In 1985 at the Massachusetts Institute of Technology (MIT), Bill Wright was giving a graduate seminar on heating, ventilation, and air conditioning (HVAC) when he was approached by the Air Conditioning Contractors of America (ACCA). The largest organization of HVAC contractors in the United States, the ACCA wanted to work with Wright to develop a software program to run calculations for HVAC designers. And, so, WrightSoft was born. Still the leader in HVAC design software, it now produces many software programs to aid in HVAC design. But its first product, a Manual J load calculator, is still its flagship product. If you want to calculate a load using Manual J, then it’s your best bet to look for a WrightSoft Manual J compliant designer.
In order to become a WrightSoft Manual J compliant designer, candidates must undergo rigorous training. They must not only learn how to use WrightSoft programs themselves, but they must also learn how to clearly explain these programs and their use to others. This is because it’s of vital importance not only for the designer to understand his own design, but also for the contractor to understand what the design is intending to accomplish and why. That way, he’s not just a robot following a plan, but a human being with common sense who can recognize when something in the plan is awry.
The job of a WrightSoft Manual J compliant designer is not just to help design HVAC systems, but also to come up with solutions to problems. If it was just a matter of using the software, anyone with a basic understanding of computers could simply punch in data and crank out load calculations all day. But the key is that the designer knows how to design, and how to come up with creative solutions to common problems.
Not only should the WrightSoft Manual J compliant designer be familiar with WrightSoft’s Manual J calculator, but with other WrightSoft software as well, such as Universal Residential v13.0, which combines calculation software with innovative sales, proposal, and equipment comparison software. The designer should even be able to coach the uninitiated on how to effectively use WrightSoft programs to help manage their business, even working with contractors one-on-one, if necessary. The usefulness of a designer certified to work with WrightSoft programs is boundless. And the engineering groups and companies that they work in are fortunate to have them in their midst.
