that best meet specific lighting performance goals. The new method is based on manipulation of matrices that represent the optical properties of fenestration systems, the propagation of light in interior spaces, and the outdoors luminous conditions. The method follows two steps: 1) the determination of the luminous flux distribution originating from the location of the fenestration that best meets the desired lighting performance goals and 2) the selection of the fenestration system that comes closer to producing the desired flux distribution from the outdoor daylight distribution.

Lighting Controls Lighting Controls 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 Lighting Controls The lighting controls scope of work is based upon the philosophy that occupants of commercial office buildings prefer natural light to electric light. 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.

Given novel integrated systems with which contractors (vendors, installers, commissioning (Cx) agents, etc.) do not have much experience, there is a risk that carefully laid plans will go amiss. To insure that the automated shading and daylighting control systems were installed and operating as intended, the manufacturers, LBNL, and the Times Company developed procedures to commission and verify system performance. With verification data resulting from these procedures, the Times Company possessed the unique capability to measure and compare performance to design intent then discuss and tune system performance with the manufacturer prior to closure of the work scope and occupancy of the building.

Analysis of Daylighting Requirements within ASHRAE Standard 90.1  

Science Conference Proceedings (OSTI)

Pacific Northwest National Laboratory (PNNL), under the Building Energy Codes Program (BECP) funded by U.S. Department of Energy (DOE), provides support to the ASHRAE/IES/IESNA Standard 90.1(Standard 90.1) Standing Standards Project Committee (SSPC 90.1) and its subcommittees. In an effort to provide the ASHRAE SSPC 90.1 with data that will improve the daylighting and fenestration requirements in the Standard, PNNL collaborated with Heschong Mahone Group (HMG), now part of TRC Solutions. Combining EnergyPlus, a whole-building energy simulation software developed by DOE, with Radiance, a highly accurate illumination modeling software (Ward 1994), the daylighting requirements within Standard 90.1 were analyzed in greater detail. The initial scope of the study was to evaluate the impact of the fraction of window area compared to exterior wall area (window-to-wall ratio (WWR)) on energy consumption when daylighting controls are implemented. This scope was expanded to study the impact of fenestration visible transmittance (VT), electric lighting controls and daylighted area on building energy consumption.

Energy impact of the use of daylighting in offices  

SciTech Connect

Additional data are provided to permit evaluation and optimization of energy utilization for office type applications with the use of daylighting. The scope of this is limited to the analysis of the sensitivity of the loads of four major parameters: window area, window/wall orientation, the type of glazing and the geographic location. three particular locations, Detroit, Houston, Denver, were selected to depict the influence of different climates. It is desirable to obtain, within practical limits, the lower and upper bounds of the effects of the parameters so as to be able to infer the results for a wide range of values. For this reason the performance of the model was analyzed for ranges of window area from 0 to 100% of the exterior wall area with glazing materials ranging from the single clear to a product of the highest thermal performance such as an insulating and reflecting window. The results for operation without daylighting are used as a baseline of comparison for the daylighting mode. The use of daylighting is found to be effective in reducing the total energy required in office buildings. Even though the heating energy requirement is increased, total energy required is reduced. The model does not include any aspect of the quality of the light, and the results are based on computer simulation, not actual case studies. 16 refs.

SYSTEM REQUIREMENTS GET A COPY DOCUMENTATION KNOWLEDGE BASE Overview Today's energy-efficient windows can dramatically lower the heating and cooling costs associated with windows while increasing occupant comfort and minimizing window surface condensation problems. However, consumers are often confused about how to pick the most efficient window for a residence. Product information typically offers window properties: U-factors or R-values, Solar Heat Gain Coefficients or Shading Coefficients, and air leakage rates. However, the relative importance of these properties depends on site- and building-specific conditions. Furthermore, these properties are based on static evaluation conditions that are very different from the real situation a window will be used in.

Effects of low-emissivity glazings on energy use patterns in nonresidential daylighted buildings  

SciTech Connect

Fenestration is the most significant envelope design determinant of energy use in nonresidential buildings. This paper presents our assessment of energy use effects of low-emissivity (low-E) versus conventional glazings for a range of window-to-wall ratios in a daylighted office building, in representative hot and cold climates. Low-E glazings transmit ''cooler'' daylight than their conventional counterparts because, for a given visible transmittance, they reflect a much larger fraction of incident solar infrared radiation. We thus use the ratio of visible transmittance to shading coefficient, which we define as K/sub e/, to compare the effect of representative glazing characteristics on component and total-building energy use, peak electrical demand, and required cooling equipment sizes. It is concluded that insulated glazings with low-E coatings can provide lighting and cooling energy savings in both hot and cold climates. The most dramatic lighting, cooling, and total electricity energy savings are achieved for increases of K/sub e/ within the range of 0.5 to 1.0; higher K/sub e/s provide diminishing savings. The increased R-value of low-E insulated glass units provides significant benefits in cold climates and is not a liability in hot climates. Low-E glazings also help increase the mean radiant temperature of interior environments in winter and reduce it in summer, and provide greater architectural design freedom without adverse energy consequences. Further, the higher first costs of these glazings may be more than offset by savings from smaller cooling equipment, energy and peak-demand cost savings, long-term financial gains from better rentals, and increased productivity due to improved occupant comfort.

Solar skylight  

DOE Patents (OSTI)

A reflective shutter rotates within a skylight housing in such a fashion as to control solar energy thereby providing a combination of heating, lighting, and ventilation. The skylight housing has three faces: a glazed southern face, a glazed northern face, and an open downwardly oriented face to the interior of the structure. Counter-weighted pivot arms support the shutter at either end causing the center of rotation to pass through the center of gravity. The shutter has three basic positions: In the first position, during the winter day, the shutter closes off the northern face, allowing solar energy to enter directly into the supporting structure providing heat gain and daylighting. In the second position, during the winter night, the shutter closes off the open face to the interior, providing insulation between the structure and the skylight housing. In the third position, during the non-heating season, the shutter closes off the southern face blocking unwanted heat gain but allowing diffuse northern light to penetrate for daylighting. In this last position, a means is provided for ventilating by natural convection. The apparatus can be operated either manually or by motor.

Daylighting in schools: Improving student performance and health at a price schools can afford: Preprint  

SciTech Connect

Over the next seven years, at least 5,000 new schools will be designed and constructed to meet the needs of American students in kindergarten through grade 12. National efforts are underway to encourage the use of daylighting, energy efficiency, and renewable energy technologies in school designs, which can significantly enhance the learning environment. Recent rigorous statistical studies, involving 21,000 students in three states, reveal that students perform better in daylit classrooms and indicate the health benefits of daylighting. This paper discusses the evidence regarding daylighting and student performance and development, and presents four case studies of schools that have cost effectively implemented daylighting into their buildings.

Measurements of sky luminance, sky illuminance, and horizontal solar radiation  

Science Conference Proceedings (OSTI)

This paper presents initial findings of a sky measurement program currently in progress at the National Bureau of Standards. Measurements are reported on sky luminance and illuminance and how they relate to horizontal solar radiation and sun position. Correlations are presented relating horizontal illuminance to horizontal solar radiation, and zenith luminance to solar altitude. These empirical models are particularly suitable for use in daylighting energy studies since they are based on existing solar data currently available on standard weather tapes.

Daylighting practices of the architectural industry (baseline results of a national survey)  

DOE Green Energy (OSTI)

A national survey of over 300 commercial design architects was conducted to develop baseline information on their knowledge, perceptions, and use of daylighting in commercial building designs. Pacific Northwest Laboratory conducted the survey for the US Department of Energy's (DOE) Office of Building and Community Systems (BCS). In the survey daylighting was defined as the intentional use of natural light as a partial substitute for artificially generated light. The results suggested that architects need to be educated about the true benefits of daylighting and the impacts it can have on a building's energy performance. Educational programs that will increase the architects' understanding and awareness of modern daylighting technologies and practices should be developed by utilities, stage agencies, and the federal government. If more architects can be made aware of the true effectiveness and positive attributes of daylighting systems and technologies, daylighting may be used in more commercial buildings. The results of the survey show that the more familiar architects feel they are with daylighting, the more they use daylighting. 3 refs., 19 tabs.

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.

Thermal and Daylighting Performance of an automated venetian blind and lighting system in a full scale private office  

E-Print Network (OSTI)

Dynamic envelope/lighting systems have the potential to optimize the perimeter zone energy balance between daylight admission and solar heat gain rejection on a real-time basis, and to increase occupant comfort. Two side-by-side full-scale offices in Oakland, California were built to further develop and test this concept. An automated venetian blind was operated in synchronization with a dimmable electric lighting system to block direct sun, provide the design workplane illuminance, and maximize view. The research program encompassed system design refinements, energy measurements, and human factors tests. In this study, we present lighting energy and cooling load data that were monitored in this facility over the course of a year. Significant energy savings and peak demand reductions were attained with the automated venetian blind / lighting system compared to a static venetian blind with the same dimmable electric lighting system.

Impact of Extended Daylight Saving Time on National Energy Consumption Report to Congress

The Energy Policy Act of 2005 (Pub. L. No. 109-58; EPAct 2005) amended the Uniform Time Act of 1966 (Pub. L. No. 89-387) to increase the portion of the year that is subject to Daylight Saving Time. (15 U.S.C. 260a note) EPAct 2005 extended the duration of Daylight Saving Time in the spring by changing its start date from the first Sunday in April to the second Sunday in March, and in the fall by changing its end date from the last Sunday in October to the first Sunday in November. (15 U.S.C. 260a note) EPAct 2005 also called for the Department of Energy to evaluate the impact of Extended Daylight Saving Time on energy consumption in the United States and to submit a report to Congress. (15 U.S.C. 260a note) This report presents the results of impacts of Extended Daylight Saving Time on the national energy consumption in the United States. The key findings are: (1) The total electricity savings of Extended Daylight Saving Time were about 1.3 Tera Watt-hour (TWh). This corresponds to 0.5 percent per each day of Extended Daylight Saving Time, or 0.03 percent of electricity consumption over the year. In reference, the total 2007 electricity consumption in the United States was 3,900 TWh. (2) In terms of national primary energy consumption, the electricity savings translate to a reduction of 17 Trillion Btu (TBtu) over the spring and fall Extended Daylight Saving Time periods, or roughly 0.02 percent of total U.S. energy consumption during 2007 of 101,000 TBtu. (3) During Extended Daylight Saving Time, electricity savings generally occurred over a three- to five-hour period in the evening with small increases in usage during the early-morning hours. On a daily percentage basis, electricity savings were slightly greater during the March (spring) extension of Extended Daylight Saving Time than the November (fall) extension. On a regional basis, some southern portions of the United States exhibited slightly smaller impacts of Extended Daylight Saving Time on energy savings compared to the northern regions, a result possibly due to a small, offsetting increase in household air conditioning usage. (4) Changes in national traffic volume and motor gasoline consumption for passenger vehicles in 2007 were determined to be statistically insignificant and therefore, could not be attributed to Extended Daylight Saving Time.

Lee, and Andrew McNeil Conference Name Illuminating Engineering Society (IES) Annual Conference 2013 Date Published 10/2013 Conference Location Huntington Beach, California Keywords building energy efficiency., daylighting, microstructure film, prismatic film, windows Abstract Daylight redirecting systems with vertical windows have the potential to offset lighting energy use in deep perimeter zones. Microstructured prismatic window films can be manufactured using low-cost, roll-to-roll fabrication methods and adhered to the inside surface of existing windows as a retrofit measure or installed as a replacement insulating glass unit in the clerestory portion of the window wall. A clear film patterned with linear, 50-250 micrometer high, four-sided asymmetrical prisms was fabricated and installed in the south-facing, clerestory low-e, clear glazed windows of a full-scale testbed facility. Views through the film were distorted. The film was evaluated in a sunny climate over a two-year period to gauge daylighting and visual comfort performance. The daylighting aperture was small (window-to-wall ratio of 0.18) and the lower windows were blocked off to isolate the evaluation to the window film. Workplane illuminance measurements were made in the 4.6 m (15 ft) deep room furnished as a private office. Analysis of discomfort glare was conducted using high dynamic range imaging coupled with the evalglare software tool, which computes the daylight glare= probability and other metrics used to evaluate visual discomfort.

Effectiveness of External Window Attachments Based on Daylight Utilization and Cooling Load Reduction for Small Office Buildings in Hot Humid Climates  

E-Print Network (OSTI)

This study explored the effectiveness of selected external shading devices and glazing treatments used to minimize the total annual energy consumption in small office buildings in hot humid climates. The external shading devices included a permanent horizontal overhang and a light shelf. The selected types of glazing included clear, reflective, tinted, low-emissivity coating, and heat-mirror glass. One concern about using external window attachments is that while reducing the solar heat gains, they also reduce the amount of the daylight needed to supplement interior lighting. Therefore the objective of this study was to explore which strategy would give a balance between solar heat gain reduction and daylight utilization and result in the most energy savings in the building. Computer simulations using an hourly energy calculation model were conducted to predict the building's total energy consumption using each strategy. The economics of each strategy were analyzed with lifecycle costing techniques using the present value technique. Results show that properly designed overhangs that shade clear glazing are slightly more cost-effective than specialized low-e glazing systems. These results are unique for hot humid climates where winter heating is not an issue. On the contrary, when used in cold climates, external shading devices tend to increase the building's energy consumption.

Performance of Anidolic Daylighting Systems in tropical climates - Parametric studies for identification of main influencing factors  

Science Conference Proceedings (OSTI)

Making daylight more available in buildings is highly desirable, not only for reasons of energy-efficiency, but also for improvement of occupants' health and well-being. Core-daylighting, that is daylight provision in areas situated at considerable distances from facades and windows, is currently one of the main challenges in sustainable building design. Anidolic Daylighting Systems (ADSs) are one very promising technology in the field of core-daylighting, but commercial solutions that are not only well-performing but also financially competitive are not yet widely available. This article presents results of parametric studies on Anidolic Integrated Ceilings (AICs), a special type of ADS, for identification of main influencing factors. The article describes a reliable method for simulating ADS and AIC performance under given sky conditions. Various simulation results for the example location Singapore are discussed in detail, it is concluded that the main influencing factors are coating material, system dimensions and external obstruction, and those influencing factors' potential impacts are quantified. It is shown that AIC overall efficiencies can reach up to almost 50% in Singapore. The essentially new results presented in this article can be of great help to architects, engineers and scientists in the future, when it comes to precisely dimensioning ADS for various buildings and daylight conditions.

Energy, Shading and Daylighting Analysis for the Austin Bergstrom International Airport Terminal  

E-Print Network (OSTI)

Our firm was under contract with the City of Austin, Texas to perform energy analysis and analysis of the daylighting potential within the New Austin Bergstrom International Airport Terminal. Design of the Passenger Terminal Facility for the New Austin Airport included large glass areas for viewing arriving and departing planes, the sky, and the surrounding terrain. The glass was envisioned to provide quality natural lighting for the terminal during daylight hours in order to improve the quality of the space and save energy throughout the usable life of the terminal. For the glass to achieve the design goals, adverse qualities were minimized and beneficial qualities must be enhanced. Using computer simulation, we studied the shading devices on the south clearstories to maximize the daylight and minimize problems of direct gain in a large commercial space. The study also included analysis of skylights above the baggage claim, indirect lighting of major spaces within the airport, and the controls of the artificial lights for integrating the efficient use of the available daylight. The energy, shading, and daylighting analysis includes analysis of a mix of low and high volume spaces. The daylight sources include glass walls, clearstories, and skylights.

Determining daylight illuminance in rooms having complex fenestration systems  

SciTech Connect

Traditional computational models predict daylight illuminance in a space by dividing window surfaces into discrete areas and then calculating the apparent luminance of each window element by multiplying the luminance of the natural light source in a given viewing direction by the window transmittance in that direction. This approach works well for conventional glazing materials but is incapable of modeling commonly used, but complex, window systems such as those with specular reflective venetian blinds. We describe a new approach that combines measured luminance distributions for complex window systems with a flux transfer calculation within the space. This method resembles the calculation of illuminance from electric light fixtures where the candlepower distribution of the fixtures is measured and used as an input to the calculation. Based on the variable luminance characteristics of the window system, the SUPERLITE program calculates illuminance at the workplane over the entire space. The measurement techniques and mathematical implementation in the SUPERLITE program are described. This approach allows a wide range of complex and shading systems to be evaluated without continuous changes in the computational program. A special apparatus for measuring the bidirectional transmittance of window systems has been built in conjunction with this approach. Sample results from the program are compared to measurements made in scale models in a sky simulator. 5 refs., 6 figs.

Daylighting techniques used in indigenous buildings in the United Arab Emirates (UAE), an investigative approach  

E-Print Network (OSTI)

This study investigated the potential of the daylighting systems used in the indigenous architecture of the United Arab Emirates (UAE), located in Dubai (latitude 25 N longitude 55 E). The analysis tested the lighting performance of three daylighting systems under UAE climatic conditions. The purpose of this research was to investigate the daylighting performance of three of the most common daylighting systems found in the indigenous buildings of the UAE, traditional windows (Dreeshah), gypsum decorative panels and wind tower (Barjeel). The lighting performance of each of the three lighting systems was examined. The lighting performance parameters examined were illuminance level, light distribution, uniformity, and glare. IESNA standards, CIBSE guidelines and LEED 2.2 daylighting credit and recommendations were used as the minimum recommended level for all analyzed variables. On-site measurements (illuminance and luminance) were conducted to compare measured versus simulated measurements inside the space. Desktop Radiance 2.0 Beta was used as the lighting performance analysis tool under clear sky conditions. Results have shown that the gypsum decorative panel performs better than the other two systems in terms of light uniformity and distribution, regardless of a lower illuminance level. The double panel window prototype has poor lighting performance in terms of glare, light distribution and uniformity. Wind tower performed well under the area of the wind tower itself. Apart from that it also had a poor lighting performance in terms of glare, light distribution, and uniformity.

Performance of Integrated Systems of Automated Roller Shade Systems and Daylight Responsive Dimming Systems  

Science Conference Proceedings (OSTI)

Daylight responsive dimming systems have been used in few buildings to date because they require improvements to improve reliability. The key underlying factor contributing to poor performance is the variability of the ratio of the photosensor signal to daylight workplane illuminance in accordance with sun position, sky condition, and fenestration condition. Therefore, this paper describes the integrated systems between automated roller shade systems and daylight responsive dimming systems with an improved closed-loop proportional control algorithm, and the relative performance of the integrated systems and single systems. The concept of the improved closed-loop proportional control algorithm for the integrated systems is to predict the varying correlation of photosensor signal to daylight workplane illuminance according to roller shade height and sky conditions for improvement of the system accuracy. In this study, the performance of the integrated systems with two improved closed-loop proportional control algorithms was compared with that of the current (modified) closed-loop proportional control algorithm. In the results, the average maintenance percentage and the average discrepancies of the target illuminance, as well as the average time under 90percent of target illuminance for the integrated systems significantly improved in comparison with the current closed-loop proportional control algorithm for daylight responsive dimming systems as a single system.

E-Print Network (OSTI)

Daylighting and other passive energy technologies are critical issues that should be considered in the early stages of building planning and architectural design. Both new design and retrofit of existing buildings benefit greatly by use of microcomputer-generated models, especially as they relate to building studies in zones of extreme climate. The hot, humid environment of Louisiana poses unique problems and calls for creative solutions. The use of microcomputers as analytical tools to develop suggestions for optimizing the amount of energy consumed for lighting and climatic comfort is illustrated. The effective use of daylighting can, as might be expected, produce net energy savings in most school buildings.

Annual daylighting performance of a passive optical light shelf in sidelit  

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

Annual daylighting performance of a passive optical light shelf in sidelit Annual daylighting performance of a passive optical light shelf in sidelit perimeter zones of commercial buildings Title Annual daylighting performance of a passive optical light shelf in sidelit perimeter zones of commercial buildings Publication Type Report Year of Publication 2013 Authors McNeil, Andrew, and Eleanor S. Lee Keywords bidirectional scattering distribution functions, building energy efficiency, daylighting, Radiance simulations Abstract Sunlight redirecting systems have the potential to significantly offset electric lighting energy use in deep perimeter zones of buildings where the windows are subject to high daylight availability. New Radiance modeling tools have recently been developed and validated, enabling accurate and timely simulation analysis of the annual energy and comfort performance of these optically-complex, anisotropic systems. A parametric study was conducted using these tools to evaluate the performance of a commercially-available passive optical light shelf (OLS) in a 17.4 m deep (57 ft), south-facing open plan office zone in three climates. Daylighting efficiency, discomfort glare, and lighting energy savings with continuous dimming and bi-level switching controls were determined at varying depths within the zone. The OLS decreased lighting energy use significantly throughout the depth of the space and achieved these savings with minimal discomfort glare in the area near the window. Annual lighting energy use intensity was reduced to 1.71-1.82 kWh/ft2-yr (22-27%) over the full depth of the perimeter zone across the three climates modeled (Phoenix, Washington DC, and Minneapolis) compared to a non-daylit zone at 2.34 kWh/ft2-yr. There was a greater occurrence of discomfort glare (3-7% during daytime work hours) if the occupant was in a seated view position looking at the window from the back of the room. The system is passive, needing no adjustment during the day and over the seasons and can be used as a retrofit measure in existing buildings. These results are encouraging and demonstrate how the primary daylit sidelit area can be extended well beyond the defined limits provided by the newly adopted ASHRAE 90.1-2010 code (i.e., 1.0 times the head height of the window).

ADAPTIVE FULL-SPECTRUM SOLAR ENERGY SYSTEMS Cross-Cutting R & D on adaptive full-spectrum solar energy systems for more efficient and affordable use of solar energy in buildings and hybrid photobioreactors  

DOE Green Energy (OSTI)

This RD&D project is a three year team effort to develop a hybrid solar lighting (HSL) system that transports daylight from a paraboloidal dish concentrator to a luminaire via a bundle of polymer fiber optics. The luminaire can be a device to distribute sunlight into a space for the production of algae or it can be a device that is a combination of daylighting and electric lighting for space/task lighting. In this project, the sunlight is collected using a one-meter paraboloidal concentrator dish with two-axis tracking. For the third generation (beta) system, the secondary mirror is an ellipsoidal mirror that directs the visible light into a bundle of 3 mm diameter fibers. The IR spectrum is filtered out to minimize unnecessary heating at the fiber entrance region. This report describes the following investigations: Niche applications for HSL technology, Luminaire design characteristics for linear and point lighting fixtures, and Daylight affects on productivity.

Towards Embedded Wireless-Networked Intelligent Daylighting Systems for Commercial Buildings  

E-Print Network (OSTI)

Energy efficient office lighting systems can save 40% in electricity consumption in areas that receive significant amounts of daylight. In spite of the savings they can generate, daylighting systems are not widely used in the commercial office building. Barriers prohibiting adoption include high retrofitting costs, and difficulty estimating and maintaining worksurface illuminances. In this paper, an intelligent control framework that utilizes MEMS-based (micro-electro-mechanical systems) Smart Dust motes wireless platforms is explored. Due to their small size, they can be placed directly on the worksurface. As a result, illuminance estimation and maintenance is significantly improved. Furthermore, motes functioning as actuators can be interfaced with dimming ballasts without the need to rewire the building, enabling less expensive, less disruptive retrofitting of commercial buildings.

Design and Analysis of Hybrid Solar Lighting and Full-Spectrum Solar Energy Systems  

DOE Green Energy (OSTI)

This paper describes a systems-level design and analysis of a new approach for improving the energy efficiency and affordability of solar energy in buildings, namely, hybrid solar lighting and full-spectrum solar energy systems. By using different portions of the solar spectrum simultaneously for multiple end-use applications in buildings, the proposed system offers unique advantages over other alternatives for using sunlight to displace electricity (conventional topside daylighting and solar technologies). Our preliminary work indicates that hybrid solar lighting, a method of collecting and distributing direct sunlight for lighting purposes, will alleviate many of the problems with passive daylighting systems of today, such as spatial and temporal variability, glare, excess illumination, cost, and energy efficiency. Similarly, our work suggests that the most appropriate use of the visible portion of direct, nondiffuse sunlight from an energy-savings perspective is to displace electric light rather than generate electricity. Early estimates detailed in this paper suggest an anticipated system cost of well under $2.0/Wp and 5-11 {cents}/kWh for displaced and generated electricity in single-story commercial building applications. Based on a number of factors discussed in the paper, including sunlight availability, building use scenarios, time-of-day electric utility rates, cost, and efficacy of the displaced electric lights, the simple payback of this approach in many applications could eventually be well under 5 years.

On the Use of Integrated Daylighting and Energy Simulations to Drive the Design of a Large Net-Zero Energy Office Building: Preprint  

SciTech Connect

This paper illustrates the challenges of integrating rigorous daylight and electric lighting simulation data with whole-building energy models, and defends the need for such integration to achieve aggressive energy savings. Through a case study example, we examine the ways daylighting -- and daylighting simulation -- drove the design of a large net-zero energy project. We give a detailed review of the daylighting and electric lighting design process for the National Renewable Energy Laboratory's Research Support Facility (RSF), a 220,000 ft2 net-zero energy project the author worked on as a daylighting consultant. A review of the issues involved in simulating and validating the daylighting performance of the RSF will be detailed, including daylighting simulation, electric lighting control response, and integration of Radiance simulation data into the building energy model. Daylighting was a key strategy in reaching the contractual energy use goals for the RSF project; the building's program, layout, orientation and interior/furniture design were all influenced by the daylighting design, and simulation was critical in ensuring these many design components worked together in an integrated fashion, and would perform as required to meet a very aggressive energy performance goal, as expressed in a target energy use intensity.

The Texas Solar D House  

E-Print Network (OSTI)

The Solar Decathlon provided a national forum for competition among fourteen university student teams, each of which designed, built, and operated a totally solar-powered home with a home office and their transportation needs using a solar-charged vehicle. The competition took place on the National Mall in Washington D.C., where each house was constructed and operated from September 18 to October 10, 2002. The competition consisted of ten contests focusing on energy production, energy-efficiency, design, thermal comfort, refrigeration, lighting, communication and transportation Professor Michael Garrison of the School of Architecture directed the University of Texas at Austin (UT) Solar Decathlon team along with Pliny Fisk, codirector of the non-profit Center for Maximum Potential Building Systems in Austin, Texas. The graduate student team developed a design that features an open building system using a reusable kit of parts that sits lightly on the land and forms the superstructure around a mobile utility environment. Our investigations suggest that progressive technologies offer solutions to the serious emerging challenges of energy efficiency and sustainable development and thereby become a strong design shaping force. These progressive technologies: photovoltaic (PV) power, passive solar heating, daylighting, natural ventilation, and solar hot water heating were integrated with concepts of affordability and energy conservation to help promote an ideology of sustainable architecture.

Plasma lighting, fiber optics, and daylight collectors: Toward the next revolution in high-efficiency illumination  

SciTech Connect

Combining three recently marketed innovations may provide the next revolution in illumination, making many other recent advances eventually obsolete. The first is plasma lighting, pioneered by Fusion Lighting Inc. of Rockville, Maryland, and first commercially applied by Hutchins International Ltd. of Mississauga, Ontario. This microwave-generated light source yields very high-quality light with efficacies at or beyond high intensity discharge (HID) lamps. The source uses no mercury, thus eliminating lamp disposal problems, and has no cathode, thereby providing very long lamp life. Using no phosphors, it also has very short start and re-strike periods, and is dimmable. The second innovation is in the distribution of light. Commercial developments in fiber optics and light guides now provide products that transfer light from a remote point and distribute it like standard light fixtures. Advances in fiber optic communications and applications to decorative lighting have supplied relatively economical systems for mounting and directing light from both electric light sources and the sun. The third advance is a result of efforts to harness daylight. Unlike architectural daylighting that directs sunlight into perimeter areas through glazing, daylight collectors are roof-mounted devices that supply light to interior and underground spaces through hollow columns and open chases. Aided by improvements and cost reductions in sun-tracking (i.e., heliostatic) controls that capture and concentrate sunlight, such collectors offer a source of free light to locations that might otherwise never receive it. When combined together, these three options could offer a centralized building lighting system that pipes lumens to distribution devices replacing many existing lamps and fixtures.

Procedure for calculating interior daylight illumination with a programmable hand calculator  

DOE Green Energy (OSTI)

A procedure is described for calculating interior daylight illumination using an inexpensive programmable hand calculator. The proposed procedure calculates illumination at any point within a room utilizing sky luminance distribution functions that are consistent with the CIE (Commission Internationale de l'Eclairage) Overcast and Clear Sky functions. This procedure separates the light reaching the point being considered into three components, these being (a) light directly from the sky, (b) light after being reflected from external, and (c) internal surfaces. Finally, two examples are presented in order to demonstrate the proposed procedure and indicate the speed with which the calculations may be performed.

Simulating the Daylight Performance of Complex Fenestration Systems Using Bidirectional Scattering Distribution Functions within Radiance  

SciTech Connect

We describe two methods which rely on bidirectional scattering distribution functions (BSDFs) to model the daylighting performance of complex fenestration systems (CFS), enabling greater flexibility and accuracy in evaluating arbitrary assemblies of glazing, shading, and other optically-complex coplanar window systems. Two tools within Radiance enable a) efficient annual performance evaluations of CFS, and b) accurate renderings of CFS despite the loss of spatial resolution associated with low-resolution BSDF datasets for inhomogeneous systems. Validation, accuracy, and limitations of the methods are discussed.

Measuring solar heat reduction for draperies and fabric shades  

SciTech Connect

We are all familiar with the utility of draperies, curtains and shades to exclude unwanted solar gain, control glare, insulate windows and provide privacy. The manageability of these devices gives us a degree of control over our indoor environment. While fabric window coverings are widely used as interior shading devices, the analytical methods used to determine their effectiveness in reducing solar gains are relatively unsophisticated. Furthermore, with the recent emphasis on daylighting and visual and thermal comfort, the response to these shading devices to the varying direction of incident solar radiation has taken on a new importance. In this article, the authors review the historical development of analytical and experimental methods used to determine solar heat gain for draperies. The current state of these methods will be evaluated and issues related to their applicability to draperies and fabric shades are identified. Finally, recommendations to improve the accuracy and applicability of current solar heat gain methods are presented.

Hybrid Solar Lighting - Fiber Optics Brings Sunlight Inside  

Science Conference Proceedings (OSTI)

Hybrid solar lighting systems focus highly concentrated sunlight into a fiber optic bundle to provide sunlight in rooms without windows or conventional skylights. The flexible sunlight bundles are easily routed through small openings and around obstacles to carry the light to where it is needed. The optical fibers terminate in hybrid luminaires where the sunlight is combined with electric light that is automatically adjusted to keep the overall light level constant within the lighted area. The hybrid solar lighting concept was originally proposed at Oak Ridge National Laboratory in Tennessee in the mid-1990s, but funding hurdles prevented the idea from seeing daylight for more than five years. Hybrid solar lighting was touted as a means for using solar energy directly without any conversion losses and for increasing the visual quality of interior lighting. As such, it promised to be both energy-efficient and aesthetically appealing, but its technical complexity made potential sponsors wary. They had to be convinced that the lighting concept could be accepted into the marketplace and that the systems could be manufactured at an acceptable cost. An earlier fiber-coupled daylighting system marketed in the early 1990s used expensive quartz optical fibers to distribute the light and served only a niche market that was willing to pay a premium for the novelty. By contrast, the hybrid solar lighting system proposed using inexpensive plastic optical fibers to distribute the light to hybrid (sunlight/electric) luminaires that would be visually and functionally identical to conventional luminaires. In this way, the lighting could be integrated seamlessly into existing design concepts and thus easily embraced by architects and lighting designers as a means for offering daylight as a lighting option.

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)

Energy Use Intensity and its Influence on the Integrated Daylighting Design of a Large Net Zero Energy Building: Preprint  

SciTech Connect

Net-zero energy buildings generate as much energy as they consume and are significant in the sustainable future of building design and construction. The role of daylighting (and its simulation) in the design process becomes critical. In this paper we present the process the National Renewable Energy Laboratory embarked on in the procurement, design, and construction of its newest building, the Research Support Facility (RSF) - particularly the roles of daylighting, electric lighting, and simulation. With a rapid construction schedule, the procurement, design, and construction had to be tightly integrated; with low energy use. We outline the process and measures required to manage a building design that could expect to operate at an efficiency previously unheard of for a building of this type, size, and density. Rigorous simulation of the daylighting and the electric lighting control response was a given, but the oft-ignored disconnect between lighting simulation and whole-building energy use simulation had to be addressed. The RSF project will be thoroughly evaluated for its performance for one year; preliminary data from the postoccupancy monitoring efforts will also be presented with an eye toward the current efficacy of building energy and lighting simulation.

An experimental setup to evaluate the daylighting performance of an advanced optical light pipe for deep-plan office buildings  

E-Print Network (OSTI)

This research focuses on an advanced optical light pipe daylighting system as a means to deliver natural light at the back of deep-plan office buildings (15ft to 30ft), using optimized geometry and high reflective materials. The light pipe configurations follow a previous study at the Lawrence Berkeley National Laboratory (Beltr??n et al., 1997). The current system is designed for College Station, TX (lat: 30?? 36??N), with predominantly mostly sunny sky conditions. This work consists of the monitoring of two scale models simulating a portion of a multi-story office building with open-plan configuration, with interior dimensions 30ft x 20ft x 10ft, built at 1:4 of its real scale, one of the models being the reference case and the other the test case where the light pipe system is placed. The main objectives of this thesis are (a) to examine this daylighting system comparative to the reference case, taking measurements for longer periods than the study at LBNL, as well as to collect detailed data of its performance under different weather conditions and with different materials; (b) to evaluate the visual comfort and possible glare problems of the light pipe system through photographic evaluation and the conduction of a survey that provides people??s opinions and suggestions about the daylighting system. The light pipe system demonstrated a higher performance than the reference case in terms of appropriate levels of light and people??s preferences. The illuminance at the workplane level showed to be adequate with any of the two different diffusing materials used to spread the light into the room. The light pipe without a diffuser was the other condition observed to further understand the bounces of the sunbeam inside the reflective chamber and its consequences on the lighting output. Recommended standards for office spaces with VDT screens together with the analysis of the daylight system, led to preliminary suggestions on how to integrate the light pipe system in an open-plan office configuration. Further study is indicated to reach the complete potential of this advanced optical light pipe that ties illuminance quality with energy savings through the integration of daylight and electric light systems.

Highlighting High Performance: The Solar Energy Research Facility, Golden, Colorado  

DOE Green Energy (OSTI)

The National Renewable Energy Laboratory's Solar Energy Research Facility in Golden, Colorado, uses a stair-step configuration to allow daylight and heat into the office areas, while the laboratories in the back of the building are in a more controlled environment where tight levels of ventilation, humidity, temperature, and light are critical. A unique mechanical system makes the most of the natural environment and the building's design to efficiently heat and cool the building at an annual utility bill savings of almost $200,000 per year.

Daylighting: Measuring the Performance of Light Shelves and Occupant-Controlled Blinds on a Dimmed Lighting Systems  

E-Print Network (OSTI)

The design of a day lighted space is both an art and a science. The biggest challenge facing the lighting designer is to admit only as much light as necessary and distribute it evenly throughout the space without introducing glare or heat. In warm climates such as Florida, it has become common practice in windowed spaces to specify blinds and glazing with high shading coefficients to control glare and minimize heat gain. However, this practice reduces the effectiveness of lighting systems that dim automatically. Improved systems are needed to capture natural daylight and distribute it uniformly throughout a space while controlling heat gain and glare. One such system is the light shelf. Light shelves shade the space from direct sunlight and reflect this sunlight onto the ceiling for a deeper and more uniform distribution. While this is not a new idea, little unbiased empirical data has been collected, outside the laboratory, that compares the performance (energy savings, uniformity, and level) of an automatic daylighting system. This study measures the effectiveness of light shelves and manually controlled horizontal blinds in an automatic daylighting system. Power consumption and interior work-plane lighting levels were compared in four essentially identical private offices. Two offices were configured with an interior light shelf, one with a white diffuse top surface and the other with a specular surface. The third office had no window treatment and the fourth office had horizontal blinds, which were manually adjusted by the user. All offices had two lamp fluorescent luminaires with dimming ballasts (min. 20%) controlled by a ceiling mounted photosensor. The study showed that daytime savings ranged from 29% to 46%, with the largest savings from the office with the light shelves. The office with horizontal blinds showed the poor savings (32%) and also the poorest light uniformity and level.

Use of an atrium for the passive-solar retrofit of an office building: design and installation experience  

DOE Green Energy (OSTI)

A clerestory window system has been installed over a courtyard in an existing two-story office building/museum at the Los Alamos National Laboratory, thus creating an atrium. This atrium serves as a passive solar heating and daylighting system for the building and provides new display space for the museum. The retrofit consists of a roof-mounted clerestory window system with night insulating shutters which: forms an atrium that provides new museum space, buffers the former courtyard walls and windows, preheats ventilation air for the entire building, and provides daylighting and heating for the new museum space. The passive system is coupled to the heating, ventilating, and air-conditioning (HVAC) system of the surrounding building by inducing fresh-air makeup through the solar-tempered atrium; heating, cooling, and daylighting are addressed in the design. The design process, the use of the DOE-2 building energy analysis computer program during design, and the construction of the atrium are described.

Technical and economic assessment of solar hybrid repowering. Final report  

DOE Green Energy (OSTI)

Public Service Company of New Mexico (PNM) has performed a Technical and Economic Assessment of Solar Hybrid Repowering under funding by the Department of Energy (DOE), the Electric Power Research Institute (EPRI), Western Energy Supply and Transmission (WEST) Associates, and a number of southwestern utilities. Solar hybrid repowering involves placement of solar hardware adjacent to and connected to existing gas- and oil-fueled electric generation units to displace some of or all the fossil fuel normally used during daylight hours. The subject study assesses the technical economic viability of the solar hybrid repowering concept within the southwestern United States and the PNM system. This document is a final report on the study and its results. The study was divided into the six primary tasks to allow a systematic investigation of the concept: (1) market survey and cost/benefit analysis, (2) study unit selection, (3) conceptual design and cost estimates, (4) unit economic analysis, (5) program planning, future phases, and (6) program management. Reeves Station No. 2 at Albuquerque, New Mexico, was selected for repowering with a design goal of 50 percent (25 MWe). The solar system design is based on the 10 MW solar central receiver pilot plant preliminary design for Barstow, California. SAN--1608-4-2 contains the technical drawings. (WHK)

Passive Solar Design: The Foundation for Low-Energy Federal Buildings  

DOE Green Energy (OSTI)

This fact sheet updates a similar one published in 1996 for the U.S. Department of Energy's Federal Energy Management Program. It is part of a series of fact sheets on ways that the Federal government can incorporate new energy efficiency, solar energy, and other renewable energy technologies in buildings and other facilities to save on energy costs and reduce greenhouse gas emissions. This fact sheet describes strategies for implementing passive solar features--such as south-facing windows, daylighting, and thermal mass--into new building designs and retrofits. It also discusses how to design and build low-energy, sustainable buildings by using a whole-building approach to the design process. In this approach, designers not only use passive solar techniques, they also create a design that makes the most of the complex ways that a building's occupants, components, and materials connect and interact in order to achieve the greatest possible comfort and energy efficiency.

ADAPTIVE FULL-SPECTRUM SOLAR ENERGY SYSTEMS CROSS-CUTTING R&D ON ADAPTIVE FULL-SPECTRUM SOLAR ENERGY SYSTEMS FOR MORE EFFICIENT AND AFFORDABLE USE OF SOLAR ENERGY IN BUILDINGS AND HYBRID PHOTOBIOREACTORS  

DOE Green Energy (OSTI)

This RD&D project is a three year team effort to develop a hybrid solar lighting (HSL) system that transports daylight from a paraboloidal dish concentrator to a luminaire via a bundle of small core or a large core polymer fiber optics. The luminaire can be a device to distribute sunlight into a space for the production of algae or it can be a device that is a combination of daylighting and electric lighting for space/task lighting. In this project, the sunlight is collected using a one-meter paraboloidal concentrator dish with two-axis tracking. For the second generation (alpha) system, the secondary mirror is an ellipsoidal mirror that directs the visible light into a bundle of small-core fibers. The IR spectrum is filtered out to minimize unnecessary heating at the fiber entrance region. This report describes the following investigations of various aspects of the system. Taken as a whole, they confirm significant progress towards the technical feasibility and commercial viability of this technology. (1) TRNSYS Modeling of a Hybrid Lighting System: Building Energy Loads and Chromaticity Analysis; (2) High Lumens Screening Test Setup for Optical Fibers; (3) Photo-Induced Heating in Plastic Optical Fiber Bundles; (4) Low-Cost Primary Mirror Development; (5) Potential Applications for Hybrid Solar Lighting; (6) Photobioreactor Population Experiments and Productivity Measurements; and (7) Development of a Microalgal CO2-Biofixation Photobioreactor.

www.ucei.org Valuing the Time-Varying Electricity Production of Solar Photovoltaic Cells  

E-Print Network (OSTI)

Abstract: Solar PV panels generate electricity only during daylight hours and generate more electricity when the sun is shining more intensely. As a result, in summer-peaking electricity systems, such as California and most of the U.S., power from PVs is produced disproportionately at times when the value of electricity is high. Thus, a valuation of solar PV electricity production that uses only the average wholesale cost of electricity will tend to undervalue the power. Yet, that is what happens by default in many installations because solar PVs are generally located at the end-users premises and those end-users are often billed on a flat per kilowatt-hour rate that does not reflect time-varying valuation. As a result, the benefits to many owners of solar PV in reduced electricity bills do not reflect thetruetime-varyingvaluationofthepowerthepanelsproduce. IusesolarPVproduction information in conjunction with wholesale price data and simulations to estimate the actual wholesale value of power from solar PVs and the degree of bias that occurs from using a constant price to value electricity generated by solar PVs. I find that in the California locations I analyze, the most credible long-run valuation of solar PV power is 29%-48% greater than results from valuation at a flat-rate tariff, depending on the location of the PV

Solar ponds  

DOE Green Energy (OSTI)

The different types of solar ponds are described, including the nonconvecting salt gradient pond and various saltless pond designs. Then the availability and cost of salts for salt gradient ponds are discussed and costs are compared. A simple computational model is developed to approximate solar pond performance. This model is later used to size solar ponds for district heating and industrial process heat applications. For district heating, ponds are sized to provide space conditioning for a group of homes, in different regions of the United States. Size requirement is on the order of one acre for a group of 25 to 50 homes. An economic analysis is performed of solar ponds used in two industrial process heat applications. The analysis finds that solar ponds are competitive when conventional heat sources are priced at $5 per million Btu and expected to rise in price at a rate of 10% per year. The application of solar ponds to the generation of electricity is also discussed. Total solar pond potential for displacing conventional energy sources is estimated in the range of from one to six quadrillion Btu per year in the near and intermediate future.

Solar Two is a concentrating solar power plant that can supply electric power on demand to the local utility, Southern California Edison Company. It can do so because it operates not only during sunny parts of the day, but it can store enough thermal energy from the sun to operate during cloudy periods and after dark, for up to three hours, at its rated output of 10 megawatts (MW). For the first time ever, a utility scale solar power plant can supply electricity when the utility needs it most, to satisfy the energy requirements of its customers.

Solar-energy-system performance evaluation, April-August 1982, University of Minnesota Bookstore, Minneapolis, Minnesota  

DOE Green Energy (OSTI)

The solar system at the University of Minnesota Bookstore provided a total of 5% of the combined space heating and cooling load of 825 million Btu. The solar savings ratio, which accounts for operating energy used to collect solar energy, was 0.02. The fossil energy savings were 154.6 million Btu, equivalent to nine tons of coal, but there was an electrical energy expense of 19.2 million Btu (5620 kwh). The system had a net energy savings of $49.09 based on energy costs of $41.36 per ton of coal and 5.75 cents per kwh. Major energy flows to the heating and cooling subsystems are presented in the Energy Flow Diagram. In terms of solar energy utilization, the space cooling subsystem used 82 million Btu compared to 10.7 million Btu used in the space heating subsystem. The active solar energy system was retrofitted in 1979 on a relatively new earth-sheltered building which houses a bookstore, admissions and records facility. The building is 95% below ground for energy conservation and to preserve open space on the campus. Other energy conservation features are triple glazing on the windows, clerestories for daylighting and passive solar energy collection in winter, and a warm-air heat recovery system on the ventilation air. Due to the energy conservation features, the solar collection subsystem could be downsized and still provide large solar fractions. The solar collector array is comprised of six stationary units of 10 movable reflectors, each about 110 feet long and one foot wide. These glass mirrors concentrate sunlight onto a copper absorber tube receiver. Solar heated water from the storage tank or the collector array and water heated with auxiliary steam via a heat exchanger are delivered to a 147-ton absorption chiller for space cooling or to the heating coils for space heating.

ADAPTIVE FULL-SPECTRUM SOLAR ENERGY SYSTEMS CROSS-CUTTING R&D ON ADAPTIVE FULL-SPECTRUM SOLAR ENERGY SYSTEMS FOR MORE EFFICIENT AND AFFORDABLE USE OF SOLAR ENERGY IN BUILDINGS AND HYBRID PHOTOBIOREACTORS  

DOE Green Energy (OSTI)

This RD&D project is a three year team effort to develop a hybrid solar lighting (HSL) system that transports daylight from a paraboloidal dish concentrator to a luminaire via a bundle of small core or a large core polymer fiber optics. The luminaire can be a device to distribute sunlight into a space for the production of algae or it can be a device that is a combination of daylighting and electric lighting for space/task lighting. In this project, the sunlight is collected using a one-meter paraboloidal concentrator dish with two-axis tracking. For the second generation (alpha) system, the secondary mirror is an ellipsoidal mirror that directs the visible light into a bundle of small-core fibers. The IR spectrum is filtered out to minimize unnecessary heating at the fiber entrance region. This report describes the following investigations of various aspects of the system: (1) Performance specifications were developed for the tracking subsystem and collector optics, (2) Thermal management experiments for the fiber optic bundle entrance region, and (3) Bioreactor testing, cost-modeling, and redesign. Much of the planned work has been slowed due to significant procurement delays of the primary mirror. However, taken as a whole, they do confirm progress towards the technical feasibility and commercial viability of this technology. Due to this procurement delay, a no-cost extension of the project completion date has been requested and approved.

Measurements of insolation variation over a solar collector field  

DOE Green Energy (OSTI)

The experiment described in this report makes observations to determine the direct insolation every 16 sec at corners of a quadrilateral approximately 600 meters in size located near Barstow, California. This size approximates the collector field of the solar power plant to be built near Barstow. Data from the first three months of operation of this experiment indicate cloudy conditions, capable of affecting the operation of a solar power plant, occurred during 15% of the daylight hours of some months. Patterns of insolation variation over the experiment area indicate shadows often exist with dimensions less than the projected size of the collection field for the 10 MW/sub e/ solar thermal power plant. Detailed statistical summaries of four partly cloudy events are included. Rates of insolation change on an individual sensor greater than or equal to 30 Wm/sup -2/ sec/sup -1/ have been observed, but these rate measurements have probably been limited by the response time of the experimental system. Spatial averaging of the measured insolation over the sensor field lowers the rate of insolation change.

Performance of solar heating and cooling systems: Solid desiccant cooling/fresh air heating with evacuated-tube collectors in CSU Solar House I  

DOE Green Energy (OSTI)

In keeping with the national energy policy goal of fostering an adequate supply of energy at a reasonable cost, the United States Department of Energy (DOE) supports a variety of programs to promote a balanced and mixed energy resource system. The mission of the DOE Solar Buildings Research and Development Program is to support this goal, by providing for the development of solar technology alternatives for the buildings sector. It is the goal of the Program to establish a proven technology base to allow industry to develop solar products and designs for buildings that are economically competitive and can contribute significantly to building energy supplies nationally. Toward this end, the program sponsors research activities related to increasing the efficiency, reducing the cost, and improving the long-term durability of passive and active solar systems for building water and space heating, cooling, and daylighting applications. These activities are conducted in four major areas: Advanced Passive Solar Materials Research, Collector Technology Research, Cooling Systems Research, and Systems Analysis and Applications Research.

Solar Neutrinos  

DOE R&D Accomplishments (OSTI)

The prospect of studying the solar energy generation process directly by observing the solar neutrino radiation has been discussed for many years. The main difficulty with this approach is that the sun emits predominantly low energy neutrinos, and detectors for observing low fluxes of low energy neutrinos have not been developed. However, experimental techniques have been developed for observing neutrinos, and one can foresee that in the near future these techniques will be improved sufficiently in sensitivity to observe solar neutrinos. At the present several experiments are being designed and hopefully will be operating in the next year or so. We will discuss an experiment based upon a neutrino capture reaction that is the inverse of the electron-capture radioactive decay of argon-37. The method depends upon exposing a large volume of a chlorine compound, removing the radioactive argon-37 and observing the characteristic decay in a small low-level counter.

Instrumentation and performance analysis of the New Mexico Department of Agriculture solar heated and cooled building. Final report  

DOE Green Energy (OSTI)

An instrumentation system was designed and installed on the New Mexico Department of Agriculture (NMDA) building to evaluate the performance of the solar system. The NMDA building is the first specifically designed solar heated and cooled building constructed in the United States. The solar system utilizes the flat plate collectors with liquid as the thermal transfer fluid, hot and cold storage tanks, and an absorption chiller. Over two years of operating experience now exists in regard to the NMDA building. Operation of the NMDA building heating, ventilation and air conditioning (HVAC) system involves three modes. The full heating mode utilizes the collected solar thermal energy for space heating. The full cooling mode utilizes the energy input from the solar collectors in driving the absorption chiller to provide space cooling. The intermediate mode requires heating during the morning hours and cooling during the afternoon. Cooling for the intermediate mode utilizes the cooling tower due to the low ambient relative humidity. The requirement of auxiliary energy is met with a gas fired boiler within the building. The instrumentation system installed on the NMDA building monitored solar insolation, 45 temperatures, 15 flow rates, the rate of electrical energy consumption, local meterology and the relative humidity. The data was recorded on a 15 minute time interval during daylight and every hour during the night.

Solar Neutrinos  

E-Print Network (OSTI)

Experimental work with solar neutrinos has illuminated the properties of neutrinos and tested models of how the sun produces its energy. Three experiments continue to take data, and at least seven are in various stages of planning or construction. In this review, the current experimental status is summarized, and future directions explored with a focus on the effects of a non-zero theta-13 and the interesting possibility of directly testing the luminosity constraint. Such a confrontation at the few-percent level would provide a prediction of the solar irradiance tens of thousands of years in the future for comparison with the present-day irradiance. A model-independent analysis of existing low-energy data shows good agreement between the neutrino and electromagnetic luminosities at the +/- 20 % level.

Solar neutrinos and the solar composition problem  

E-Print Network (OSTI)

Standard solar models (SSM) are facing nowadays a new puzzle: the solar composition problem. New determinations of solar metal abundances lead SSM calculations to conflict with helioseismological measurements, showing discrepancies that extend from the convection zone to the solar core and can not be easily assigned to deficiencies in the modelling of the solar convection zone. We present updated solar neutrino fluxes and uncertainties for two SSM with high (old) and low (new) solar metallicity determinations. The uncertainties in iron and carbon abundances are the largest contribution to the uncertainties of the solar neutrino fluxes. The uncertainty on the ^14N+p -> ^15O+g rate is the largest of the non-composition uncertainties to the CNO neutrino fluxes. We propose an independent method to help identify which SSM is the correct one. Present neutrino data can not distinguish the solar neutrino predictions of both models but ongoing measurements can help to solve the puzzle.

Chemically deposited Bi[sub 2]S[sub 3]-Cu[sub x]S solar control coatings  

SciTech Connect

Solar control characteristics are described for chemically deposited thin film coatings consisting of an initial layer of Bi[sub 2]S[sub 3] film of [approximately] 0.05 [mu]m thickness deposited at room temperature (25 C) for 45-76 min from baths containing bismuth nitrate, triethanolamine (TEA) and thioacetamide and a Cu[sub x]S thin film of 0.1-0.25 [mu]m thickness deposited either at room temperature, for 3-6 h, or at 50 C, for 1-2 h using baths consisting of copper(II) chloride, TEA, thioureau (TU), NaOH and NH[sub 3](aq). Air annealing of these films at 150 C for 30 min yield well-desired solar control characteristics: sheet resistance in a range which signifies a low thermal emittance; integrated transmittance of 15-32% in the visible region and 11-22% in the near-infrared region; integrated transmittance of [approximately]13-25% for solar radiation and a range of shades in reflected daylight. Using a mathematical model, the solar control performance of these coatings in a 6 mm sheet glass is predicted for an architectural window in a tropical location showing that solar radiation rejection of [approximately] 50% is obtainable for a integrated transmittance of 17%.

Solar collector  

DOE Patents (OSTI)

The field of this invention is solar collectors, and more particularly, the invention pertains to a flat plate collector that employs high performance thin films. The solar collector of this invention overcomes several problems in this field, such as excessive hardware, cost and reliability, and other prior art drawbacks outlined in the specification. In the preferred form, the apparatus features a substantially rigid planar frame (14). A thin film window (42) is bonded to one planar side of the frame. An absorber (24) of laminate construction is comprised of two thin film layers (24a, 24b) that are sealed perimetrically. The layers (24a, 24b) define a fluid-tight planar envelope (24c) of large surface area to volume through which a heat transfer fluid flows. Absorber (24) is bonded to the other planar side of the frame. The thin film construction of the absorber assures substantially full envelope wetting and thus good efficiency. The window and absorber films stress the frame adding to the overall strength of the collector.
