The Urban scale simulation research sub-committee of IBPSA-USA webinar series will introduce latest research on the urban scale modeling and simulation. We will kick off our first webinar with Dr. Tianzhen Hong from LBNL, USA: Urban Modeling For Large-Scale Assessment of Building Energy Efficiency Improvements.


Buildings in U.S. cities consume up to 70% of the total primary energy. To achieve cities’ energy and climate goals, it is thus a key strategy to reducing energy use and GHG emissions in urban buildings through energy conservation and efficiency improvements. Urban building energy modeling (UBEM) is a powerful tool for cities and their energy planning consultants to assess the building stock and guide building retrofits at city-scale. The seminar presents LBNL's research on data, methods, tools and case studies of UBEM. Opportunities and challenges of UBEM will be discussed.

Speaker Bio:

Dr. Tianzhen Hong is a Staff Scientist and Deputy Head of Building Technology Department. At LBNL, he leads the EnergyPlus development and co-leads the urban systems initiative at EnergyTechnologies Area. He also leads the urban building energy modeling as part of an exascale computing project collaborating with ANL, ORNL, NREL and PNNL. 

About the Urban Scale Simulation Subcommittee:

The Urban Scale Simulation Subcommittee is part of the Research Committee of IBPSA-USA. The IBPSA-USA Research Committee promotes research activities in building performance simulation by advocating research outcomes, facilitating research exchange, and generating new research ideas and so on. The committee meets monthly, and three subcommittees meet quarterly. Additionally, the committee hosts and sponsors events to develop research objectives and make building simulation practitioners aware of new advances in the field.
