Renovation with the goal of reducing energy consumption by 60%. Insulation not only contributes to energy efficiency but also reduces heating costs.
The starting point
Fogdetorp is a large housing cooperative in Södertälje, Sweden, with 378 apartments distributed in 9 buildings that were built between 1967 and 1968. From 2018 to 2021, an extensive renovation of the properties was carried out. The buildings’ ventilation was inadequate, and the leaky windows, facades and balconies had reached their technical lifespan. The goal of the renovation was to reduce energy consumption by 60%, reduce CO2 emissions and improve the living environment.
The work
The buildings were insulated with PAROC® stone wool, which not only contributes to energy efficiency but also reduces heating costs and improves living comfort. The facades were renovated using the SmartFront method with PAROC® Smartfront and PAROC® Fatio Plus.
Additional insulation was installed on the external walls of the buildings, which meant that no apartment space was lost and the residents' everyday life inside the apartments was minimally disturbed. New supply air ducts, connected to an FTX unit on the attic floor, were mounted in the inner insulation layer.
The outcome
The renovation was nominated for the Facade of the Year 2022 (Årets Fasad) prize in Sweden. The additional insulation provides housing with reduced energy consumption, CO2 emissions and heating costs. The added insulation also dampens outside noise and makes the indoor temperature more stable, as now it is less sensitive to sudden changes in the outdoor temperature.
