Energy modeling for complex built environments.
CHAAC delivers rapid-turnaround ASHRAE 90.1, IECC, LEED and Title 24 modeling for commercial and multifamily developers who cannot afford permit delays. Precision data, engineered for speed.
Permitting shouldn't be the bottleneck.
Inaccurate energy modeling triggers RFI cycles that stall projects and erode developer margins. CHAAC removes the friction between architectural intent and regulatory reality — so your team stays on schedule.
