This house is primarily a retro fit demonstration for existing/traditional/standard homes that shows what are the cheapest/DIY options to make it 8.4+ stars.
Utility bills, building performance data and methodology will be on display: zero gas, zero mains water, and < 5kW hr electricity use for large 3 BR, 2Bath house.
The home itself demonstrates the basics of low energy design: square, with good cross ventilation, good solar gain and multiple adjustable/seasonal shading initiatives, water tanks, super insulation, multiple organic waste options, and multiple internal zoning options.
It also has a few Novel technologies (things not common in other low energy houses) including: ground coupled geothermal cooling (DIY), solar space heating (DIY), off grid PV with battery storage, on grid PV maximized for winter gain and subfloor refrigeration booster. All have been featured in RENEW magazine articles.
Super insulation is used strategically (slab/ducts/skylights/windows) retro fit thermal mass, dual system grey water reuse, retrofit solar hot water, plug in hybrid Prius conversion – ethanol/ electric, electric bike, Sky- wall, Olive Pit pellet heater for zero carbon heating, heat pump hot water, real time power metering, thermal camera demonstration (not 2015), active and passive solar chimneys and solar furnace demonstration.
New features for 2015 include a double insulated front door, double insulated hot water storage, completed sky wall (9m2) a new whole of house solar furnace space heating (20+ kW) -DIY, and a solar coffee table! In the garden there are fruit trees and the beginnings of an edible garden. There are also frog bogs, bird baths, insect hotels, bat boxes, bird boxes, possum boxes, and a lizard lounges for the critters.
I look forward to seeing you on the day.
