Testimonials

What they say
OUR CLIENTS

  • Jesus is an absolute ROCK STAR when it comes to passive house. I first met him at the international Passivhaus conference and he was keen to help me achieve my ambitions. Although we didn't work together initially, when we finally did, the knowledge he brought to the table has catapulted PureHaus forward. Zero Energy is a fantastic team of talented engineers, architects and trainers 100% focused on passive house and sustainable construction. I can recommend working with the team whether you need a retrofit assessment, buildings design, engineering, MVHR design, PHPP, training to certification. Further more, I can honestly say that I have not worked with a company more integrity, drive to educate and desire to change the construction industry for the better than Zero Energy, and this is all down to Jesus and his commitment to builds better world. Jesus and his team can provide customers with a short cut to zero.
