On the 12th-16th of June 2017, SusBuild project organized training workshops on the topics of “ESCO and building energy retrofit” and “green construction” in Chongqing and Kunming. The trainings were hosted by SusBuild local partners, with the support of the Ministry of Housing and Urban & Rural Development in China and housing authorities from both regions. 
70 and 50 participants from ESCO companies and local building design institutes participated in the “ESCO and building energy retrofit” training in Chongqing and Kunming, respectively. 

During both trainings, Professor Junwei Yan, vice chairman of China Association of Building Energy Efficiency (CABEE), presented the principles, different models, the procedure, and M&V of Energy Performance Contract (EPC) as well as EPC policies in China and illustrated the EPC model with several good practice projects, such as a university campus, governmental buildings, and large shopping malls. Besides, he also introduced the systematic approach of public and commercial building energy retrofit with a focus on HVAC. His lecture was followed by local experts’ presentations.

In Chongqing, Professor Ding Yong, vice chairman of Chongqing Association of Building Energy Efficiency (CQABEE), presented the systematic approach for building energy retrofit and project examples in Chongqing. He also highlighted the importance of green retrofitting to enhance indoor comfort. In Kunming, Prof. Ni Shijin, the deputy director of Kunming Medical University Hospital, shared his experience in energy retrofitting. The energy retrofitting project realized a 35% performance in energy intensity reduction, based on detailed energy use analysis and a combination of technologies, such as solar hot water, replacing oil boiler with gas boiler and soft measures, such as the establishment of a energy saving leader group, and various “carrot and stick” measures. Mr. Liu Zhenrong, senior engineer from Yunnan building technology development center (YBTDC), presented building energy management practices for public and commercial buildings in Yunnan. He also introduced the progress of establishing an energy consumption monitoring platform in Yunnan. Next, Mr. Liu Shao Yong from YBTDC introduced an innovative web tool for energy consumption data monitoring, which will benefit building owners, energy efficiency professionals, and governmental agencies.  

The “green construction” training brought together XX and XX participants from Chongqing and Kunming, respectively. The training embraced both European and Chinese experiences of green construction. In both Chongqing and Kunming, Mr. Sun Pengcheng, senior expert from China Building Technology Center, introduced the concept, development, and policies of green construction in China and its relation to other key policies in the building sector. He then presented some advanced technologies and their applications in good practice projects. Mr. Christopher Moore, senior researcher from Wuppertal Institute, shared policies and measures of green construction in Europe, and illustrated green constructions with detailed examples and good practices in Europe. Both experts strengthened the importance of Building Information Modeling (BIM) and presented examples of BIM application and its advantages. In Kunming, Mr. Qing Shan from Kunming Science and Technology University, introduced a good practice project of Wanda in details. 
Both ESCO development and green construction are essential for the sustainable building sector. These trainings have raised high interest from participating SMEs as well as governmental agencies and think tanks. All presentations (in Chinese) can be downloaded here. Two handbooks based on training content will be available later this year.
