Research on the knowledge demands of multiple subjects for energy efficiency improvement in Chinese public buildings

Abstract

At present, China's public building energy efficiency improvement projects lack vitality in the market due to the weak awareness of energy efficiency among the participating subjects. Therefore, improving the knowledge and awareness of all participating parties has become the key to effectively promoting energy efficiency improvement in Chinese public buildings. This paper researches the knowledge demand of key subjects for energy efficiency improvement in public buildings(EEIPB), establishes a knowledge demand indicator system for EEIPB, and proposes targeted knowledge improvement methods. Firstly, the knowledge demand of key subjects for EEIPB is identified by using grounded theory, and the knowledge demand indicator system for EEIPB is established. Secondly, the knowledge demand categories are determined with the help of the improved Kano’s model, and the priority of the knowledge demand elements of each subject is derived through Better-Worse index analysis. Finally, suggestions on the learning paths for Better-Worse index analysis are put forward. It is found that the demand for various subjects for knowledge on EEIPB is mainly focused on five aspects: incentive policies, regulations, standard specifications, market, and technology. In terms of demand, the types of knowledge demand elements for EEIPB of each subject are mainly One-dimensional Attributes and Mixed Attributes among which incentive policies and market are the focus of attention of each subject. In addition, there are both commonalities and differences in the knowledge demands of each subject. This research will help government authorities formulate effective promotion measures for the demand for energy-efficiency improvement knowledge in public buildings and raise the level of energy-efficiency knowledge awareness of all subjects in the public building industry.
