Episode Info

Episode Info: Curious about how building performance standards are decided upon? The IECC, or “model code”, establishes the minimum requirements for building energy efficiency by specifying the performance levels for the building envelope, mechanical systems, lighting systems, and service water heating systems in homes and commercial businesses. This model code is updated every three years, and within those three years there is a LOT of behind-the-scenes work going on to determine the changes for the next version. In this episode, we learn all about the long and lengthy code development process from SWA’s own Gayathri Vijayakumar. Episode Guest: Gayathri Vijayakumar, Director, Residential Energy Services, Steven Winter Associates, Inc.  For 15 years, Gayathri Vijayakumar has specialized in evaluating residential and multifamily buildings with an emphasis on high-performance construction and renewable energy systems. Gayathri is a Director for Residential Energy Services at SWA, supporting team members on their energy efficiency, research, and product development projects. She also provides consulting to federal, state, and local agencies, codes, and programs to develop emerging standards and procedures that involve energy efficiency requirements. Gayathri currently is a member of the ASHRAE 62.2 Multifamily Working Group, Chair of RESNET’s Standards Development Committee, SDC300, and a voting member of ASHRAE’s Residential Buildings Committee.   Episode Information & Resources *Scroll down for episode transcript!
