Research report describing the development of standardized test methods for PM2.5 and CO2 sensors enabling reliable, low-cost indoor air quality monitoring and improvement.

Test method that measures the capture efficiency of wall-mounted domestic range hoods under controlled conditions in a test chambers which available for preview and purchase at the link and was published in the year 2018.

The manual covers residential zoning issues - multiple, single-zone, and central multi-zone systems - and includes advice on working with homeowners to adapt the heating or cooling system design to meet modern home design features.

Report detailing the effects of replacing PSC motors with more efficient, variable-speed motors.

Report describing the use of fresh air ventilation systems to eliminate the formation of icicles and ice dams along the eaves of roofs.

Standard describing methods for testing the airtightness of buildings and HVAC equipment.

Report describing the results of a 21-home field study investigating the effectiveness and failure rates of whole-house mechanical ventilation systems installed in Florida homes over the last 15 years.

Report describing the results of a field study of five different ventilation system types in 29 homes in the Pacific Northwest.

Article describing the impact of increasingly stringent ventilation standards on multifamily buildings, highlighting the inefficiencies and challenges of exhaust-only ventilation in tightly sealed enclosures, the complications of achieving balanced ventilation, and the unintended consequences of...

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

Document presenting analysis results, focusing on relative humidity (RH) excursions, which are defined as unique events of indoor RH above a threshold.

This study used an advanced airflow, energy and humidity modeling tool to evaluate the potential for residential mechanical pre-scooling strategies to reduce peak electriciy demand.

This Standard provides a consistent, uniform methodology for evaluating the airtightness of building envelopes and heating and cooling air ducts and the air flows of mechanical ventilation systems.

Study using simulations to understand the impact that shading and natural ventilation would have had on the survivability of non-air-conditioned buildings during the 2021 heat wave in the Pacific Northwest.

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.

This research study used pollutant measurements, home inspections, diagnostic testing and occupant surveys to assess IAQ in 24 new or deeply retrofitted homes designed to be high performance green buildings in California.
