Green roofs not only improve the visual appearance of cities and buildings but also possess a number of properties that have an overall positive impact on the environment, on the quality of the air and on the quality of life in densely populated areas. For instance, the planted areas lead to a reduction in urban heat islands, retain rainwater and delay its runoff thanks to their good water storage properties. At the same time, green roofs have a thermal and energy-saving effect on buildings which, among other things, noticeably improves thermal insulation. This wide range of benefits has also been recognized by districts and local councils. They promote and call for greened roofs in equal measure.
We assist green roofing companies, local councils, planners and contractors in constructing and maintaining durable green roofs with a positive effect on the climate.
Take advantage of our experienced expert team to safely plan environmentally-friendly and durable green roofs for all constructions and climatic zones!
On our outdoor testing site, systems or individual products are exposed to realistic weather conditions. Tests focus on the release of substances, water retention capacity, sensory measurements, and other aspects. Test set-ups and parameters can be adapted to suit the case in question. The acquired data can also be used to model system structures in simulation programs and to validate the resulting digital twin. A weather station located on the test site is used to record all relevant weather data during the test period.
Hygrothermal simulation allows the effects of greening systems to be calculated quickly and easily with a wide range of general constraints. Depending on the objective and chosen software, the durability of the roof structure as well as the impact of the green roof on the indoor climate, on energy consumption and also on the urban climate can be evaluated.
