Gayathri Vijayakumar is a Principal Mechanical Engineer at Steven Winter Associates. For over 17 years, she has specialized in evaluating residential and multifamily buildings with an emphasis on high-performance construction and renewable energy systems.
Early in her career, Gayathri provided technical assistance to sustainability projects by performing energy modeling and conducting cost-benefit analyses of energy efficient measures in both new and existing residential construction. She leveraged that experience, and truly found her niche consulting and developing programs, codes, and standards for organizations like EnergyStar, RESNET and the International Code Council. This includes work on the EPA EnergyStar Multifamily New Construction Program as well as the Indoor airPLUS program, being chair of RESNET’s standard development committee 300, and most recently being a voting member of the 2024 IECC Residential Consensus Committee. Gayathri is one of those rare people who can organize a ton of complex information in her head, see a path forward to consensus, and help guide those who are willing to follow on a successful jury moving the construction industry forward.
