8.2 Star home ready at Cape Eco Village
The Cape Eco Village is underway with the first home achieving an 8.2 Star Rating.
The development at Cape Paterson, around an hour from Melbourne’s south-eastern suburbs, will see 219 homes built at a minimum 7.5 Star rating with onsite solar energy, rainwater and stormwater use. The Cape Eco Village is designed to operate without the use of fossil fuels and to export an annual surplus of clean energy to the electricity grid.
This home has been built and fully fitted out by Wonthaggi builder TS Constructions. To encourage the uptake of climate ready housing The Cape project team commissioned 10 additional home designs, prepared and costed by architects and builders. These concepts are downloadable from the project website www.liveatthecape.com.au and have been downloaded over 25,000 times in the past 12 months.
The demonstration home is a four bedroom, two bathroom, 196 square meter double story dwelling that reached the 8.2 Star rating with a range of sustainability features. The home features 5 kilowatts of solar energy, insulation, thermal mass, double glazing, strategic shading, electric vehicle charge points, clean energy for heating, cooling, cooking, lighting, 10,000 litres of rainwater storage, raised water efficient food gardens, efficient white goods and is designed to operate without the use of fossil fuels.
The 5.0kW solar photovoltaic system has been installed with solar panels supplied by Trina, inverter by Sunnyboy and Digital Energy Monitor to show energy generation and use. A Sanden hot water heat pump system has been installed which reduces up to 78% of hot water energy needs compared with a traditional system.
The home has been fully insulated with external walls having R2.5 insulation, ceilings under the roofline are insulated to R5.0 and between floor insulation of R3.0. All insulation is earthwool batts.
All windows and aluminium doors are double glazed aluminium units with low-e glazing, and all window and door openings have a 20mm compressible bead applied between the building frame and the unit, minimising any air leakage.
Fixed pitch, aluminium blade window shades, designed and manufactured by Sunex, have been installed on selected first floor windows to reduce thermal heat gain in summer while allowing for thermal penetration in winter. A timber pergola has been built on the lower level to achieve the same result.
The flat roof, parapet wall design does not allow for eaves, however the developers say the louvre shades and pergola achieve a better result on the northern elevation, whilst the west elevation has no windows.
The home includes extra thermal mass via rammed earth blockwork walls using locally-sourced gravel pressed on site.
Every garage is fitted with a dedicated 15amp charge point in the garage. This point suits most common brands of EV vehicles including Nissan and Mitsubishi.
