Share with your CFO
Frame measurement and conservation as operating cost and capital discipline, not sustainability theatre.
Intended reader: Finance / CFO
Suggested talking points
- Wasted energy is recurring opex that rarely appears as a named line item.
- Indicative screening is cheap; temporary plant measurement establishes real kW/RT performance.
- Target cooling plant performance of 0.58 kW/RT at 8.5°C is a benchmark to pursue, not a guaranteed after figure.
- Spend is staged: free calculator → low-cost assessments → measured studies from SGD 4,950 subject to site suitability.
- Verified avoided energy use (later) can support assurance; estimates alone should not.
The ask
Approve a portfolio scan or a single chiller performance study as a pilot with a clear evidence deliverable.

Life-cycle view
Avoid icebergs: procurement is not the whole cost
CapEx is visible. Energy, maintenance, and performance drift sit below the waterline for decades.

What the bid shows
Life-cycle costs
Energy, maintenance, downtime, carbon, and re-procurement
Conceptual. Measurement makes the submerged cost visible before you commit capital.

What a plant efficiency step-change can look like
Example model inputs and outputs for a large cooling plant retrofit. Not an offer. Not a guarantee. Tariff, load, and CAPEX vary by site.

Illustrative structure
Drawn from structured plant-performance financing models used in industry presentations. Negawatts.io will size every project from site data. DIFY field work is typically considered when indicative annual conservation value is SGD 50,000 or more.
