Manual J
The Manual J load calculation procedure is used to determine the heating and cooling loads of buildings and homes.
Manual S
Manual S ensures your heating and cooling equipment is properly sized and will maintain its design comfort conditions.
Manual D
With ACCA’s Manual D, you’ll achieve occupancy satisfaction through the design of your HVAC system.
Manual J
Load Calculation
The Manual J load calculation procedure is used to determine the heating and cooling loads of buildings and homes. This procedure includes both the theoretical design load calculation, as well as a verification test calculation to ensure that the design load calculation provides an appropriate level of comfort. The HVAC engineer or the homeowner uses the results of this Manual J calculation to determine what size of heating, ventilation, and air-conditioning (HVAC) system should be installed in the building.
Manual S
Equipment Selection
ACCA Manual S is an essential part of the HVAC sizing process. Whether you are installing new systems or replacing existing ones, this manual is a valuable tool that has been developed to help you maintain the proper energy efficiency and comfort in your home. Cooling equipment should be sized within 115% of the total cooling load. Heating equipment should be sized within 140% of the peak heating load requirement.
Manual D
Duct Design
With ACCA’s Manual D, you’ll achieve occupancy satisfaction through the design of your HVAC system. This procedure is recognized by professionals, and for good reason: it takes into account how many cubic feet per minute of conditioned air you need for each room, what equipment you’re using, and how you plan to distribute this air. Once you know these details then you can carefully design the duct system to fit within your budget, your building code requirements, and typical HVAC limitations.
