A Clean and Efficient Building Sector in China
China is the world's biggest energy consumer and CO2 emitter. The building sector in China takes about 20% of the country's total energy consumption and it is expected to grow fast over time. Through the U.S. China Clean Energy Research Center (CERC), many research activities have been carried out to collaborate with China on building energy efficiency and distributed energy systems. This presentation covers some past collaborations with China on building codes, standards performance evaluation, and building sector long-term modeling. It also introduces ongoing research on distributed energy system modeling and direct current (DC) power systems in buildings. The modeling and simulation research demonstrate the opportunities to reduce primary energy consumption in China's building sector by 50% in 2050.

Wei Feng is a Research Scientist at Lawrence Berkeley National Laboratory (LBNL). His research focuses on building energy efficiency, distributed energy system in buildings and communities, building codes and standards. He also actively work on Smart Grid and microgrid research, Direct Current (DC) power use in low voltage power distribution system.
Dr. Feng has been working in energy area since 2003. Prior to joining LBNL, he worked in control industry in China focusing on building system control for energy efficiency, performance measurement, diagnosis and commissioning. In the U.S., his previous research interests include developing combined heat, moisture and pollutant transport models for whole building performance analysis, built environment modeling and simulation, indoor environmental quality measurement, etc.
Dr. Feng currently leads the DC power research in the U.S.-China Clean energy Research Center-Building Energy Efficiency (CERC-BEE). He is also the lead of Net Zero Energy Building work in CERC-BEE. His active research also include modeling building sector energy use in cities; City scale energy simulation focusing on stochastic energy use prediction; district energy system modeling with cascade waste heat utilization; GIS based microgrid system modeling; DC power demo building performance simulation and measurement.
