The Group implements international construction standards, including the preeminent standard for green building – LEED, which concerns the design, construction, and operation of environmentally-friendly buildings. In the management and operation of the centers, a broad variety of aspects are addressed such as separating waste, encouraging the use of compostable cutlery for serving food, creating parking infrastructure for electric cars, and more.
