For engineers

Cited answers for the calc you are about to stamp.

Structural, mechanical, electrical and energy-modelling engineers use CodesWise to verify code-driven inputs against the actual NBC, NECB, NFC, and the CSA / ASHRAE standards the codes adopt by reference.

What it actually changes

You are sizing a beam, picking a fire rating for a column, or modelling envelope performance. The deciding constraint is buried in NECB Section 3.2 plus a CSA standard adopted by reference. You need the clause, the table, and the exception, in seconds, not in twenty minutes of search.

Where CodesWise earns its keep

Structural code lookups

Wood post unsupported height, concrete cover requirements, rebar size and spacing for 200 mm foundation walls. Cited and dual-unit (mm + inches) on every answer.

Energy compliance (NECB 2020 / 2025)

Climate-zone-specific R-values, HRV efficiency thresholds, fenestration limits, building envelope trade-offs. Search across NECB, the NECB Illustrated Guide, and the ASHRAE 90.1 standard adopted by reference.

Referenced standards

When the NBC sends you to CSA A23.3 for concrete or CSA O86 for wood, CodesWise indexes those documents alongside the code so the trail does not break.
