This app allows you to perform detailed block and room-by-room heating and cooling loads for residential buildings out in the field, by taking advantage of the simplicity, power, and screen-size of the iPad.

This app was designed by Carmel Software Corporation, a 25-year old software design firm specializing in engineering analysis software applications. We are not just 1 person designing mobile apps out of a bedroom. We are a team of software developers with over 50 years combined software and engineering design experience. In fact, our software powers the analysis capabilities of major Autodesk software tools such as Revit (The makers of AutoCAD). Also, we provide full support including phone, email, and periodic live webinars.

The following is just a small sample of the features included in this app:

1. Calculations based upon ACCA Manual J8 Abridged calculations
