• Drain Water Heat Recovery

  The drain water heat recovery (DWHR) measure is completely new in the California Building Energy Efficiency Standards, and saves water heating energy expended during showering. This measure applies to new construction of low-rise residential buildings. DWHR is likely cost-effective in some high-rise ...

• Compact Hot Water Distribution Design

  The Compact Hot Water Distribution proposal is intended to provide builders a compliance option credit for designing residential buildings with hot water use fixtures located close to the water heater, saving both energy and water. A compliance option represents a voluntary measure available to builders ...

  Under the 2013 and 2016 code, a compliance credit is awarded for installations that perform Quality Insulation Installation (QII). The Standard Design assumes that builders are not performing QII and wall insulation values are modeled at 70 percent of the R-value of the installed insulation, with attic ...

• High Performance Windows and Doors

  This measure improves the performance of fenestration products—windows and doors—in the low-rise residential buildings by lowering the required U-factors for both products, and for windows by adjusting the solar heat gain coefficients (SHGC) by Climate Zone to further reduce energy use ...

• High Performance Attics

  The proposed residential high performance attic (HPA) measure increases the prescriptive performance of the residential envelope in certain climates, primarily reducing the cooling season heat transfer through the roof deck, contributing to lower heating, ventilation, and air conditioning (HVAC) loads ...

• High Performance Walls

  The proposed residential high performance walls measure increases the prescriptive performance of the residential envelope in certain climates, reducing the amount of heat transfer through walls and subsequently reducing heating, ventilation, and air conditioning (HVAC) loads ...
