After several years of working together, I now consider Andrew to be an integral part of the "team" approach we take to each of our projects.

Energy assessments of buildings require a holistic approach, it is not just a case of applying software to numbers and dimensions of rooms etc Andrew has a real passion for his work and is always willing to find desirable outcomes.

The Powerhaus dashboard is a powerful and easy-to-use tool which lets us behind the curtain of star ratings. For the first time we can tune and test various inputs ourselves to see how best to achieve a high performing home.
