OIt is required to air condition a factory building (27mx 18mx4m). The 27m wall is type B and faces south. The following data is available: Two glass windows in south wall 3mx 1.5m each with internal shade, lighting load is 20 Watt fluorescent per m² floor area. The inside air conditions are: 24°C DBT and 50% RH. The outside air conditions are: 40°C DBT, DR=18.0°C and 30°C WBT. Other related data are: Uwall=1.4 W/m² K, Uglass 3.5 W/m² K, Scglass-0.7, occupancy=8 persons doing light bench work and CLF occupancy=0.85. The building is of heavy construction with light color located at 40°N. Calculate the building cooling load from the South wall, windows, lighting and occupancy on August at 4:00 p.m.
