Service
Building Energy Auditing
Structured analysis of where energy is consumed in a building and where it can be saved.
Overview
What this service involves
Building energy auditing is the systematic study of a building’s energy use, from the utility-level totals down to the individual systems and components responsible for consumption.
A properly conducted audit combines metered data, on-site investigation, and engineering analysis to identify where energy is wasted, why, and what it would cost to remediate. The resulting opportunities are prioritised on payback, technical effort, and operational disruption — so the owner can make capital decisions on evidence rather than instinct.
Audits are commonly scoped at three levels of depth, broadly aligned with the ASHRAE classification: a walkthrough assessment for quick wins, a detailed audit for prioritised investment-grade analysis, and an investment-grade audit when capital is committed and certainty matters.
Scope
Scope of work
- Utility bill analysis and benchmarking against comparable assets
- On-site walk-through and equipment inventory
- Metered data collection (where present) and short-term sub-metering when required
- BMS and controls review — operating sequences, set points, schedules
- HVAC, lighting, and plug-load opportunity identification
- Energy and demand modelling for shortlisted measures
- Economic analysis: payback, NPV, and lifecycle cost for each measure
- Implementation roadmap and measurement-and-verification planning
Process
How we deliver this
Baseline and benchmarking
Analyse utility bills, identify major energy end-uses, and benchmark consumption against comparable assets.
Site investigation
Walk the building, inventory equipment, review BMS sequences and set points, and capture short-term sub-metered data where useful.
Opportunity identification
Engineering analysis of HVAC, lighting, plug loads, and controls to identify and quantify savings measures grounded in evidence.
Economic ranking
Apply payback, NPV, and lifecycle cost to each measure to produce a prioritised opportunity register the owner can act on.
Implementation roadmap
Propose a phased implementation plan and an M&V approach to verify savings post-implementation.
Benefits
Why owners engage us for this
- A defensible, prioritised list of savings opportunities — not a generic checklist
- Reduction of utility cost and exposure to tariff changes
- Improved occupant comfort as a side-effect of correctly tuned systems
- Evidence supporting sustainability reporting and certification submissions
Deliverables
What you receive
- Energy audit report with executive summary and full technical findings
- Prioritised opportunity register with payback and capital cost
- Energy model files (where modelling was performed)
- Measurement-and-verification plan for measures the owner chooses to implement
