As the expansion and extension of building indoor environment standards system, the Building Environment and Energy Efficiency Standard System (BEEESS) is the inevitable result of built environment and energy conservation. And as the most important part of the project construction standard system, it has an important role of technical support for promoting Chinese building environment and energy projects.

HVAC and building physics is the two support professions for BEEESS. According to the professional features, BEEESS are seperated into ten parts: heating and air conditioning, ventilation and purification, air quality and thermal comfort, building thermal engineering, architectural acoustics, building optics, curtain wall and window, building energy efficiency, green building and new energy and renewable energy applications. 409 standards are combed and listed, and among them 147, 42, 30, 27, 28, 25, 52, 27, 10, 34 standards is about each parts aboving respectively. There are 128 engineering standards in those standards, the ratio is 31.30%.

Accoding to investigating the status of BEEESS and combing the effective standards, we found mainly following: (1) BEEESS is basically sound, and the standards in this system nearly cover its various fields. There are obvious lack of standards in a few areas or direction, such as air quality and thermal comfort, green building, and low-carbon construction. Appropriate complements are great need. (2) Although most professional standards can be divided by its content into different parts, will some standards can not be for its professional boundaries are not clear. For absolute accuracy can not be divided according to their professional home, the standards may can be classified by purpose and technical content. (3) Because of standard demarcation remains controversial, some too small professional standards division, uneven distribution of the number of different professional standards, standards duplicate, and crossover phenomenon are existting. So analysis in-depth is necessary. (4) The phenomenons of longer compiling cycleof standard, overage (elder than 5 years), and varies match with between standard content and the standard name are more obvious. So it is recommended to shorten the standard compiling cycle, and strengthen review and cleanup about the relevant standards.
