TABLE B102 Acceptable Occupancy Densities, Receptacle Power Densities and Service Hot Water Consumptiona
Building Type | Occupancy Densityb ft2/Person (Btu/h . ft2) | Receptacle Power Densityc, Watts/ft2 (Btu/h . ft2) | Service Hot Water Quantitiesd Btu/h per person |
Assembly | 50 (4.60) | 0.25 (0.85) | 215 |
Health/Institutional | 200 (1.15) | 1.00 (3.41) | 135 |
Hotel/Motel | 250 (0.92) | 0.25 (0.85) | 1,110 |
Light Manufacturing | 750 (0.31) | 0.20 (0.68) | 225 |
Office | 275 (0.84) | 0.75 (2.56) | 175 |
Parking Garage | NA | NA | NA |
Restaurant | 100 (2.30) | 0.10 (0.34) | 390 |
Retail | 300 (3.07) | 0.25 (0.85) | 135 |
School | 75 (3.07) | 0.50 (1.71) | 215 |
Warehouse | 15,000 (0.02) | 0.10 (0.34) | 225 |
aThe occupancy densities, receptacle power densities, and service hot water consumption values are from ASHRAE Standard 90.1-1989 and addenda. |
bValues are in square feet of conditioned floor area per person. Heat generation in Btu per person per hour is 230 sensible and 190 latent. Figures in parenthesis are equivalent Btu per hour per square foot. |
cValues are in watts per square foot of conditioned floor area. Figures in parenthesis are equivalent Btu per hour per square foot. These values are the minimum acceptable. If other process loads are not input (such as for computers, cooking, refrigeration, etc.), it is recommended that receptacle power densities be increased until total process energy consumption is equivalent to 25 percent of the total. |
dValues are in Btu per person per hour. |
