Set up a table showing the individual load components and calculate the total load in Btu/hr-ft2
Consider an office building of 7,680 ft2 floor area and 76,800 ft3 volume in Phoenix, AZ. The outdoor temperature is 110 0F. The room is kept at 720 F and the solar heat gain thru the window is 85,000 Btu/hr. The gross areas and the overall U values of each element are given below:
- wall: 3440 ft2 and 0.30 Btu/hr-ft2- 0F
- window: 576 ft2 and 0.60 Btu/hr-ft2- 0F
- door: 160 ft2 and 0.64 Btu/hr-ft2- 0F
- roof: 7680 ft2 and 0.15 Btu/hr-ft2- 0F F
- infiltration: 0.8 air changes per hour
Also the internal loads are specified as:
- lighting power density: 1.2 W/ft2
- Plug and equipment load density: 0.8 W/ft2
