Avenir’s HeatCAD 2010 is the all-new CAD-based software for residential heat load calculation. Using HeatCAD, designers can quickly draw detailed floor plans from scratch or by simply tracing over imported AutoCAD, PDF or scanned drawing files. The room-by-room heat loss calculations are performed automatically and several report options are available to allow for easy review and submittal of work.
