The choice of the building geometry is often one of the first determinations during comparison studies of energy performance levels over Europe, but also during other European calculation studies. With this in mind, one of the subtasks of ASIEPI has been to gather a set of reference buildings. The aim of the set of reference buildings is to give an idea of typical houses build in Europe. When we make calculations on European level, we often extrapolate the results of one house, without the realization that houses in Finland might look totally different from houses in Spain. Of course it is not possible to determine one typical house for a whole country. But with this report a handle is given for information on the variety of typical houses in Europe.
