LEED Platinum

LEED is one of the world’s leading systems for environmental certification of buildings. Based on the number of points a building project achieves, one of four LEED levels is attained: Certified, Silver, Gold and Platinum.

For the Mästaren block, our goal is to achieve the highest possible standard: Platinum. If we succeed, this will be the highest level attained in the Nordic region. The following is a list of some of the choices we made to achieve the Platinum standard.

• The building is heated with district heating.
• Solar panels were installed on the building.
• Water-efficient mixer taps and toilets were used throughout.
• Significant emphasis was placed on the indoor climate, including increased air flow.
• Low-emission materials were used.
• All workplaces are exposed to daylight and have an outside view.
• Green roofs were installed.
• Measures were taken to reduce energy consumption.
• Locally produced materials were chosen.


The Mästaren block will also be certified in accordance with the GreenBuilding system, which aims to enhance the efficiency of energy consumption in premises. To be approved as a GreenBuilding, the energy requirement of the building must be at least 25 percent lower than the national standard.
