QUICK TIPS

HeatCAD 2016

The North Arrow can be used to specify your building orientation, which is critical for cooling load calculations. You can automatically find the orientation with the maximum cooling load if needed.

HeatCAD® 2016

HeatCAD 2016 is a drawing-based software for fast and accurate calculation of residential heating and cooling loads. The Standard Edition supports ASHRAE and CSA residential heat loss calculations. The MJ8 Edition provides ACCA®-Approved Manual J® (8th Edition) calculations for residential heating and cooling loads (more on Manual J...). HeatCAD delivers advanced design features including integrated load calculations, automatic detection of unheated surfaces, and 3D CAD views. Try it now free for 30-days.

Floorplan Drawing
Creating floorplan drawings is very fast using the predefined rooms, doors, windows and other objects. Rooms can be resized by dragging the walls or corners, and they are easily docked together to create complex floor plans. The room shapes can be quickly edited to create very complex shapes, and you can also use the freehand drawing tools to create more complex shapes. HeatCAD also allows you to import an existing AutoCAD*, PDF** or scanned drawings to use as a template.

Heat Loss Calculations
HeatCAD calculates the room-by-room heat loss automatically as you draw the floorplan. And you can choose the residential calculation method that best suits your project – ASHRAE, CSA or Manual J. HeatCAD automatically detects rooms above or below and even supports cold partition calculations between rooms.

3D CAD Views
HeatCAD generates 3D views of your building that you draw in 2D. The new 3D views are a powerful aide for ensuring accurate heat load calculations, and are also very effective for communicating your design work. Validation of the placement and sizing of windows, doors and walls is made much faster and more precise with the 3D views.
