Product Details

Manual N gives you a faster way to estimate heating and cooling loads for small and mid-size commercial structures, a simplified version of the procedure in the ASHRAE GRP 158 Load Calculation Manual. Manual N shows you how to use the Cooling Load Temperature Difference (CLTD) method to estimate heat gain through opaque surfaces and the cooling-load-factor method to estimate solar gains through glass.

– Basic principles of heat transfer, R-values, U-values, and heat transfer multipliers

– Calculating loads for individual structural components, rooms, and zones

– Time-of-day calculations

– Peak room loads versus peak block loads

– Indoor and outdoor design considerations

– Sensible and latent internal loads

– Wall, roof, ceiling, and partition heat gain and loss

– Heat gain and loss from glass, ducts, infiltration, and ventilation

– Humidification loads
