Sustainability
Verified standards, by the IFC.
EDGE is the International Finance Corporation’s standard for resource-efficient buildings. It is third-party audited. It is independent of the developer claiming it. We pursue it on every project because it converts good intentions into measurable outcomes.
What EDGE is
A 20% threshold, audited.
To be EDGE-certified, a project must reduce energy use, water use, and the embodied carbon of construction materials by at least 20% against a local baseline. The local baseline is defined by the IFC for each market.
The audit is performed by a licensed third-party assessor. The developer cannot self-certify. The certificate is granted in two stages: preliminary (at design) and final (after construction). Both stages are public.
Verified standards
CPH preliminary results.
IFC EDGE — preliminary certified
Energy savings
32%
Achieved through orientation, glazing, solar PV array, and high-efficiency MEP.
Water savings
38%
Low-flow fittings, dual-flush WCs, rainwater harvest for landscape.
Embodied material
41%
Local granite, recycled-content steel, certified-source timber, lime plaster.
Versus the Nairobi baseline
What the corridor builds, what we build.
Most premium developments in Nairobi do not pursue third-party certification. The IFC EDGE baseline for the city assumes a glass-curtain, single-glazed, mechanically-cooled mid-rise — the dominant typology. Our reductions are measured against that baseline. The audit methodology is published below; we link to the IFC source rather than summarising it.
