Why the ‘Greeny Flat’?

We built the Greeny Flat because we believe that the time has come to move towards a fossil free future and to build small, simple structures that meet our needs without compromising the ability of future generations to meet their needs. We’re hoping to show that it can be easy and affordable to build an energy positive house, i.e. one that makes more energy than it uses, which will allow us to live comfortably in harmony with our environment. If we can show that anyone can achieve this then the question really becomes, “Why not?”

So what exactly is a “Greeny Flat”?

Is it a flat for green grannies or a granny flat for greenies?

WELL… you could say that a Granny Flat is a shack out the back where Granny can finally relax in the relative peace of the backyard after a lifetime of serving others.

A ‘Greeny Flat’, on the other hand, is a small, affordable, infill home designed and built to be as sustainable as possible. And, while it is perfect for a mature lady with grandchildren and a limited income, it is really designed for anyone who cares about protecting the planet and living comfortably within their means. A big part of what makes it ‘affordable’ is the low operating and maintenance costs which add up to huge savings over the life of the home (and its occupants) and a big part of what makes it sustainable is making it ‘energy positive’, i.e. it should produce more energy than it uses over a year.

The particular Greeny Flat in question is a full-scale living experiment currently underway in Mittagong, NSW, to see if it’s possible to build a small, comfortable, healthy, energy positive, low-maintenance, fire-resistant, water-efficient, elderly-friendly infill house at an affordable price.

It was conceived, designed, and built by Andy Lemann with lots of help from Jane, Martin, George, and Cate Lemann and Cintia Yamane. It’s based on a Triple Bottom Line philosophy which aims to improve the Environmental, Financial and Social outcomes of the choices we make. Now that construction is complete, Andy and Cintia are living in it for at least a year and monitoring the energy performance, water usage, water quality, indoor air quality, and comfort to see whether it actually meets the goals. There’s a lot of hype (i.e b__s__) in the ‘Environmentally Sustainable Design’ (ESD) and “Green Building’ fields. Lots of extravagant claims made about ‘net-zero-energy’ performance and lofty sustainability credentials. We think the literal proof is in the proverbial pudding. If, at the end of the year, the Greeny Flat has made more energy than it’s used, conserved water, and remained healthy and comfortable inside without any additional heating or cooling, then we’ll call this experiment a success. And of course we’ll be able to report on the costs associated with building and operating the place over the year too. Whether or not it’s ‘affordable’ will be a matter of opinion so we’ll leave that to you to decide.
