Outdoor testing under realistic transient boundary conditions ultimately delivers the most convincing results. Further advantages are gained when outdoor tests are combined with simulations, which can then be validated while keeping outdoor testing costs down to reasonable levels at the same time. Fraunhofer IBP’s site in Holzkirchen is home to the world’s largest full-scale outdoor testing ground for building structures and components, building materials and building system components. The local climate is characterized by extremes of weather that make it perfectly suited to this task, including strong sunshine in summer, cold winters and driving rain.

One large and several small meteorological stations are situated on the outdoor testing ground and in the immediate vicinity. A number of these stations have continuously recorded all key climate parameters since the 1980s. They provide the data needed for a precise analysis of weather conditions and their local dependencies (microclimate analyses). The collected data also serve to establish the boundary conditions for hygrothermal and energy simulations and to facilitate more precise interpretation of outdoor test results.

 

 

Project

Weather watching for science

Researchers at the Fraunhofer Institute for Building Physics IBP already have 60 years of relevant experience in dealing with the topic of weather and tracking its development.

 

Project

Microbial growth on insulated façades

For manufacturers of composite thermal insulation systems, microbial growth on thermally insulated façades still poses a problem. Approaches to solving the problem using building physics are all based on the idea of reducing moisture on the surface of the façade.

 

Project

Surface moisture

Insulation materials reduce the amount of heat that external components transfer away from the building’s interior. In terms of building physics, this increases the probability that condensation might form on the outer surface of the façade due to the cooling effect of long-wave radiation of heat during the night.

 

Project

Flexible roof pitch

The Fraunhofer IBP has a flexible roof testing facility designed specifically for pitched roofs. Adjustments to the roof incline can be made in step-wise fashion, and various roof setups can be installed next to each other and then oriented as desired to the north or south.
