Modeling for Building Energy Savings

Modeling for Building Energy Savings


  • Mahabir Bhandari, ORNL Building Technologies Research and Integration Center, Oak Ridge, TN
August 24, 2015 - 10:30am to 11:30am


Buildings use 41% of the energy used in the United States, and consumption is projected to grow by 25% in the next two decades. Use of energy simulation tools in the design of energy-related building systems is essential for identifying methods that improve building efficiency. A recent study showed that buildings designed with simulation consume 44% less energy. Buildings researcher Mahabir Bhandari will discuss how EnergyPius, DOE's open-source flagship, whole-building energy simulation engine improves energy analysis through calibration of building simulation models using detailed measured data. Bhandari will also present how simulations can be applied to challenging needs based on case studies on site-wide energy savings and assessment analysis.
