The table below indicates human sensible and latent heat. The values can be used to calculate heat loads that need to be handled by air conditioning systems.

Typical Application	Sensible Heat (btu/hr)	Latent Heat (btu/hr)
Theater-Matinee, Auditorium,	200	130
Theater-Evening, School	215	135
Offices, Hotels, Apartments	215	185
Retail & Department Stores	220	230
Drug Store	220	280
Bank	220	280
Restaurant	240	310
Factory - light work	240	510
Dance Hall	270	580
Factory - moderate work	330	670
Bowling Alley	510	940
Factory - heavy work, Gymnasium	510	940

Tabulated values are based on 78^oF (25.6^oC) for dry-bulb temperature
Adjusted total heat value for sedentary work, restaurant, includes 60 Btu/hr (18 W) for food per individual (30 Btu/h (9 W) sensible and 30 Btu/h (9 W) latent heat).
For bowling figure one person per alley actually bowling, and all others as sitting (400 Btu/h) (118 W) or standing (550 Btu/h) (161 W)
