Objectives.
To provide a conventional family home complete with self
sufficient and environmentally benign technologies.
The home to achieve low energy demand goals and to fit
the land visually.
Site.
20ha of past grazing land already extensively revegetated
and fitted out with dams and access road.
The land forms a valley in the overall landform with a
predominant northern orientation. The landform to the west
of the land forms the hillcrest and is developed as public
pine forest.
The buildlng site is on the end of the access road at the
north-west portion of the land, with a steep eastern slope.
The land has extensive clay soils.
Construction.
The building is a conventional timber framed structure with
fibre cement board cladding externally, plasterboard and
cypress pine boarding claddings internally.
All walls and roof are insulated.
The design incorporates a sunroom complete with pergola
incorporated within the fascia line, with adjacent clear
roof over the entry for maximised solar gain to that portion
of the home.
The fascia pergola ensures full sun inflow in winter
months progressivley shading to full sun exclusion in
mid-summer.
Extensive verandas shield the building face from weather.
The kitchen has a steep roof and clerestorey.
The land slope is accommodated by a building split level
occuring between garage and bedrooms.
The building is painted light cream to match stone walling
on embankments nearby, with Mist Green roof and Caulfield Green
trim and fascias.
Systems.
Water supply is from a 20,000 gallon concrete tank by pump to
the house. Rain water is delivered to the tank from the building
roof by a wet downpipe/stormwater/delivery pipe syphon system.
Hot water is by roof slope mounted solar system with
DC ignition to gas boost.
Electricity is from solar photovoltaics on the roof and wind
turbine on the northern boundary, both providing electricity
to battery storage on the northem veranda and split 12V, 24V
and 2kW inverter for 240V AC to zoned circuits around
the building.
A ceiling fan in the clerestorey void circulates air in the
open living/sunroom/kitchen space.
A wood stove provides space heating, a gas stove with
exhaust hood for cooking.
Occupation.
Comfort is maintained by manipulation of openings and systems.
Garden is to be developed to support the climate response design
of the building.
