Manual J Load Calculations & Manual S: Right-J ® is the industry leading residential load calculation software since 1986. It enables designers of all skill levels to perform ACCA and ANSI approved Manual J calculations quickly and with ease. Right-J ® also includes Manual S, with expanded data from some manufacturers, which automates the equipment selection process. Features: In conjunction with Right-Draw ®, Right-J ® will instantly calculate your load once building details are selected. Once the load is calculated, choose the desired equipment using the included (automatic or manual) Manual S feature. With our exclusive Hotlink™ technology, Right-J ® will recalculate instantly as you enter figures enabling you to play 'What If?'

Just by changing one value in the easy-to-understand worksheet. Use Right-J ® to: Build extensive libraries, or use our pre-loaded libraries. These libraries contain hundreds of building material types for building surfaces and offers the ability to create unlimited. Building material types already within the program range from standard frame materials to structural insulated panels, insulated concrete forms, log walls, encapsulated attics, sealed craws (spray foam/dense packed cellulose applications, and so much more.

This program can also can accommodate custom materials which can either be built as layers of components or entered with pre-engineered numbers and can be saved and reused. Easily assign air handlers as you need them. With our easy-to-use drag and drop multi-zone tree, choose to specify equipment type easily. Each space may have its own thermostat and can be grouped with other spaces simply by dragging from one piece of equipment to another within the multi-zone tree. Use any of 4 different infiltration systems. Right-J ® supports ACCA 5-option Simplified Method, ACCA Detailed Method, single point blower door (CFM-50), and multi-point blower door (Test-C / Test-N).

Calculate fresh air requirements using Manual J or ASHRAE 62 methods. Right-J ® supports centrally introduced and room introduced ERV, HRV, ventilating dehumidifiers, and untreated outside air. (ASHRAE 62 is required by Energy Star and other building codes and programs.) View the shape of load peaks and valleys. Right-J ® offers a colorful which shows the shape of load peaks showing you a large range of possible conditions effecting your load. These visuals are also shown on the Right-J ® reports. Add or view NFRC performance data. Right-J ® has dedicated fields to keep up with modern window technology.

Instantly set or find the worst-case-scenario house orientation. In a single click of a button, choose to view or print the load for every orientation on a single report.

Roquey from says, 'I have used Wrightsoft since the days of monochromatic screens and the spreadsheet-only format. I've attended several classes, been to the World Headquarters in Lexington, and even hosted training classes.

The level of support is phenomenal. Both in the classroom, call in and email. I've used the Right J, Right Draw modules extensively in the new construction markets not only for the purpose intended, but also to 'value engineer' the materials selection process for my clients. I can't imagine a better product.

The learning curve is pronounced and requires commitment on the part of the user, but with constant use it becomes almost second nature. As a 40+ year veteran of our industry, I highly recommend this company.' Al Gagne from Bayside Mechanical says, On our Training: 'I've been to three of your trainings over the last 7 years and every time I go I learn something new. The class provides a thorough understanding of Right-Suite ® Universal and helpful shortcuts so that I can continue to run my business effectively in this changing market.' On our Software: 'Wrightsoft’s Right-Suite ® Universal has helped us to turn bids around faster, especially for custom home builders.

I can simply import the AutoCAD building plans as a layer in the program, trace to complete the load calculations and add my ducts to the design, saving me a considerable amount of time. The full design and calculation is then saved in the AutoCAD file as another layer.' Jim Heinz President of says, “We are primarily a residential replacement air conditioning and heating company in Clearwater, Florida.

We found a serious issue with improperly sized air conditioning systems in existing homes that was causing issues with humidity, or lack of cooling. We have used Manual J for over 30 years, but due to the time-consuming process of entering information manually, it was not done unless we had a consumer complaint. We partnered with Wrightsoft over 15 years ago and can now do a Manual J Load Calculation in less than 30 minutes. Wrightsoft is always there for us, with tech support staff that answers the phone quickly, and offer advice when needed.

There is also a library of how to videos available 24 hours a day on their website. Wrightsoft has continued to be the best option for us for Manual J load calculations.”. Tim Kohut Director of Sustainable Design, says, “I reached out to technical support to complete an advanced task. Technical support responded within an hour or two, guided me through the process, and even QC’d my spreadsheet (making corrections needed). I was really impressed I’ve found that my questions are always answered, usually within hours, and there’s never an attempt to dodge an issue. Wrightsoft’s responsiveness on the support side is what truly sets you apart. Your team has made my life easier and using RSU has become an integral cornerstone to the work I do guiding our teams in the design and construction of high performance, soon to be ZNE affordable housing.”.

Steve Paxton from Air-Dynamics says, “I've been using Wrightsoft since the late 80’s. Public Service Company in Oklahoma's 'Good Cents' program required an ACCA Manual J load calculation and ACCA Manual D duct design to qualify as a 'Good Cents' structure. As long as the information is entered correctly, Wrightsoft takes all of the guesswork out of the equation. It has given me peace of mind and keeps our quality of installation above the rest. I can't imagine doing an install without it, it's as important to us as the rest of the tools on our trucks.”.
