Exterior view of the new IEQ lab of the Hermann Rietschel Institute (HRI) at TU Berlin.

Interior view of the new IEQ lab: 54 individually controllable surface modules on the walls and ceiling can be heated or cooled. Electric heating textiles and water-based capillary tube mats enable rapid temperature changes.

The laboratory’s distinctive feature lies in the close coupling of virtual reality and physically generated spatial conditions. For example, through a VR headset, test subjects see an office with specific windows, lighting conditions, or spatial geometries.

Know How, Institute

New IEQ Lab at TU Berlin’s Hermann Rietschel Institute combines a climate chamber and virtual reality to investigate how energy efficiency, health and comfort can be brought together in buildings

Experience spaces before they are built

How warm should a room be, how much light do we need, and when do we perceive the air as pleasant? In the new IEQ Lab at the Hermann-Rietschel Institute (HRI) of TU Berlin, such questions can be investigated under precisely controlled yet realistic conditions. To this end, the laboratory combines a…
