27 Climate-friendly and energy-efficient construction with wood – Basic information and implementation
4.3.1 Reference property Hegianwandweg The ‹Hegianwandweg› housing project on the outskirts of Zurich is used to study the effects of different construction types on energy, ecology and comfort. This building complex, constructed with wood and other materials and technologies on behalf of the Zurich family home cooperative FGZ, has proven itself in its actual construction form, but could also easily be built using other methods, and is therefore an ideal reference building. The reference building studied consists of a solid basement and four or five residential floors in timber frame construction, which are arranged around a solid core with connecting areas and wet rooms (cf. figure 17). The intermediate floors are made of laminated timber with suspended ceilings and footfall-sound-insulated

floor surfacing. The exterior walls consist of wood frame elements with flexible facing formwork on the inside and rear-ventilated cladding on the outside. The room and party walls are light and non-load bearing. The buildings, completed in 2003, are certified to Minergie standards. In comparison with the more stringent requirements of ‹MuKEn 08› the reference building, with 111 MJ/m2a, falls just short of the current applicable limit of 107 MJ/m2a. Further information on this interesting building complex can be found in the Lignum ‹Holzbulletin› 73/2004 and in a supplement to the journal ‹Hochparterre› 10/2003.
