Green Proving Ground webinar on a test-bed evaluation of automated building envelope sealing. Air leakage is a significant driver of energy use within buildings that can negatively impact thermal comfort, indoor air quality, and mechanical ventilation systems operation. Researchers from the Oak Ridge National Laboratory evaluated automated air sealing during a renovation at an office building at the Denver Federal Center. They found that the technology increased airtightness by more than 50% from an already airtight envelope. During the webinar, researchers and facility managers will discuss findings from the project evaluation, share operational guidance, and answer questions.
