Industrial energy efficiency

Charles Rendigs


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 Forcey: 22 ways to cut your energy bills

How to save money on power bills

This is a headline which should be of interest to everyone!

Beyond Zero's Kay and Michael speaks to Tim Forcey, Energy Advisor, Melbourne Energy Institute, University of Melbourne talks about 22 things you can do to improve your home’s energy performance. And how to reach the ultimate goal of a home heated and powered by 100% renewable electricity. 

My Efficient Electric Home fb group - join us!

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 - Zero Net Energy Towns

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. This project looks at supporting Australian towns and villages assess and design their own plan to achieve 100% renewable energy over a period of 5-10 years. Trent has completed a report about Uralla NSW which is a Z-NET Case Study Town. 

Trent was the Project Director of the recently published Zero Carbon Australia Buildings Plan at Beyond Zero Emissions (BZE). The report is a groundbreaking new pathway for Australia's existing buildings to respond to the challenges of climate change, dependence on fossil fuels, and rising energy prices. Trent was a research director with BZE, a climate change solutions think tank for over three years, including playing a role in senior management of the organization. He was a contributing author to the Banksia award-winning Zero Carbon Australia Stationary Energy Plan. Trent is a Mechanical Engineer with a background in renewable energy and computational modelling.

Mary Ann Piette, Director of the Demand Response Research Center, LBNL

Mary Ann Piette is head of the Building Technology and Urban Systems department and director of the Demand Response Research Center at the Lawrence Berkeley National Laboratory. Mary Ann speaks about the work carried out within their Environmental Energy Technologies Division and the changes she has seen throughout her 30 year career at LBNL, starting with focusing on building construction and materials to the latest in building automation systems, smart grids and demand response.

Rob Murray-Leach CEO of the Energy Efficiency Council


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, CEO of kWhOURS

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.

Zero Carbon Australia 2020 Buildings Plan

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.
