Asset Register

Technology & CAFM

A comprehensive, centralised inventory recording every maintainable plant item, mechanical asset, and electrical system within a property.

An asset register catalogues technical specifications, make, model, serial numbers, location, installation date, warranty status, and replacement asset value across an estate. In modern FM operations, assets are physically tagged with durable barcodes or QR codes synchronised directly with a Computer-Aided Facilities Management (CAFM) platform.

Operational Significance:

Without an accurate asset register, preventative maintenance schedules cannot be verified, statutory obligations are easily missed, and long-term capital expenditure (CapEx) forecasts remain inaccurate.

BMS (Building Management System)

Engineering & M&E

A computer-based control system installed in buildings that controls and monitors mechanical and electrical equipment.

A BMS (or Building Automation System) orchestrates ventilation, heating, cooling, lighting, power systems, fire alarms, and security devices. It allows facilities managers to monitor environmental comfort parameters in real time, automate energy setpoints, and receive instant diagnostic alerts on plant malfunctions.

Operational Significance:

Optimised BMS tuning significantly lowers commercial energy consumption, prevents unnecessary plant wear, and maintains tenant comfort covenants without manual plantroom intervention.

Emergency Lighting Testing

Compliance & Statutory

Statutory inspection and discharge testing ensuring backup illumination illuminates escape routes during a mains power failure.

Under BS 5266-1 and the Regulatory Reform (Fire Safety) Order 2005, emergency lighting systems require monthly functional "flick tests" using fish-keys to simulate power loss, plus an annual full-duration 3-hour discharge test to prove battery autonomy.

Operational Significance:

Essential for occupant life safety during fires and blackouts; failed emergency luminaires represent an immediate statutory non-compliance.

Related Terms:Fire Risk AssessmentStatutory MaintenanceLife Safety

F-Gas Regulations

Compliance & Statutory

UK statutory environmental legislation governing the containment, leak checking, and recovery of fluorinated greenhouse refrigerant gases.

Applies to commercial air conditioning, VRF/VRV systems, and chillers. Systems exceeding specific CO2 equivalent thresholds require mandatory periodic leak inspections (every 3 to 12 months), certified engineer handling (City & Guilds 2079 / REFCOM), and comprehensive digital F-Gas logbooks.

Operational Significance:

Non-compliance carries severe Environment Agency enforcement fines; undetected refrigerant leaks reduce cooling efficiency and increase electricity bills.
