CALCULATION SHEET
Space used for office : 27 m 17 4 1836
Effective Room Sensible Heat
S/No Type of load Load (W)
1. Sensible solar heat gain through window glass W
2. Solar transmission gain- walls and roof W
3. Transmission gain- Others W
4. Internal heat gain W
Room Sensible Heat Load Calculation
1. Sensible Solar Heat gain through Wind
Item Area (m2) Solar heat gain / m2 (W) Load (W)
