Research of the market appeal of solar houses in Yangtze River Delta Area

As one of the world's biggest countries with respect to energy consumption and greenhouse gas emission, China is faced with some crucial environmental problems. The construction of new-energy infrastructure became significant under such a circumstance, since 50% of energy is consumed in buildings in China. Yangtze River Delta Area is seriously suffered with energy shortage because of its climate. On the other hand, as the center of capital and technology in China, this area has already established scaled solar energy industry.

Basing on the circumstances stated above, we focused our project on the promotion of solar house. Our project is composed of five parts: theoretical proof, quantum calculation, investigation, conclusions and suggestion. We analyzed the data collected from our model solar house on campus. Then we surveyed some representatives from five relevant interest groups and some scholars by means of interview and questionnaire to explore ways of promoting solar house in the Yangtze River Delta Area. Finally, specific and effective suggestions were offered to the government based on the outcomes.

Our team collected 2000 questionnaires from local residents and students in both urban and rural areas in Zhejiang province, Jiangsu province and Shanghai. The data was used to analyze purchase inclination, subsidy requirements and other relevant aspects. Besides, we interviewed some representatives from PV companies, real estate companies and construction companies and scholars. The interview was carried out via video, phone or in person. Videos and recordings are used for analysis afterwards. Moreover, we made careful and comprehensive calculations based on the data collected from our modeled solar house in Shanghai Jiao Tong University and data promulgated by National Bureau of Statistics of China and National Development and Reform Commission. A conservative evaluation was made on the consumption of energy according to the data concerned above and results of our questionnaires.

Our research combined together theoretical outcomes and marketing data, referring to comprehensive viewpoints from relevant representatives ranging from scholars to practitioners, to present practical suggestions for government.

The research covers architecture, electrical engineering, mechanical engineering, environmental science and many other disciplines. Two thousand questionnaires and comprehensive interviews provide us with latest and reliable data, contributing to a practicable outcome.
