In a quiet Kearneys Spring street, a 21st century energy efficient house is rising out of the ground.

Local builder Titanium Homes has been tasked with building Toowoomba’s first “Passive House”.

The German house design offers the highest standards of energy efficiency substantially reducing its ecological footprint.

Titanium Homes owner Nathan Peters has overseen the build and says that despite years of experience in the industry he is learning new things every day.

“I’ve always had an interest in the concept, and while it has been a challenging build in some aspects, it has been great to work with the designer to bring it to life,” Mr Peters said.

“They’re much more energy efficient than your standard home, and with the way things are going they might become more popular,” he said.

A “Passive House” conserves energy by strictly limiting heat transfer through sealing technology. The design also utilises highly insulated exterior walls, roof and floor slab. A ventilation system delivers superior air quality and an allergy-free environment.

Member for Toowoomba South David Janetzki noted the ground-breaking design technology and congratulated Titanium Homes on their construction of the house.

“It’s pleasing to see a well-respected local company that employs local people deliver such an innovative project,” Mr Janetzki said.

“It’s extraordinary that during a cold week like we’ve just had the temperature inside this house would not drop below 20 degrees,” he said.

The extra house features generally add between 10% to 15% to the total build cost.  However, the design provides for energy savings of up to 90% compared with standard existing buildings and over 75% compared with an average new construction.

The house is nearing completion and will be shortly on the market for prospective Toowoomba home buyers to inspect.
