Brookfield Homes Passive House Performance Evaluation

Abstract

The work presented in this report does not represent performance of any product relative to regulated minimum efficiency requirements.The laboratory and/or field sites used for this work are not certified rating test facilities. The conditions and methods under which products were characterized for this work differ from standard rating conditions, as described.Because the methods and conditions differ, the reported results are not comparable to rated product performance and should only be used to estimate performance under the measured conditions.v Contents List of Figures .

Comfort in High-Performance Homes in a Hot-Humid Climate

“…Ueno and Loomis (2014) found that in new-construction high-performance test houses (in International Energy Conservation Code climate zone 5) that are heated and cooled with mini-split heat pumps, at least one ductless head unit was needed per floor to provide adequate comfort. In research conducted by Herk et al (2015), new-construction two-story homes in Denver, Colorado, showed some degree of floor-to-floor stratification. These homes had highperformance enclosures but used traditional heating and cooling air-delivery systems, which suggests a need for alternative space-conditioning systems.…”
