The Residential HVAC Load-J Calculator app developed by Carmel Software for MEUS is an ACCA-approved Manual J8 residential load calculation app for the Apple iPad. It allows engineers, contractors, and technicians to perform field-based cooling and heating load calculations on residential and small commercial buildings. Users are then able to email PDF reports to customers and local building officials. Reports produced by this app will be acceptable by all municipalities/states (including Florida and Massachusetts which recently passed laws requiring contractors to submit load calcs from ACCA-approved software.)

The Residential HVAC Load-J Calculator app allows users to create unlimited projects and perform both block and room-by-room loads. The app includes weather data for 1000s of cities throughout the world and construction data for 100s of wall, floor, roof, ceiling, and window types. The user is also able to model detailed appliance, duct, infiltration, and ventilation loads.

The Residential HVAC Load-J Calculator app was specifically designed for the Apple iPad, taking advantage of the larger screen, rotating user interface, and other functionality unique to the iPad.

Other features include:

1. Includes a 1000+ world-wide city weather database

2. Allows you to create and store an unlimited number of projects. You can also re-use existing projects as templates for new projects.

3. Includes data for 100s of construction types for walls, roofs, floors, doors, windows, skylights, and ceilings.

4. Allows you to specify an unlimited # of building envelope types (i.e. – doors, walls, roofs, floors, ceilings), window types, and skylight types for each building.

5. Allows you to input individual home appliance information.

6. Allows you to instantly view total heating and cooling load results as you update input data.

7. Allows you to view comprehensive cooling and heating load breakdown reports including breakdown by envelope load, window load, skylight load, infiltration load, ventilation load and internal load contributions.

8. Also performs room-by-room cooling and heating load calc analysis

9. Includes the ability to display a wide variety of on-screen reports including checksum reports (ie – BTUh/SqFt, SqFt/Ton, etc.), complete heating and cooling load breakdown reports, and even graphically-pleasing pie charts showing cooling and heating load breakdowns. These reports can be converted to PDFs and emailed from right within the app.

10. Includes the ability to display a comprehensive HTML report that you can email to yourself or others, and it also includes a spreadsheet attachment that you can open in Excel to create customized reports.

11. Includes the ability to display units in either English (IP) or Metric (SI).

The benefits of using this app are numerous including:

1. Great for use out in the field. Quickly size heating and cooling equipment, show the client, then email the results back to your office for further analysis.

2. Show off your advanced on-screen reports to clients convincing them you are using cutting-edge technology.

3. Save time by inputting information in the field and then returning to your office to perform more in-depth analysis.

4. Submit reports to local municipalities that require ACCA-approved Manual J8 residential load calcs for equipment replacement.
