Building-integrated renewable energy policy analysis in China

With the dramatic development of renewable energy all over the world, and for purpose of adjusting energy structure, the Ministry of Construction of China plans to promote the large scale application of renewable energy in buildings. In order to ensure the validity of policy-making, this work firstly exerts a method to do cost-benefit analysis for three kinds of technologies such as building-integrated solar hot water (BISHW) system, building-integrated photovoltaic (BIPV) technology and ground water heat pump (GWHP). Through selecting a representative city of every climate region, the analysis comes into different results for different climate regions in China and respectively different suggestion for policy-making. On the analysis basis, the Ministry of Construction (MOC) and the Ministry of Finance of China (MOF) united to start-up Building-integrated Renewable Energy Demonstration Projects (BIREDP) in 2006. In the demonstration projects, renewable energy takes place of traditional energy to supply the domestic hot water, electricity, air-conditioning and heating. Through carrying out the demonstration projects, renewable energy related market has been expanded. More and more relative companies and local governments take the opportunity to promote the large scale application of renewable energy in buildings.
