An enterprise approach to energy & sustainability.
Energy and carbon are now investment-grade metrics. CRREM glide paths, GRESB scores, SFDR disclosures and tenant net-zero commitments all run on operational data — and the gap between disclosure and delivery is where most portfolios sit today.
Crown's Energy & Sustainability team closes that gap. We instrument the asset, build a verifiable baseline, identify and execute opportunities, and report savings using IPMVP protocols that withstand investor and auditor scrutiny.
Crown's Energy & Sustainability practice helps owners reduce consumption, decarbonise their portfolios and meet investor ESG commitments — through metering, analytics, operational optimisation and structured capex programmes.
Operational energy is typically 30–40% of a building's controllable opex and ~80% of its operational carbon. Reducing it protects net operating income, defends valuation against CRREM stranding risk, and satisfies the ESG commitments owners have made to their investors and tenants.
We sequence no-cost operational optimisation first, low-cost interventions second, and capex programmes third — each tied to a measured and verified business case. Every kilowatt-hour saved is traceable to a specific change and a specific evidence trail.
