Description | In October 2009 the construction work of the world largest Passive House settlement with 1.700 flat at 100.000 m² has started. Within a tender the City administration of Vienna has stated the Passive House standard as a precondition for building on the 20 ha former railway area. 7 property developer have submitted their concepts for building story buildings, showing a Heating energy demand between 7 and 15 kWh/m².a. The residual heat energy demand will be covered by district heating and the settlement is very close to an underground station. In the year 2010 in Austrians capital Vienna 20-30% off all new houses will already be built in Passive House standard.
Lessons learnt | A propriate instrument to achieve high energy efficient building standards at new building is to constitute clear preconditions (e.g. obligatory Passive House standard) for the builing site.
