FAQ
Cape Town questions
Does GreenBDG work on Cape Town buildings?
Yes. Our live production pilot runs at Bertha House in Cape Town, and certification and monitoring programmes cover the Western Cape. Site work is scheduled in batches, the same way we run Gauteng portfolios.
What did the Bertha House engagement deliver?
A 2,000 m² Cape Town property cut energy use by 25%, saving around R 58 000 per month, and reduced carbon emissions by 38% over a 12-month engagement, with energy use intensity, Scope 2 and Section 12L metrics running in production on Sunsynk PV and eGauge sub-metering.
Do Cape Town buildings face the same EPC rules?
Yes. The EPC regulations are national: non-residential buildings over 2,000 m² need a displayed certificate regardless of province, and the City of Cape Town adds its own energy and net-zero ambitions on top.
