AN OVERVIEW OF THE WORK OF BZE OVER THE YEARS To speak about such a topic, the guest was BZE CEO Dr Stephen Bygrave who is about to embark on a new challenge to join the Queensland government as executive director in the field of environment and climate change.
The work of BZE has encompassed such diverse areas as 100% renewable energy and how soon this may be viable, buildings, battery storage, agriculture including land clearing, industrial processes (such as alternatives in the production of aluminium), and transport to name just a few. In fact BZE has attained worldwide acclaim.
Transport in particular is responsible for 15% of national emissions but the ridiculous dependence on cars in Australia is badly in need of a "mode shift" in favour of public transport and electric cars not forgetting the movement of freight. It is so short-sighted by governments to move freight on the road in lieu of rail which had been achieved in the past. BZE has also written on the topic of high speed rail which has been utilised so successfully in other countries, in particular India and China where there are so many people to accommodate!
So Stephen will perhaps be involved in the different challenges that Queensland can throw up - none bigger than the Great Barrier Reef and Adani and land clearing!

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!
Tim has ideas on 22 ways of cutting power bills and 38% off electricity and gas. He said there is no economic reason for connection to the gas grid as gas has increased in price 75% over the last 5 years! To make the production and usage of hot water go further it is preferable to consider heat pumps and those with smart meters would find it simpler to trace one's usage regularly. It is possible to do this on line for the clever ones (my expression!)
But first on the list is to install LED lights and thereby using less power without heating and these are of course now being offered free of charge. Next it is also a good idea to ring retailers to request what discounts are available ot to threaten to switch if dissatisfied!
But before getting too technical adequate insulation is important particularly hot water pipes and pressure release valves and a commonsense approach e.g. checking for draughts from old fireplaces and vents and the installatiom of old fashioned drapes and pelmets
Michael raised the question of showerheads which Tim said need not be either giving a satisfying shower or be saving hot water but could be both and if not satisfied could be returned! And that green power is provided by most retailers not only Powershop.
Trent Hawkins is Senior Consultant at renewables and energy efficiency consultancy Enhar. He joins Beyond Zero to talk about his latest technical research on Zero Net Energy Towns.

Rob Murray-Leach is the CEO of the Energy Efficiency Council (EEC), the peak body for commercial and industrial energy efficiency. Energy efficiency is one of the fastest growing sectors of the world economy, with HSBC estimating that global revenue from energy efficiency more than doubled between 2008 and 2009 to reach $164 billion. Rob joins Beyond Zero's Anthony Daniele to talk about emissions abatement, demand response, efficient appliances and the effects of the recently introduced carbon price on energy efficiency policies. Rob believes that most businesses can reduce 30- 50% of their emissions through energy efficiency.
Rob has an extensive background in climate change, energy, transport and sustainability, as an author on the Garnaut Climate Change Review and senior policy expert in the South Australian Government. His academic background from Oxford and Adelaide focused on behaviour and sustainability, and he has contributed to a number of texts in this field.
Colin Davis is CEO of Boston (US) based company kWhOURS, developer of Tablet-based data collection and management software for building energy efficiency professionals.
The team of energy professionals and software developers at kWhOURS has the goal of simplifying the data collection process; organize hundreds of pages of notes, lead the inexperienced user through a predefined set of questions, automatically associate photos and audio notes with the parts of the building they refer to, and quite simply, improve the field engineer’s quality of life. The software can cut up to 35% of the time and cost associated with conducting a building assessment. kWhOURS offers solutions for utilities, energy service companies (ESCOs), consultants and facility managers.
The Zero Carbon Australia 2020 (ZCA2020) Buildings Plan aims to demonstrate that there are no technical barriers to zero emission buildings in Australia. A dedicated team of about 50 pro-bono researchers from architects, builders and economists, to engineers, programmers and much more, have spent the last 18 months designing a zero net energy consumption building stock for Australia, through energy efficiency retrofits and zero carbon standards for new buildings.
Through the Zero Carbon Australia (ZCA) research project, public engagement program and the Zero Carbon Communities (ZCC) initiative BZE is encouraging climate change policy and solutions across all sectors that are in line with the latest science and the Paris Agreement's mandate of peaking emissions as soon as possible.
Beyond Zero Emissions campaign seeks to reduce atmospheric greenhouse gases to a level that will enable humanity and our natural environment to thrive and flourish. Website by Media Insights, Studioalto, Dvize and the BZE team.
