Sustainable neighbourhood Eco-Viikki

Helsinki

Detailed description of the Good Practice

Eco-Viikki was built between 1999 and 2004.The district is situated at about 8 km from Helsinki city centre, near an extensive area of open farmland encircling an important wetland nature reserve, The Viikki Science Park and Helsinki University’s Biocentre.
The Viikki housing area of 6400 m2 consists of apartment blocks and row houses for 2000 inhabitants and services. The mix of housing types is typical for Helsinki: approx. 50% of the homes are owner occupied,15% are rented, and the remaining homes are right-of-occupancy homes.
During the planning and construction of Eco-Viikki exceptionally strict ecological criteria were set by external consultants mostly concerning five main issues:
· Reduction of pollutants (CO2, sidewater, site debris caused by construction, domestic waste, eco-labels)
· Use of natural resources (reduce fossil fuels, multi-purpose use of space)
· Healthiness (indoor climate, moisture risk control, noise, the wind-free and sunny qualities of the site, alternative floor plans)
· Biodiversity (plant choices and habitat types, storm water)
· Nutrition (plants, soil)
Strict environmental controls have been regularly carried out during the construction phase. The City of Helsinki controls the evaluation process as a client and supervisor.
