22·26 Kirchstrasse

Lustenau I Austria

Brief

The brief called for a new complex that would help densify the existing town centre – not as an isolated housing settlement, but as a public district with shops and a park. What’s more: The Kirchstrasse project uses the method 22·26 as a further statement on clever climate architecture.

This new development shows once again that a very dense use of the property and sufficient open space need not be a contradiction in terms.

Realisation

Our plan envisions four buildings on an approx. 4000 m2 site. The three- to five-storey buildings will include commercial space on the ground floor and a total of around 100 residential units, mainly 2, 3 and 4-room apartments. The complex’s underground car park offers both public and private parking spaces, further emphasising its connection to the town centre.

Density and scope, openness and privacy

The complex’s high density creates open space between the buildings that will be accessible to the public as a park and promenade, enhancing the town centre’s appeal. All apartments have a spacious balcony, giving residents a chance to enjoy private outdoor space as well.

Features

So far, most structures using the method 22·26 have been office buildings. Kirchstrasse is our first larger 22·26 housing project – and a statement on energy efficiency and sustainability in residential construction. Even without conventional air-conditioning technology, the buildings maintain year-round, comfortable temperatures between 22 and 26 degrees Celsius – all with consistently good air quality. The key? Solid construction, energy storage capacity, a well-balanced interplay of façade and window surfaces, and software-controlled – but also manually operable – ventilation openings. Heat generated by users, lighting and appliances are factored in as well.

Pioneer project for 22·26 residential buildings

Residential structures have a higher hot water demand than 22·26 office buildings. Efficiently meeting it requires warm water heated in boilers using air-to-water heat pumps, which will be powered with solar energy. The approach could constitute a guiding principle for future 22·26 residential buildings.
