Director / CEO

Hi, my name is Robert Whitehouse, Director of both Energy Efficient Homes and Whitehouse Builders. I have been building in New Zealand for 20 years and have gained my LBP, Master Builder and Passive House Trades Certification.

I have a passion for healthy living and I believe health starts with your home. Learning Passive House techniques has shown me the huge deficiencies in our current Standard Building Code and I want to share this knowledge.

It is a personal mission of mine to help provide New Zealanders with warm, healthy, energy efficient homes that perform to a high standard without huge associated costs.

Hi, I’m Tania Dempsey, Project Manager for Energy Efficient Homes. I have been with the company for the past 7 years and during that time have gained my ATTMA Blower Door Tester Registration. My position involves overseeing the day to day building of your home while liaising with contractors and clients alike. If you have any questions, i’m the one to ask!

When it comes to Energy Efficient Homes, I believe that everyone should be able to live in a warm and healthy home. I would like to see Energy Efficient Homes as an option available to everyone at an affordable price while also educating people on the best way to achieve energy efficiency.
