Judging Criteria

Judges look at three main criteria that entries must demonstrate. These are:

  • Regeneration
  • Reconciliation
  • Restoration

Project entries are required to demonstrate how they make the world a better place by minimizing the environmental impact of building. The projects are also required to bear the hallmarks of great architectural or social design. Entries are submitted under two categories, one for built work and the other for works of social importance, including research.

Here is the the full range of entries

expresso

Friday morning at about 7:05 South Africa time I will be interviewed on the the national morning show Expresso.  Eeks, its one thing to partake in a film where you can re-shoot any mumbling or lame moments.  Live TV is a terrifying prospect.  Send me all your positive energy please!!

The awards are to be announced tomorrow evening October 27.  Watch this space.

And finally, our enormous pit that will house the water harvesting system.  This HUGE project is so exciting and the technology so amazing it will get a post all of its own.  Suffice to say its 9m X 3m X 2.5m deep and has taken weeks to build.  Happy to report that not a grain off soil went off site, its it the roof garden and being spread around the property.  Watch this space!

Photo Update

With 5 working days to go until move in day, nerves are a little stretched.  One can’t help noticing that there is still no sign of any part of the kitchen, a toilet, tap, shower rose and one or two other rather important things that one gets used to. We must live in faith though that it will all come together and in the meantime this post will celebrate what has been happening at the Gorgeous Green House.

Owl House

Owl House

We are very excited to have installed the owl house.  You may think the design looks a little ‘open’ and are wondering why it is not in a tree.  We wish to attract Spotted Eagle Owls as we know they fly in our area and according to the experts they want to nest where they will have 360 degree clear views.  We’ve installed ours in the roof garden so we can lie in bed and watch all the action.  Just waiting for a broody pair to move in. Click here for designs for this and Barn Owl houses.  Very easy to make. I’ll allow the photos to tell the story of the updates.

Green Concrete: an oxymoron? (plus pics of our polystyrene process)

DSC00073There is no doubt that concrete is a filthy substance to produce. Worldwide, it is the most widely-used construction material with over ten billion tons produced annually and it carries a massive CO2 burden – in total about 7% of global CO2 emissions come from concrete production.

On ‘round one’ of the Gorgeous Green House design we were rather shocked to learn how many truckloads of concrete would need to go into the building.  We began looking at alternatives:

Fly-ash concrete is readily available in many countries. Fly-ash is a waste material – the inorganic residue – that remains after pulverized coal is burned in coal-burning power plants. Disposing of it can be a problem. Fortunately, the construction industry has discovered that fly-ash can produce a superior concrete with excellent finishing characteristics.

Recycled aggregates and lightweight aggregates can replace the usual sand and gravel in some concrete applications. This can consist of crushed concrete, brick, or crushed glass. Lightweight concrete is made by using expanded volcanic materials – pumice and perlite, for example – to replace some of the usual stone aggregate.  Volcanic materials also add some thermal insulation value to the concrete. Unfortunately this is not yet available to us in South Africa.

There are also interesting products in R & D using for example waste products from oil refinement with huge CO2 emission reductions in the production process. Not yet available.

Traditional alternatives such as timber construction could also be considered.

So what did we do?

Polystyrene ready to go

Polystyrene ready to go

Firstly, we lost as many flat could roofs as we could to be replaced with timber trusses and metal sheeting.

A much larger percentage of concrete to be used though, is in the slab between the floors, the off-shutter wall and supporting the roof garden so we turned our attention here.  The roof garden was non-negotiable as the structural support required doesn’t provide any options.  We could have put timber flooring in elsewhere but it would be heavily treated for termites, noisy and aesthetically not in keeping with the contemporary design of the house.

The awesome British show Grand Designs provided inspiration.  Polystyrene is being used in conjunction with cement to reduce the volumes required.  Timber formwork is fiddly to make and a lot of it cannot be reused. Using polystyrene in place of timber effectively kills two birds with one stone: it acts as formwork to mould the concrete and is then left in place to provide insulation.

First phase off-shutter wall

Polystyrene beads can also be added to a concrete mix but our engineer was not happy with the structural support this process would provide.

So our green guilt is somewhat reduced and we are also reminding ourselves that concrete lasts. This is the stuff the Romans and Egyptians built their empires with!  It’s impermeable to air and wind-driven rain. And concrete is inedible, so bugs and vermin can’t gnaw at it. A building with exterior concrete walls can also be energy-efficient, especially in climates that have daily temperature fluctuations. Even though concrete provides little insulation, it creates thermal mass that can store warmth or cold, reducing indoor temperature fluctuation.

Check out our polystyrene process and stage one of the off-shutter wall.  Concrete is being poured on Monday 05-08 Another significant milestone achieved. Very exciting!

Green Demolition Can Be Easy and Fun

IMG_4969

Slate roof conserved for another home.

One of the least green aspects of building or renovating is the waste that is created.  Figures from North America estimate that 3 600 kg of waste are typically thrown into the landfill during the construction of a 700 square metre home. Landfill operations are generally under pressure and are expensive.  Transportation to sites, normally at a distance from residential areas, increases the carbon footprint of a project. Waste from sources such as solvents or chemically treated wood can result in soil and water pollution.

Doors, sink etc to be re-used

Doors, sink etc to be re-used

What I’ve learned is that it is really easy and fun to minimize waste. Many  materials can be re-used. I’m saving items such as doors, stainless steel sinks, balustrading, metal gates curtain rails etc to put into the new house.

Oregon floor gone to new home and cavity to be filled with rubble

The Oregon floor has already been lifted and installed in a new home.  The slate tiling is being carefully stacked for the same.

The cavity left in the floor will be filled with the rubble from the walls to be demolished.

Brick paving will be reinvented to veggie planters

Re-purposing other materials just needs a little planning. For example, all the brickwork in the garden is being lifted and stacked to be reincarnated into veggie planters.  All decent solid wood from cabinetry and shelving will be re-used for storage units.In South Africa we have programmes whereby flourescent light bulbs and old shower heads can swopped for LED’s and energy-efficient products, green and economical.  Great combo!

Conserving/protecting Pavetta lanceolata with fence. Thanks team!

Perhaps the greenest aspect of Day 1 of this project was measures to conserve.  A fence has been built around our precious Pavetta lanceolata (Bride’s Bush) which is located where it could easily get destroyed.  Thanks Pretty, Wise and 3rd person (still to learn name).  I appreciate that traditional building practices are not very sensitive to the vegetation on site and it means a great deal to us that these measures have been taken.

Lastly, the easiest and most fun part of green demo is donating the multitudes of materials that don’t have much resale value but are desirable to many. Friday was the first day of our build and it is clear that everything from the old melamine kitchen, windows, doors, in fact all manner of materials will find new homes.  People were literally walking in off the street asking what they might have.  So no excuses, South Africans.  We can massively reduce our contribution to landfill and help out a few people at the same time.
