Report on experiments comparing the cooling and heating seasonal and peak demand performance of different variable-capacity air conditioning and heat pump units.

Report outlining the issues with using existing ducts with a new low-load HVAC system, which reduces throw at supply registers causing decreased mixing of supply and room air, leading to potential thermal comfort complaints.

Report about an experimental evaluation conducted on a night sky cooling system designed to substantially reduce space cooling needs in homes in North American climates.

DOE-sponsored report describing a study investigating condensation buildup on windows when using insulating shades.

Factsheet profiling a simple modification that can be made to window air-conditioners to improve their energy efficiency.

The study described in this white paper is based on building energy modeling with an important focus on the indoor humidity impacts of ventilation.

This report investigates whether mini-split heat pumps can live up to their potential for one market segment: multifamily retrofits.

Report describing the experimentally evaluated potential of a novel residential night cooling concept.

Webpage describing a DOE Cold Climate Heat Pump Challenge. The challenge engages industry partners and focuses around the Cold Climate Heat Pumps, a more environmental and efficient heating alternative to traditional heating.

Report evaluating mechanical AC precooling strategies in homes as a method for improving the load factor by shifting cooling operation from on-peak to off-peak hours.

DOE report characterizing the installed base of windows and window coverings, and how users operate window coverings in order to enable precise quantification of energy savings.

This research paper outlines residential HVAC advanced controls and sensors. It includes a technology review, applications, maintenance and commissioning, occupant behavior and a summary of the state-of-the-art technologies for advanced controls for residential HVAC.
