Kiruna's new town center opened in autumn 2022. Many residents now describe the area as a cold trap. Research from Gothenburg University confirms their experience. The study shows temperatures dropped significantly in the new location.
The problem stems from the center's position in a valley depression. Cold air collects there during winter months. City planners failed to consider urban climate patterns when selecting the site.
Building placement and street grids also contribute to the issue. The new streets form a rigid grid pattern. Tall buildings line narrow streets that block low winter sun.
Jennie Sjöholm, a built heritage expert at Gothenburg University, explained the situation. She said decision makers did not optimize the urban climate when planning the city's layout.
Sjöholm noted the new Kiruna remains unfinished. She suggested compensating through strategic tree planting and street design improvements.
The northern Swedish city of Kiruna is undergoing Europe's largest urban relocation. Mining subsidence forced the move of the entire city center. This climate issue adds another challenge to the complex project. Urban planners worldwide can learn from Kiruna's experience with microclimate considerations.
