Beautiful, big and chic and yet electricity and heating in this house cost only two euros a year

Building ecologically without spending a lot of money is an art. This house consumes hardly any energy and water, looks great and is quite affordable. A trick makes it possible.

What we call an energy-saving passive house is called a 10-star house in Australia. It means the same thing: The building takes no energy from outside for heating and cooling – particularly important in Australia. The architectural firm The Sociable Weaver from Melbourne has built the first house with a rating of 10 stars in Australia. What’s special about it is that it looks stunning and isn’t all that expensive. 160 square meters of living space cost around 330,000 euros – including essential elements of the interior design.

Virtually waste-free

Built in a jiffy with Scaffold hire: Not only does the house consume no energy, beyond that it produced hardly any waste. Nat Woods of Sociable Weaver calls it a sustainability package.

During construction, only three bags of trash ended up in the landfill. That worked out because packaging was reduced and local building materials were used. Even the leftover sections of building materials were recycled. Most importantly, the house remained affordable because it wasn’t designed as a high-tech home. “We chose processes and technologies that were available in the market and that our clients could afford. We didn’t want to design a house that required elaborate technology or complicated processes.”

Energy consumption In this house, electricity and heating cost only two euros a year

No elaborate technology

On the outside, the house is clad in hardwood panels; inside, the floor of polished fine concrete adds contemporary chic. The butterfly-shaped roof is exciting. The angle of this shape optimizes solar gain to heat the building, and solar panels on the roof also benefit. High ceilings facilitate air circulation. Features include: 5 kW solar panels on the roof, heat pump for water heating, 10,000 liters of rainwater storage, double glazing, and LED lighting. With normal energy consumption, residents would have to pay about two euros a year for electricity and heating energy.

This is because most of the time the house heats itself passively, that is, without the need for a heating system to supply additional energy. “We used a new insulation technology called “Bio-Phase Change Material” that is installed in walls and ceilings to trap and release heat. Even on a cold winter day, the house is still warm inside without the need for additional heating.”

Of course, the house was outfitted with organic materials – starting with the wooden furniture and extending to the bamboo toothbrushes in the bathroom.
