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.

|
Cooling Load Calculations
The MJ8 Edition provides calculation of both heating and cooling loads
for residential applications. Full support for Manual J 8th Edition including block
loads, room-by-room loads, infiltration and ventilation loads, detailed exposure
diversity analysis, and room CFM estimates.

ACCA®-Approved Manual J®
HeatCAD MJ8 is ACCA-Approved for Manual J (8th Edition) residential
heating and cooling load calculations. This streamlines the acceptance of your submittals
by local authorities requiring ACCA-Approved software calculations. Click here for more
details.

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.
