An energy audit is most useful when it answers a defined decision: which operating issues should be investigated, which projects need a business case, or what evidence is missing before investment. Preparing the right information helps the engineer spend site time on those questions. Use this checklist to brief an assessment of a building, industrial site or portfolio in any UAE emirate.
1. Define the decision and the site boundary
Write a short brief describing the problem, the assets included, the decision date and the people who will use the findings. Distinguish an initial opportunity assessment from an investment-grade investigation with detailed measurement and costing. Agree the required depth with the assessor rather than assuming every audit has the same scope.
List owned and leased areas, shared plant and tenant responsibilities. For a site supplied by district cooling, include both cooling and electricity data; otherwise the baseline may omit a material part of the energy picture.
2. Assemble records that explain consumption
Aim to provide at least one complete annual cycle of bills and meter readings, with more history where it is available and relevant. This is a preparation recommendation, not a universal legal requirement. Include actual units, billing periods and tariff information, not only the amount paid.
- Electricity, cooling, fuel and water records relevant to the agreed scope.
- Interval meter data and BMS trend exports, including units and timestamps.
- Floor areas, opening hours, occupancy and significant changes in use.
- For industry: shifts, production volumes, product mix and planned shutdowns.
- Equipment lists, drawings, maintenance history and previous energy studies.
3. Mark missing data rather than hiding it
Keep estimated readings separate from measured ones. Flag meter replacements, gaps, implausible values and changes in account boundaries. A useful data pack includes a short explanation of what cannot yet be reconciled.
If the available data cannot answer an important question, ask whether temporary instrumentation or a metering plan should precede the detailed assessment. More data is valuable only when it supports a decision.
4. Prepare access and the right people
Arrange the site induction, permits, escorted access and availability of the operating team. Identify who can export BMS records and who is authorised to approve testing. Share critical-service constraints and ongoing complaints before the visit. Any operational change should follow site procedures and be agreed with the responsible operator.
5. Agree what a usable report looks like
Request an energy baseline, a register of opportunities, transparent assumptions and a next action for each priority. The depth of engineering, costing and verification should match the brief. A screening estimate should be labelled as such, with the additional work needed before procurement.
Ask how interactions between measures will be treated. Replacing equipment and improving its operating hours cannot always be credited as two independent savings. Include a verification approach early, and assign someone to progress the findings after the report. If a continuing management process is required, ISO 50001 provides a framework for systematic energy management; an audit alone is not certification.
