Building Simulation Conference Papers



2014 ASHRAE/IBPSA-USA Building Simulation Conference
September 10-12, 2014
Atlanta, GA

ASHRAE and IBPSA-USA are convening this conference to improve the industry's ability to accurately model building performance. The conference merges the IBPSA-USA SimBuild and ASHRAE Energy Modeling Conferences. The focus is on making better decisions through the application of simulation and modeling over the entire building life cycle from the earliest concept through operation and maintenance.
