Feasibility of positive energy districts in China: research report by the China Academy of Building Research

China is aiming to achieve climate neutrality by 2060. President Xi Jinping announced this ambitious target at the United Nations General Assembly in September 2020. One of the areas that the country is focusing on as a means of achieving this target is the sustainable transformation of the building sector, in particular promoting energy efficiency in buildings and integrating renewable energy into the construction industry.

The China Academy of Building Research (CABR), a re search institute subordinate to China’s Ministry of Construction, is investigating the feasibility of positive energy districts in cooperation with the Deutsche Energie-Agentur (German Energy Agency – dena). CABR’s research project on positive energy districts began in December 2019 and is expected to be completed in March 2021.

A positive energy building or district (other terms include plus energy or energy-plus) is a building or urban district that generates more energy than it requires for its own needs. The basic premise in such cases is that the energy is obtained from renewable sources.
