Energy-Exchange Project

Description: The purpose of the study was to determine what energy savings can be achieved by coordinating the resources and requirements of two facilities, the 26th Ward Water Pollution Control Plant (WPCP) and a housing development named Starrett City with its own total energy system. It was determined that three energy exchange options were economically and technically feasible. These include: the transfer of digester gas produced at the 26th Ward to the boilers at the Starrett City's total energy plant … more

Alternatives for reducing hot-water bills

Description: A two stage approach to reducing residential water heating bills is described. In Stage I, simple conservation measures were included to reduce the daily hot water energy consumption and the energy losses from the water tank. Once these savings are achieved, Stage II considers more costly options for further reducing the water heating bill. Four alternatives are considered in Stage II: gas water heaters; solar water heaters (two types); heat pump water heaters; and heat recovery from a heat pum… more

An automated tool for evaluating compliance and providing assistance with building energy standards during design

Description: In an effort to encourage the maximum cost-effective level of energy efficiency in new building design, energy-efficiency standards have become more location-specific and performance-based. As a result, standards often provide more than one path for ensuring and demonstrating that a design complies, but at the cost of increased complexity. In addition, the burden of remedying a noncompliant design rests on the designers' knowledge and experience, with only general guidance provided by the stand… more

Klamath County YMCA geothermal heating project environmental assessment

Description: The YMCA Geothermal Heating project proposes to obtain approximately 57% of the total facility energy usage through direct application of the Klamath Falls KGRA. This will be accomplished through the design and construction of a retrofit and injection system for the utilization of an existing 110/sup 0/F geothermal energy source at the project site. The existing 2016 foot well will be outfitted with a turbine pump with variable speed drive. The well head will be enclosed by a 10' x 10' building… more

Analysis and technology transfer report, 1989 and 1990

Description: The buildings sector used 29.6 quadrillion Btus (quads) of energy in 1989, or 36 percent of the total primary energy consumed in the United States. The major uses are for space heating and cooling, water heating, refrigeration, and lighting. Electricity is the dominant fuel, followed by natural gas, petroleum, and other fuels. Although there were dramatic improvements in energy efficiency in this sector from 1975 to 1985, in recent years energy use has grown rapidly. The large growth expected i… more

DSM pocket guidebook

Description: It has been estimated that if electricity were used more efficiently with commercially available end-use technologies, 24%--44% of the nation's current demand for electricity could be eliminated. Almost all major electric utilities in the west are investigating such demand-side management (DSM) opportunities. In some service territories, for example, improved efficiency could soon produce as much power as that from new coal-fired plants and produce it at a lower cost. Even utilities that curren… more

Comparison of two options for supplying geothermal energy to the Veterans Administration Medical Center at Marlin, Texas

Description: Two options for supplying geothermal energy to the Veterans Administration Medical Center (VAMC) at Marlin, Texas were compared. One option is to drill a new production well on the VAMC property, and the other is to construct a 6900-ft pipeline from an existing geothermal well to the VAMC. Technical, economic, regulatory, and institutional issues were examined during the comparison. It was concluded that neither option possesses any significant cost or regulatory advantage over the other. The n… more

Geothermal Project. Final report

Description: The project was designed to take 95/sup 0/F water from an existing well and process it through a heat exchanger carrying supply water for our boiler make up and domestic hot water systems. The temperature of this water runs from 55/sup 0/F to 65/sup 0/F. In operation it was possible to raise the temperature of this water an average of approximately 12/sup 0/F. The amount of energy captured was recorded and it was found that one can capture approximately 199 x 10/sup 6/ Btu/Mo. Using current ene… more

How many people actually see the price signal? Quantifying marketfailures in the end use of energy

Description: "Getting the price right" is a goal of many market-orientedenergy policies. However, there are situations where the consumer payingfor the energy is separate from the owner of the energy-using device.Economists call this a "principal agent problem". A team organised by theInternational Energy Agency examined seven end uses and one sector whereprincipal agent problems existed: refrigerators, water heating, spaceheating, vending machines, commercial HVAC, company cars, lighting, andfirms.
