Sustainability and energy-efficiency solutions
Roof PV about 2.1 GWh/yr, 17 PV carports (476 kWp), SBC 601 envelope (U ≤ 0.34, SHGC ≤ 0.25), TSE irrigation, 26 EV charging and 52 EV-ready bays.
Answer
PV: 6,246 m2 of panels on the upper roofs and annex roof - 1.52 GWh/yr at 15 % efficiency, about 2.1 GWh/yr with 21 %-class modules (Forma; 10,409 m2 of roof receives about 2,000 kWh/m2/yr).
Envelope to SBC 601: walls U <= 0.34 W/m2K; low-E solar-control glazing (target SHGC <= 0.25, U <= 1.9 W/m2K); room WWR 36 %; khatam screens 35-45 % open on the west.
Water: water-efficient fittings, TSE-ready drip irrigation for 4,003.78 m2 of native planting. HVAC: central chilled water with heat recovery.
Surface parking: 17 PV carport canopies over 141 bays, 476 kWp, about 880 MWh/yr. EV: 26 charging bays (incl. 2 DC fast and 1 accessible) and 52 EV-ready bays (LEED LT c5).
