- AHUAir Handling Unit
- The unit that conditions and moves air around a building — heating, cooling, filtering and circulating it.
- Baseline
- A model of what your building’s energy use ‘should’ be, adjusted for weather and occupancy. Savings are measured against it, so results aren’t just down to a mild month.
- BACnet / Modbus
- The common ‘languages’ building equipment uses to talk to each other. Enerzyz connects over these, which is why it works with most existing systems.
- BMSBuilding Management System
- The control system that runs a building’s plant — HVAC, chillers, pumps and more. It monitors and schedules equipment. Enerzyz adds continuous optimisation on top of it.
- CAPEX / OPEX
- Capital expenditure (buying equipment up front) versus operating expenditure (ongoing running cost). Enerzyz typically needs no CAPEX (subject to a property assessment) — nothing to buy or rip out.
- Chiller
- The machine that produces chilled water to cool a building. Usually the single biggest energy user, which is why it’s a primary focus for optimisation.
- COPCoefficient of Performance
- How efficiently a chiller or heat pump turns electricity into cooling or heating. A higher COP means less energy for the same result.
- Edge device
- A small, secure on-site appliance that reads equipment data and sends it out to Enerzyz. It connects outbound only — it opens no inbound ports on your network.
- ESCOEnergy Service Company
- A provider that delivers energy savings, sometimes paid from a share of those savings. Where applicable, Enerzyz engagements can use a similar shared-savings model.
- FCUFan Coil Unit
- A smaller in-room unit that heats or cools the air in a specific space, such as a guest room or office.
- HVACHeating, Ventilation and Air Conditioning
- All the systems that keep a building at the right temperature and air quality. In many buildings it’s the majority of the energy bill.
- IPMVP
- The International Performance Measurement and Verification Protocol — the recognised standard for proving energy savings are real. Enerzyz verifies savings against it.
- kWhkilowatt-hour
- The standard unit of electricity use. Your bill is essentially a count of kWh, so cutting kWh cuts cost.
- OTOperational Technology
- The equipment and control systems that run a physical building — as opposed to IT (email, guest data). Enerzyz works in the OT layer and doesn’t touch personal data.
- PUEPower Usage Effectiveness
- A data-centre efficiency measure: total energy divided by the energy that actually reaches the IT equipment. Lower is better; ‘PUE drift’ signals waste creeping in.
- Shared-savings model
- A commercial arrangement where you pay from a share of the verified savings delivered — so cost is tied to results.
- Telemetry
- The operational readings equipment produces — temperatures, power draw, run-times. Enerzyz reads this telemetry; it needs no guest or personal data.
- tCO₂etonnes of CO₂ equivalent
- A standard way to express carbon emissions. Cutting energy use cuts tCO₂e, which feeds ESG and sustainability reporting.
- VAVVariable Air Volume
- A system that varies how much conditioned air is delivered to each zone, rather than running flat out — a common efficiency lever.
- VRF / VRVVariable Refrigerant Flow / Volume
- A widely used air-conditioning system (Daikin, Mitsubishi and others) that varies refrigerant flow to match demand. Enerzyz supports it where a compatible controller is present.
