HAP AnalysisMethodology

Proper U-value calculation of surfaces

Lighting Load: 1.0 W/sq.ft.

Occupancy ~ 10 people

Evaporation load of pool (2003 ASHRAE HVAC Applications)

wp = 0.1A(pw - pa)Fa = 2.499 lb/h

Btuh = wp * 45Btu/lb = 112.5 Btuh (latent load)

Where:

pa = saturation pressure at room air dew point

pw = saturation vapor pressure taken at surface water temperature

Fa = 0.65, Condominium Pool Water Temperature = 80 F

Dry Bulb Air Temperature = 78 F % Relative Humidity = 55
