Comprehensive Energy Audit provides Green Zone Surveys’ client with deeper understanding of usage and potential savings thanks to in-house developed software, GreenAudit.
ETL Fluid Experts Ltd recently engaged Green Zone Surveys to undertake a detailed Commercial Energy Audit in support of their solar expansion plans and ongoing efforts to reduce carbon emissions. The audit was delivered using Green Zone Surveys’ in-house GreenAudit software, providing significantly deeper insight into energy usage. This case study outlines the audit findings, demonstrates how GreenAudit underpinned the depth and quality of the insights and highlights how these outcomes are helping to support the client’s net zero ambitions.
The Green Zone Approach
Through the expertise of our in-house Technical Manager, Green Zone Surveys carried out a comprehensive on-site energy audit, aligned with net zero best practice. The assessment included:
-
Review of historical energy consumption data.
-
Assessment of building fabric, lighting, heating and ventilation.
-
Evaluation of existing site and equipment efficiency.
-
Identification of operational improvement opportunities.
Audit Outcomes
The Energy Audit identified ten clear energy efficiency recommendations. Summary of outcomes included:
-
Total annual energy savings: 60,000 kWh
-
Annual carbon reduction: 10.5 tonnes
-
Annual financial savings (based on our recommendations): £19,500
The recommendations provide our client with a realistic and achievable roadmap, while directly supporting their wider objectives for future energy investment plans and long-term sustainability.
Our GreenAudit Software
GreenAudit is Green Zone Surveys’ in-house energy audit software, designed to deliver fully customised audit reports with clear, actionable insights.
The platform provides a detailed breakdown of a building’s energy consumption by type, use, activity and equipment, alongside an energy health check that benchmarks performance against similar buildings. GreenAudit generates a clear action plan outlining practical energy-saving measures, how they reduce consumption and how to implement them.
By automating data collection and standardising analysis, GreenAudit enables fast report turnaround times while accurately identifying cost-saving and carbon-reduction opportunities. This allows organisations to make informed decisions that improve efficiency and support progress towards Net Zero.
Shared Feedback
Iain Kilner, IT & Special Projects Manager at ETL Fluid Experts Ltd, said: “We are very pleased with the service we received from Green Zone Surveys. We instructed Green Zone Surveys for the audit as part of our business plan for solar expansion, and they offered the most realistic costs and timescale. The audit did highlight areas that we need to improve, but we were also aware of them from previous exercises. Ben, who came to the site, was great and very thorough and we would recommend Green Zone Surveys for a full energy audit.”
Ben Palmer, Technical Manager at Green Zone Surveys who carried out the audit, said: “The energy audit identified several opportunities to reduce overall energy consumption, improve system efficiency and lower operating costs through targeted upgrades and improved operational practices. This will support ETL Fluid Experts Ltd in their net zero ambitions for the future.”
Conclusion
Green Zone Surveys was proud to support ETL Fluid Experts Ltd through a Commercial Energy Audit, giving them a robust, evidence-based assessment of their energy performance. The audit demonstrated that meaningful reductions in energy use and carbon emissions are achievable with investment, complementing our client’s existing plans to increase on-site solar capacity.
