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. 120 pp.
Topics include:
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
