On the border between Kölängen, a small-scale residential area with one-family houses and the agricultural land, a preschool for 160 children in 8 groups is built in two levels. The building is compact, with external stairwells and a well-lit lantern which brings daylight into the inner parts of the building. The exterior of the building is dominated by wood, just like its surroundings. The facade will eventually graze and melt into the surrounding groves. The outdoor areas have an educational and playful design including spaces for farming, water play, open fields, forest and historic remains. The outdoor spaces interact with the indoor environment with direct connection to various studios and spaces for nature-oriented experiments. This is one of several examples of how the school offers an indoor and outdoor environment where the design integrates with the pedagogic purposes and educators can help the children to a greater understanding of the nature and environmental issues in a playful way. Inside the building, the departments are divided by a middle part – the food atelier, the square and the upper studio. These shape the heart of the building and the hub of communication between the 8 departments, both on and between the two levels. The linear space is the core of the building with the generous and playfully designed staircase that brings the food atelier, light intake and communication together. The Kindergarten is designed to be certified as a passive house, which means 75% lower energy consumption than ordinary kindergartens. During the design phase, great consideration has been given to optimizing the indoor climate to create a pleasant environment, for both children and adults, all year round. Window placement and propagation has been carefully studied and is adapted to daylight needs, where sun shading contributes to comfort in rooms exposed to the sun. The roof is provided with solar cells, furthermore the climate shell is made of high-quality components and uninterrupted insulation, resulting in minimal thermal losses. The ventilation system is designed to provide both fresh air and low energy loss.
