Manual N 5th Edition Commercial Load Calculation

The Air Conditioning Contractors of America (ACCA), the nationwide association of heating, ventilation, air conditioning, and refrigeration contractors, has released a completely revised version of "Manual N," the industry standard for calculating heat gain and heat loss for light commercial buildings. The new fifth edition of "Manual N" represents the first complete rewrite of the light commercial load calculation procedure in over two decades, addressing the many advances and changes in the construction industry that have taken shape, such as new materials, methods of assembly, and operational requirements. Authored by Hank Rutkowski with the oversight of a dedicated committee comprised of representatives from across the HVACR industry, the fifth edition of "Manual N" provides instruction to help contractors and designers satisfy new (and often conflicting) energy, ventilation, and comfort requirements for light commercial buildings.
