The system was installed by Australian owned company, Solgen Energy, to connect to an array of existing solar electic panels to create a combined 48kW solar energy installation. The additional 36kW array of 216 photovoltaic modules generates up to 58 megawatts of electricity a year and reduces Council’s carbon emission by 58 tonnes of CO2 per year.

Randwick City Council has installed 20 kilowatts of solar panels at other Council sites and has undertaken other sustainability initiatives including large water conservation projects as well as introducing a community car share scheme that includes designated parking for both car share and hybrid vehicles at popular shopping and beachside locations.

Council makes use of an environmental levy to fund the Sustaining Our City program that incorporates a Local Greenhouse Action Plan and a range of community education initiatives such as the annual Eco Living Fair, Sustainable Gardening course and Living Smart course.

In 2010, Council’s Sustainability Education Officer, Fiona Campbell, will oversee a project to retrofit for energy efficiency, water efficiency and public education the Randwick Community Centre. The project will see the installation of simple technologies to reduce energy and water consumption and feature interpretive signage and education programs, including the PIG — the Permaculture Interpretive Garden — to offer visitors and participants in council courses ideas that they can implement in their homes and apartments.

Rating

INNOVATION/DESIGN THINKING: Medium.

A solution to carbon emission reduction.

SCALABILITY POTENTIAL: High if roof space and funding available.

REPLICABILITY: Can be copied easily with existing technology.

The booklet carries the rather intriguing title of A Good Home Forever. It proposes that we respond to economic downturn and the crisis in sustainability by taking control of our lives and by examining what it is that we want in a home.

Rosemary describes conventional homes as ‘consumer junkies’ gulping down resources and producing only wastes. Yet, Rosemary’s solution isn’t to go out and commission an architect to design a state of the art energy efficient house such as we see in those ‘green’ magazines aimed at the well-off. Not all that many can afford to do that.

Rosemary suggests converting — retrofitting, in the jargon — an existing house to make it energy, water and materials efficient. It is the reality that it is the retrofitting of existing housing stock that will make our cities energy and resource efficient.

A book based on personal experience

This is the theme of her booklet — the retrofitting of a brick veneer, suburban house. Brick (and alumimium window frames and galvanised iron roof), because it is a low-maintenance material. Brick veneer so that Rosemary could easily remove interior walls to open up the place and so that her slow combustion wood stove could warm the interior during Katoomba’s chilly (let’s be honest here and say freezing) winters. Reading this, I was reminded of something that Jude Fanton from the Seed Savers Network said about buying a house in Byron Bay. Brick veneer, she told me, is the best buy because such houses work well in the subtropical climate. This leads to the question as to whether the much-derided brick veneer is the housing style for all climates.

Rosemary’s booklet is not simply about a retrofit to adapt her home to the seasonal variability of climate in Katoomba, high in the Blue Mountains west of Sydney. Embedded in it is a philosophy of life, such as assessing whether you move to more affordable premises or stay where you are, and making choices and setting criteria.

Not all that many years ago, Rosemary moved from a larger property at Blackheath, further up the mountains, to her present home in nearby Katoomba. In doing so she made the choices about the criteria for sustainable urban living that her book focuses on:

• solar access (the house faces the north, to sunward, affording access to solar energy)
• energy autonomy
• water sustainability
• proximity to services — Rosemary can walk to the train station, and she is close to amenities.

There was also the criteria of financial sustainability because she didn’t want her money tied up in a mortgage. As Rosemary says, by moving to a lower priced home you might be able to free yourself from financial anxiety in these economically troubled times, or at least set yourself on the path to doing that.

There’s a lot to learn about site analysis in her booklet and there are several site design plans. She covers the permaculture concept of designing by zones according to the frequency of access needed, energy principles derived from the permaculture design system and harvesting and storing rainwater. She even lists costs and offers a checklist to think about your home.

May I suggest that this would be useful reading for people reconsidering how they live?

It is, in essence, an ideas book and it carries that critical, analytical and self-assessing attitude that is embedded in the permaculture design system, of which Rosemary is a noted educator and exponent.

CD useful to educators

The book has an accompanying CD with a 20 minute or so video of Rosemary’s retrofit, produced by the local Lysis Films in Katoomba. It also has segments, potentially of use to educators, about particular elements of the retrofit. These run only a few minutes each and are sufficiently short to be of use by sustainability educators in workshops and courses.

The full 20 minute video would provide an informative case study as a leader to start a conversation on home energy and water efficiency. Educators would show it, then use the content as the basis for an ORID format (objective, reflective, interpretive, decisional) or other guided conversation.

In this way, the video works in the same way as Morag Gamble and Evan Raymond’s 15 minute production on local foods does as a leader for discussions about food systems. We have a number of longer video programs, but too few of this length that is suited to public events and sustainability education workshops and courses and that are also available on DVD for public showing.

Having said good things about the video, do I have any suggestions for improvement? Well. yes I do. I found that the video had too much footage of talking heads. You do need some of this, however more video of the works Rosemary has carried out and footage of some of them in action would have been useful.

Really a book outline

Putting on my editor’s hat, my impression after reading A Good Home Forever was that this is the outline of a more detailed book. The bulleted points in it — and Rosemary makes extensive use of these — could in many cases be expanded. Although she might have covered what a more ambitious book might contain in her The Earth Users Guide to Permaculture, an expanded A Good Home Forever would apply that to the specifics of her Katoomba retrofit.

But would there be a market for such a book? I think so, and the reissuing by David Holmgren of his case study, The Flywire House, is evidence for this. Looking at the environmental/sustainability shelves of good bookshops, I see a variety of personal experience titles about people trying a 100-mile diet, moving the Mullumbimby to avoid a peak oil crisis or moving to the countryside. And while there are also plenty of titles dealing with resource efficient home design, there are too few case studies.

The difference with Rosemary is that she moved into a small city rather than escape to the countryside, in doing so emphasising the reality that urban living can be the catalyst for sustainable living.

The book, which is printed on recycled paper, is illustrated by Rob Allsop, who did the drawings in The Earth Users Guide to Permaculture. To reduce paper wastage, Rosemary made use of the inside of the cover for acknowledgements and some text. These are usually blank pages in publishing and I like it that way. There’s something odd about reading text on the insides of the cover and I don’t think it works well.

Rosemary sells the book alone for around $5, but for a mere $20 you get book + video CD. This is a complementary, useful package. And if you think that’s a lot for a CD and a 24 page booklet, think of its value this way — the cost is equivalent to only six cappuccinos, and its effects are likely to last a great deal longer.

Postscript: Following the launch of Rosemary’s book, Transition Blue Mountains held a seminar of home retrofitting for resource efficiency in Katoomba, attracting more then 100 people. Rosemary’s CD was shown at the event.
