The Sergelhuset project is located in central Stockholm and is one of the most visible buildings in Stockholm. The first building was built back in the 1960s. During project planning and construction, most architects proposed to demolish the entire building, but it was decided to leave the concrete structure. This decision has successfully avoided high CO2 emissions. The building has a renovated façade in which the original granite stone of the old building has been reused to decorate the façades.
The stone was delivered, processed, washed and placed into unitised curtain walls at KG Constructions factory. The street-level floors open with large glass sections, “eyes to the street” and gain a strong commercial touch. Much attention was paid to the environment and sustainability: The frame of the house was preserved and reused. The stone façade of the 1960s was removed, washed and rebuilt. Many measures have been taken to obtain LEED Platinum environmental certification, such as the evaluation of construction products in the selection of materials, the wise choice of energy and the use of rainwater to wash toilets. This contributed to the LEED Building of the Year award at the Swedish Green Building Awards 2020. The Sergelhuset LEED certificate has also recently been awarded the highest Platinum rating and a world-class rating.
“KG Constructions Group” is responsible for the design, project management, production, transportation and installation of 4 700 unitised and almost 1 000 m2 of stick curtain walls.
