On June 5, Berkeley Lab and the China Association of Building Energy Efficiency (CABEE) conducted a joint workshop on building energy data and provincial energy calculation. The workshop was conducted to support China in developing a Better Buildings China Pilot Program – a voluntary energy efficiency market transformation pilot program modeled after the U.S. Better Building Program which aims to reduce energy intensity in the Chinese buildings sector by 20% over ten years.
Over 40 people participated in the workshop, including researchers from CABEE and key building research institutes such as China Academy of Building Research (CABR), Shanghai Institute of Building Research, Shenzhen Institute of Building Research, Henan Institute of Building Research, Liaoning Institute of Building Research, Sichuan Institute of Building Research, Shanxi Institute of Building Research, and Beijing University of Civil Engineering and Architecture (BUCEA).
The workshop focused on application of tools and methodologies for collecting regional and provincial building energy data and calculating municipal and provincial building energy consumption from 2000 to 2015. The data will serve as a basis for the Better Buildings China Pilot Program, supporting the development and application of building energy models; building energy benchmarking and auditing tools; best-practice energy efficiency measures; and case studies to improve energy performance in Chinese buildings.
During the morning session, participants introduced their research progress on building energy consumption calculation in their regions. Berkeley Lab and CABEE provided comments on their research findings and made suggestions on further research. During the afternoon session, Berkeley Lab provided training on the Long-Range Energy Alternatives Planning System (LEAP) software and the LEAP-based GREAT Modeling Tool that can support regional and provincial building energy data collection and analysis. Berkeley Lab staff introduced and worked with participants to understand how to develop building energy modeling structures, key input data for these modeling tools, and methodologies for regional long-term building energy demand forecast. The trainees found LEAP and GREAT model helpful for future use in identifying pathways, energy conservation measures, and policies to reduce energy use in buildings in the long run.
Building on this workshop, CABEE, research institutes, and Berkeley Lab will work together to further develop municipal and provincial building energy databases; energy consumption calculation models; benchmarking and auditing tools; and energy efficiency best-practices and case studies to support the Better Buildings China Pilot Program.
