Impacts of the national energy programme on solar economics

Description: The National Energy Plan (NEP) sets as a goal the use of solar energy in two and a half million homes in 1985. A key provision of the NEP (as well as congressional alternatives) provides for the subsidization of solar equipment. The extent to which these subsidies (income tax credits) might offset the impact of continued energy-price control is examined. Regional prices and availability of conventional energy sources (oil, gas, and electricity) were compiled to obtain a current and consistent s… more

Economic analysis of the integrated heating and cooling potential of a residential passive-solar water wall design

Description: The heating potential of residential water wall designs has been analyzed for many years. Because this past work has been confined strictly to heating potential, it has understated the true energy savings potential of water walls. Preliminary performance estimates for the heating and cooling potential of water walls have recently been made available. These estimates include the Btu displacement that is attributable to a 300-square foot water wall design in a 1200-square foot residence. The desi… more

Value engineering as applied at the Savannah River Site for environmental restoration projects

Description: Value Engineering (VE) has been defined as the organized study of functions which satisfy the user's needs at the lowest life cycle costs through applied creativity. VE was established in the World War II era when Mr. Lawrence Miles formed the concept of intentionally substituting materials to perform the function of more expensive standard materials. Since that time, VE has spread throughout the Department of Defense procurement agencies, and has in recent times been applied to almost every go… more

Model of penetration of coal boilers and cogeneration in the paper industry

Description: A model has been developed to forecast the penetration of coal boilers and cogeneration of electricity in the paper industry. Given the demand for energy services (process steam and electricity) by the paper industry, the Penetration Model forecasts the demand for purchased fuel and electricity. The model splits the demand for energy service between energy carriers (coal, fuel oil/natural gas, bark, and spent liquor) on the basis of the installed capacity of 16 types of boilers (combinations of… more

Impact of common completion and workover activities on the effective costs of geothermal wells

Description: The impacts of completion practices on production and maintenance costs are considered. To evaluate alternative completion and workover technologies, a simple model has been developed that compares total well cost to total production or injection. The model is discussed briefly and results from its application to different completion and workover strategies are emphasized. The model development project had three aspects: (1) the establishment of a data base for the cost and effectiveness of var… more

Life Cost Based FMEA Manual: A Step by Step Guide to Carrying Out a Cost-based Failure Modes and Effects Analysis

Description: Failure occurs when one or more of the intended functions of a product are no longer fulfilled to the customer's satisfaction. The most critical product failures are those that escape design reviews and in-house quality inspection and are found by the customer. The product may work for a while until its performance degrades to an unacceptable level or it may have not worked even before customer took possession of the product. The end results of failures which may lead to unsafe conditions or ma… more

Thermal and cost goal analysis for passive solar heating designs

Description: Economic methodologies developed over the past several years for the design of residential solar systems have been based on life cycle cost (LCC) minimization. Because of uncertainties involving future economic conditions and the varied decision making processes of home designers, builders, and owners, LCC design approaches are not always appropriate. To deal with some of the constraints that enter the design process, and to narrow the number of variables to those that do not depend on future e… more

Energy performance standards: a look at the economic issues

Description: To determine the best level at which to set designed energy-consumption standards for buildings, economic efficiency based on prior determination of energy efficiency was chosen as the decision criterion. Life-cycle-cost minimization was identified as the best method of assessing tradeoffs between capital investment and fuel consumption in buildings, but there are several important parameters whose effect on the results must be carefully considered. The discount rate used to calculate the net p… more
