The project has a special focus on environmentally appropriate and lasting solutions. Through the requirements for maximum energy given by tenants to build projects that meet the minimum grade B. Early in the project process it was decided to classify projects in BREEAM Eng. We work constantly to ensure that buildings achieve BREEAM Nor Excellent. The requirement for Excellent 70 points. The result is 76.5. Core factors for innovative and environmentally efficient design for the building is : compact building volume ( crucial for low energy ) , far fewer parking spaces than what BREEAM implies, conditions for cyclists with an indoor bicycle parking and associated dressing room and shower facilities , facilitating active use of public transport , green wall ( contribution to indoor environment ) , joint use of bicycle and fitness equipment for NSB and Union , selection of resistant exterior material ( stone and aluminum) , space -saving plan in general floors ( free seating).
