Design Concept
The Bangkok climate, showing high air temperatures and solar radiation leads to enormous solar gains and, therefore, to high cooling loads and low comfort because of high operative temperatures in highly transparent buildings. The optimization process for the membrane roof construction and the glazing leads to a highly reduced solar transmission and, therefore, to low solar induced cooling loads in the concourses of the New Bangkok International Airport. Table 2 shows the material properties and basic assumptions. Table 4 shows the solar radiation, long wave radiation and air flows between zones. Table 4 shows the internal loads
