Conversion of an attic of a typical building from the period about 1900 to a passive attic with photovoltaic system and renovation of the existing building equipment. The aim is to keep the additional construction costs under 10 %, to avoid overheating in summer and to make possible a reproduction for the large amount of buildings from the same period.
In course of the monitoring project the effectiveness of the energy-technical system was checked on the basis of running measuring data. The data were evaluated and, if required, the arrangements and settings of the control system were adapted. Main result is that the energy balance could have been improved explicitly whilst the monitoring process.
The demonstration project "Technology centre aspern IQ" showed that the energy required for space conditioning (heating, cooling, ventilation, lighting, hot water) can be covered from domestic energy production.
