Theme A: Connecting the Pearl River Delta RegionA normal single glass with thickness of 3 mm, heat transfer coefficient (U) valueof 5.7 W/(m 2·k) and shading coefficient of 0.93 (DEST-H building materialslibrary).B- Building with Insulated wall: it has two layer reinforced concrete (5+5 cm),which separated by a insulation layer of polystyrene with 4 cm thickness and thethermal conductivity of 0.047 W/(m.ºC) [2]. In addition, the wall has a thin layerof gypsum mortar and plaster for inside. Fig.4 shows the details of suggestedinsulated wall. The experiences show that the construction cost for hollow blockwall and insulated wall is the same.C- Building with Double glass windows: we just used of normal double glasseswith 3+6+3 mm thickness instead single glasses in the windows of block wallbuilding. The U value of normal double glass was 3.4 W/(m 2·K) and its shadingcoefficient was 0.90 (DeST-h building materials library). The construction cost ofdouble glass windows is approximately 10 $/m 2 higher than one layer glasswindows in the previous methods (A & B).Figure 3: Details of the block wall.116
