TESTIMONIALS

Helping our partners succeed

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. Andrew has a real passion for his work and is always willing to find desirable outcomes.

Powerhaus’ ability to assess each of our projects on a whole-of-project level for improving EER ratings is indispensable.
