Dach zielony w Centrum Demonstracyjnym Odnawialnych Źródeł Energii
Short description of the intervention
The NBS is a 200 m² green roof created as a complementary element to the concept of a low-emission building of the Demonstration Centre of Renewable Energy Sources at the School of Mechanical Engineering No. 2 in Bydgoszcz. The roof serves as a recreational area for students and visitors, provides thermal insulation for the building, increases biodiversity and improves the image of the construction [1].

Promotion of naturalistic styles of landscape design for urban development
Increased green space area
Reduced biodiversity loss
Description of environmental benefits
The NBS consists of a 200 square meter big green roof which is a as a complementary element to the concept of a low-emission building. The green elements provide thermal insulation for the building and reduce the effects of the heat island. The vegetation layer of the semi-intensive rooftop partially restores the biodiversity lost in urban processes [1].
