Snowy Start, Blooming Finish for BMW Roof

At BMW’s new service center in Brno, a green roof was installed in midwinter without issue. The pre-grown Sedum mats endured the cold easily and, by summer, had transformed the roof into a lush, thriving layer of greenery in full bloom.

Multifunctional Surface

Every component of the roof plays a role. Rainwater is buffered, and nature is afforded space to flourish.

Climate adaptive design

The roof stores water during heavy rainfall and helps cool the surroundings during summer heat.

Biodiversity in the Built Environment

A diverse planting plan attracts pollinators, birds, and native insects. This turns the roof into a thriving ecosystem.

This green roof at the new BMW service center in Brno, Czech Republic, received a snowy beginning. The installation of the Sempergreen vegetation blankets occurred in the middle of winter (view the installation video below). However, this did not pose a problem for the quality of the plants. Because the Sedum mats are pre-grown, they can withstand the most extreme weather conditions. This is also evident from the photos and video of the following summer; the green roof is vibrantly green and grows and flowers abundantly.

Green roof installation in just 7 days

Installation of the 15,460 sq ft measuring green roof only took 7 days. Flat roofs are ideal for applying a green roof. The system structure for a flat, water-retaining green roof consists of a drainage layer with filter fleece, extensive roof garden substrate, and a vegetation blanket. Because the Sedum blankets are pre-grown, they are very easy to roll out, resulting in an immediate green result. The Sedum-mix blankets are planted with six to eight different types of Sedum and always boast at least 95% coverage on delivery.
