Bishops campus portfolio

One campus in Rondebosch since 1849 — Pre-Prep, Prep and College, with boarding houses that never sleep. Every building rated for energy and water from the metering data already collected: compliance EPCs generated and registered automatically for qualifying instruction buildings, water rated concurrently.

Synchronised control · heat and cool for the school day

Occupancy measured from access control, with the timetable as forecast — geysers, classroom HVAC, kitchens and the pool scheduled together, item by item

PRECONDITIONING HEAT MAP · NEXT 24 Hwhen each item runs, when it preconditions, and the occupancy driving both — classrooms pre-cooled before the first bell, the pool pre-heated on the solar window ahead of afternoon sport

Each geyser bank, HVAC zone and kitchen circuit is controlled at item level. The timetable is the forecast: classrooms are cool when the first bell rings and wind down as classes empty; geysers heat ahead of sport and aftercare, not all day; the pool pre-heats 2–4 hours before the afternoon session while the sun is paying for it. On weekends and school holidays the pre-heat is simply skipped — and that skipped heating is where much of the saving lives.

No manual assessment cycle

Qualifying instruction buildings receive SANEDI-registered compliance EPCs; nursery, aftercare and sports buildings get clearly labelled voluntary EPC-principle benchmarks — all from the same automatic pipeline, at group scale.

Green Seeds: the inter-campus cohort

Six campuses across four provinces compete on improvement against their own baseline. Learners and staff see their score on WhatsApp each Monday, eco-clubs drive the challenges, and winning playbooks roll out to the next cohort — the path to all 180+ campuses.
