Abstract
With the aggravation of global environmental pollution and energy crisis, more concern has been focused on green ecosystem. As an important part of energy saving and pollutants discharge reduction, great importance has been attached to architecture energy saving in the field of architectural design. Accordingly, many new types of energy-saving materials and techniques emerged, the double facades building is the offspring against this background.
Double skin facades can bring beautiful architecture outline, comfortable indoor environment and good effect of energy saving. Nevertheless, the design of double skin facades is a complicated job which needs to consider many factors synthetically. If only we know its energy saving performance, we can correctly design a system of double skin facades meeting the local climate well. Because of the variety and complexity of its effect factors, the domestic study of double skin facades is still at the stage of start. The reference documents about it are not enough so that double skin facades are not widely used in our country. So it is necessary to know its performance of energy saving well by study, then we can provide reference to engineering designers and evidence for the establishment of the criterion concerned.
The main results from this paper are as follows:
rocess of the design of double skin facades, a variety of factors should be considered. With this method, the optimal design of double skin facades can be got, and the workload can be reduced also.
2. The fire would spread along the walls with the air while the double skin facades get fire. And it is difficult for the fire rescue, so the corresponding measures should be taken.
3. A complete system of automatic fire facilities should be settled up with the design of double skin facades, and it is important to improve the fire safety.
It is quite important and urgent for the study on double facades building, which will have much effect on ensuring the fire protection safety of this kind of building and promoting its practical application. A basic study has been offered to hope the paper could as a reference for design, construction, management, and its development.
