The EU Parliament approved in April 2009 a recommendation that member states have to set intermediate goals for existing buildings as a fixed minimum percentage of buildings to be net zero energy by 2015 and 2020.
For the existing non-residential buildings, a dramatic reduction in primary energy consumption is crucial to achieve this goal. A few renovation projects have demonstrated that total primary energy consumption can be drastically reduced together with improvements of the indoor climate. However, most property owners are not even aware that such savings are possible, and they set energy targets that are too conservative. Buildings renovated to mediocre performance can be a lost opportunity for decades. It is therefore important that building owners are aware of such successes and set ambitious targets.
