Not only temperature but also other factors are important influencing factors for human thermal comfort. The index of Chinese climatic regionalization for building thermal only includes the air temperature, not any other factors. And the regionalization is too big to manage hardly. The project fractionize and adjust the ‘Dividing region for building thermal design’ based on both climate and administrative division factors by learning the method of climatic regionalization in ASHRAE standard. Project also analyze the impact on building energy efficiency design. After the official signature of contract in Aug of 2012, members involved in this project fixed the detailed execution and division of proposal:

 

  •  In 12th Sep of 2012, all members had an opening meeting in Hohhot to define key technique issues and principle: the first grade regionalization would be consistent, and each of the first grade regionalization would be separated into several second grade regionalization. Results of project should be fit the demands of < Thermal design code for civil building>.
  • In 18th Dec of 2012, we had the second workshop to discuss divisional indexes which will be used in region adjustment. And we settled the indexes of second grade regionalization: HDD18, CDD26 and average temperature in the coolest month & average temperature in the hottest month.
  • In 10th May of 2013, the third meeting was conducted. Team members exchanged their research findings, discussed detail of dividing region for building thermal design and polished some works to be improved.


In the whole project, Mr. Lang (Lang Siwei) as consultant provided his ideas for research method and characteristic of climatic regionalization in US. For promising useful results to codes and standards, team members had many discussions with Mr. Lin (Lin Haiyan) who is chief editor of <Thermal design code for civil building>, <Design standard or energy efficiency of residential buildings> and <Evaluation standard for green building>).
