Urriðaholtsskóli is a school that serves two educational levels, kindergarten and elementary school, and is for children aged 1 to 15 years. The school is located in the sustainable Urriðaholt neighbourhood, which has the BREEAM Community certification. The goal of the school building structure is to achieve BREEAM certification. The school building features two stories and a basement. It is constructed from reinforced concrete, is externally insulated, clad in aluminium, and the roof is covered with turf. The life cycle assessment was conducted as part of the BREEAM certification process. The assessment was performed over a 60-year lifetime for the following building components: Ground slab, plinths, floor slabs, flooring, ceiling, roof, exterior walls, interior walls, windows, columns, basement walls and retaining walls.
