The Influence of Thermal Inertia Index on the Residential External Walls in Hot-Summer and Cold-Winter Areas Min Xiao 1,2,a, Guoqiang Zhang 1,b 1 College of Architecture, Hunan university, Changsha, Hunan 410082, PR China 2 School of Civil Engineering and Architecture, Changsha University of Science and Technology, Changsha, Hunan 410076 PR China axiaominhn@163.com, bgqzhang@188.com Key words：thermal inertia index；residential external walls；research on the influence Abstract: The evaluation method of residential building envelope thermal performance in hot-summer and cold-winter area is different from the method of the cold northern regions, that is, the merit of the thermal performance of walls and roofs should not be determined only by the heat transfer coefficient K or thermal resistance R, the impact of the thermal inertia index on the thermal performance of building envelope should also be considered.
The evaluation of thermal engineering quality of envelope structure in residential buildings followed the evaluation system in cold areas in North China, which use heat conducting index K or thermo resistance R to evaluate the thermal engineering quality of wall and roof.
It lacks of the research on thermal engineering quality of the envelope structure in such areas, which led to the construction practitioners’ confusion of two concepts “hear preservation” and “heat insulation”, and the difficulties of conducting appropriate design and research of thermal engineering based on the unique climate characteristics in areas that are hot in summer and cold in winter.
This thesis will be helpful for designers to adopt appropriate materials and structures in future work and obtain a better and scientific evaluation of the thermal engineering quality of external envelope structure of energy-saving buildings. 1.
The thermal engineering qualities of the 6 types of exterior wall are listed in table 2.

The common definition of structure vulnerability in engineering earthquake analysis is the relationship between structural damage degree and the intensity of a quake.
In engineering and scientific practice, often adopt response spectrum that criterion recommend for task spectrum, but a(x) phase information is provided by random phase angle φk in (0,2π) uniform distribution.

It exploits enterprise market by increasing range and share of products, collecting and analyzing market information, and constituting bid network of competitiveness, etc. (5) Engineering management.
Therefore, enterprise can profit from each engineering project.
Because of the concentration of funds, technology and management, they can win more engineering projects across different regions and countries.
They usually get subcontract business and engineering projects from the prime contractor.
