Measurement · Conservation · Evidence
Find your Negawatts.
Measure real plant performance, cut unnecessary load, and verify conservation under operating conditions.
Built for portfolios and central plant-heavy assets. Featured locations: Sydney and Singapore. Representative offices: Perth, Brisbane, and Townsville.
How much energy is your building wasting?
For a desktop performance estimate, attach three months of operators log sheets. Form-only results stay rough and indicative, not verified conservation.

How you work with us
To enable your journey, no matter how big or small
Every organisation can start. DIY tools and DIWY specialist support carry smaller opportunities. DIFY field delivery is for when indicative annual conservation value reaches SGD 50,000 or more, so the path always matches the size of the prize.
Path sizing · DIFY value quantum
≥ SGD 50,000/ year → field delivery
Below SGD 50,000: DIY and DIWY keep you moving. At or above: DIFY measurement is usually the right next step. Start free either way.
Self-serve
You run the tools.
Screening, early scoping, and smaller opportunities.
Start here for any size of site: free tools and low-cost certificates so every journey can begin.
With specialists
You work with our team.
Assessments, hunts, baselines, and MRV planning with professional review.
Specialist support for smaller opportunities, and the bridge that prepares larger ones for field measurement.
We deliver
Negawatts.io and, where appropriate, approved partners.
Field measurement, plant studies, and implementation. Delivery may be by Negawatts directly or via the partner network, depending on location, geography, scale, procurement, and capability. Own solutions such as vChill, vGrid, and vPool may apply.
When indicative annual conservation value reaches SGD 50,000 or more, full field delivery is the right path. Still sized to your plant, not a one-size study.
The SGD 50,000 figure is indicative annual conservation value (avoided energy cost at your tariff): a sizing guide so field work fits the opportunity. It does not block smaller sites: DIY and DIWY are built for them. A free estimate shows where you sit on the path. Full product catalogue →

Energy not used is energy that still has to be measured.
Portfolios and central plant-heavy assets. Find the waste, measure the plant, verify the conservation.
Sequence
Find → Measure → Optimise → Verify → Conserve
Each stage increases evidentiary certainty. Start with a free calculator; progress to temporary instrumentation when the plant justifies it. Operations then run as a closed loop, not a straight line that ends at the report.
Closed loops
Start with audit. Finish with audit. Keep learning.
Conservation is not a one-off report. Continuous commissioning, feedback, and learning cycles return to measurement so performance does not drift.
Continuous commissioning: audit opens and closes the loop so the plant is re-checked after every improvement.
Learning cycle: each intervention feeds the next observation, not a static baseline forever.
Evidence cycle: estimate, measure, verify, prove, then improve and re-enter with higher certainty.
Plant performance

Typical plant intensity includes design, commissioning, controls, and maintenance. Optimised operation cuts the whole stack.
Where the kW/RT goes
Typical plant intensity includes design, commissioning gaps, controls, and maintenance. Optimised operation cuts the stack, not just one component.

Signature measurement
Don't estimate performance. Measure it.
We temporarily instrument cooling plant and establish the actual performance curve under real operating conditions.
