Bio

Dr. Mahabir Bhandari is an R&D Staff member in ORNL’s Building Envelope & Urban Systems Research Group. He has more than 20 years of experience in the field of building energy performance. He is a LEED™ Accredited Professional Building Design + Construction (BD+C) and National Fenestration Rating Council (NFRC) certified simulator and has actively participated in several LEED™ and sustainability projects and contributed significantly in building energy software product developments. He received his Ph.D. degree at Center for Energy Studies of Indian Institute of Technology, Delhi, India.  Prior to joining ORNL, Mahabir worked as a post-doctoral fellow at the Mechanical and Industrial Engineering department of the University of Massachusetts, Amherst and Technical Director at DesignBuilder software, USA. In recent years, his focus has been on fenestration research, whole building energy simulation, manual and auto calibration, industrial energy data analysis for energy savings impact, Combined Heat and Power (CHP) deployment analysis, building energy monitoring and performance analysis and the evaluation and integration of energy-efficient technologies in buildings. He currently serves on the  NFRC and Attachment Energy Rating Council (AERC) Board of Directors.
