Integrated building simulation: state-of-the-art

This paper outlines the current state-of-the-art in integrated building simulation. The ESP-r system is used as an example where integrated simulation is a core philosophy behind the development. The current state and future developments are documented with examples. The importance of the interoperability is discussed in the area of air flow, multi-dimensional conduction, lighting, CFD, and power flow modelling. It is argued that for building simulation to penetrate the profession in the near future, there is a need for appropriate training and professional technology transfer initiatives.
