Book Description
Various levels of investment in energy-efficient designs are analyzed for new single-family detached dwellings. The purpose is to develop relationships between initial cost and annual energy savings in space heating and cooling for use in the ORNL residential energy use simulation model. The analysis is performed for a 1200 ft2 ranch-style home in nine U.S. locations using both natural gas or electricity. The annual loads calculation and cost survey are based on a report by Petersen at the National Bureau of Standards, which used the NBSLD computer code. The economic analyses, which minimize lifecycle costs, were conducted using an updated version of a computer program written at ORNL. Results define relationships between annual energy savings in space heating and cooling versus additional initial cost, which demonstrate the law of diminishing marginal returns. Curve characteristics are generally a function of climate, although the order of implementation for the various energy-conserving options (heating only) is basically constant across all regions. Potential reductions in annual energy use range from 30 to 60% when compared to the present 1974 Housing and Urban Development Minimum Property Standards (HUD--MPS). Optimum levels of investment in energy-conserving design for heating only were computed for each location. When compared to the 1974 HUD--MPS, major differences were noted for all but the natural gas-heated homes in areas less than 5200 heating degree days. Paybacks for additional investment above the current standard range from 15 to 20 years for natural gas users and four to six years for electrically-heated homes.
