A flagship project by Implenia for the 2000-Watt Society. The housing estate meets the latest requirements of the SIA path towards energy efficiency and comprises 65 terraced houses and apartments.
schorenstadt is Implenia’s flagship project for the 2000-Watt Society and has been developed in partnership with renowned Basel architects Burckhardt+Partner AG and other specialists.
Depending on the type of building, a variety of modern timber construction methods (hybrid construction with concrete ceilings and columns; mixed construction with concrete-covered laminated timber ceilings; wood-panel construction) are being used.
The project is divided into three rows of buildings, each containing different types of terraced housing, as well as apartment buildings. All of the terraced houses have a basement, a ground floor and a first floor, as well as an attic level with a large roof terrace. The offset arrangement of these terraces creates an additional private space outdoors. The interior spaces boast an intelligent layout and offer a great deal of design freedom. The rooms are also flooded with daylight, giving them a light, airy feel.
Apart from the Minergie-P-Eco standard, the 2000-Watt Society’s quantitative targets were also implemented. To do this, the mobility energy resulting from the property’s location is taken into account in addition to the energy required for its operation. The third component to be considered is the energy used to produce and dispose of the building materials. These three components are defined in the SIA path towards energy efficiency with guidelines and target values, which were thus applied to the property.
Aside from the energy consumed, the greenhouse gas emissions generated by the construction, operation and mobility associated with the building from the second key measurement for the SIA path towards energy efficiency. As the mobility energy is already firmly established purely as a result of the location, the focus therefore had to lie on reducing operating energy in the first instance. To do this, it was decided, among other things, that the heat required for heating and hot water was to be provided entirely by the district heating supplied by a wood-fired power station owned by Industrielle Werke Basel IWB. This measure ensures that the greenhouse gas emissions generated during operation can be kept low.
Secondly, low energy consumption also had to be considered when selecting building materials for the construction work. This is why the majority of the complex was built using timber construction methods. Unlike other building materials such as concrete, timber has the advantage of requiring very little energy to obtain the finished building product.
Thanks to these measures, the complex managed to meet the requirements of the SIA path towards energy efficiency. This has also been demonstrated after the first two years of operation. schorenstadt thus shows that environmentally friendly construction does not have to mean compromising on comfort or aesthetics. On the contrary, these requirements can go hand in hand.
