Report describing a project whose goal was to determine the prevalence of residential comfort system faults with a focus on air conditioners and heat pumps, and on key faults that can occur during installation: (1) incorrect refrigerant charge level (undercharge or overcharge); (2) indoor coil...

Report (1) compares existing measurement methods, based on field testing in a wide range of buildings, (2) presents the development of two new methods to directly measure exterior and interior leakage of an attached unit, and compares to existing methods; and (3) experimentally evaluates the...

This report outlines research activities that are expected to facilitate the adoption of energy retrofits by remodeling contractors and roofing contractors using retrofit panels which applicable to many existing house designs in most climates and markets.

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.

The next generation of building enclosures is a key step toward achieving high-performance goals through decreasing energy load demand and enabling advanced space-conditioning systems. Yet the adoption of high-R enclosures and particularly high-R walls has been a slow-growing trend because...

Report documenting the Transformative Efficiency and Automation in Modular Homes (TEAMH) project, which evaluates the integration of advanced building envelope technologies and automation-assisted modular construction to improve residential energy performance and construction efficiency.
