Growthpoint portfolio

The certification work is world-class — 141 green building certifications and 12 net-zero buildings. This platform keeps every certificate alive: each property re-rated continuously from metering data already flowing, so the next EPC and net-zero submission is earned from live data instead of another audit cycle. Shown here for the 188 office and logistics & industrial properties listed on growthpoint.co.za — with their own photographs; retail and healthcare follow the same pipeline.

Synchronised control · condition for the people actually in the building

Occupancy from access control and people counters — HVAC, hot water and deferrable plant scheduled together with grid, max demand and rooftop solar in one control philosophy
PRECONDITIONING HEAT MAP · NEXT 24 Hwhen each system runs, when it preconditions, and the occupancy driving both — the building is pre-cooled 1–2 h before arrivals, never conditioned empty

Access control and people counters feed the same engine: HVAC ramps as tenants arrive, follows occupancy through the day, and winds down as floors empty. When rooftop solar is producing, deferrable plant runs solar-first; as the building approaches its notified maximum demand, staged loads back off automatically; hot water is shifted out of the evening peak.

How the certificate is produced

No manual assessment cycle
Metering API→kWh/m² · ℓ/m²→Energy + water rating→EPC generated & registered

Offices and other in-scope buildings receive SANEDI-registered compliance EPCs once occupancy class and boundary are confirmed; logistics and industrial facilities get clearly labelled voluntary EPC-principle benchmarks — all from the same automatic pipeline, at portfolio scale.

Green Seeds: the tenant cohort

Six properties compete on improvement against their own baseline. Tenants and building teams see their score on WhatsApp each Monday — no app download, opt-in under POPIA — and winning playbooks roll out cohort by cohort across the 388.
