Commercial Energy Audits for Buildings
What is a Commercial Energy Audit?
A commercial energy audit is a structured assessment of how a building performs in operation. By combining energy data analysis with a review of building services systems, controls and operational practices, an audit helps identify inefficiencies, understand why energy is being consumed and prioritise opportunities for improvement.
For building owners, landlords and asset managers, energy audits provide the evidence needed to reduce energy costs, improve operational performance and inform future investment decisions.
The audit provides building owners, landlords, occupiers and asset managers with a clear understanding of how their building operates in practice. The findings can support investment decisions, help prioritise improvement works and identify opportunities to reduce operating costs.
How Energy Audits Support EPC and MEES Planning
Many organisations commission an energy audit because they need to understand how a building is performing before committing to improvement works. An audit provides an evidence-based understanding of how energy is being used, where inefficiencies exist and which measures are likely to deliver the greatest benefit.
While an energy audit is different from a commercial EPC assessment, the findings can help inform EPC improvement strategies by identifying practical opportunities to improve building performance. This can be particularly valuable for landlords and asset managers assessing future Minimum Energy Efficiency Standards (MEES) risks across individual assets or wider portfolios.
By understanding both how a building operates and where energy is being consumed, owners can make more informed investment decisions and focus expenditure on measures that deliver meaningful operational, financial and environmental benefits.
Where required, KJ Tait can combine commercial energy auditing, EPC assessments, EPC improvement studies and building services engineering advice to help clients understand both current performance and potential future improvement pathways.
Frequently Asked Questions About Commercial Energy Audits
What is a commercial energy audit?
A commercial energy audit is a structured review of how a building uses energy. It examines plant, equipment, controls and operating patterns to identify where energy is being wasted and where practical improvements can be made.
Who should commission a commercial energy audit?
Commercial energy audits are commonly commissioned by landlords, occupiers, asset managers, facilities managers and organisations responsible for reducing operating costs, improving building performance or planning future compliance works.
What is the difference between a commercial EPC and an energy audit?
A commercial EPC assesses the theoretical energy efficiency of a building using a standard calculation methodology. An energy audit examines how a building is actually performing in operation, identifying inefficiencies, operational issues and opportunities for improvement. The two assessments provide different insights and are often most valuable when used together.
Should landlords commission an energy audit before EPC improvement works?
In many cases, yes. An energy audit provides a better understanding of how a building operates in practice, allowing landlords and asset managers to prioritise improvement measures that support both operational performance and wider EPC objectives.
Can an energy audit help improve an EPC rating?
An energy audit can help identify opportunities that may contribute to EPC improvement. Audit findings can be reviewed alongside EPC modelling to understand which measures are likely to have the greatest impact on building performance and compliance objectives.
Can an energy audit help prepare for MEES requirements?
Yes. While an energy audit is not a formal MEES assessment, it can help identify energy efficiency improvements that may support future EPC improvement strategies and reduce potential compliance risks associated with Minimum Energy Efficiency Standards (MEES).
How can a commercial energy audit reduce energy costs?
An energy audit identifies where energy is being used inefficiently. Recommendations may include operational changes, controls optimisation, maintenance improvements or capital investments that reduce energy consumption and unnecessary expenditure.
What information is needed for a commercial energy audit?
Useful information may include utility bills, half-hourly data, sub-metering data, building drawings, maintenance records, BMS information, occupancy information and previous EPC or energy reports where available.
What types of buildings can be audited?
Commercial energy audits can be undertaken for offices, industrial facilities, education buildings, healthcare facilities, retail premises, mixed-use developments and wider property portfolios.
What happens after the energy audit is completed?
The audit report provides a clear evidence base for decision-making. Clients can use the findings to improve operational performance, plan capital investment, support compliance activities and develop longer-term decarbonisation strategies.
