As the demands on buildings and community energy systems increase, all the while requiring better energy performance, building energy simulation programs need to keep pace.

These programs do important work, including integrating renewable energy and waste heat, providing grid services and generally making people more comfortable in the spaces they occupy.

Michael Wetter, Staff Scientist at Berkeley Lab, recently spoke at an International Building Performance Simulation Association (IBPSA) hosted seminar. He presented Department of Energy sponsored technologies and open-source standards that are well positioned to address the more integrated and complex building systems we have today. These technologies include Spawn of EnergyPlus, OpenBuildingControl, Modelica and Functional Mock-up Interface (FMI) Technologies.
