The production process and application of large composite external wall panels (composite panels for short) are introduced in this paper. Composite panels with both load bearing and thermal insulation were formed by pouring normal concrete (NC) and ceramsite foamed concrete (CFC) continuously according to particular technological requirements, which made two layers into a seamless whole. The layers of NC and CFC are for load bearing and thermal insulation respectively. The composite panels were manufactured in the scale of industrial production, and applied to several energy saving prefabricated buildings successively, instead of polystyrene sandwich composite panels (sandwich panel for short) as external wall panels. There are several obvious advantages of the composite panel over the sandwich panel or outer benzoic board. Firstly, it solved the problems of durability of polystyrene and the complex production process of the sandwich pane, the production process of the external wall was thus greatly simplified. In addition, the fire risk was much reduced.

The City

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.

Optimum Insulation Thickness

In Turkey, “Thermal Insulation Requirements for Buildings” was implemented to provide energy saving in buildings in 2000. After this, more then seven hundred thousand new buildings are constructed. Determining the correct material and optimum insulation thickness are very important issues in these buildings for thermal insulation. Calculations using monthly outdoor temperatures and solar radiation are done for XPS insulation material and 4 different climatic regions in Turkey. Natural gas, the most preferred in our country is selected as fuel. P1-P2 method is used to obtain energy saving and payback period. New correlations are specified to determine optimum insulation thickness depending on building heat gains and areas. Furthermore, buildings are categorized into three building class according to external wall area and floor/roof area. Effect of change in building external wall area, floor or roof area, window area to payback period, energy saving and optimum thickness are investigated. As a result, effect of architectural design is determined on thermal insulation. All calculation results are shown in a table for four different climatic regions and three different types of buildings which have the same gross volume.

Technique Evaluation

The current evaluation process of architecture external wall thermal insulation energy-saving has met the problems such as information incompleteness and fuzziness. In order to solve the problems, the fuzzy comprehensive evaluation method is used, and the external wall thermal insulation energy-saving technique evaluation index system is set. And the method is adopt to compare between the walls using and not using the technology. The result shows that the evaluation of the external wall using thermal insulation energy-saving technique is obviously better than the result of the external wall not using the technique, so the thermal insulation energy-saving material should be promoted and applied nation-widely.
