The Better Buildings "Your Buildings" view: each building with its photo, type, stage, estimated star rating and the next step to take.Watch the video

Energy costs are rising. Tenants want more. Time is short.

Your building needs to be more energy resilient. Energy keeps costing more, and tenants expect more from the space they lease. But getting there is hard work: bills, quotes, advisers and paperwork, on top of everything else. So much admin, not enough time, and no clear idea what to change or how to make it happen.

We take on the admin. You get your time back.

Better Buildings helps you understand where your building stands, uncover what could make it better, and turn those opportunities into action.

Every answer, in one place.

Each stage picks up where the last one ended: no starting again, and no chasing between advisers, suppliers and the bank.

A building owner and a Better Buildings specialist, who holds an iPad for them both to see, stand at the start of a winding path. It passes the five stages in turn: Discover, a floor plan under a magnifying glass; Assess, a clipboard with a tick; Fund, a small bank with a leaf on it and a seedling beside it, for sustainable finance and saving; Deliver, a heat pump; and Monitor, a gauge. It ends at an office building, with a star rating plaque beside it, that waits dark until the path reaches its door; then it lights up, solar panels appear on its roof and an EV charger by its door, and the two people turn to it, delighted.

  1. Discover

    See what your building could do better.

    Give us your building's address, and within minutes see every opportunity worth pursuing, ranked by impact, each with an estimated saving, a payback range and a plain explanation. No site visit, no paperwork, no expertise needed.

  2. Assess

    Choose the level of certainty you need.

    Request free quotes from suppliers, book an on-site assessment, or both. Everything comes back into your plan in Better Buildings, and every verified figure is marked. What once was a plan, is now a business case.

  3. Fund

    Turn your plan into action.

    Whether you use your own capital, finance or a combination of both, Better Buildings helps you understand your options. Eligible projects may also access ASB Bank sustainable finance.

    And with the evidence behind your project brought together, you'll have a clearer case to take to the people who need to approve or fund it.

  4. Deliver

    Turn your decision into a better building.

    Move from plan to implementation with a clear view of progress. Follow each improvement from quote through to installation, and see your building's potential start to become reality.

  5. Monitor

    Better performance should be proven.

    Real-time monitoring shows how your building performs over time, helping you track the impact of improvements and stay on top of energy performance. See what's working, spot changes early and build the evidence to keep making better decisions.

  • NABERSNZ Energy
  • Green Star Performance

Independent certification such as NABERSNZ Energy gives ASB Bank greater confidence in a building's quality, efficiency and future resilience. Better-performing buildings can be more attractive to tenants, less exposed to rising energy costs and future regulation, and better positioned to retain their value over time.

And it shows: the best-rated offices sold for up to 9.8% more than unrated ones. (JLL, 2024)

What owners ask us most.

Do I need to be an energy expert?

No. We turn the technical detail into plain language and dollars. You make the decisions. We do the translating.

What does it cost?

The platform is free to use. The NABERSNZ Energy pre-assessment, the Better Buildings Check and NABERS as a Service each have a fee, quoted for your building, and you'll see the price before you commit.

What happens after I add my building?

You'll see an initial view of how it performs and which opportunities suit it.

What if the numbers don't stack up?

Then you'll know early, before you pay for an assessment or spend money on the work. We'll show you what would need to change for it to work.

What does "verified" mean?

Estimates show as a range until your assessor confirms them on site or a supplier quotes. Every verified figure is marked, so you always know which is which.

The first step takes minutes. That's all.

No cost, no commitment, no energy expertise needed. We'll show you what's possible, even if the honest answer is that now isn't the right time.
