Energy audits and baselines
Scope and deliver facility energy assessments, including AS/NZS 3598:2014 Type 2 audits where appropriate. Establish electricity, gas and other energy baselines, major end uses and operational constraints.
Impact Zero | Engineering, Energy & Sustainability
Energy Efficiency & Auditing
Improve energy performance through engineering analysis, operational optimisation and practical investment planning. Impact Zero supports commercial, industrial, healthcare and public-sector facilities, from identifying losses to verifying improvements.
Discuss your projectWho we support: Commercial and industrial facilities, healthcare, education, government and other asset-intensive operations.
Electricity, gas and demand analysis
Review bills, interval data, tariffs, maximum demand and seasonal load profiles. Distinguish avoidable energy use from network charges and operational requirements.
HVAC and central plant efficiency
Assess chillers, boilers, heat pumps, pumps, fans, ventilation and building management systems. Examine equipment performance, sequencing, setpoints and part-load operation.
Industrial and process efficiency
Review process heating and cooling, compressed air, motors, variable-speed drives, heat recovery and production schedules to identify feasible improvements.
Financial and carbon assessment
Compare capital costs, energy and demand savings, maintenance implications, emissions reductions and implementation risks using transparent assumptions and sensitivity analysis.
Measurement and verification
Define metering and performance indicators, review operating conditions and develop post-implementation measurement and verification plans.
Our engineering approach
- Define scope, operating constraints and data availability
- Develop an energy-use and demand baseline
- Inspect systems and test engineering opportunities
- Rank measures by cost, risk, practicality and carbon impact
- Support implementation and verify outcomes
Frequently asked questions
Do all projects require a formal energy audit?
No. A targeted plant review, data analysis or engineering feasibility assessment may be more suitable. A formal AS/NZS 3598 audit can be scoped when required.
Can you assess both electricity and gas?
Yes. Assessments can consider electricity, gas, energy demand, operating schedules and relevant tariffs, subject to available data.
Can the analysis support capital planning?
Yes. Feasible measures can be compared using estimated capital expenditure, operational savings, risks and implementation dependencies.
