After your initial architectural design is complete, you should get an ACCA Manual J calculation early on in your HVAC design process. It should be done before any equipment is chosen because its conclusions will help inform how to choose equipment size and capacity when it is used in Manual S.
Manual J calculates a building’s heat loss or gain under the coldest and hottest conditions, respectively, by considering the building’s following attributes:
As soon as you know your Manual J results, you can move onto ACCA Manual S. This calculation matches those Manual J results with correctly sized HVAC equipment that will have the right heating and cooling capacity for your needs. Heating capacity is the amount of heat potentially produced by your heating system under the coldest likely conditions, whereas cooling capacity is the amount of heat your cooling system can remove from your home under the hottest likely conditions.
Your Manual S results are important because oversizing your HVAC equipment can lead to problems such as:
The same way Manual S takes into account Manual J’s results, Manual D needs the results of both Manual J and Manual S to be effective. This is the last manual of the three to be completed. ACCA Manual D will give you information to determine the right duct size and layout needed for air to be effectively moved throughout your home into your various rooms. It should be performed prior to beginning construction.
Manual D takes into consideration:
If you don’t get a Manual D duct design calculation, you’ll likely experience air and energy leaks from your ducts. Your home’s heating may also be uneven, with hot and cool spots in different rooms. This is because if the ducts are not correctly sized the air won’t be able to move properly from your HVAC system into the desired living spaces. Finally, incorrectly sized ducts contribute to wear and tear on your system, since it will have to work harder to get the air where it needs to go.
