Residential energy codes have rapidly advanced, and many builders offer “Net Zero Energy” or "Zero Energy Ready" homes. But as homes get more efficient, risks of design and installation defects increase. Increased insulation can elevate moisture risk inside wall assemblies. Increased air tightness can lead to IAQ problems without proper ventilation. Lower envelope loads reduces HVAC system air flow and can lead to poor comfort control. Energy efficient homes must also be high performance homes. This presentation will describe innovative solutions for high performance homes and retrofits under U.S. DOE’s Building America program that minimize risks and maximize comfort.
