The customer problem

Building improvement is still too hard to get done.

Bills, BMS alarms, audits, finance, suppliers, and rating evidence all live in different places. That is why obvious improvements still stall.

Tether turns scattered evidence into one path: fix, fund, deliver, and prove.

A ranked plan for the next move What should be fixed first?

Tether ranks each move by saving, cost to deliver, readiness, funding value, and proof path.

From advice to delivery

One path from advice to completed outcomes.

Advice only matters when the work is scoped, delivered, and proven. Tether keeps every handoff tied to one baseline.

The shape of a saving

What a verified saving looks like.

This is an anonymised 24-hour load curve from a commercial office project. The dashed line shows the expected baseline. The solid line shows measured consumption after the improvement work was delivered.

A saving is only verified when you can show the baseline, the measured result, and the method used to compare them. That is the evidence your board, lender, assessor, auditor, or internal team can trust.

Five outcomes

Five ways to read one building.

Start with the outcome the customer needs. Organise the evidence once.

Cost. Value. Rating. Proof. Risk.

Save Money

Save money.

Find waste, reduce operating cost, and prove the saving.

Pressure

Operating cost leaks through schedules, controls, maintenance, water, or metering gaps.

Path

Separate normal load from avoidable waste, rank fixes, and measure the saving after delivery.

The Performance Review

A full health check and Performance Plan for your building.

You know your building should be doing more. Saving money, making money, certifying, funding the next move, hitting a reporting deadline. You don't know what's possible, what to do first, who to use, or how to pay for it.

The Performance Review answers all of that in one detailed report. We agree the outcomes you need. We assess what the building can deliver. We return a plan with every option scoped, costed, ranked, and matched to funding.

Three to six weeks for a single building.

Align

Agree what success looks like.

We meet to understand the outcomes you need from your building. Save money, make money, certify, fund, report, comply. Whatever the building has to deliver, the plan is built around it from step one.

What the market is signalling

Performance now has to prove itself.

One green loan application now asks for the rating, the energy baseline, and the operating cost in the same evidence pack, and the lender checks each number against what the meters recorded.

Mackersy Property took that pack to its lender.

Evidence that can leave the room

One baseline for the board, bank, assessor, supplier, and delivery team.

  1. 01 CAPITAL

    The money needs a reason.

    Owners and lenders won't fund work without a credible baseline, a costed pathway, and proof the savings will hold. Hope is not a business case.

    FUNDING CASE
  2. 02 COMPLIANCE

    The clock is real.

    Reporting deadlines and obligations are landing on the same building. Your team needs owners, dates, actions, and a record that survives an audit.

    ACTION RECORD
  3. 03 PROOF

    Claims need a method.

    Boards, auditors, assessors, and tenants are no longer accepting modelled numbers. Every performance claim needs a baseline behind it.

    BASELINE METHOD
  4. 04 COST

    Energy waste sits in the after-hours plant.

    At one regional shopping centre, 38% of the energy was used outside trading hours, on carpark lighting and HVAC schedules nobody had revisited.

    RANKED SAVING
CAPITAL SIGNAL

We needed a NABERSNZ rating to qualify for green finance and to anchor a tender process. Without a credible baseline, we couldn't get either.
