Upgrade decisions backed by numbers.
For owners, asset managers and investment committees, a mechanical upgrade is a capital decision. We turn energy data, plant condition and upgrade options into a clear business case — capital cost, running cost, payback and risk — that stakeholders can test and approve.
What the analysis covers
From the bills to the business case.
Baseline
Utility bills, interval meter data and BMS trends used to establish how the building uses energy now, and how much of it goes to heating, cooling and ventilation.
Options
Like-for-like replacement compared with higher-efficiency alternatives such as chiller replacement, heat pump conversion, variable speed drives, controls optimisation or ventilation heat recovery.
Financials
Capital cost, annual energy and maintenance savings, simple payback and lifecycle cost over the life of the plant, with every assumption stated so it can be checked.
Risk
Refrigerant phase-down, end-of-life parts support, tenant comfort and compliance exposure set out alongside the dollars, so the decision is not made on payback alone.
Who it’s for
Written for the people who sign off.
The output is a short, plain-English report with the numbers behind it — suitable for a board paper, an investment committee or a capital works budget.

How it runs
From data to verified savings.
01
Collect
Bills, meter data, BMS trends, maintenance records and a site inspection of the plant.
02
Model
Baseline established and each upgrade option assessed on energy, cost and risk.
03
Report
A business case with options ranked, assumptions listed and a recommended path.
04
Verify
After installation, measured performance is compared with the forecast.
Good to know
Forecasts, not promises.
Savings estimates are forecasts based on stated assumptions and the data available. They are not guaranteed, which is why we recommend measuring performance after the upgrade.
- Every assumption listed, so it can be challenged
- Ranges shown where uncertainty is high
- Formal NABERS ratings are carried out by accredited NABERS assessors
- Section J compliance for new work is assessed on the applicable NCC edition and pathway
What information do you need to start?
Twelve months of electricity and gas bills is a good start. Interval meter data, BMS trend logs, maintenance records and existing plant schedules let us go further.
Are the savings guaranteed?
No. Estimates are forecasts. We state every assumption, show a range where uncertainty is high and recommend measurement after installation so actual savings can be checked against the forecast.
Can this support a NABERS improvement?
It can identify the HVAC measures most likely to improve energy performance. A formal NABERS rating must be carried out by an accredited NABERS assessor.
