Commercial · Energy Management · London
You cannot managewhat nobody metered.
Most commercial buildings have one meter, one bill, and no idea which floor, tenant or machine the money went to. We install energy management that measures per zone, manages the peaks, shifts the flexible loads to cheap hours — and keeps every reading locally, with no subscription.
The Method
Measure, attribute,manage, shift.
In that order, deliberately. Optimising a building you have not measured is guesswork with a nicer dashboard.
Measure
Meters on the incomer and the loads that matter — HVAC, lighting, kitchens, server rooms, tenant areas — over Modbus or M-Bus, logged locally, forever.
Attribute
Consumption split per floor, zone or tenant, so a service-charge line or an ESG figure is a report rather than an argument.
Manage
Load management keeps the building inside its supply capacity, staging flexible loads instead of tripping or paying for a bigger connection.
Shift
Hot water, EV charging and other movable loads run when energy is cheapest or the solar is producing — automatically, against the tariff.
What You Get
From one mystery billto numbers you can defend.
Metering & sub-metering
- Electricity, gas, heat and water meters read over Modbus and M-Bus into one local database
- Per-tenant and per-zone attribution for service charges and lease negotiations
- History kept locally with no subscription — your consumption data is not a rented service
- Anomalies flagged: the compressor that never stops, the heating that runs all weekend
Load management
- Peak-load supervision stages non-critical loads before the building exceeds its supply capacity
- EV chargers managed as a group so ten cars share the connection intelligently
- Avoids the six-figure conversation with the DNO about a bigger supply
- Priorities you set: the server room never sheds, the towel rails always do
Tariff & generation aware
- Flexible loads scheduled against time-of-use tariffs rather than a fixed clock
- Solar PV and battery storage integrated, with self-consumption prioritised
- Hot water treated as a thermal battery — heated when energy is cheap or free
- Every decision logged, so you can see why a load ran when it did
Reporting & compliance
- Dashboards for the people running the building; exports for the people auditing it
- The numbers behind ESG statements, EPC improvement plans and Part L conversations
- Baseline first: the opening weeks of data show where the waste actually is
- Savings measured against that baseline, not against a brochure claim
Where The Energy Goes
In most buildings, the biggest load is the climate.
Metering shows what the heating, cooling and ventilation cost. Controlling them properly is where that number comes down — zoning, interlocks and demand-led ventilation on the same controller as the meters. The two pages are halves of one system.
Heating, cooling & ventilation controlQuestions
Energy management,answered honestly.
What is a building energy management system (BEMS)?
A BEMS is the part of building control focused on energy: metering what the building uses, attributing it to zones and tenants, managing peak loads, and scheduling flexible loads against tariffs and on-site generation. In our installations it is not a separate product — the same Loxone controller that runs the HVAC and lighting also reads the meters and manages the loads, which is precisely why the savings are achievable: the thing measuring the energy is the thing in control of it.
What does energy monitoring actually save?
Monitoring alone saves nothing — it shows you where the waste is, and in most buildings the first month of per-zone data is uncomfortable reading: heating running against cooling, whole floors conditioned out of hours, a single stuck valve costing more than the monitoring did. The savings come from acting on it, which is why we install metering and control together. We deliberately do not promise a percentage before seeing your baseline.
Can you meter tenants separately for billing?
Yes. Sub-meters per tenancy or per floor feed one local database, and consumption reports can be produced per tenant for service-charge reconciliation. For formal resale of energy you should take advice on the billing regulations that apply to your lease structure — what we provide is accurate, timestamped, per-tenant measurement, which is the part most buildings are missing.
Does this work with solar panels and batteries?
Yes — PV inverters and battery systems integrate over Modbus or their native interfaces, and the controller prioritises self-consumption: flexible loads like hot water and EV charging run when generation is high, the battery covers the evening peak, and the grid takes what is left. On a commercial roof the difference between exporting at a few pence and consuming on site is where the payback lives.
Is our energy data sent to a cloud service?
No. Metering history is logged and stored locally on the system in your building, and remote dashboards read from it when you want access from elsewhere. There is no subscription that expires and takes your history with it, and no third party holding your consumption data.
