Energy Audits
Energy Audits That Focus on What Matters Most
Most energy audits produce lengthy reports and extensive recommendation lists. Zerith takes a different approach — identifying where your organisation consumes the most energy and concentrating effort where it delivers the greatest impact.
Our Story Starts Before We Arrive
Every energy audit starts before we arrive.
Before we ask you to commit to an energy audit, Zerith commits time to understanding your business. Every project begins with a complimentary half-day desktop review before our initial consultation.
Most consultancies begin learning about your buildings during the first site visit. We begin before we've even met.
What we review
Utility consumption & billing trends
AMR / sub-metering data
Existing energy reports
Building portfolio info
Operational activities
Production processes
Existing BMS
Previous improvement projects
What that delivers
Better first conversations
Faster mobilisation
Early opportunity ID
Better targeted audits
More valuable recommendations
Confidence audit hits what matters
Not every building needs a full energy audit.
Many organisations assume every building and every system requires the same level of investigation. Sometimes that's appropriate. Often it is not.
When effort is spread evenly across every system, the greatest opportunities get the same attention as insignificant ones.
The Zerith Approach
Focus effort where it delivers the greatest value.
Using the pre-assessment, energy data review and discussions with your team, we identify the systems most likely to influence energy performance before the audit even begins.
Compressed Air
Cooling & Chilled Water
Steam Systems
Heating Systems
Air Handling Units
Refrigeration
Electrical Distribution
Motors & VSDs
BMS
Process Equipment
Consultant-Led Energy Audit
A fully managed assessment from planning and surveys through to reporting — ideal for limited internal resource or an independent technical review.
Energy Treasure Hunts
A collaborative, organisation-wide event — workshops, validated opportunities, quantified savings, and prioritised improvements that traditional audits can overlook.
Why Clients Choose Zerith
Success isn't measured in pages.
We do not believe success is measured by the number of pages in an audit report. Success is measured by reduced energy costs, improved operational performance, and practical recommendations that actually get implemented.
Accompanied & Guided Audit
Your team works alongside our consultants — mentoring, technical guidance and practical knowledge transfer while jointly undertaking the audit.
Energy Kaizen
Continuous improvement focused on a specific process — compressed air, HVAC, steam, refrigeration or production lines — owned by your operational teams.

Frequently Asked Questions
What clients ask before booking an audit
What does the audit actually cover?
Scope is shaped by your free pre-assessment — we focus engineering time on the systems most likely to be driving your energy costs, rather than treating every system equally.
How long does an audit take?
Duration depends on site complexity and which delivery model you choose — your pre-assessment consultation will confirm a realistic timeline for your specific estate.
What information do you need from us beforehand?
Typically utility bills, any sub-metering or AMR data, existing energy reports, and basic information on your building portfolio and operations — all gathered during the complimentary desktop review.
Do you help us implement the recommendations, or just report them?
Every report includes a practical implementation roadmap, and our delivery models — including Accompanied Audits and Energy Kaizen — are built specifically to support hands-on implementation, not just a document.
Is there follow-up support after the audit?
Yes — the optional ZECO AI integration lets you track delivery and monitor progress on recommendations after the audit is complete.
How is return on investment calculated?
Your financial appraisal includes payback estimates for prioritised opportunities, so investment decisions are backed by numbers, not just engineering judgement.
