# NABERS as a Service > NABERS as a Service: we get your building rated under NABERSNZ Energy and keep it rated, with the pre-assessment included. Source: https://betterbuildings.co.nz/nabersnz Last updated: 2026-10-08 ## A rating proves your building performs. Getting and keeping it shouldn't be hard. With NABERS as a Service, we take the lead on your NABERSNZ Energy rating, from getting rated to staying rated, year after year. Whether it's an office, warehouse, cold store, retail store or shopping centre, we manage the process for you. [Talk to us about your rating](https://betterbuildings.co.nz/contact). [See your projected rating](https://betterbuildings.co.nz/coming-soon) ## One rating pays back four ways. A NABERSNZ Energy rating is more than a certificate. It could help you access better finance, identify opportunities to reduce energy costs, strengthen the long-term position of your asset, and give your bank, board and tenants credible evidence of how your building performs. ### Lending **Better performance can mean better finance.** Eligible rated buildings and buildings on an approved pathway to an eligible rating may be able to access better finance terms. ### Lower energy costs **Measure it. Manage it. Improve it.** A rating starts with understanding how your building actually uses energy. Better data helps reveal where energy is being wasted and where improvements can pay back. ### A stronger asset **Performance increasingly matters to tenants, valuers and buyers.** Efficient, well-performing buildings can be more attractive to occupiers and better positioned as expectations around building performance rise. ### Proof that holds up **Independent evidence, not projections.** A NABERSNZ Energy rating gives your bank, board and tenants independently verified evidence of actual building performance. ## Better-rated buildings may be able to borrow on better terms. ASB Bank supports lending for better-performing buildings, and eligible owners may be able to access ASB Bank sustainable finance options, benefitting from discounted interest rates. Importantly, you may not have to wait until the final rating is achieved. Agree an eligible rating pathway with ASB Bank, and it can support you once that pathway is approved. A rating pathway maps where your building is today, the rating you're targeting and the steps required to get there, beginning with a pre-assessment. - **Offices.** The qualifying threshold is a 4.5 star NABERSNZ Energy rating. - **Warehouses, cool and cold stores, shopping centres and retail stores.** The qualifying threshold is a 4 star NABERSNZ Energy rating. There is also growing evidence that the market values better-performing buildings. (CBRE, 2025; JLL, 2024) **See what ASB Bank offers better-performing buildings.** ASB Bank's sustainable finance options are set out on its own site. ASB Bank decides who is eligible, and on what terms. [Explore ASB Bank sustainable finance](https://www.asb.co.nz/business-banking/sustainable-finance.html). Final lending decisions sit with ASB Bank. ## Start from where your building is today. ### Not rated yet **Find out where you'd land.** See a projected rating, what it would take to reach your target, and what it's worth to your building. ### Rated, and ready to get more from it **Your rating could be working harder.** Connect it to ASB Bank sustainable finance and see what the work you've already done could be worth. ### Rated, and want to keep it that way **A rating you can't hold is a rating you can't rely on.** Hand it over.

Everything from the NABERSNZ Energy pre-assessment to your yearly re-rating: getting your building ready to be rated, your baseline, your plan, a report every quarter, organising your certification, and live tracking with early warnings. A Better Buildings Check, if your building needs one, is extra, and so are the upgrades themselves. ### 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. ### How long do I sign up for? The minimum term is 12 months, the life of one rating. ### What do I need to do? Give us access to your bills, meter data and drawings, approve the plan, and decide on each upgrade. We do the rest, and we'll tell you whenever we need something from you. ### Can you take over a rating we already have? Yes. If your building already holds a NABERSNZ Energy rating, we'll manage it from here: we track it, keep the evidence ready and organise every re-rating. ### Which rating does my building need? NABERSNZ Energy for offices, warehouses, cold stores, retail and shopping centres, and that's the rating we get for you. Aged care is rated under Green Star Performance, a separate scheme. Add your building and we'll confirm which applies. ### What is a NABERSNZ Energy rating? An independent star rating of how efficiently your building actually uses energy, measured over a full year and compared with similar buildings across New Zealand. It isn't a prediction from the design drawings. It can cover the whole building, just the core building services the owner controls, or a single tenancy, and it lasts 12 months from the day it's certified. ### What rating do we need for ASB Bank sustainable finance? For offices, the threshold is a 4.5 star NABERSNZ Energy rating. For warehouses, cool and cold stores, shopping centres and retail stores, it is a 4 star NABERSNZ Energy rating. Your projected rating shows how far you are from it. Final lending decisions sit with ASB Bank. ### What if we commit to a target and don't reach it? Live tracking shows you against the target throughout, so you'll know early and have time to act. If the target is missed, a lending benefit that depends on it may be at risk. That's a conversation to have with your business banker at ASB Bank. ### How long does the whole thing take? A projected rating takes minutes. A certified rating needs 12 months of verified data after metering is in place. Lending benefits can start well before that. ### Do I need to bank with ASB Bank? No. Anyone can get rated with us. ASB Bank sustainable finance is for eligible ASB Bank customers. ## Let's get your building rated, and keep it there. Tell us about your building, and we'll show you where it would land, what it would take, and what NABERS as a Service would do for it, even if the answer is that now isn't the right time.
