What’s the most effective way to conduct an energy rating on a multifamily building?  


Join us as Gayathri Vijayakumar (Steven Winter Associates, Inc.) discusses the efforts of a dedicated group of individuals that has moved multifamily building energy ratings from guidelines to become a part of the existing HERS standards 301 and 380.


We also learn of Gayathri’s passion for her work, her love of solar, and what has driven her career to this point at Steven Winter Associates.


You will gain a clearer picture of how standards are made and most importantly, updated regularly through research and public comment.


Learn about what constitutes a multifamily building and how some of the assessments and tests are performed.


You can learn more about the standards at RESNET’s website:


And keep up to date with pending standards amendments here:


Gayathri offers her email address for you to get in touch,, and you may also run into her at the RESNET conferences.


Some of the people that devote many hours helping to develop and improve these standards are:
