Light steel structure residence is an optimum selection for the realization of building energy-saving and meeting of green building evaluation standards. Two kinds of system of light steel structure are analyzed and construction method for lightweight combination wall and infilled outer walls of low-rise light steel are summed up. Analysis on exterior wall conformation in low-rise light steel structure is put forward. Results indicate that special construct of light steel structure is equivalent to set closed air space, and thermal performance of infilled external wall of light steel structure is superior to that of traditional structure. And thermal performance of using aerated concrete wall panels as filled outer wall of light steel structure is better than that of aerated concrete blocks and thermal stability of filled external wall of light steel structure is better than lightweight combination external wall. The conclusions provide a theoretical foundation for building energy-saving in light steel structure residence and optimal design of residential environment.

Exterior insulation is currently promoting a building energy-saving insulation technology. Compared with internal insulation, it is a reasonable technique and has its obvious advantages. However, in the insulation material, thermal insulation effect is better, fireproof performance is often worse. Through analyzing several external wall insulation materials’ insulation and fireproof performance, the article recommends a kind of external wall thermal insulation material with good insulation and fireproof performance, to meet the construction needs.

Steel Consumption

Light steel keel structure is the most mature structure system in low-rise light steel structure residence. Exterior wall skeleton belongs to dense ribbed structure, so its thermal problems of exterior wall are more prominent. From light steel keel structure composition and exterior wall structure, based on the theory of thermal bridge, thermal performance of external wall is analyzed and thermal optimization measures of external wall in low-rise light steel keel structure are put forward. Specific measures are as follows: Firstly, finding the optimum balance point between the structure steel consumption and thermal performance; Secondly, punching in the steel skeleton webs to improve steel column; Thirdly, arranging the non-metal heat blocking between metal components; Finally, choosing external insulation system of outer wall. These measures are not only conducive to eliminate thermal adverse effects, but also can provide valuable theoretical basis for energy consumption analysis of low-rise light steel keel structure residence.

Optimum Insulation Thickness

External wall exterior insulation technology is one of the most common energy-saving measures in the existing residential building energy saving reform, after confirming the energy-saving standards, how to choose the optimum insulation thickness to make it the lowest cost of renovation in the life cycle is of great significance. Taking a dormitory building in Shihezi area as an object, we developed the mathematic model based on life cycle analysis for calculating the optimum insulation thickness. Finally we simulated the building with DeST-h and analyzed the economic.

In recent years, with the continuous development of society, people's awareness of energy conservation has also been enhanced. Among them, building energy consumption occupies a very large proportion in all their energy consumption. Therefore, people have taken various measures to reduce the energy consumption of building its own. External wall thermal insulation is a new building energy saving technology. Through verification, application of external wall insulation technology in building energy saving greatly reduces the energy consumption of buildings. This paper mainly introduced on the city building external wall thermal insulation technology and some related measures.
