Two programs from Avenir Software have been certified by the Air Conditioning Contractors of America as “Powered by Manual J.”

The trademarked designation means that programs comply with the standards and procedures contained in the ACCA’s Manual J, which covers residential HVAC load calculations. Avenir is now allowed to use the logo on the products.

Avenir’s HeatCAD covers residential heating and cooling load calculations and LoopCAD deals with radiant and snow melt systems.
