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)

Brett's house features:

7.2 stars on the NatHERS rating 

Bondor construction

Sanden heat pumps for hot water

Heat pump hydronic heating, through skirting 

Very well sealed, with an air change rate of 2.05 per hour, which is equivalent to the best standards internationally (for naturally ventilated homes)

NO GAS connection

induction cooktop

3kW PV system 

... and much more!

Queeensland University of Technology (QUT) is collecting one year of opearating data on the whole house, as well as individual circuits, and analysing this for a report due out soon.

Positive moves towards a sustainable society

Brendan Condon is Managing Director and co-founder of Australian Ecosystems, an integrated company specialising in ecological land restoration. He is also Director at The Cape sustainable housing project and Biofilta Stormwater Solutions

Brendan Condon believes we have been "sitting on our hands" regarding matters relating to climate change for too long and ignoring the urgent need for a serious vision for the future. Who could argue with that? Certainly the P.M. would agree that this is an "exciting time"  but they would have amazingly different paths. Brendan has chosen to develop the means of capturing and re-using the storm water that we see flowing down our gutters carrying all the rubbish into the Bay, instead to capture the pollution by means of a plant filtering system. One of the largest of these systems of returning and re-using this water is in the Fitzroy Gardens in Melbourne.

Another of his areas of challenge and developed expertise is the development of good design in sustainable housing (e.g. The Cape Paterson sustainable housing project). He points out that apart from environmental grounds there are marked improvements economically with the rise in the price of gas coupled with the drop in the price of solar.

Other projects of interest include the development of vertical and horizontal gardens useful for city dwellers for urban food production, community gardens, autonomous electric vehicles (probable in the next decade), when one can read a book on the way to work!

All this should be of interest to anyone planning a home, living in the city or merely caring about the importance of food and water and waste management for the present and the future.

Adrian Whitehead calls for climate action!

Beyond Zero editorialises ahead of the multiple climate rallies and Paris climate negotiations as a preamble to talking with Adrian Whitehead a climate campaigner currently advising Australian agricultural systems to intergrate bio char, which is a well known soil enhancer and carbon sink.

Benjamin Mandel - LBNL - talks cool pavements

Today we talk to Benjamin Mandel from the Heat Island Group, Lawrence Berkeley National Laboratory (LBNL) to discuss cool paving and their cool schoolyards initiative which seeks to incorporate these solutions in schoolyards.

Ben talks to BZE's Matt Grantham and guest interviewer University of Melbourne's Chris Jensen who is working on similar projects at the University's faculty of Architecture, Building and Planning.

Doug McClenahan, Project Leader of the Drake Landing Solar Community

Doug McClenahan is Project Leader of the Drake Landing Solar Community (DLSC) and Natural Resources Canada’s Manager of Active Solar Research and Development. District heating at the DLSC is provided by seasonal solar thermal energy storage. Solar thermal energy is collected in the summer, stored underground, and then returned to the homes as heat during the winter.

Doug says 97 percent of space heating needs for the community’s 52 single-detached homes were met by solar thermal energy last year, a feat unprecedented anywhere else in the world. He is planning for 100% solar this year, which is its sixth year of operation. The energy efficient homes are very well insulated and air tight. 

An array of 800 solar panels located on garage roofs throughout the community generate 1.5MW of thermal power during a typical summer day and supply heat to the district heating system. During the warmer months, the heated water is distributed from the short-term storage tank to the borehole thermal energy storage (BTES) system via a series of pipes. As the heated water travels through the pipe-work, heat is transferred to the surrounding earth. The temperature of the earth will reach 80 degrees Celsius by the end of each summer. In winter, the heated water in the bore hole field passes to the short-term storage tank and is then circulated to the homes through the district heating loop to provide space heating to the homes. 

Natural Resources Canada won the 2011 Golden Energy Globe World Award for the DLSC project, the first time a Canadian project has achieved such a distinction.
