The Värta Terminal is the first commercial building in the green-profile Stockholm Royal Seaport area to be Miljöbyggnad Gold environmentally certified. The terminal, with Stockholm’s largest roof terrace, welcomes both vessel services and the general public.

The Värta Terminal is part of the ambitious environmental profile Stockholm Royal Seaport development. Miljöbyggnad Gold certification has been an environmental target throughout the entire construction process and the environmental requirements for this have been monitored during the project planning, procurement of subcontractors and production phases.

“We are very pleased that the Värta Terminal fulfils the high environmental requirements for Gold certification. The entire Värtahamnen port has become a modern, green port with many smart green solutions,” says Stefan Hansson, Chair of the Board at Ports of Stockholm.

The design of the Värta Terminal has been thoroughly planned and the energy use is 40 percent lower than for comparable buildings. All choice of materials and material components has been reviewed and documented using the SundaHus material assessment system.

“The Värta Terminal is open to the general public. Everyone is welcome to visit the city’s largest roof terrace with its attractive art installations, vast green spaces, photovoltaic cells and restaurant with outdoor tables,” says Karin Brofelth, Property Director at Ports of Stockholm.

Sweden Green Building Council Miljöbyggnad certification is the most prevalently used certification system for buildings in Sweden and is proof of important qualities with regard to energy, indoor climate and materials. A building can receive Bronze, Silver or Gold grade certification, with Gold being the highest and most challenging level to achieve. Over two years the terminal building will be verified according to the Gold certification, which means that approved actions will be compared with the execution of these actions in the completed building.

Examples of green facts about the Värtahamnen port:

  • The Värta Terminal and Customs building are heated and cooled by 62 geothermal energy shafts under the terminal. Most of the heating and cooling needs of the building are fulfilled using stored energy.
  • The roof of the terminal houses a 400 m2 photovoltaic system with high-performance panels that contribute electricity for use in the building.
  • The terminal has three green roof terraces with sedum plants and flowers from the archipelago. The green roofs isolate the building and retard rainwater run-off into surface water drainage systems.
  • Under the port esplanade there is a surface water drainage system that has been designed to cope with large volumes of rainwater and to purify contaminants out from the surface water.

Some of the more than one hundred environmental requirements during the project:

  • The majority of building materials have been prefabricated and delivered by ship, which has reduced waste and reduced emissions. At least 6 700 tonnes of carbon dioxide have been saved in comparison to delivering the materials using overland transport.
  • All waste has been sorted at source during production and only 0.3 percent has been sent to landfill.
  • Noise-reduction measures were using during the piling processes.
  • Vehicles and construction machinery had high emission requirements.
  • All construction electricity was supplied from renewable sources.
