The Building America Program continues its webinar series into 2018! Each free webinar will offer information about the latest advances in residential building technologies and practices, presented by Building America research team and national laboratory experts.
Technical Resources at Your Fingertips: DOE's Building America Solution Center and Standard Work Specifications Guidance for Existing Homes
Time: June 26, 2018, at 3-4:30 p.m. ET
The Building America Solution Center (BASC) is your best friend if you have anything to do with high-performance homes. It provides extensive, up-to-date content needed to integrate building science best practices in specifications, field applications, education, and code official meetings. This session will present the new Existing Homes Tool, which provides installation guidance for making existing homes more energy efficient, comfortable, and less expensive to operate. The tool is designed around common upgrades, and is organized by steps, which are numbered to indicate priorities from a health and safety standpoint.
The BASC Existing Homes tool links directly to the DOE Standard Work Specifications which define the minimum requirements to ensure that the work performed during home energy upgrades is effective, durable, and safe. Both tools can assist all existing homes stakeholders with finding best practices in existing homes. Join us for an in-depth tour of both tools and learn how they link to each other.
Building America: Field Studies of Indoor Air Quality in New U.S. Homes
Time: July 11, 2018, at 3-4:30 p.m. ET
Since 2008, California has required whole dwelling mechanical ventilation compliant with ASHRAE Standard 62.2. A field study was undertaken to measure ventilation system airflows, air pollutant concentrations, and exhaust fan use in these homes to determine if the ventilation systems are providing acceptable indoor air quality, as intended. Concentrations of fine particulate matter (PM2.5), NO2, NOX, and formaldehyde were measured inside and outside of 70 homes over one-week periods. The homes were characterized for air leakage and the air flows of all ventilation systems were measured and monitored during the study. The results show, when operating, the installed ventilation systems provided adequate flow to meet the standard and that pollutant levels were below acceptable limits, except for formaldehyde, which exceeded California's very stringent reference exposure level, but was well below the WHO standard. Significantly, most of the systems were not operating when researchers arrived at the study homes. This raises serious issues regarding operational requirements and configuring and labeling of ventilation system controls.
Building America is supporting a similar, but greatly expanded, field study to collect data on indoor air quality (IAQ), ventilation and IAQ controls in new homes in four U.S. climate zones. Field teams are measuring ventilation equipment airflows and installing sensors to monitor exhaust fan use and indoor air quality parameters over a week-long period. Roughly half of the study homes will have ventilation systems intended to comply with ASHRAE Standard 62.2. We will present a detailed list of air pollutant and other data collection targets for this study. The data from these studies will inform builders and manufacturers, as well as industry ventilation standards and code provisions, to better protect indoor air quality and health as building infiltration is reduced to save energy.
