Glad you asked. Here’s how Powerhaus makes it simple.
how it works
We help you design high-performance, sustainable homes using a two-stage energy rating process
stage 1: During development of your Design

FIRST ENERGY RATING & ENERGY Efficiency DESIgn APP
We use your plans to do an initial NatHERS star rating, and allow you to optimise the design using the Powerhaus app.
We provide an energy rating at the design phase, so that you know how your design will perform. You can make changes to improve the performance and comfort, and avoid expensive revisions or building upgrades later in the process.
Use the Powerhaus energy efficiency design app to:
stage 2: During Final building approvals

Second energy rating & certificates
We finalise your paperwork, with the final thermal modelling and NatHERS star rating.
With your insights from design stage, the project moves through final NatHERS compliance (or Performance Solution) quickly and easily.
