ABOUT GREEN HOUSE


PROJECT EXAMPLES

Cavity Brick - Highlands, Victoria Designed for passive solar efficiency. Insulated cavity brick external walls and cavity brick internal walls for thermal mass to absorb solar radiation between early March and late October, providing natural heating in winter months. Timber floor insulated with concertina foil. Double-glazed, timber-framed windows from Paarhammer Windows. Ceiling insulated with R 2.5 batts with concertina foil overlay. Ceiling fans. Glass aspect 20 degrees east of true north with eaves’ width being 50 percent of window height, so no sun accesses north windows between mid-October and early March. Recycled French doors.

Weaknesses - more than optimal glass on the east and west aspects. Recycled French doors cannot be draught sealed. Use of South-East Asian rainforest timber decking (Merbau).

Timber and Mudbrick Homestead - Murrindindi,
Victoria

Northern aspect for maximum solar penetration in winter, concrete slab and mud-brick internal walls for mass, radially sawn weatherboard clad on timber frame, double glazed windows in timber frames. Recycled bridge timber posts and beams. Solar hot-water system. Stone wall material reused from previous homestead. Recycled bench-top timbers.

Rammed Earth Homestead - Murrindindi,
Victoria
Northern aspect. Materials chosen to blend with the surrounding environment. Concrete slab and rammed earth walls for thermal mass. Recycled brick paving. Solar hot-water system.

Weaknesses - uninsulated thermal mass (rammed earth) used in external walls. Effectiveness of slab reduced by timber flooring laid over slab.

Shadowclad (Plywood), Studio/Garage- St Kilda, Melbourne Passive solar design. Recycled timber used for windows, stairs and floors. Double-glazed windows. Excellent cross-ventilation in top-storey studio, using floor vents on cooler south side. Ceiling fans. Bio (natural pigment) paints.

Weakness – no thermal mass.

Steel Construction Homestead - Yarck, Victoria Designed for passive solar efficiency. Floor - exposed polished concrete, insulated perimeter and base. Steel framed, Colorbond steel cladding. Windows – double-glazed, argon-filled, evergreen tint to reduce glare, aluminium frames. Glass aspect is true north, with eaves’ width being 45 percent of window height, so no sun accesses north windows between mid-October and early March. Exposed slab provides thermal mass to absorb solar radiation between early March and late October, providing natural heating in winter months.

Weaknesses – non-thermally broken aluminium window frames allow heat and cold transmission through frames. Steel frame transfers heat and cold through walls and roof to greater extent than timber, even with thermal break between frame and cladding. Note: steel used for design flexibility.
