Refrigeration tuning and M&V wrapped around it.
From data to proof, held end-to-end.
Building programmes fail in the gaps between steps: data that never becomes a plan, a plan that never becomes a project, a project that never becomes proof.
Six steps, one owner, nothing dropped between them.
Everything reads off one operating record.
Bills, meter data, BMS history, and site facts go into one record from the first read. Every later claim points back to it.
Read it for a baseline, a rating, a report, or a verified result.
The right partner for every step.
Tether holds the record, then connects each building to the lenders, installers, assessors, and channels that take it forward.

Where the record shows up in buildings.
Two published engagements: a verified rating uplift with the saving attached, and green-loan evidence built before the project broke ground.
Auckland CBD A-grade office
An A-grade tower lifted a full star on its NABERSNZ rating without major capex. BMS tuning, after-hours profile changes, and tenant comfort feedback did most of the work.

Mackersy Property - Tristram Precinct
A Hamilton precinct started from a 2.0-star NABERSNZ base. An Opportunity Scan turned existing BMS data into a costed pathway: a projected 37% energy reduction and about $92,000 a year in savings, no major capex, and finance-ready documentation to support a green loan application.

The data exists. The pathway usually does not.
