Tall, wooden, and sustainable
Edgetech’s Super Spacer has helped make one of the world’s tallest wooden buildings a beacon of energy efficiency, the company has announced.
HoHo Wien, located in Vienna’s 22nd district, is an 82m, 24-storey structure, designed to offer a visually distinctive and outstandingly sustainable space for hotels, restaurants, offices, apartments and more.
The building’s 1,100 triple-glazed units all incorporate Edgetech’s Super Spacer T-Spacer, allowing them to achieve U-values of just 0.5W/m2K, and helping the building save 2,800 tonnes in carbon emissions compared to a more conventional structure of the same size.
The building itself is a wood-concrete hybrid construction. The interior consists of a solid reinforced concrete core containing staircases, elevators and supply shafts, and prefabricated solid wood structures are arranged around it. The wall and ceiling elements made of spruce wood remain unclad to retain their natural character.
Its exceptional environmental performance has seen the project receive two prestigious accolades: a gold LEED certification; and a gold award from the Austrian Sustainable Building Council.
“We were delighted to be involved in such a fantastic, forward-thinking project,” Edgetech’s managing director Chris Alderson said.
“Pair Super Spacer’s exceptional energy efficiency with an ingeniously designed, sustainably constructed landmark like HoHo Wien, and you’ve got a template for the architecture of the future.”
