Document providing guideance and considerations for duct design in an energy efficient house.

Report identifying two barriers that limit the ability of builders to explore opportunities for higher levels of energy efficiency in housing: the use of duct system materials that inherently achieve airtightness and are right-sized for low-load houses, and, the ability to air seal fire separation...

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 providing the results of an analysis of humidity control and variable refrigerant flow (VRF) system efficiency in three new multifamily buildings in New York, NY.

Report providing step-by-step instructions for heating contractors and hydronic designers for selecting the proper control settings to maximize system performance and improve response time when using a thermostat setback.

Report describing solutions for supplemental dehumidification in warm-humid climates.

Report providing extensive guidance on controlling moisture in building envelopes through proper selection and installation on air, water, thermal, and vapor barriers.

Information sheet describing how to select a properly sized water heater based on household usage patterns, peak demand, and heater type—whether tankless, solar, or storage-based—to ensure efficiency and adequate hot water supply.

Fact sheet describing the results of an analysis of humidity control and variable refrigerant flow (VRF) system efficiency in three new multifamily buildings in New York, NY.

Preliminary results of two monitored lab homes constructed to represent the thermal characteristics of typical existing Florida homes are presented.

This report describes how twenty homes were tested and monitored in the Zone 2 climate of Houston, Texas, U.S.A., to evaluate the humidity control performance and operating cost of six different integrated dehumidification and ventilation systems that could be applied by production homebuilders.
