The research work route is mainly focusing on the “Energy consumption monitoring - Energy efficiency diagnosis - Intelligent controlling - Equipment development - Big data operation” in the process of public buildings energy conservation. By using the basic common theoretical techniques of Iot of building energy consumption, accurate evaluation of building energy efficiency, intelligent control & adjustment, and intelligent equipment development, the following academic achievements have been achieved in the past five years.

Firstly, as one of the main executors, a technique system named Internet of Building Energy System (iBES) was proposed and built, which can sufficiently solve the theoretical problems, such as data optimal collection, precision guarantee, network architecture, data transmission and Data processing & sharing, remained in the process of building energy consumption optimization. There are lots of engineering applications of iBES in China nowadays (including 338 demonstrating buildings, covered area of 6.18 million m2).

Secondly, as one of the main executors, the Energy Performance Diagnosis and Optimization Control (EPdoc) for the whole life process of existing buildings was proposed, which provided referable energy efficiency indexes for the whole life process of existing buildings by bonding with iBES demonstrating buildings.

Finally, combined with big data of energy consumption and energy efficiency evaluation & diagnosis methods, aiming at the problems of high energy consumption of HVAC system operation, poor indoor thermal comfort, and the coexistent nonlinear characteristics among multi-variable, multi-input-multi-output (MIMO) and time-varying coupling, the intelligent control theories and methodologies of building environment were established. Which includes the techniques of the most unfavorable thermal loop identification, the thermal stability of pipe network evaluation, the fan-coil fuzzy duty ratio control, the T-S model based predictive control of chiller, the fuzzy control of parallel pumps frequency conversion, etc.

In recent five years, several projects and funds had been hosted, including 2 National Natural Science Foundation of China (NSFC), 2 sub-projects of National Key Research and Development Project, 1 APEC International Cooperation Project, 1 Science and Technology Project of Ministry of Housing and Urban-rural Development, 1 Dalian Municipal Science and Technology Plan Project, 1 Fundamental Research Funds for the Central Universities, 3 Technical Development and Service Projects, the total research expenditure was 14.612 million yuan. More than 80 academic papers were published, 1 APEC monograph (31 thousand words) was published, 3 patents for invention and 3 software copyrights were obtained. Supervising 14 master students and 1 Ph.D. student, assist-supervising 5 Ph.D. students. In 2016, he was appointed as the expert of energy working group and building energy efficiency & saving expert group by APEC. The same year, he was selected as the science & technology star of Dalian municipality. In 2017, he was voted as one of the "One Hundred Outstanding Youth of HVAV&R" by chinese magazine called “Heating Ventilating Air Conditioning”.
