HVAC contractors use a Manual J calculation to determine the heating and cooling loads of a home or building, and recommend the capacity of HVAC equipment needed. It's one of the tools published by the Air Conditioning Contractors of America to help HVAC contractors design a heating and air conditioning system. A new online tool lets contracts complete the complex task in about a minute.
By using Manual J methodology, HVAC designers are able to accurately determine the total amount of heat that is lost through the exterior of a home during the cooler months, and the total amount of heat that is gained through the exterior of a home during the warmer months. Through a complex series of calculations and inputs, the HVAC designer is able to analyze all aspects of the thermal characteristics of every wall, floor, ceiling, door and window. In addition, an HVAC load calculation also takes into consideration other factors such as the home's geographic location, orientation to the sun, envelope tightness, duct leakage, lights and appliances. ACCA's Manual J even calculates the amount of heat and humidity that each occupant of the house will add to the interior of the home.
Manual J Calculations Are Used To Determine The Amount Of Heat The House Loses In Winter And Gains In Summer. Manual J: A/C Load Calculations may be done room-by-room for the whole house, which allows you to determine how much conditioned air, in cubic feet per minute CFM each room needs for both heating and cooling.

Understandably, properly performing a Manual J calculation can take some time.
A new tool developed by Distributor Corporation of New England (DCNE) promises to streamline the process of calculating home energy performance. The Cool Calc Manual J tool enables contractors to leverage the power of big data to measure a home’s HVAC needs before making a house call.
The tool is the result of two years of development by a team at DCNE. Launched earlier this year, Cool Calc is one of only seven products to earn the coveted 'Powered by ACCA Manual J' approval for full residential load calculation from the Air Conditioning Contractors of America, and is the only ACCA-approved Manual J calculator available free online.
It is fully compliant with ANSI/ACCA 8th Edition Version 2 and was featured at the ComfortTech trade show in St. Louis in September 2015.

Cool Calc uses advanced geospatial algorithms to process publicly-available Lidar data and Ortho imagery, allowing it to automatically detect a building’s footprint, wall area, ceiling area, floor area and exposures.
The software uses a home's property tax records and location to automatically select the building materials required to meet local building codes during construction. By combining the dimensional data with the material selection, a contractor can perform an ACCA-approved manual J in less than one minute.
“This tool is designed to help contractors serve customers more efficiently,” said Nancy Kolligian, DCNE President and Chief Executive Officer. “By leveraging technology, this product can lower the cost of new customer acquisitions. It’s not designed to replace site visits, but aims to create a more efficient home visit.”
A contractor or office administrator can use Cool Calc to perform a preliminary Manual J calculation prior to going out to a job site. They can then refine the results from a mobile phone or tablet right from the home, rather than starting from scratch.
Cool Calc is designed for technicians with varying levels of technical proficiency. The software is Web-based and uses a responsive design. It can be used on any Internet connected device. “Our goal from day one was to develop a product that requires no formal training,” said Kolligian.

Building codes require heating and cooling loads to be calculated with the procedures of ACCA Manual J.
“… building loads calculated in accordance with ACCA Manual J or other approvedheating and cooling calculation methodologies. “ IRC 2009 M1401.3
ACCA Manual J is the industry recognized method for determining heating and cooling loads which lead to proper equipment sizing. No more basing HVAC equipment size on “rule of thumb.” – The ACCA book on Residential Load Calculation (Manual J) is 556 pages long. It is filled with extensive numbers, equations, tables and worksheets.
After one flip through this tome, you’re thinking “just give me the bottom line.”
This type of procedure is perfect for computer software; let the computer do all of the number crunching. However, software from the top software vendors can be expensive; greater than $400 for basic Manual J Calculations.
An old computer adage is “Garbage in is garbage out.” ACCA will approve and certify that Manual J software follows the proper procedures. But an accurate load calculation involves a great amount of input. And that input must be accurate and appropriate. If these inputs are not known then defaults are used. Default is another term for guess. Manual J was meant to move away from guessing.

If the input information is just a guess (garbage in), you have just spent a lot of time and money on what you had before (garbage out). Same result if you don’t have a complete understanding of the inputted data and make a wrong determination. A few little inaccuracies are not likely going make a difference in equipment sizing. But where is the line.
Let me do your Manual J load calculations for you.
Use my 35 years of commercial and residential load calculating and building energy analysis to your benefit.
- No buying expensive software.
- No wasting hours of trying to understand input tables and charts.
I use my own worksheet based procedures, using the computer only to keep the math correct. This way I have full control over all inputted information and how it is used in the procedure. I can answer technical questions. Instead of saying “well that’s what the program says.”
