What Code Officials Need To Know About Hvac System Design Part 1 Load Calculations

What Code Officials Need To Know About Hvac System Design What is the load? the measure of energy the hvac system needs to add or remove from a space to provide the desired level of comfort. btu h. not the size of the hvac system. first piece of information needed. 12,000 btu h = 1 ton cooling. can be highly variable. Acca has developed a three part video series that aims to help code officials better understand the three main aspects of a proper residential hvac system design: a load calculation, selecting the appropriate equipment, and proper duct sizing. the basis for the videos are the code referenced acca manual j, manual s, and manual d.

As a result, 29 states require manual j load calculations* be performed to properly calculate heating and cooling loads for new residential construction (see section 403.6 of 2009 iecc and section 1401.3 of 2009 irc). with home energy partners manual j training you will be ready to comply with code requirements. click the map below to find out.

Why do we need to perform these calculations? there are at least two reasons why we need to perform load calculations: to size heating and cooling equipment (ideally, using acca manual s), and to design heating and cooling distribution systems (using acca manual d). neither manual s nor manual d can be used unless manual j calculations are. Total heating load (watts) = 98,990 btu hr ÷ 3.412 ≈ 28,996 watts (w) (negative because heat needs to be added). in this corrected example, with an outside temperature of 40°f and a desired.
