Commercial building systems analysis. Final report, January 1988-July 1989
The report describes the methodology used for conducting an economic analysis of Gas Heat Pumps (GHP's) and competing space conditioning equipment in the light commercial range. The economic analysis began by obtaining equipment installed costs and determining the yearly energy usage for each type of space conditioning equipment applied to a small office building and quick service restaurant in 17 cities. The installed costs of competing technologies were obtained via a survey in various cities throughout the United States. The yearly energy costs for this equipment and GHP's were calculated by using the DOE-2.1C Hourly Energy Analysis Computer Program. The DOE-2 program was modified specifically to simulate the complexity of gas heat pumps by incorporating special FORTRAN algorithms. Performance curves were developed and included in the GHP computer model based on empirical data. An economic analysis was conducted comparing GHP's and competing equipment using both payback and net present value methods which included an examination of the effect of the change in future utility costs. The results of the analysis are not included in the report because they are based on proprietary performance information.
