Single-family + Suites • Per-suite Other Loads • Shared Loads (2+ suites) • PDF

Settings

Rows only count if USE is checked. Amps mode uses: amps×volts×mult. Watts mode uses the typed watts. Demand watts = watts×demand.
Other Loads now exists for: Main House + each Suite. And if you enable 2+ suites, a Shared Loads table appears.

Main House Basic Load (Your sqft method)

Basement factor • sqm/90 • ceiling to 1000
Total sqft = up + (bsmt × factor) → sqm = sqft ÷ 10.7639 → k = sqm ÷ 90 → basicW = CEILING( 5000 + (k − 1)×1000 , 1000 )
