Description

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
