Double glazing

The reduction of extremes in heat or cold without continually increasing power consumption

The answer is provided by Charles Rendigs, the National Business Development manager of "Thermoshield", an Australian company developed and owned, situated at Dandenong. It is a coating for roofs that can be painted or sprayed on, can be coloured by mixing with  red or green paint. White of course is generally used when a high  solar reflective index is desired i.e. in Summer but as it ages its capacity to reflect is naturally diminished.

But Thermoshield can also be used to retain warmth inside in the Winter months i.e. as a form of insulation producing what is called "dead air" space so its properties can work to either reflect or absorb. It can be used in conjunction with  PV as PV usually only covers part of the roof and may heat up around the cells. It can increase the productivity of cells during the day. It can also be complementary to pink batts. air conditioners and other forms of temperature control.

It has been tested by CSIRO and has been used from Queensland to Melbourne. It sounds like a robot acting as instructed!

Students of Sustainability Conference 2013

Beyond Zero's Nick Carson visits the 2013 Students of Sustainability (SOS) Conference, a national wide conference which was held at the University of Tasmania from the 5th to 9th of July.
Throughout the past twenty-one years, SOS has grown into the primary national environmental conference for students. Held in a different city every year, SOS spreads its unique, life-affirming, change-making energy to the Universities and communities that host it.

Retrofitting Bonanza

To coincide with the launch of the Zero Carbon Australia (ZCA) Buildings Plan in August 2013, Beyond Zero Radio looks at transforming our buildings to zero emissions.The ZCA Buildings Plan is the first comprehensive, nationwide retrofit plan for Australia's building sector. This plan demonstrates how all existing buildings can reach zero emissions within ten years.

Beth talks to Lucy Roberts, BZE Live Retrofit Productions Manager, about the Master Builders Association's Build & Renovating Expo held in July 2013. Lucy ran a set and live performance at the Expo, where an average Australian house was transformed into a zero-carbon, low-energy, high-performance home, showcasing the solutions of the ZCA Buildings Plan. We also talk to a range of exhibitors promoting energy efficient products at the expo.

Trent Hawkins, ZCA Buildings Plan Project Director, explains how retrofit existing buildings for higher comfort and lower running costs can halve Australia's building energy use. Then we talk to Lloyd Niccol, Project Manager Team UoW Australia, the first team from Australia to gain entrance into a Solar Decathlon 2013 in China and the first in the history of the competition to demonstrate how to retrofit an existing home! 

UPDATE since the interview with Lloyd, is Team UoW has won Solar Decathlon 2013 - congratulations!
