Brett Mashado

Brett Mashado talks about his passive solar designed Energy Freedom home in the lead up to Sustainable House Day. The site has no gas connection, and running costs are a fraction of their gas bill alone in their previous home. 

Brett and Gilda Mashado and their three children have been living in their home in Mt Gambier SA and collecting energy usage data for almost one year. He is planning to open his home for Sustainable House Day next year (He couldn't, due to work committments, for this Sunday 11 Sep. There are many other houses you can see so check out the website)
