Zusammenfassung
The building sector, accounting for roughly one third of total energy use in OECD countries, provides
huge and well-known potentials for energy savings which may be reached technically by
highly efficient insulation systems and HVAC systems. Assessing and optimizing the energy performance
in practice, however, needs a holistic approach covering the entire life cycle and focusing
on the interactions within the building and between its natural and urban environments. An integral
planning process requires information technology support based above all on the building
information model (BIM) and building performance simulation models.
This paper describes a new technology for verifying the performance of existing buildings by continued
design simulation in the use phase. Infrared thermography localized in six degrees of freedom
with concurrent numerical simulation is proposed for parameter calibration. In this way, the
model keeps track of the current building condition. Forward simulation and inverse parameter estimation
together provide for the quantitative interpretation of thermal images which is lacking in
building thermography today. Preliminary simulation examples will motivate the approach
