DOE published MEEA Case Study on Iowa Furnaces

On Monday December 9th, the U.S. Department of Energy's Building America Program published the case study, Improving the Field Performance of Natural Gas Furnaces. MEEA worked in conjunction with its Partnership for Advanced Residential Retrofit (PARR) team members to collect and analyze working furnaces that were removed from Iowa homes.

The purpose of this research was to investigate the impact of age degradation and typical installation practices on the steady-state furnace efficiency. This research found that ‘typical’ field installation practices result in less than optimal steady state efficiency and that normal furnace equipment age degradation does not impact steady state efficiency. This research is important to MEEA’s HVAC SAVE program because it supports the principal that improved installation practices, similar to what is taught in the HVAC SAVE program, can improve a furnace’s in field operating efficiency.

The Building America Publications Library offers an extensive collection of technical reports, measure and strategy guidelines, case studies, and other resources to help you boost energy efficiency in new and existing homes. Also, the Building America Solution Center links you to expert building science and energy efficiency information based on Building America research results.
