EKO2 is a sustainable housing project located in Kristineberg, west Stockholm, on the island of Kungsholmen. The area is undergoing rapid development, and a new and exciting urban quarter is emerging.
From the start, the project has focused on reducing CO² emissions and on integrating this thinking into the architecture. The name of the project itself relates to the Swedish word for ecology (ekologi) and CO2.
EKO2 consists of two housing rows located around an attractive green courtyard area. The entire area is protected by a large glass wall, providing a noise baffle for the development, which borders three of Stockholm's major traffic systems. The glass wall includes the development's common building, which functions as a window towards the surrounding world. The glass wall is also equipped with solar panels, which contribute to the common building's energy supply. A meter showing EKO²'s current energy consumption lights up and helps to raise the awareness of Stockholmers in relation to sustainable construction.
The energy consumption of EKO2 is half that of the existing housing stock. This energy saving is achieved through double-insulation of the exterior walls, highly-insulating triple-glazed windows, and heat recovery systems in the apartments.
EKO2 contains 225 apartments ranging from 45 to 110 m² in size, divided between two-room apartments (8.5%), three-room apartments (78%), and four-room apartments (13.5%).
