Dial in glass type, frame system, cavity fill, and spacer. The four performance metrics — U-value, SHGC, VT, and air leakage — recalculate in real time and check against BC Step Code 3 / 4 / 5 hard targets. SHGC is shown as an informational design input; the Step Code doesn't prescribe a strict SHGC range. Recommended Catalyst products at the bottom update with the spec.

These three are checked as pass/fail. Step 3 / 4 / 5 set increasingly stringent maximum U-values and air-leakage limits, and a minimum VT for daylighting. Colder climate zones tighten the U-target further (zone 7 subtracts 0.20 from the baseline).
The Step Code does not prescribe a strict SHGC range. SHGC feeds the energy compliance model (HOT2000, NECB), not pass/fail. Lower SHGC favours cooling-dominant facades; moderate SHGC helps with passive winter heating. We surface it as a suggested range, not a hard target.
