What our users say

For years, the true potential of the NatHERS software as a design tool was only accessible if paired with a trained thermal performance assessor. This often made the design process slower, more expensive, and limited the ability of designers to learn directly from the software.

The Powerhaus dashboard is a game-changer. Its superbly designed interface allows designers to instantly test the impact of various critical parameters, giving them a clear understanding of the most effective levers for any particular design.

At The Mill, we have long been looking for a tool that will allow us to learn and grow as designers, whilst making real time decisions that impact our projects. This tool is exactly that… it is infinitely valuable for us to have quick access to the impact adjustments to the built form will have on the thermal performance. We can’t wait to use it for all of our projects!
