Evaluation of the Performance of Houses With and Without Supplemental Dehumidification in a Hot-Humid Climate

Understanding indoor humidity conditions in low energy homes in hot-humid climates is critical to promoting long term occupant comfort, indoor air quality and building durability. The results of this study were expected to inform the residential building community on whether supplemental dehumidification is a needed and effective investment to promote these long term standards. Data logging equipment was installed at eight test homes in July, 2012 and later at two more test homes in January, 2013. Interior conditions and various end-use loads were monitored until November 7th, 2013. The mechanical systems at each of the 10 homes were commissioned by BSC to ensure consistent operation between each of the homes and to fully comply with the intended mechanical design.
