ABSTRACT
In 2001, the . Department of Energy (DOE) initiated a rulemaking process to consider
whether to amend the existing energy efficiency standards for furnaces and boilers. A key factor
in DOE’s consideration of new standards is the economic impacts on consumers of possible
revisions to energy-efficiency standards. Determining cost-effectiveness requires an appropriate
comparison of the additional first cost of energy efficiency design options with the savings in
operating costs. DOE’s preferred approach paring the total life-cycle cost (LCC) of
owning and operating a more efficient appliance with the LCC for a baseline design. This study
describes the method used to conduct the LCC analysis and presents the estimated change in
LCC associated with more energy-efficient equipment. The results indicate that efficiency
improvement relative to the baseline design can reduce the LCC in each of the product classes
considered.
