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

Case study examining the problem of unwanted air transfer from garage to living space and the effectiveness of garage exhaust ventilation or house supply ventilation to provide a solution to that.

Information sheet about sealing combustion appliances to ensure good indoor air quality.

Expert meeting focusing on identifying gaps and barriers in combustion safety that need to be addressed by future research, and to develop data-driven technical recommendations for code updates so that a common approach for combustion safety can be adopted by all members of the building energy...

Report on a simplified test procedure for combustion safety that is easier to implement and should produce fewer false positives than the previous procedure.

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 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...

Measure Guideline describing how to assess and carry out the isolation of natural draft combustion appliances from the conditioned spaces of low-rise residential buildings.

This measure guideline provides guidance on combustion safety inspection procedures for appliances and heating equipment that use indoor air for combustion and dilution of flue gases in low-rise residential buildings.

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.

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.
