Onsite Energy & Efficiency for Commercial Buildings
Office parks, retail units and mixed-use assets face tightening EPC obligations, occupier pressure for lower service charges and growing demand for green credentials. We deliver data-led energy strategies that address all three.
Mixed loads, high occupier expectations
- Mixed HVAC, lighting and plug loads that vary significantly by floor and occupancy
- EPC minimum standards and MEES obligations requiring measurable improvements to retain lettability
- Occupiers demanding lower service charges and verifiable green building credentials
An EPC uplift that protects lettability
MEES keeps raising the minimum EPC a commercial space needs to stay lettable. A combined package of generation, heat decarbonisation and controls can move an asset several bands — clear of the standard rather than scraping it.
Commercial buildings — office parks, multi-let retail and mixed-use assets — face a compound set of energy pressures. MEES regulations progressively raise the minimum EPC standard required to let a commercial space. Occupiers increasingly factor energy performance and ESG credentials into lease decisions. And with energy a major component of service charges, landlords face direct commercial pressure to reduce consumption and import costs.
The challenge is that commercial buildings carry a wide range of loads — HVAC, lighting, catering, IT and plug loads — that vary significantly between tenants, floors and times of day. A one-size-fits-all intervention rarely delivers the best return across a diverse portfolio.
We start from the building's consumption data and occupancy profile to identify where generation, storage, heat decarbonisation and controls deliver the strongest combined return on energy cost, EPC rating and occupier value.

When EPC obligations meet rising occupier expectations
Commercial buildings face pressures that are regulatory, commercial and competitive at the same time.
EPC & MEES obligations
The commercial MEES minimum standard is rising. Assets that do not comply cannot be let, affecting both income and valuation.
Service charge pressure
Energy is a major service charge component and occupiers are pushing back. Landlords who cannot demonstrate cost reduction are losing tenant confidence.
Occupier ESG demands
Major corporate tenants include building energy and carbon performance in their lease criteria and ESG reporting — and are prepared to pay a premium for a building that helps them meet their targets.
Mixed, variable loads
Diverse tenants and occupancy patterns make accurate demand profiling essential. Generic modelling frequently overestimates returns.
Recommended technology stack
We combine generation, heat decarbonisation and controls to address MEES, service charge and ESG together.
Solar PV
Rooftop arrays that offset landlord-supplied common-area power, reduce service charges and contribute to EPC improvement.
