AirIntelligent Energy & Plant Automation
We bridge the gap between heavy mechanical engineering and modern software logic. From designing control panels for 330kW boiler arrays to programming the graphical user interfaces (GUIs) that manage them, we deliver complete turnkey BEMS infrastructure.
Heavy Plant Integration
Full BEMS control for mechanical overhauls — inverter pumps, pressurisation units, commercial chillers.
Custom Software & GUI Design
We don't just install hardware — custom Tridium, Siemens and Trend software with intuitive operator dashboards.
Seasonal Commissioning
Continuous optimisation and seasonal logic tweaks for peak HVAC efficiency year-round.
You can’t manage energy you don’t measure.
Plant control cuts the waste; metering proves the saving and splits the bill. We design, install and maintain electrical metering and sub-metering — from a single incomer to fully sub-metered multi-tenant estates — and keep the data flowing back to where decisions get made.
Metering & Sub-Metering Installation
Direct-connected and CT-connected electrical metering across electricity, gas, water and heat — MID-approved meters where billing accuracy matters.
Meter Panel Design & Build
Metering panels designed, built, installed and commissioned by the same discipline that engineers our control panels — one contractor, one standard.
Metering Communications
Modbus, M-Bus and wireless LoRaWAN brought back to a single head end — plus fault-finding on existing metering networks that stopped reporting years ago.
aM&T & Tenant Billing Data
Automatic monitoring & targeting, landlord sub-metering and billing-grade consumption data for managing agents — every tenant pays for what they use.
