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

DOE Patents [OSTI]

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

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

Parameterization of daily solar irradiance variability  

Science Journals Connector (OSTI)

The effects of solar systems operation can be compared only under very similar weather conditions. Diagnostics of the solar systems requires unequivocal determination of solar irradiation. Development of a method for precise identification of solar radiation day time profile is needed, as the methods used so far in the cloud cover determination are not satisfactory. The paper presents two optional methods, developed by the authors, for identification of the solar radiation profile. Advantages and disadvantages of the methods are also specified.

Optimization of building window system in Asian regions by analyzing solar heat gain and daylighting elements  

Science Journals Connector (OSTI)

This paper presents and optimizes the annual heating, cooling and lighting energy consumption associated with applying different types and properties of window systems in a building envelope. Through using building simulation modeling, various window properties such as U-value, solar heat gain coefficient (SHGC), and visible transmittance (Tvis) are evaluated with different window wall ratios (WWRs) and orientations in five typical Asian climates: Manila, Taipei, Shanghai, Seoul and Sapporo. By means of a regression analysis, simple charts for the relationship between window properties and building energy performance are presented as a function of U-value, SHGC, Tvis, WWR, solar aperture, effective aperture, and orientation. As a design guideline in selecting energy saving windows, an optimized window system for each climate is plotted in detailed charts and tables.

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.

The New York Times Headquarters Daylighting Mockup: Monitored Performance The New York Times Headquarters Daylighting Mockup: Monitored Performance of the Daylighting Control System Title The New York Times Headquarters Daylighting Mockup: Monitored Performance of the Daylighting Control System Publication Type Journal Article LBNL Report Number LBNL-56979 Year of Publication 2006 Authors Lee, Eleanor S., and Stephen E. Selkowitz Journal Energy & Buildings Volume 38 Pagination 914-929 Call Number LBNL-56979 Abstract A nine-month monitored field study of the performance of automated roller shades and daylighting controls was conducted in a 401 m2 unoccupied, furnished daylighting mockup. The mockup mimicked the southwest corner of a new 110 km2 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.

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

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.

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.

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.

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.

Evaluating daylighting potential and energy efficiency in a classroom building  

Science Journals Connector (OSTI)

In this paper we analyze the possibility of using daylight as the main source of light for learning and teaching activities in a classroom building of the Universidade Tecnolgica Federal do Paran in Curitiba Brazil. Beginning with a survey on light bulb and luminaire types used in the building and on the potential of daylighting in such environments six different classroom types with different solar orientations were selected for analysis. The research methods included the estimation of daylighting potential from obtained daylight coefficients (DCs) for periods of the year and sky conditions other than those of the onsite measurements; the evaluation of conformity of the lighting system to the Brazilian RTQ Code (Regulamento Tcnico de Qualidade) an energy consumption rating system aimed at reducing electric energy consumption in office buildings; the estimation of electric energy demand for a combined use of daylighting and lighting system; the proposal of an efficient lighting system; and cost assessment using payback analysis. Results suggest energy savings of up to 94% when integrating daylight with the artificial lighting system a payback within the range of 2260 months for a complete substitution of the existing lighting system for a more efficient one.

The potential of different artificial neural network (ANN) techniques in daily global solar radiation modeling based on meteorological data  

SciTech Connect (OSTI)

The main objective of present study is to predict daily global solar radiation (GSR) on a horizontal surface, based on meteorological variables, using different artificial neural network (ANN) techniques. Daily mean air temperature, relative humidity, sunshine hours, evaporation, and wind speed values between 2002 and 2006 for Dezful city in Iran (32 16'N, 48 25'E), are used in this study. In order to consider the effect of each meteorological variable on daily GSR prediction, six following combinations of input variables are considered: (I)Day of the year, daily mean air temperature and relative humidity as inputs and daily GSR as output. (II)Day of the year, daily mean air temperature and sunshine hours as inputs and daily GSR as output. (III)Day of the year, daily mean air temperature, relative humidity and sunshine hours as inputs and daily GSR as output. (IV)Day of the year, daily mean air temperature, relative humidity, sunshine hours and evaporation as inputs and daily GSR as output. (V)Day of the year, daily mean air temperature, relative humidity, sunshine hours and wind speed as inputs and daily GSR as output. (VI)Day of the year, daily mean air temperature, relative humidity, sunshine hours, evaporation and wind speed as inputs and daily GSR as output. Multi-layer perceptron (MLP) and radial basis function (RBF) neural networks are applied for daily GSR modeling based on six proposed combinations. The measured data between 2002 and 2005 are used to train the neural networks while the data for 214 days from 2006 are used as testing data. The comparison of obtained results from ANNs and different conventional GSR prediction (CGSRP) models shows very good improvements (i.e. the predicted values of best ANN model (MLP-V) has a mean absolute percentage error (MAPE) about 5.21% versus 10.02% for best CGSRP model (CGSRP 5)).

Forecasting of preprocessed daily solar radiation time series using neural networks  

SciTech Connect (OSTI)

In this paper, we present an application of Artificial Neural Networks (ANNs) in the renewable energy domain. We particularly look at the Multi-Layer Perceptron (MLP) network which has been the most used of ANNs architectures both in the renewable energy domain and in the time series forecasting. We have used a MLP and an ad hoc time series pre-processing to develop a methodology for the daily prediction of global solar radiation on a horizontal surface. First results are promising with nRMSE {proportional_to} 21% and RMSE {proportional_to} 3.59 MJ/m{sup 2}. The optimized MLP presents predictions similar to or even better than conventional and reference methods such as ARIMA techniques, Bayesian inference, Markov chains and k-Nearest-Neighbors. Moreover we found that the data pre-processing approach proposed can reduce significantly forecasting errors of about 6% compared to conventional prediction methods such as Markov chains or Bayesian inference. The simulator proposed has been obtained using 19 years of available data from the meteorological station of Ajaccio (Corsica Island, France, 41 55'N, 8 44'E, 4 m above mean sea level). The predicted whole methodology has been validated on a 1.175 kWc mono-Si PV power grid. Six prediction methods (ANN, clear sky model, combination..) allow to predict the best daily DC PV power production at horizon d + 1. The cumulated DC PV energy on a 6-months period shows a great agreement between simulated and measured data (R{sup 2} > 0.99 and nRMSE < 2%). (author)

Daylighting directory 6/1980  

SciTech Connect (OSTI)

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.

Design daylight availability for greenhouses using supplementary lighting  

Science Journals Connector (OSTI)

An analysis is presented of daylight availability data in terms of suitable design criteria for greenhouse supplementary lighting systems. Percentile exceedance values for the daily photosynthetically active radiation (PAR) integral are proposed as the relevant design criteria, and a method is presented for using these data to determine the target supplementary light level in a greenhouse. A large set of daily radiation data were analysed to generate percentile data for 201 locations in the USA varying in latitude from 18.4 to 71.3 and elevation from 1 to 2300m. Analyses were carried out to assess the dependence of these percentile data on site latitude and elevation, and a mathematical model was fitted to the data. Results indicate that percentile data vary negatively with latitude and positively with elevation in a manner that can be calculated using these two inputs and a percentile-related coefficient with a resulting r2 of 0.982. The strength of relationship is greatest for moderate and high percentiles, with a mean absolute error (MAE) of 2.0molm?2d?1 for percentiles of 70% and above. These results indicate that percentile exceedance data can be used as a basis for assimilative lighting system design, both for locations near areas where recorded data are available, and for locations where only latitude and elevation data are known.

Daylighting simulation: methods, algorithms, and resources  

SciTech Connect (OSTI)

This document presents work conducted as part of Subtask C, ''Daylighting Design Tools'', Subgroup C2, ''New Daylight Algorithms'', of the IEA SHC Task 21 and the ECBCS Program Annex 29 ''Daylight in Buildings''. The search for and collection of daylighting analysis methods and algorithms led to two important observations. First, there is a wide range of needs for different types of methods to produce a complete analysis tool. These include: Geometry; Light modeling; Characterization of the natural illumination resource; Materials and components properties, representations; and Usability issues (interfaces, interoperability, representation of analysis results, etc). Second, very advantageously, there have been rapid advances in many basic methods in these areas, due to other forces. They are in part driven by: The commercial computer graphics community (commerce, entertainment); The lighting industry; Architectural rendering and visualization for projects; and Academia: Course materials, research. This has led to a very rich set of information resources that have direct applicability to the small daylighting analysis community. Furthermore, much of this information is in fact available online. Because much of the information about methods and algorithms is now online, an innovative reporting strategy was used: the core formats are electronic, and used to produce a printed form only secondarily. The electronic forms include both online WWW pages and a downloadable .PDF file with the same appearance and content. Both electronic forms include live primary and indirect links to actual information sources on the WWW. In most cases, little additional commentary is provided regarding the information links or citations that are provided. This in turn allows the report to be very concise. The links are expected speak for themselves. The report consists of only about 10+ pages, with about 100+ primary links, but with potentially thousands of indirect links. For purposes of the printed version, a list of the links is explicitly provided. This document exists in HTML form at the URL address: http://eande.lbl.gov/Task21/dlalgorithms.html. An equivalent downloadable PDF version, also with live links, at the URL address: http://eande.lbl.gov/Task21/dlalgorithms.pdf. A printed report can be derived directly from either of the electronic versions by simply printing either of them. In addition to the live links in the electronic forms, all report forms, electronic and paper, also have explicitly listed link addresses so that they can be followed up or referenced manually.

It reduces the area threshold for skylight daylit zones from 10,000 square feet to 2,000 square feet. It maintains 15 foot ceiling height requirement and the exception for climate zones 6 through 8. Energy Impact Based on average national energy prices 1 of $0.99 per therm and $0.1032 per kWh, the net savings are calculated with EnergyPlus(tm) 2 from whole building energy savings that result from reduced lighting, and depending on climate zone, increased or decreased heating and cooling.

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

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.

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.

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.

Daylighting Requirements in the National Building Energy Codes Theyre Here!  

SciTech Connect (OSTI)

Requirements for the control of electric lighting in daylighted areas have historically been avoided in the national building energy codes. This is potentially a rich source of energy savings but as most lighting designers and architects know, daylighting design is not simple! The sheer complication of daylighting design makes crafting daylighting control requirements that could be applied generically in a national energy code a difficult task. However, that is currently changing. The Department of Energys (DOE) Building Energy Codes Program (BECP) managed by Pacific Northwest National Laboratory (PNNL) has been supporting the ANSI/ASHRAE/IESNA 90.1 committee in developing improvements to the 90.1 Standard. With subcontract support, the 90.1 Lighting Subcommittee has championed the incorporation of daylighting design and control requirements for the upcoming 2010 version of the nationally available ANSI/ASHRAE/IESNA Standard 90.1 for commercial building energy use.

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.

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.

The spring switch to Daylight Saving Time can be rough-especially for those of us who aren't morning people-but that extra time in the afternoon sun sure is nice! The change took a few people by surprise-this is only the third year that Daylight Saving Time started the second Sunday in March, rather than the first Sunday in April. The Energy Policy Act of 2005 changed the start and end dates of Daylight Saving Time in order to save energy, and DOE has found that it worked. The savings from the shift, while small percentage-wise, are enough to power about 122,000 average U.S. homes for a year. See the article in EERE

Chapter 27 - Why do we neglect the proof? Advantages without disadvantages: Solar Energy can give more comfortable, healthier homes and sunnier streets Why is passive solar design no daily practice all over the world?  

Science Journals Connector (OSTI)

Publisher Summary The Schiedam experience was followed by some more building plans in other towns. Still, today passive solar design in the Netherlands seldom or never is the basic design rule for new construction. The possibility of lower energy bills, less greenhouse gasses, more comfortable homes, and better streets still is greatly ignored in new building plans. Passive solar designs give no market place to extra products or to extra sell, only the final occupant gets a better product. The possibility of this better product (at no extra cost) obviously is not an incentive that is strong enough in most markets. Government should encourage this strongly if the greenhouse effect is taken seriously and when it is realized that fossil fuels in the society are used at a frightening high speed.

Acceptable Daily Intake (ADI)  

Science Journals Connector (OSTI)

Abstract The acceptable daily intake (ADI) is commonly defined as the maximum amount of a chemical to which a person can be exposed, on a daily basis over an extended period of time, usually without suffering a deleterious effect. It represents a daily intake level of a chemical in humans that is associated with minimal or no risk of adverse effects, and if the ingestion exceeds, this amount may cause toxic effects. It is a numerical estimate of daily oral exposure to the human population, including sensitive subgroups such as children, that is not likely to cause harmful effects during a lifetime. The ADI is expressed in milligrams of the chemical, as it appears in the food, per kilogram of body weight per day (mgkg?1day?1).

At what time of the day is the temperature coldest? Replies: In general, the hottest part of the day is late afternoon. The sun has passed its peak in the sky but still heats the Earth up until very late in the afternoon. The lowest temperatures are around dawn. Earth has had all night to get rid of the day's heat by radiating it into space. After sunrise, temperatures begin to climb. This can be changed by local storms, sea breezes or mountain breezes and even monsoon winds. Hope this helps. R. W. "Bob" Avakian Instructor Arts and Sciences/CRC Oklahoma State Univ.

Annual daylighting performance of a passive optical light shelf in sidelit  

Broader source: All U.S. Department of Energy (DOE) Office Webpages (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).

Acceleration of the matrix multiplication of Radiance three phase daylighting simulations with parallel computing on heterogeneous hardware of personal computer  

SciTech Connect (OSTI)

Building designers are increasingly relying on complex fenestration systems to reduce energy consumed for lighting and HVAC in low energy buildings. Radiance, a lighting simulation program, has been used to conduct daylighting simulations for complex fenestration systems. Depending on the configurations, the simulation can take hours or even days using a personal computer. This paper describes how to accelerate the matrix multiplication portion of a Radiance three-phase daylight simulation by conducting parallel computing on heterogeneous hardware of a personal computer. The algorithm was optimized and the computational part was implemented in parallel using OpenCL. The speed of new approach was evaluated using various daylighting simulation cases on a multicore central processing unit and a graphics processing unit. Based on the measurements and analysis of the time usage for the Radiance daylighting simulation, further speedups can be achieved by using fast I/O devices and storing the data in a binary format.

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

SciTech Connect (OSTI)

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.

Empirical assessment of a prismatic daylight-redirecting window film in a full-scale office testbed  

SciTech Connect (OSTI)

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-towall 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. The window film was found to result in perceptible levels of discomfort glare on clear sunny days from the most conservative view point in the rear of the room looking toward the window. Daylight illuminance levels at the rear of the room were significantly increased above the reference window condition, which was defined as the same glazed clerestory window but with an interior Venetian blind (slat angle set to the cut-off angle), for the equinox to winter solstice period on clear sunny days. For partly cloudy and overcast sky conditions, daylight levels were improved slightly. To reduce glare, the daylighting film was coupled with a diffusing film in an insulating glazing unit. The diffusing film retained the directionality of the redirected light spreading it within a small range of outgoing angles. This solution was found to reduce glare to imperceptible levels while retaining for the most part the illuminance levels achieved solely by the daylighting film.

Thermal and daylighting evaluation of the effect of varying aspect ratios in urban canyons in Curitiba, Brazil  

Science Journals Connector (OSTI)

Urbanization is commonly associated with densification which may lead to vertical growth or urban consolidation. The present study evaluates the daylighting potential as a function of urban morphology for the city of Curitiba ( 25 2 5 ? 5 0 ? ? S 46 1 6 ? 1 5 ? ? W ). It also presents a thermal analysis for a representative street axis orientation in this location showing indoor conditions within a test office for different aspect ratios. In Curitiba certain street axes were designated to allow densification (in the so-called structural sector of the city). As a consequence there is a great risk of urban canyons being formed as local legislation does not impose height restrictions to adjacent buildings. Daylight analysis was based on software simulations with LUZ DO SOL DLN ECOTECT and RADIANCE. Thermal analysis was carried out by means of computer simulations with the IDA ICEsoftware. It was verified that diagonal axial orientations relative to the north (rotated in 45) provide higher daylighting potentials to buildings located in urban canyons. With regard to the thermal effect of varying the aspect ratio in an east-west street axis results confirm daylighting simulations showing the interrelation between both comfort parameters.

Experimental analysis on a 1:2 scale model of the double light pipe, an innovative technological device for daylight transmission  

SciTech Connect (OSTI)

In this paper the authors present the double light pipe, an innovative technological device, designed as an evolution of a traditional light pipe, which distributes daylight to underground areas of a building, illuminating, at the same time, the passage areas thanks to a larger collector and a second transparent pipe attached to the first one. Unlike the traditional light pipe, thanks to this double illuminating function it can be located in the middle of a room, despite its encumbrance. In this paper the technological design of the double light pipe is presented and the results of an experimental analysis on a reduced scale (1:2) model are shown. Internal illuminance data over horizontal and vertical work-planes were measured in various sky conditions with or without direct solar radiation. Being this innovative device obtained by a light pipe integrated with a second pipe, it performs like a traditional light pipe for the final room and, at the same time, illuminates the intermediate room giving it uniform and high quality light, particularly indicated for wide plant areas, such as show-rooms or museums.

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

SciTech Connect (OSTI)

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.

Effect of daylight saving time on lighting energy use: A literature review  

Science Journals Connector (OSTI)

The principal reason for introducing (and extending) daylight saving time (DST) was, and still is, projected energy savings, particularly for electric lighting. This paper presents a literature review concerning the effects of DST on energy use. Simple estimates suggest a reduction in national electricity use of around 0.5%, as a result of residential lighting reduction. Several studies have demonstrated effects of this size based on more complex simulations or on measured data. However, there are just as many studies that suggest no effect, and some studies suggest overall energy penalties, particularly if gasoline consumption is accounted for. There is general consensus that DST does contribute to an evening reduction in peak demand for electricity, though this may be offset by an increase in the morning. Nevertheless, the basic patterns of energy use, and the energy efficiency of buildings and equipment have changed since many of these studies were conducted. Therefore, we recommend that future energy policy decisions regarding changes to DST be preceded by high-quality research based on detailed analysis of prevailing energy use, and behaviours and systems that affect energy use. This would be timely, given the extension to DST underway in North America in 2007.

Developing hourly weather data for locations having only daily weather data  

SciTech Connect (OSTI)

A methodology was developed to modify an hourly TMY weather tape to be representative of a location for which only average daily weather parameters were avilable. Typical hourly and daily variations in solar flux, and other parameters, were needed to properly exercise a computer model to predict the transient performance of a solar controlled greenhouse being designed for Riyadh, Saudi Arabia. The starting point was a TMY tape for Yuma, Arizona, since the design temperatures for summer and winter are nearly identical for Yuma and Riyadh. After comparing six of the most important weather variables, the hourly values on the Yuma tape were individually adjusted to give the same overall daily average conditions as existed in the long-term Riyadh data. Finally, a statistical analysis was used to confirm quantitatively that the daily variations between the long term average values for Riyadh and the modified TMY weather tape for Yuma matched satisfactorily.

Chapter 5 - Passive Utilization of Solar Energy in a Building  

Science Journals Connector (OSTI)

Abstract This chapter presents different passive solar technologies applied in buildings with a focus on technologies suitable for high-latitude countries. Direct and indirect solar gain systems are presented and described in detail. Examples of traditional and modern passive solar solutions are analyzed. Special attention is given to buffer spaces and different glazing technologies; their application depending on climatic conditions is analyzed, and some recommendations are given. Implementation of transparent insulation (TI) in the building envelope is considered. TI is transparent for solar radiation and is characterized by relatively high thermal resistance. Some examples of TI practical applications are presented, including their use for daylighting purposes. The idea of integrating phase-change materials (PCMs) into building structures is considered. Their storage role, high heat capacity, as well as cooling and heating functions are explained. Different forms of PCM integration technologies are presented.

Combination fence and solar heater for swimming pools  

SciTech Connect (OSTI)

A combination fence and solar heater for swimming pools comprises a fence shaped for extending about the periphery of the pool to restrict ingress and egress therefrom. A tubular heat exchanger is formed in at least one section of the fence, includes an exterior surface adapted to absorb solar energy, and communicates with the water in the swimming pool. The number of heat exchanger fence sections can be varied in accordance with the climate in which the pool is located. A pump flows the water in the swimming pool through the heat exchanger fence sections during daylight hours, thereby simultaneously heating the water in the pool, and providing an attractive and protective safety barrier about the swimming pool.

Solar cooling in Madrid: Available solar energy  

SciTech Connect (OSTI)

This paper analyzes the behaviour of an absorption chiller lithium bromide installation fed by a field of flat-plate solar collectors and condensed by swimming pool water. A method of calculation in a variable regime is developed in terms of the obtained experimental results. Starting from the meteorological variables of a clear summer day and from the project data (collector normalization curve, collector and installation mass), the minimum solar radiation level necessary to initiate the process, I[sub min], and the instantaneous available solar energy, Q[sub u] + W[sub 1] is determined. The solar radiation threshold, I[sub min], necessary to obtain the process temperature, t[sub ave], in each instant, is obtained by adding to the corrected Klein radiation threshold, I[sub k,c], the heat capacity effects of the collector, HCE[sub CO], and of the installation, HCE[sub ins], as well as the losses of heat of the pipes to the surroundings, Q[sub 1]. The instantaneous available solar energy, available useful heat, in addition to the wind collector losses to the surroundings, Q[sub u] + W[sub 1], is the difference, in each instant, between the radiation, I[sub g1T], and the radiation threshold, I[sub min].The integration during the day of the instantaneous available solar energy allows us to calculate the daily available function, H[sub T]. The value of H[sub T], measured in the swimming-pool water condensation installation reached 6.92 MJ/(m[sup 2] day ). The calculated values of H[sub T] for a conventional installation condensed by tower water, or air, have been 6.35 and 0.56 MJ/(m[sup 2] day). respectively.

Calorimetric determination of the solar heat gain coefficient g with steady-state laboratory measurements  

Science Journals Connector (OSTI)

Abstract The paper describes procedures for the direct calorimetric measurement of the solar heat gain coefficient g in detail. g is also called SHGC, solar factor, g-value or total solar energy transmittance TSET. All these terms are used synonymously in this document although there are some differences in the details of the definitions of these properties (e.g. different reference wind conditions or reference solar spectra). The document aims to summarize more than 25 years of experience in g-value testing at Fraunhofer ISE, Freiburg, Germany, which includes many different transparent and translucent building materials ranging from transparent insulation materials to daylighting and solar control systems and active solar energy harvesting facade components like building-integrated PV systems (BIPV) or building-integrated solar thermal collectors (BIST). The document focuses on methods for the calorimetric measurement of g under steady-state laboratory conditions. Transient outdoor measurements are beyond the scope of this paper. It also describes the corresponding error analysis and methods to correct experimentally determined values gexp to reference conditions, if it is not possible to reproduce the reference boundary conditions exactly in the laboratory.

Solar Resource Assessment for Sri Lanka and Maldives  

SciTech Connect (OSTI)

The countries of Sri Lanka and the Maldives lie within the equatorial belt, a region where substantial solar energy resources exist throughout much of the year in adequate quantities for many applications, including solar water heating, solar electricity, and desalination. The extent of solar resources in Sri Lanka has been estimated in the past based on a study of the daily total direct sunshine hours recorded at a number of weather and agricultural stations throughout the country. These data have been applied to the well-known Angstrom relationship in order to obtain an estimate of the distribution of monthly average daily total solar resources at these stations. This study is an effort in improve on these estimates in two ways: (1) to apply a gridded cloud cover database at a 40-km resolution to produce updated monthly average daily total estimates of all solar resources (global horizontal, DNI, and diffuse) for the country, and (2) to input hourly or three-hourly cloud cover observations made at nine weather stations in Sri Lanka and two in the Maldives into a solar model that produces estimates of hourly solar radiation values of the direct normal, global, and diffuse resource covering the length of the observational period. Details and results of these studies are summarized in this report.

A Technical and Economic Potential of Solar Energy Application with Feed-in Tariff Policy in Indonesia  

Science Journals Connector (OSTI)

Abstract This paper presents a technical and economic potential of Solar Energy Application in Indonesia. Indonesia consists of thousands islands. Meanwhile, according to the latest data from the Department of Energy and Mineral Resources in 2012, Indonesia's electrification ratio is only around 74%. Renewable energy especially solar energy is one of the most potential energy sources as Indonesia lies in the equator line where the daylight is abundant and available throughout the year. The solar energy technologys is also eco-friendly and its application has the potential to reduce the greenhouse gas emission. A review of solar energy potential in Indonesia based on the solar resource data is presented. Estimation of solar resource in Indonesia was done using solar radiation data from NASA Surface Meteorology and Solar Energy (SSE). Retscreen software was used for all of the calculation in the study. It is found that the proposed system can generate electricity annually vary from 0.46 GWh/year in Denpasar to 217 GWh/year in Pontianak. This paper also calculates the economic viability through pre-tax IRR and simple payback indicator. It was observed that the highest IRR was observed in Makassar and the lowest IRR was observed in Banjarmasin. Meanwhile, it can be observed that Makassar got the shortest payback period for 11 years and Banjarmasin got the longest payback period of 17.6 years. From the side of environmental impact, the proposed system can reduce the GHG emission up to 243252 tons per year in particular selected location.

A Modified Efficiency Equation of Solar Collectors  

Science Journals Connector (OSTI)

Abstract This paper describes the derivation of a modified equation for solar collector efficiency that is expressed using the heating load term instead of the inlet fluid temperature term from the currently used linear collector efficiency equation. The parameters in the modified equation are estimated using test data measured for 14 days. In evaluation of the equation's validity, the calculated daily collector efficiency agrees well with the measured daily collector efficiency, with a correlation coefficient of 0.9110. The equation is also be expressed in another form by including the term for the shape of the hot water storage tank in the solar heating system. Collector efficiencies with parametric changes are calculated with the estimated parameters and compared with different global solar irradiance on solar collectors, daily average ambient temperature and heating loads per collector area. It would be necessary to estimate the parameters for better performance of the efficiency equation with more data from long-term system simulations at various operating conditions.

Optimization of solar flat collector inclination  

Science Journals Connector (OSTI)

Solar collectors need to be inclined at the optimum angle to maximize the receiving energy. In spite of many theoretical and experimental investigations on optimization of solar collector inclination, there is an inconsistency in presented results. In this paper, solar global radiation on a horizontal surface was estimated using a mathematical model and the results were compared with the recorded data from the Zahedan city meteorological station. Total received solar energy by a flat inclined collector was determined in a certain day, and searching for the angle which has the maximum incident energy was the general procedure in determination of daily optimum tilt angle. In case of operational limitation for daily tilt adjustment, this procedure is repeated for other specific period of time and monthly, seasonal, semi-annual and annual optimum tilt angles were determined. A MATLAB-based code is used to calculate the daily optimum tilt angle. The results were in good agreement with the obtained data of a new constructed device. Finally, in the case of stationary devices, some recommendations were presented with respect to their typical application.

Solar collector  

SciTech Connect (OSTI)

A solar collector is disclosed which is tiltable about a horizontal axis so as to vary the angle at which solar radiation is received by the collector. The solar collector, which uses air as the heat transfer medium, has connected to it a pair of fixed, well-insulated air transfer passages which penetrate through into the interior of the collector at the lateral sides thereof aligned with the horizontal axis about which the collector is pivoted. The air transfer passages are insulated and are gasketed to the sides of the collector so as to improve the efficiency of the solar energy system by avoiding losses of heat from the heat transfer fluid during transfer of the fluid from the collector to the space being heated.

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.

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: monthly and annual average direct normal (DNI), global horizontal  

Open Energy Info (EERE)

South America from NREL South America from NREL Dataset Summary Description (Abstract): Monthly Average Solar Resource for horizontal and tilted flat-plates, and 2-axis tracking concentrating collectors. (Purpose): Provide information on the solar resource potential for the data domain. The insolation values represent the average solar energy available to solar collectors. (Supplemental Information): These data provide monthly average and annual average daily total solar resource averaged over surface cells of approximately 40 km by 40 km in size. The solar resource value is represented as watt-hours per square meter per day for each month. The data were developed from NREL's Climatological Solar Radiation (CSR) Model. This model uses information on cloud cover, atmospheric water vapor and trace gases, and the amount of aerosols in the atmosphere to calculate the monthly average daily total insolation (sun and sky) falling on a horizontal surface. Existing ground measurement stations are used to validate the data where possible. The modeled values are accurate to approximately 10% of a true measured value within the grid cell due to the uncertainties associated with meteorological input to the model. The local cloud cover can vary significantly even within a single grid cell as a result of terrain effects and other microclimate influences. Furthermore, the uncertainty of the modeled estimates increase with distance from reliable measurement sources and with the complexity of the terrain.

Optimum tilt angle and orientation for solar collectors in Syria  

Science Journals Connector (OSTI)

One of the important parameters that affect the performance of a solar collector is its tilt angle with the horizon. This is because of the variation of tilt angle changes the amount of solar radiation reaching the collector surface. A mathematical model was used for estimating the solar radiation on a tilted surface, and to determine the optimum tilt angle and orientation (surface azimuth angle) for the solar collector in the main Syrian zones, on a daily basis, as well as for a specific period. The optimum angle was computed by searching for the values for which the radiation on the collector surface is a maximum for a particular day or a specific period. The results reveal that changing the tilt angle 12 times in a year (i.e. using the monthly optimum tilt angle) maintains approximately the total amount of solar radiation near the maximum value that is found by changing the tilt angle daily to its optimum value. This achieves a yearly gain in solar radiation of approximately 30% more than the case of a solar collector fixed on a horizontal surface.

Solar collector  

SciTech Connect (OSTI)

The disclosure is a solar collector consisting of glass rods enclosed in a housing and mounted vertically on a roof or other elevated place to gather solar rays. The collector is fixed, with no tracking device or other moving parts. The glass rods are 6 mm or smaller in diameter, and there can be several thousand, depending on the sizes of the rods and collector. The upper ends of the rods are inclined at an angle of thirty degrees from horizontal, with the inclined surfaces occupying a plane which faces south so as to obtain maximum exposure to the winter sun. Solar rays striking the inclined ends of the rods are refracted into the rods. The rays travel down through the rods, with a predominantly parallel path of propagation being established by repeated reflections off the inside walls of the rods. The rays are emitted from the lower perpendicular ends of the rods as parallel rays of incoherent light which are directed into beam concentrators.

Geometry of tower-type solar electric station heliostat field  

SciTech Connect (OSTI)

A general method is presented for calculating the angular positions of an arbitrary heliostat at an arbitrary position in a heliostat field surrounding a tower-type solar electric station as a function of solar position. A system of angular coordinates is used which rotates with the solar azimuth direction around the collecting tower, resulting in an expression for the proper orientation of heliostat mirrors that is independent of local latitude, solar declination and time of day. The lines on the horizontal plane of the heliostat field characterized by the same values of the angles governing the horizontal inclination of the corresponding heliostat for a given solar elevation form two families of hyperbolas with vertexes facing the center of the field. Such isoline drawings constructed from the calculations may be used to determine the limiting values of the heliostat angles during the daily and seasonal course of operation of the heliostat facility.

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.

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.

Do Diurnal Aerosol Changes Affect Daily Average Radiative Forcing?  

SciTech Connect (OSTI)

Strong diurnal variability of aerosol has been observed frequently for many urban/industrial regions. How this variability may alter the direct aerosol radiative forcing (DARF), however, is largely unknown. To quantify changes in the time-averaged DARF, we perform an assessment of 29 days of high temporal resolution ground-based data collected during the Two-Column Aerosol Project (TCAP) on Cape Cod, which is downwind of metropolitan areas. We demonstrate that strong diurnal changes of aerosol loading (about 20% on average) have a negligible impact on the 24-h average DARF, when daily averaged optical properties are used to find this quantity. However, when there is a sparse temporal sampling of aerosol properties, which may preclude the calculation of daily averaged optical properties, large errors (up to 100%) in the computed DARF may occur. We describe a simple way of reducing these errors, which suggests the minimal temporal sampling needed to accurately find the forcing.

Yearly-averaged daily usefulness efficiency of heliostat surfaces  

SciTech Connect (OSTI)

An analytical expression for estimating the instantaneous usefulness efficiency of a heliostat surface is obtained. A systematic procedure is then introduced to calculate the usefulness efficiency even when overlapping of blocking and shadowing on a heliostat surface exist. For possible estimation of the reflected energy from a given field, the local yearly-averaged daily usefulness efficiency is calculated. This efficiency is found to depend on site latitude angle, radial distance from the tower measured in tower heights, heliostat position azimuth angle and the radial spacing between heliostats. Charts for the local yearly-averaged daily usefulness efficiency are presented for {phi} = 0, 15, 30, and 45 N. These charts can be used in calculating the reflected radiation from a given cell. Utilization of these charts is demonstrated.

A solar energy water heating unit is provided which heats water from a swimming pool by passing the water through a series of spiral hoses mounted on a supporting surface. The supporting surface is mounted on a platform raised from the ground and is cone-shaped to allow for at least a portion of each hose line to be exposed to the sun at all times of the day. The spiral hose lines are mounted in spiral grooves provided on the supporting surface. A pump pumps the water from the swimming pool to the inlet of the hose lines, which inlet is adjacent the lowermost edge of the supporting surface so that the water is always pumped upwardly to the outlet end of the hose lines adjacent the apex of the supporting surface.

IEP - Water-Energy Interface: Total Maximum Daily Load Page  

Broader source: All U.S. Department of Energy (DOE) Office Webpages (Extended Search)

Total Maximum Daily Loads (TMDLs) Total Maximum Daily Loads (TMDLs) The overall goal of the Clean Water Act is to "restore and maintain the chemical, physical, and biological integrity of the Nation’s waters." In 1999, EPA proposed changes to Section 303(d), to establish Total Maximum Daily Loads (TMDLs) for watersheds that do not meet this goal. The TMDL is the highest amount of a given pollutant that is permissible in that body of water over a given period of time. TMDLs include both waste load allocation (WLA) for point sources and load allocations for non-point sources. In Appalachia, acid mine drainage (AMD) is the single most damaging non-point source. There is also particular concern of the atmospheric deposition of airborne sulfur, nitrogen, and mercury compounds. States are currently in the process of developing comprehensive lists of impaired waters and establishing TMDLs for those waters. EPA has recently proposed a final rule that will require states to develop TMDLs and implement plans for improving water quality within the next 10 years. Under the new rule, TMDL credits could be traded within a watershed.

Assessment of solar energy as an alternative energy source for the Republic of Panama  

SciTech Connect (OSTI)

A number of different applications of solar energy were selected for an assessment of the potential solar use in the industrial, commercial and agricultural sectors of the Panamanian economy. Various solar technologies are taken into consideration with the solar water heating for industrial, commercial and institutional uses being designated as preferable for a large scale implementation. The anticipated energy saving by using solar energy to provide 50% of the energy contribution for water heating for selected applications is presented. Data showing the cost of materials required for such a solar energy contribution are given. Data for the monthly average of the daily total insolation and the reliability of these data are discussed. Finally, the expected impact of solar energy use in the Republic of Panama is discussed.

Monthly average daily irradiation on surfaces tilted towards the equator and also inclined at various azimuth angles are estimated for two locations in Lesotho and the results are presented. The isotropic model suggested by Liu and Jordan (Trans. of Ashrae, 526, 1962) along with the modified equation of Klein (Solar Energy, 19, 4, 1977) are employed for the estimation purposes. Surface orientations are selected at three inclinations for six different azimuth angles. Conclusions are reached for optimum tilt and orientation for summer, winter and annual collection. Total annual radiation values are computed for all the slopes and orientations.

Photovoltaic solar concentrator module  

SciTech Connect (OSTI)

This invention consists of a planar photovoltaic concentrator module for producing an electrical signal from incident solar radiation which includes an electrically insulating housing having a front wall, an opposing back wall and a hollow interior. A solar cell having electrical terminals is positioned within the interior of the housing. A planar conductor is connected with a terminal of the solar cell of the same polarity. A lens forming the front wall of the housing is operable to direct solar radiation incident to the lens into the interior of the housing. A refractive optical element in contact with the solar cell and facing the lens receives the solar radiation directed into the interior of the housing by the lens and directs the solar radiation to the solar cell to cause the solar cell to generate an electrical signal. An electrically conductive planar member is positioned in the housing to rest on the housing back wall in supporting relation with the solar cell terminal of opposite polarity. The planar member is operable to dissipate heat radiated by the solar cell as the solar cell generates an electrical signal and further forms a solar cell conductor connected with the solar cell terminal to permit the electrical signal generated by the solar cell to be measured between the planar member and the conductor.

Solar buildings. Overview: The Solar Buildings Program  

SciTech Connect (OSTI)

Buildings account for more than one third of the energy used in the United States each year, consuming vast amounts of electricity, natural gas, and fuel oil. Given this level of consumption, the buildings sector is rife with opportunity for alternative energy technologies. The US Department of Energy`s Solar Buildings Program was established to take advantage of this opportunity. The Solar Buildings Program is engaged in research, development, and deployment on solar thermal technologies, which use solar energy to produce heat. The Program focuses on technologies that have the potential to produce economically competitive energy for the buildings sector.

High-resolution maps of solar collector performance using a climatological solar radiation model  

SciTech Connect (OSTI)

This paper will present a new methodology for producing estimates of the monthly and annual average performance of different types of flat-plate and concentrating solar collectors. The estimates are made on a uniform spatial grid with 40 km resolution. These estimates should be highly useful both to create maps to facilitate visualization of the solar resource, and as the basic data behind analytical studies of solar resources, deployment scenarios, CO{sub 2} mitigation strategies, and economic assessments. Their initial use of this methodology will be in the continental United States, where supporting data is available to evaluate the model outputs. In future years the authors hope to utilize this technique world-wide, especially in areas where the surface data are lacking. The National Renewable Energy Laboratory (NREL, Golden, CO) has developed the Climatological Solar Radiation (CSR) model to estimate climatological averages of daily-total solar radiation at a 40 km spatial resolution. The CSR model is operational and has been usefully applied to the US as well as several international areas. The model uses, as input, monthly climatological mean values of cloud cover, precipitable water vapor, aerosol optical depth, surface albedo, and total column ozone. These input parameters are available from various sources such as NASA and NCDC (National Climatic Data Center). The outputs from the original version of CSR are monthly mean daily total values of Global Horizontal, Direct Normal, and Diffuse radiation. Their latest revision of the model allows them to calculate the monthly mean output for the various collector types such as tilted flat-plate surfaces, one- and two-axis flat-plate collectors, and concentrating collectors.

Concentrating Solar Power: Best Practices Handbook for the Collection and Use of Solar Resource Data (CSP)  

SciTech Connect (OSTI)

As the world looks for low-carbon sources of energy, solar power stands out as the most abundant energy resource. Harnessing this energy is the challenge for this century. Photovoltaics and concentrating solar power (CSP) are two primary forms of electricity generation using sunlight. These use different technologies, collect different fractions of the solar resource, and have different siting and production capabilities. Although PV systems are most often deployed as distributed generation sources, CSP systems favor large, centrally located systems. Accordingly, large CSP systems require a substantial investment, sometimes exceeding $1 billion in construction costs. Before such a project is undertaken, the best possible information about the quality and reliability of the fuel source must be made available. That is, project developers need to have reliable data about the solar resource available at specific locations to predict the daily and annual performance of a proposed CSP plant. Without these data, no financial analysis is possible. This handbook presents detailed information about solar resource data and the resulting data products needed for each stage of the project.

Solar energy conversion apparatus  

SciTech Connect (OSTI)

Apparatus is disclosed for converting solar energy to more useful forms, I.E., thermal and electrical energy. Such apparatus includes a photoelectric transducer (E.G., an array of photovoltaic cells), means for concentrating solar energy on the transducer, and means for circulating a liquid between the transducer and the solar energy concentrator. The spectral properties of the liquid are such that the liquid functions as a bandpass filter, transmitting solar energy to which the transducer is responsive and absorbing solar energy to which the transducer is non-responsive. The transmitted solar energy is converted to electrical energy by the transducer, and the absorbed solar energy is converted to heat by the liquid. Preferably, the liquid is circulated through a container which, in the vicinity of the transducer, is constructed so as to provide optical gain to the system and to integrate incident solar energy for the purpose of eliminating ''hot spots'' which could overheat, and thereby damage, the transducer.

Final Test and Evaluation Results from the Solar Two Project  

SciTech Connect (OSTI)

Solar Two was a collaborative, cost-shared project between 11 U. S. industry and utility partners and the U. S. Department of Energy to validate molten-salt power tower technology. The Solar Two plant, located east of Barstow, CA, comprised 1926 heliostats, a receiver, a thermal storage system, a steam generation system, and steam-turbine power block. Molten nitrate salt was used as the heat transfer fluid and storage media. The steam generator powered a 10-MWe (megawatt electric), conventional Rankine cycle turbine. Solar Two operated from June 1996 to April 1999. The major objective of the test and evaluation phase of the project was to validate the technical characteristics of a molten salt power tower. This report describes the significant results from the test and evaluation activities, the operating experience of each major system, and overall plant performance. Tests were conducted to measure the power output (MW) of the each major system, the efficiencies of the heliostat, receiver, thermal storage, and electric power generation systems and the daily energy collected, daily thermal-to-electric conversion, and daily parasitic energy consumption. Also included are detailed test and evaluation reports.

Photovoltaic solar concentrator  

DOE Patents [OSTI]

A photovoltaic solar concentrator is disclosed with one or more transverse-junction solar cells (also termed point contact solar cells) and a lens located above each solar cell to concentrate sunlight onto the solar cell to generate electricity. Piezoelectric actuators tilt or translate each lens to track the sun using a feedback-control circuit which senses the electricity generated by one or more of the solar cells. The piezoelectric actuators can be coupled through a displacement-multiplier linkage to provide an increased range of movement of each lens. Each lens in the solar concentrator can be supported on a frame (also termed a tilt plate) having three legs, with the movement of the legs being controlled by the piezoelectric actuators.
