This report evaluates the performance of variable-capacity comfort systems, with a focus on inverter-driven, variable-capacity systems, as well as proposed system enhancements.

Report outlining how Smart ventilation controls (SVC) balance energy consumption, comfort, and IAQ by optimizing mechanical ventilation operation to reduce the heating and/or cooling loads, improve management of indoor moisture, and maintain IAQ equivalence according to ASHRAE 62.2.

Guide by the Northeast Energy Efficiency Partnerships on how to size heat pumps in a cold climate.

Website providing the technical specifications and related documents for home builders, subcontractors, architects, and other housing professionals interested in certifying a home to the EPA's Indoor airPLUS program requirements.

Blog article describing considerations for how to use trees for shading to reduce cooling energy demand.

Report providing guidance on indoor air quality in single-family and multifamily housing for designers, builders, property managers, homeowners, buyers, and renters.

DOE-sponsored report describing the experimental design and results of testing the energy performance of Hunter Douglas double-cell cellular shades under various control schemes in the Pacific Northwest National Laboratory’s Lab Homes.

Conference paper summarizing the relative performance of currently available Heat Pump Water Heaters (HPWH) models, the energy implications of different installation locations (garage, basement, or conditioned space) and ducting configurations (exhaust ducting, full ducting, or no ducting), as well...

Article describing a field study that test ventilation performance in nine homes and found current ventilation was inadequate to remove PM2.5 and CO2 levels; however, a directly exhausting range hood can reduce peak PM2.5 concentrations by 75% or more.
