METHOD NOTES — Concept-stage estimator using simplified parametric models: wind speed by power-law profile v(h)=v₁₀·(h/10)^0.25; solar yield from climate insolation × roof PV area × 20% module efficiency × 0.78 performance ratio; rain harvest = roof area × annual rainfall × 0.9 runoff coefficient; EUI from compactness, envelope U-values, WWR, shading and smart-tier factors against an ASHRAE-style baseline. LEED v4 BD+C (110 pts), WELL v2 (100 pts) and Green Star Buildings (100 pts) scores are indicative pre-assessments, not certified ratings. Verify with dynamic simulation (energy, CFD, daylight) before design development.
