Hybrid working and changing occupancy
Heating, cooling, lighting and ventilation can continue as though every floor were occupied.
Offices & Commercial Property
Reduce building costs around how the office is actually used.
Landlord, tenant and managing-agent responsibilities must be clear before procurement or building improvements begin.
A data-led sector review
The costs behind every working day.
Office buildings use electricity and gas across heating, cooling, ventilation, lighting, lifts, IT, server rooms, kitchens, hot water, security and EV charging. Hybrid working makes costs harder to control when systems still run for a workforce that is not there every day.
We analyse contracts, half-hourly use, occupancy and building systems before creating one plan across procurement, controls, efficiency and on-site generation, with occupier, landlord and owner responsibilities made clear.
Common offices & commercial property energy challenges
What needs attention.
Contract exposure, consumption and site constraints are assessed together.
Continuous baseload and demand peaks
Server rooms, IT, lifts, security, kitchens and overnight equipment create baseload, while HVAC and EV charging can add peaks.
Landlord, tenant and portfolio complexity
Leases, service charges, shared supplies, landlord duties and different renewal dates complicate decisions across a portfolio.
One plan across the operation
Supply, consumption and generation are connected decisions.
The right priority depends on the contracts, how the site is used, its infrastructure and future plans.
Commercial energy procurement
Compare electricity and gas contracts across individual offices or the full portfolio using actual consumption, dates and expected occupancy.
Monitoring, controls and efficiency
Identify unnecessary use across HVAC, lighting, IT, kitchens, hot water and equipment outside occupied hours.
Solar PV, storage and EV charging
Assess generation, storage and workplace charging against space, capacity, parking, property duties and expected return.
Our process
From site data to a clear plan.
Data first, priorities second, then delivery around the operation.
Understand the building
Collect bills, contracts, interval data, occupancy and details of HVAC, lighting and electrical equipment.
Set the priorities
Assess exposure, overnight baseload, controls, peaks, generation and efficiency with costs and savings shown.
Deliver and review
Coordinate work around working hours, tenant needs and access, then review as occupancy changes.
Our approach
Buy better. Match consumption to occupancy. Invest where it pays.
A lower unit rate will not correct an office heating, cooling or lighting unused space. Solar will not suit every leased property and replacing working equipment must have a justified return.
Buy better
Secure suitable contracts around consumption, renewal timing and portfolio requirements.
Match consumption to occupancy
Adjust heating, cooling, ventilation and lighting to genuine building use.
Reduce continuous baseload
Find IT, server cooling, kitchens, hot water and other overnight loads.
Generate and charge on-site
Assess solar, storage and workplace charging against property and demand.

Ongoing support
Contracts and improvements remain under review as occupancy and property needs change.
Offices & Commercial Property energy FAQs
Useful starting points for the sector.
How can offices reduce energy costs?+
Review supply contracts, match HVAC to occupancy, reduce overnight baseload, improve lighting controls and assess suitable on-site generation.
Can NUA Energy manage contracts across multiple offices?+
Yes. We can review meters, use, dates and supply arrangements across a portfolio while assessing each location's operating and lease position.
Can improvements be made in a leased office?+
Potentially. The lease determines responsibility and permission. Landlord consent may be needed, and the funding party should understand who receives the benefit.
Are solar PV and battery storage suitable for offices?+
Possibly, subject to ownership, roof condition, structure, network and actual daytime demand. Storage still needs a defined operating and financial case.
