People are nowadays spending most part of their life time in rooms, be it working or leisure time. Therefore, the claim arises to design the indoor environment in a way that ensures health, thermal comfort and performance. Adequate target values must be formulated and constructional and technological solutions must be provided for this purpose. The pursuit of the correlations of effects requires research in rooms that is complex, time-consuming and expensive. This is why the test environment must be designed in a way allowing fast and easy variations of ambient conditions to investigate human reaction like perception, sensation, experience and behaviour.

Within the context of the research and development initiative High Performance Indoor Environment (HiPIE) this kind of test environment was created. On an area of approx. 45 square meters, which can be freely designed, the HiPIE laboratory allows the targeted conditioning of building physical boundary conditions of acoustics, lighting, indoor climate and air quality. A virtual acoustic environment can be created there for example by generating an almost optional room acoustic sound scenario by a multitude of sound sources by means of the so-called wave field synthesis. Moreover, a controllable daylight partition in front of the windows of the test room does not only provide a virtual view out of the window but also allows adequately defined investigations on the balance of daylight and lighting systems.

The example of office work demonstrates the enormous potential of the research and development initiative. Nearly every second workplace in Germany is an office workplace, the running costs of which amount to more than 80 percent of the labor cost. To improve the indoor climate, health, thermal comfort and performance of the employees significantly contributes to efficiency, and simultaneously provides sustainable satisfaction. This does not only apply to offices but also to rooms in educational institutions, hospitals and other buildings for which the HiPIE laboratory is best suited to carry out investigations.
