Built on Standards
Engineers Trust.

Every assumption is visible, every value is editable. HVAKR starts with ASHRAE and ACCA defaults, then gets out of your way.

ASHRAE ACCA

Space Types

Indoor design temps, ventilation rates, lighting, and equipment loads are all pulled from ASHRAE 62.1 by space type.

Space Types

Import From Industry Standards

Start from ASHRAE 90.1 and 62.1 tables or your firm's saved templates. Filter by climate zone, project type, and standard year.

Import From Industry Standards

Wall Types

Assemblies, U-values, and absorptance for every wall, roof, slab, and fenestration type in your project.

Wall Types

Override Any Values at Your Discretion

Every number is editable. Change a design temp, swap an assembly, adjust a ventilation rate. HVAKR recalculates your loads instantly.

Build Your Own Library

Convert any project into a reusable template. Your wall types, space types, and schedules carry forward.

Build Your Own Library

Full Control of the
Entire Engineering Process.

Draw, split, merge, and reshape spaces directly on your floor plan. Every edit recalculates loads and square footage instantly.

Architects Throw Curve Balls.
You Hit Home Runs.

When plans change, HVAKR instantly updates. New floor plans? Windows moved to east side? Load calcs are automatic.

@HVAKR Support Hey, I'm getting an error when I try to export the ventilation report for my school project. Any ideas?

Hi Marcus! I just pulled up your project. Looks like one of the zones is missing an outdoor air assignment. I've flagged it. Try the export again and let me know!
