Stirling total energy systems study. Final report, May 15, 1976--June 13, 1977

Description: The application of Stirling cycle prime movers to total energy power generation systems was investigated. Electrical, heating, and cooling demand profiles for a typical residential complex, hospital, and office building were studied, and alternative Stirling total energy systems were conceptualized for each site. These were analyzed in detail and contrasted with purchased-power systems for these sites to determine fuel-energy savings and investment attractiveness. The residential complex and ho… more

Engineering considerations of the advanced free electron laser facility

Description: The Advanced Free-Electron Laser (AFEL) is being built at Los Alamos inside a large laboratory building. In addition to cost and available space considerations, several engineering issues affected the design of the AFEL and its facility. The 1300-MHz, 20-MeV electron linac required extensive radiation shielding and a short rf-waveguide run. Free-Electron Lasers (FEL) and photocathode-drive laser optics required a clean, constant temperature environment. New environmental, health, and safety (ES… more

Form-stable crystalline polymer pellets for thermal energy storage. Phase 1

Description: The objective of this project was to develop a form-stable, crystalline polymer pellet TES bed material, useful in the 120 to 140/sup 0/C temperature range suitable for solar absorption air conditioning applications. This objective was achieved with a Si-O-Si crosslinked HDPE pellet material, demonstrated to have a high heat of fusion value (46 cal/g, approximately 98% of the HDPE's heat of fusion value prior to crosslinking). Further, on melt/freeze cycling of these TES pellets through 400 cyc… more

Studies of evaporative and conventional cooling of an energy conserving California house

Description: For cooling a Sacramento, California home, (1) higher thermostat settings, (2) insulation (3) ''solar control'' window shades, and (4) the use of an evaporative cooler in the place of a vapor compression cycle air conditioner are studied. A computer program TWOZONE is used to evaluate the effect on energy consumption and peak power. It is calculated that the peak cooling load can be reduced by a factor of 5 or more and the total energy by a factor of 20 or more.

Microcomputers for energy conservation in homes and other small buildings

Description: Low cost microcomputers and related microelectric devices now make it practical to apply additional energy conserving control strategies in single-family homes and other small buildings. These conservation measures can make significant contributions toward attainment of national energy conservation objectives. Applications in space conditioning (heating, cooling, ventilation), lighting, electric demand limiting, metering of energy in various forms and for status displays are outlined. Examples … more

Monitoring of the performance of a solar heated and cooled apartment building. Final report

Description: An all-electric apartment building in Texas was retrofitted for solar heating and cooling and hot water. The system consists of an array of 1280 square feet of Northrup concentrating tracking collectors, a 5000-gallon hot water storage vessel, a 500-gallon chilled water storage vessel, a 25-ton Arkla Industries absorption chiller, and a two-pipe hydronic air conditioning system. The solar air conditioning equipment is installed in parallel with the existing conventional electric heating and coo… more

Geothermal energy for American Samoa

Description: The geothermal commercialization potential in American Samoa was investigated. With geothermal energy harnessed in American Samoa, a myriad of possibilities would arise. Existing residential and business consumers would benefit from reduced electricity costs. The tuna canneries, demanding about 76% of the island's process heat requirements, may be able to use process heat from a geothermal source. Potential new industries include health spas, aquaculture, wood products, large domestic and trans… more

Geothermal development of the Madison group aquifer: a case study

Description: A geothermal well has been drilled at the St. Mary's Hospital in Pierre, South Dakota. The well is 2176 feet deep and artesian flows 375 gpm at 106/sup 0/F. The well is producing fluids from the Mississippian Madison Group, a sequence of carbonate rocks deposited over several western states. The project was funded to demonstrate the goethermal potential of this widespread aquifer. This case study describes the development of the project through geology, drilling, stimulation, and testing.

Commercialization survey for the Department of Energy's Solar Building Demonstration Program

Description: The National Solar Heating and Cooling Program for commercial buildings has been in place for approximately seven years. In the drive to create a viable solar heating and cooling industry in an unprecedented short period of time (5 years), mistakes have been made but many lessons have been learned. The biggest mistake was the belief that the time was ripe for a demonstration program instead of an applications test program. This has led to the following: forcing of the technology before it was f… more

Approaches for Acquiring Energy Savings in Commercial Sector Buildings : Environmental Assessment.

Description: Bonneville has carefully considered the potential environmental impacts associated with installation of currently known Energy- efficient Conservation Measures (ECMs) in new and existing commercial buildings, and has implemented specific requirements to minimize those impacts. These Commercial Environmental Requirements would apply to the three proposed conservation approaches outlined in this environmental assessment. The cumulative energy savings from these proposed commercial programs will h… more

Assessment of a geothermal application at Tucson, Arizona

Description: This study assessed the potential of using a geothermal energy source thought to underlie a large computer company's new facility near Tucson, Arizona. This energy source would be used with existing technology to meet the air conditioning and heating requirements of the proposed one million-square-foot expansion that would double the size of the facility. Cost data generated in this study could also be used to make economic determinations of retrofitting the existing, electrically driven centri… more

Monitoring and evaluation of replacing low-efficiency air conditioners with high-efficiency air conditioners in single-family detached houses in Austin, Texas

Description: The US DOE initiated this project to evaluate the performance of an air conditioner retrofit program in Austin, Texas. The City's Austin's Resource Management Department pursued this project to quantify the retrofit effect of replacing low-efficiency air conditioners with high-efficiency air conditioners in single-family detached homes. If successfully implemented, this retrofit program could help defer construction of a new power plant which is a major goal of this department. The project comp… more

Timonium Elementary School solar energy heating and cooling augmentation experiment. Final engineering report: executive summary (ER-8877)

Description: This report covers a two-year and seven-month solar space heating and cooling experiment conducted at the Timonium Elementary School, Timonium, Maryland. The system was designed to provide a minimum of 50% of the energy required during the heating season and to determine the feasibility of using solar energy to power absorption-type chillers for cooling. The area to be heated or cooled totaled approximately 8500 square feet of the center wing of the school. To accomplish this a system containin… more

EnergyPlus Analysis Capabilities for Use in California Building Energy Efficiency Standards Development and Compliance Calculations

Description: California has been using DOE-2 as the main building energy analysis tool in the development of building energy efficiency standards (Title 24) and the code compliance calculations. However, DOE-2.1E is a mature program that is no longer supported by LBNL on contract to the USDOE, or by any other public or private entity. With no more significant updates in the modeling capabilities of DOE-2.1E during recent years, DOE-2.1E lacks the ability to model, with the necessary accuracy, a number of bu… more
