A workshop on Plus Energy Building was held in Beijing on March 21, 2019. It was jointly organized by the GIZ and the Department of Standard and Norms of the MoHURD.
Plus Energy Building/District is one of the future key topics of SGUP. Plus Energy Building refers to buildings that produce more energy than they consume. The surplus can be used to provide energy for other neighboring buildings, electronic vehicles, or surplus electricity for the public grid. In recent years, the construction industry has produced a very high share of carbon dioxide emissions, waste production, and resource consumption. As people pay stronger attention to sustainable development, the demand for energy conservation and emission reduction is increasing.
Currently, there is no specific comprehensive energy efficiency law for buildings in China. The regulations related to energy efficiency are distributed in different codes. Compared with China, Germany has strong energy efficiency regulations for its buildings. For China, it is recommended to strengthen the legislative work to improve the legal regulations of energy efficiency in its building sector.
China’s incentive policy on Building Energy Efficiency is similar to that of Germany, mainly in the form of project subsidies or rewards. It is recommended to develop long-term incentive policies, such as green finance and sustainable certification.
In terms of technology, some active technologies such as solar energy, photovoltaic, ventilation heat recovery, ice thermal storage and heat pump, which are often used in plus energy buildings in Germany, can be used in China. Some passive technologies such as wind tower and buffer water tank are also applicable in China.
It is recommended to clarify the definition of Plus Energy Building and to introduce key indicators such as energy consumption, evaluation criteria for plus energy buildings. In addition, there is the need to strengthen the application and promotion of related technologies in different climate zones.
The Deputy Director General of MoHURD Mr. Guo Liqiao, the Division Chief Mrs. Zhao Wenhua, the Project Director of SGUP Mr. Peter Sailer and the Chief Engineer from Beijing Uni Construction Group (BUCC) Mr. Yang Jiankang attended the workshop.
