DEMO · ILLUSTRATIVE DATA

RDC portfolio · one energy scale across Botswana, South Africa and Croatia

RDC's South African offices carry statutory energy performance certificates; Botswana has no certificate law; Croatia already issues EU certificates. This is what one scale across all three looks like when the rating is generated from metering data — held continuously, re-rated every month, water rated concurrently — so the South African renewals never become a project, the Botswana buildings are benchmarked on the same scale while power tariffs climb, and the solar on the roofs shows up in the number. Shown here for 50 properties from RDC's published portfolio; certificates, bands and dates are illustrative until RDC's own are connected.

Renewal status

South African certificates · the whole book, ahead of expiry

Every South African compliance certificate across RDC's published portfolio, with its expiry and its data-rated position today. Certificates are valid for five years; the ones issued between the 2022 push and the December 2025 deadline come due from 2027 to 2030. With metering connected now, each renewal is issued from data already flowing — no site campaign, no rush in the year they expire, and no five-year cliff after that. Botswana and Croatia carry no expiry: they are rated monthly on the same scale.

Renewal timeline

South African certificates expiring per half-year, 2027 – 2030 · red = the first window

Connect metering now and every renewal from 2027 is issued from twelve months of real data before the old certificate lapses — and the Botswana and Croatian buildings are rated from the same month.

Held continuously · one price per building, in every country

Per building per month · the South African renewal is included, and so is everything the data brings with it
R 1,000 per building per month · five metering points included · ≈ P 770 · € 50
  • South Africa: renewal certificate issued ahead of expiry, registered, display copy for the entrance — included
  • Botswana and Croatia: the same rating, same scale, refreshed every month — clearly labelled as voluntary, ready for a national scheme the day one exists
  • Solar PPAs read from the same meters, so the certificate shows what the roof actually contributes
  • Meter IQ cases routed to the responsible person with a value in local currency
  • Portfolio view for asset managers and the integrated-report line — energy, water and carbon per building, per country
  • Additional metering points R 50 per point per month

All certificates

Select a row to open the building · sorted by expiry
BuildingClassGLAOn fileRated todayIssuedExpiresStatus

Properties and GLA from rdcbw.com and RDC's 2025 prospectus (some areas estimated); bands and dates are illustrative until RDC's certificates and metering are connected. Occupancy classes per SANS 10400-A; compliance EPCs apply to qualifying buildings above the regulated size thresholds, voluntary benchmarks elsewhere.

Start with the rating. The rest switches on when RDC wants it.

The renewal is the entry point — and the same connected data is the first rung of a ladder RDC can climb building by building, tenant by tenant, in any of its markets. Nothing here is required for the renewals; every rung uses the metering already connected for the certificate.

What RDC gets from rung one alone

The renewal, done properly
  • Every certificate renewed ahead of expiry, registered, display copy issued
  • One live rating per building, energy and water, every month
  • A portfolio view for asset managers and the integrated report — energy, water and carbon per building, with the solar PPAs' contribution measured rather than estimated
  • Tenant-facing evidence: the number on the wall is this year's, not 2021's
  • No site campaign, no report chasing, no five-year cliff

The rules we keep

Written once, so nobody has to ask
  • Existing metering connected read-only; nothing replaced
  • Compliance EPCs only for qualifying buildings; voluntary benchmarks clearly labelled elsewhere
  • All savings stay 100% with RDC and its tenants — GreenX never takes a share
  • POPIA- and Botswana Data Protection Act-aligned, South African hosting for SA and Botswana data, EU-region hosting for Croatia, RDC as data controller
  • Certificates and data remain RDC's, whatever happens later

Next step

Before the first South African renewals fall due

Send the list of South African certificates on file with their expiry dates, and the metering in each building across all three countries. We map every property to its meters, mark which renew first, and come back with a connection plan — one price per building, nothing once-off, one scale from Gaborone to Zagreb.
