Roof greening system that has proven itself over decades:
Nature Roof system solution. Biodiversity, species protection and nature conservation


Greened roofs combine a variety of positive effects. Perhaps the most important and understandable argument in favour of green roofs is their role as an “ecological balance”. With its Nature Roof campaign and the Nature Roof system solution, Optigreen international AG presented a green roof structure over 20 years ago that displays greater ecological significance than frequently-used simple sedum roofs thanks to its biodiversity (species and structural diversity).

Innovative rainwater management: weather app controls drainage from green roof


Around 74 hectares of natural space is sealed off in Germany every day. These areas are disappearing from the natural water cycle over the long term. The drainage system is outdated and insufficient in almost every town and city. Investments and expansions in the existing system are very costly and are thus avoided. The more affordable solution is to restrict the discharge permitted into the overloaded drainage network. What’s more, flooding verification in accordance with DIN 1986-100 has increased in importance over recent years. The quantity of water produced should be verifiably retained on one’s own property without buildings becoming flooded.

Optigreen international AG has kept abreast of these developments and developed the flow control-type “retention roof” system solution in the versions “green roof” and “public roof”. This means there are now innovative solutions for setting a specified maximum discharge and to thus observe the restriction on discharge into the drainage system

Unique solar retention green roof in the Dutch city of Brunssum combines many advantages


The Sanforum center for health and diagnosis in the Dutch city of Brunssum, which was built mostly during the last year, contains several health and spa features. This modern complex contains everything related to health e.g. doctor's consulting offices, chemist's shop, ergo-, physio- and speech therapy.  It also offers ambulant primary care and subsequent secondary care. Additionally there are informative events, workshops and conferences related to health issues. Furthermore, there are plans for assisted living facilities. The objective of both owners and planners is to create a spa and health center for the region, that thoroughly covers every aspect of these topics. All this should be accomplished by means of a modern building which should be friendly towards visitors and patients, which should also be functional and appealing and blend harmonically into the green surrounding landscape.

There is often the talk of greening the complete outer surface (four walls and the roof) of a building and provide it with a “green shroud“.  This was done in Eupen, situated just over the border into Belgium, where the new Parliament building of the German Speaking Community is situated. The project was implemented in an exemplary manner over 635 square meters of roof and walls greening. Modern architecture combined with advanced building greening concepts have created an impressive estate inserted between the historic main building and the park.
