Foxcliffe has it Right: A Land Development for the 21st Century

If most Australians were aware of what was going to happen to Planet Earth this century, they would be lining up to buy a house and land package from Mike Hulme. His Foxcliffe development at Witchcliffe, near Margaret River, Western Australia, has it all. Having worked with Mike for many years on many land subdivisions, I know he is fully aware of how to design a sustainable residential subdivision and set guidelines that work.  It is imperative that solid guidelines are attached to property developments to deliver outcomes that are a win for the residents, the community and the environment, by reducing energy and water and conserving the natural world.

Joining forces with a real estate development giant with such high ethics as the Perron Group is also a smart move for all involved. It gives the project the financial clout it needs to succeed. Whilst so many dream, very few successfully act and deliver. Mike Hulme is one of those people. Hulme always commences his developments in the right way. He starts by considering the needs and best interests of the community.  In Margaret River, not everyone is a retired real estate agent or doctor, or has a large bank account.  They may not be rich in financial resources but they are good, down-to-earth people who greatly appreciate nature and want to help co-exist with it. Unfortunately the huge explosion in the demand for large expensive houses by those mainly benefiting from the mining boom in Western Australia, has pushed up consumption, energy use and the sizes of houses. Refer to our article ‘Politics of Housing in the Western World’.

Affordability and the Environment

With building costs skyrocketing over the last few years, many people have had the dream of owning their own home all but destroyed.  Mike Hulme decided from the beginning when buying the land, to not only to do something for the environment, but to also tackle the issue of affordability.  By producing correctly designed, small blocks as part of a wider community, he has combined economies of scale and collective action to reduce the costs of a house and land to within the reach of the average person in the region, as well as to make it attractive for similar people in the city to opt for an alternative style of living. His timing is impeccable as usual, with energy use set to increase by 50% world wide just compounding the greenhouse effect, and producing huge increases in energy prices in the next couple of decades, as all known sources of energy are depleted. His planned lifestyle for the residents may be ‘alternative’ now, but won’t be  for much longer. If the world keeps going the way it is, then we are going to need more of this style of living.  The growth of energy use and the depletion of the world’s energy resources will ensure that conventional lifestyles will not be afforded by anyone except the ‘stupid’ rich, and those lacking public consciousness. Refer to our article on world energy and population trends for the rest of the century: ‘Energy Consumption Growth

Healthy food and fresh clean water is the key to a healthy life and through cutting-edge water technology and productive landscaping, Foxcliffe will deliver these  precious commodities to all of it’s residents and food and water bills will be kept to a minimum.  This will be a great environment to bring up children and create a generation of socially and scientifically, sustainable people.

Sustainable Community Living

Perron & Hulme Developments have had the good sense to enlist Josh Byrne, environmentalist and expert sustainable landscaper and gardener, to ensure that the gardens and landscape are designed in detail to complement Mike Hulme’s vision for the estate. Asked what was the vision for the development Mike Hulme answered as follows: “The vision for the Foxcliffe Farm Ecovillage is to create a world leading sustainable community in Witchcliffe.  The village will comprise 180 strata titled home sites with an extensive range of onsite infrastructure and services to create a world-leading example of sustainable development that achieves:

  • 100% net power generation on site with solar PV and wind turbines,
  • 100% self sufficiency in water through onsite rainwater harvesting,
  • 100% production of seasonal fresh produce on site,
  • Class A recycled water for household garden and toilets,
  • all homes to front expansive open space and community gardens,
  • high efficiency, solar passive homes,
  • affordable house and land packages,
  • onsite wind turbines to provide free charging for up to 100 electric vehicles,
  • a  local energy grid that employs smart grid technology.

Solar-e endorses Foxcliffe

We at solar-e.com are pleased with this initiative and wish Mike Hulme every success for the project.  Solar energy in the forms of passive solar design of the houses, photovoltaic panels and solar water heating will form a lynch pin to make this development a truly ‘micro solar’ economy, when combined with the organic approaches to water collection, grey water and waste recycling, and the generation of bio fuels courtesy of the greatest energy gift, the sun.

The consequences from this development will be far reaching.

Energy Efficient House

Energy Efficient House: Design Recommendations

An energy efficient house which offers a recognised standard of energy and comfort, will have the following important features incorporated into its design:

  • It is correctly orientated to the sun (southern hemisphere locations require a northern orientation)
  • The window glass area and window placement have been scientifically calculated
  • Walls and floors are made from a mass material that is suitable to the climate of the area
  • Insulation is correctly placed and of the exact R rating for optimum effect
  • There is adequate natural ventilation, related correct window and door placement

Energy Efficient House by Ecotect Architects

House Orientation

The majority of blocks in a housing estate should encourage houses of a rectangular shape with long axis close to east-west. Generally, the ratio of long to short axis must be more than 1.5. This will afford maximum privacy and cost efficiency. In cold climates the proportion will be longer but in hot climates for an energy efficient house result the shape will be more of a square than a rectangle.

Window Placement

In the southern hemisphere the living area should face north and have the largest window area. Conversely the northern hemisphere, living areas should face south. For the purpose of clarity, in this article we will presume the location of the energy efficient house is in the southern hemisphere. Windows should be shaded in summer but be free of shading in winter. The shading type can be adjustable or permanent – such as eaves, awnings and shutters.

North Walls

North facing glass should be clear. Avoid tinted glass in temperate climates. Fixed shading should have a specifically calculated overhang. When calculating the area of glazing to the north it is wise to restrict it to no more than 35% of the effective floor area in temperate climates. In colder or warmer climates the ratio is adjusted accordingly. For an energy efficient house to work well in all seasons, pergolas with deciduous plants or creepers, or shutters and awnings which are adjustable are preferable to a system of permanent shading. It is important to allow winter sun to enter the energy efficient house, therefore permanent shading should be avoided.

East-West Walls

In order to restrict the sun access, windows in the east and west walls should be minimised – or shaded to prevent the sun from entering. Shade structures are not useful for the east and west walls. The area of glazing should be restricted to less than 5% of the total floor area for both of these walls combined, with the western wall to account for no more than 2% of the total floor area. Allowances may be given if the other elevations use more than the minimum amount of recommended shading. The allowances will be calculated by a specialist in energy efficient house design. There are specific maximum co-efficients of shading which must be included in the calculation. Variations will be made for each climate.

Shading

Climbing deciduous creepers, deciduous trees and plants are recommended to shade east and west windows. Adjustable shade controls and tinted glass is also recomended for windows in the east and west walls.

South Walls

It is not required that windows in the south facing walls are shaded – if shading is used it should be limited in order to maximise winter sun benefits. The east, west and south facing glass areas should be restricted to a maximum of 15% of the floor area. Shading these areas will not allow this restriction to be lifted in a temperate or a cold climate zone. It may be found by using a computerised thermal analysis, that reflective or tinted glass may be used on south facing windows.

Stabilising Internal Temperatures

It is important to use the right materials in the construction of an energy efficient house – these materials differ from climate to climate. In a temperate climate, materials which absorb and store heat well, such as brick, rammed earth, rammed limestone and concrete, will provide stable air temperatures, especially in the hotter seasons. Construction should be on a concrete slab. Hard surface flooring materials, which absorb heat, are recommended specifically for north facing rooms. Coverings such as tiles, slate or polished concrete will continue to work over a 24-hour period. In extreme weather conditions, doors and windows should be kept closed.

Insulation

In a temperate climate the roof insulation should be a minimum of R1.5. and if perimeter walls are of light weight they must have insulation with an R value of at least 1.0. Under extreme climate conditions these rates may increase to over R4.

Ventilation

To keep an energy efficient house naturally ventilated, the natural breeze patterns of the area must be considered. Windows and doors in the sleeping and living areas must be placed to capture the natural flow of air. Doors to the exterior of the house or rooms with high-flow fixed ventilation like bathrooms and toilets should be weather stripped. To prevent heat loss in winter, chimneys should be provided with a damper.

Hot Water System

The hot water system should be either gas or gas boosted solar. During long periods without adequate sunshine, the gas boosting will be required to maintain a steady supply of hot water. By combining these guidelines and working with energy efficient professionals, your energy efficient house will be cost-effective to run and work to the highest standards of comfort and energy efficiency.

Energising SEA | Renewable Energy Investments

Around the world, growth in renewable energy investments are now greater than any other form of energy source.

Global renewable energy investments are around $US160 billion and this burgeoning of global effort in green energy is underwriting interest in the Energising South East Asia conference
Asia continues to be the fastest growing market in clean tech, with renewable energy investments now in excess of  $US40 billion. For example, China alone now has 42.3 GW of wind power, and has surpassed the US in terms of total installed capacity of wind.

Australia is lagging behind the world in both renewable energy investments and carbon pricing, as highlighted this week by Prof Ross Garnaut in his first update of the Garnaut Climate Change Review. But interest is strong – as it should be in the nation with the world’s best renewable energy resources.

Recent reports suggest Australia has the potential to produce some of the world’s cheapest renewable energy, and to meet all its energy demands by 2050.
