Manual J Residential Load Calculation 8th Edition

Manual J: Residential Load Calculation 8th Edition


Heating and cooling load estimates are part of a design procedure that moves from system selection to heat loss and gain calculations, to equipment selection procedures, to placement and selection of air distribution hardware, to duct routing and airway sizing or pipe layout and pipe sizing. Since the load calculation affects every aspect of the system design procedure, it must be as accurate as possible.

This Edition of Manual J applies to single family detached dwellings (site or factory built), low rise condominiums and townhouses and supercedes Manual J 7th edition with improved capabilities and sensitivities.
