In this contribution, we describe an ongoing recent
research effort involving the performance
assessment of a number of buildings by the
Austrian architect Konrad Frey, a pioneer of
energy-efficient architecture. A number of his
buildings, planned in the 1970ies, adapted the
principles of modern solar houses. A number of his
key projects are the subject of an ongoing
nationally funded research project. Thereby we
deploy building simulation to assess the energy
performance of one of his buildings (Kindergarten
Pachern, located in Hart, close to Graz, Styria,
completed in 1997). Moreover, the building was
subjected to detailed performance monitoring. This
building implements two design strategies: On the
one hand, the building is optimized for solar gains,
on the other hand it is embedded in the local
landscape´s morphology, using the benefits of
decreased transmission losses via ground-adjacent
building components. The building contains
standard facilities for kindergarten usage (three
group rooms, a gym, a kitchen, and sanitary
facilities). The intensive monitoring phase started
in summer of 2016. The monitored data is expected
to support the documentation of the building's
actual performance. Moreover, a simulation model
of the current state of the building will be
calibrated via the collected data. Based on this
calibrated model, previous states of the building
(subtracting later adaptions) can be simulated. We
thus can virtually reconstruct the building's
originally intended state and assess its
performance.
