ASHRAE 90.1 Mechanical Compliance Check

AI-powered ASHRAE Standard 90.1 — Energy Standard for Buildings compliance checking for mechanical construction drawings. Detect violations, missing requirements, and code compliance issues before they delay your permit or hit the field.

About ASHRAE Standard 90.1 — Energy Standard for Buildings

The ASHRAE energy standard for commercial buildings, widely referenced by the IECC and many state energy codes. Covers building envelope, HVAC, service water heating, power, lighting, and renewable energy requirements.

Scope

Energy efficiency for commercial buildings (non-residential and high-rise residential)

Editions

ASHRAE 90.1-2022, 2019, 2016, 2013

Applicability

Referenced by the IECC as a compliance pathway. Adopted directly by some states and federal agencies (GSA, DOD).

What We Check For

HVAC equipment minimum efficiency per ASHRAE 90.1 Section 6
Economizer requirements per Section 6.5.1
Energy recovery ventilation requirements per Section 6.5.6
Fan power limitation per Section 6.5.3
Hydronic system variable flow requirements per Section 6.5.4
Simultaneous heating and cooling limitations per Section 6.5.2

Common Mechanical Issues We Catch

HVAC, exhaust, ventilation, and refrigeration drawings.

Energy code compliance — equipment efficiency and controls

Why ASHRAE 90.1 Mechanical Compliance Matters

ASHRAE Standard 90.1 — Energy Standard for Buildings compliance for mechanical drawings is critical because violations discovered during plan review delay permits, and issues found during construction result in costly rework, change orders, and schedule delays. Catching ASHRAE 90.1 mechanical issues during preconstruction costs 10x less than fixing them in the field (CII, 1-10-100 Rule).
