Each venue starts from a baseline daily load split across lighting, HVAC and AV equipment. LED adoption cuts the lighting load by up to 55%, and an HVAC retrofit (insulation, heat recovery, smarter controls) cuts heating/cooling by up to 45% — the ranges reported for real venue upgrades.
The rooftop solar array's instantaneous output follows the sun: P = P_peak · max(0, sin(π·(t−6)/12)) for daylight hours, visualised by the sun arc and the panels' glow. Daily generation is the peak capacity times ~5.5 equivalent full-sun hours. Grid draw is whatever consumption solar generation doesn't cover; CO₂ avoided uses a 0.4 kg/kWh grid-emissions factor.
- Bars on the right: live consumption for Lighting / HVAC / AV.
- Roof tiles light up proportionally to solar coverage and current irradiance.
