This house is primarily a retrofit demonstration for existing/traditional/standard homes that shows 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 < 5kWhr/day electricity use for a large three-bedroom, two-bathroom house.

The home demonstrates most of the basics: 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 not seen in other low-energy houses, including: ground-coupled geothermal cooling (DIY), whole-of-house solar furnace space heating (DIY, 20+ kW), off-grid PV with battery storage, grid-connected PV maximised for winter gain, DIY fresh air heat exchangers and subfloor refrigeration booster. All have been featured in ReNew magazine articles.

Super insulation is used strategically (slab/ducts/skylights/windows), retrofit mobile thermal mass, dual system greywater re­use, retrofit solar hot water, plug-in hybrid Prius conversion (ethanol/electric), electric bike, Sky Wall (9m2), olive pit pellet heater for zero-carbon heating, heat pump hot water, real-time power metering, thermal camera demonstration, active and passive solar chimneys, and solar furnace demonstration.

New features for 2018 include a double-insulated front door, double-insulated hot water storage 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 lizard lounges for the critters.

I look forward to seeing you on the day.
