Smart home pays off

Building a home that makes the best use of the natural resources gives Michael Jorgensen a sense of satisfaction.
His next home for his own family will have all the elements that went into a home at Gilgai that won his company a regional NSW HIA award for a green smart custom built house.
Michael and wife, Cate, picked up the award in Coffs Harbour.
Michael said energy efficiency, off-grid homes were becoming more affordable and he predicted they would become more common as people weighed up the economic benefits.
The home in Ponds Road, Gilgai, came in with middle-of-the-road costs per square metre.
And while the home has all the mod cons, its owners will not recieve quarterly power or water bills - ever.
The off-grid home was designed to suit the site, to get the best solar orientation and natural ventilation, using the righ tmaterials to shrug off the need for air conditioning despite temperatures well below zero in winter and climbing to the high 30s in summer.
The only trench into the site was for the telephone line.
It is entirely self sufficient in its water supply and hot water is supplied through a gas boosted hybrid solar unit.
A stand-alone solar photovoltaic system puts the home entirely off grid with a back up battery providing five day’s autonomy.
Anecdotal evidence from the home owners indicated strong performance in terms of energy usage amd livability.
”The owners moved into the home in late January, on the cusp of a prolonged period of extreme heat and subsequent drought,” the award submission said.
”In spite of this, the home retains high comfort values, without the need for air conditioning.”
The concrete slab foundation of the home is a cupolex system made from recycled non-toxic polypropylene.
The system provide thermal heating capacity and uses less steel, leading to a lower impact on non-renewable resources. Stainless gutter guard and non flammable materials were used.
Michael said there was slightly more involved in running a smart home such as monitoring batteries but much of its efficiencies were behind the scenes.
