Thatched Passive House Plus

Thatch-covered Enterprise Centre may be the world’s greenest building

Prefab thatch wall panels (built indoors during the off season) and materials palette which the Treehugger writer calls ‘almost edible’.

“John French, CEO of the university’s Adapt Low Carbon Group and project director, … was eager that the next generation of buildings at UEA should move away from high thermal mass and a dependence on carbon-intensive concrete, towards natural and locally sourced materials.”

“The building also features a wide array of other sustainable materials including recycled timber finishes, wood wool acoustic boards, spray-on cellulose, and wall coverings made from hemp, nettle fabric and reeds”

A 3D Printer that builds homes

Unlike earlier 3D printed houses which used plastic, this one uses clay.  Very cool!

The World’s Advanced Saving Project, or WASP, has just unveiled a giant 3D printer that – rather like a real wasp – can build a house out of the stuff.

The 3D printer, called BigDelta, works much like any other you may have seen – layering up a material into a pre-determined structure. The difference is that it stands 12 meters (40 feet) tall and claims to be the world’s biggest.

It was unveiled this weekend at the three-day “Reality of Dream” rally in Italy, where BigDelta was made. In a statement, WASP proposes that its technology could help meet the rising demand for housing, citing a UN calculation that over the next 15 years there will be an average daily demand for 100,000 new housing units.

It is thought the technology would be of most use in disaster or war zones, where the speed of production could help those who have become displaced. The use of natural materials could also benefit the environment by reducing cement – a major contributor to carbon dioxide emissions.

You can watch the journey of BigDelta from desktop prototype to field-dwelling giant here.

Straw Social housing in UK

Recent articles in the Guardian and other publications tells of strawbale “Council housing” in the UK. Council houses are a form of social housing. The local council builds the houses which are then offered at a subsidised rent to people who are unable to afford full rental values.
