When planning the computer company Lauer Systems?new administration and research building in Unterensingen, it was decided to vary the architecture from the surrounding industrial buildings with their uninteresting flat roofs. An ambitious landscape design with a lot of green was requested. As the foot print of the building was going to take up most of the development area, it was planned to provide intensive landscaping on the three lower roof levels. Only the upper roof was provided with an extensive landscape. The three intensive roof areas are landscaped to reflect the internal functions at each level, providing outdoor areas for the Casino and conference rooms, to hold company picnics and other events.Each of the four roofs of the Administration Building of Lauer Systeme GmbH supports a greenroof system. Two of the four greenroof levels are visible from above, providing pleasant views for employees. The two largest greenroofs measure 500m2, are located on the first and second floors and have contrasting styles. The first floor garden design is dominated by seven rigid geometric formations, while in contrast the second floor greenroof provides curvilinear paths through luxuriant plants leading to a centrally positioned summer house.
ZinCo International’s Floratec FS 100 build-up system was employed. The Floratec drainage boards were installed first, followed by the filter sheet laid onto the boards later. The drainage boards alone are strong enough to build on. The continuous layer of drainage over the entire roof allows unimpeded drainage beneath. The strip foundations indicate footpaths between the plant beds and terraced areas.The ZinCo System Build-Up:Landscaping with lawn, shrubs, bushes and treesSystem Substrate ?Roof Garden,? 200 – 700 mmFilter Sheet SFFloratec FS 100-elements, filled with ZincolitInsulation Protection Mat ISM 50Roof system with root resistant waterproofing
