Boverket

Along the waterfront in Karlskrona, construction has begun on Boverket's new headquarters, designed by Sandell Sandberg architects. The project is commissioned by the property company Vacse, with Skanska leading the construction work. Right from the procurement stage, the goal was to certify the property according to several strict environmental standards, including NollC02, Well Platinum, BREEAM SE EXCELLENT, and Energy Class A.

During an early climate analysis, it was observed that the largest carbon dioxide emissions came from piling, the structure, and the extensive façade glass, accounting for 85 percent of emissions. To achieve the goals, innovative solutions were required – where one of the keys to success was found locally.

Initially, the plan was to use a double shell façade, but due to significant carbon dioxide emissions, a rethink was necessary. Instead, the double façade with its integrated blinds was replaced with standard single façade with dynamic glass from ChromoGenics, reducing the amount of glass and steel used and resulting in a thinner floor slab.

The product, ConverLight, is an advanced technology where an electrochromic foil is laminated into the glass to regulate the intensity of sunlight and heat penetration into buildings. When the sun shines, the control system darkens the glass, significantly reducing the need for air conditioning. Similarly, solar heat can be allowed in during the winter to reduce energy consumption and heating costs. This solution also provides a natural daylight effect and unobstructed views – offering several positive health benefits for the over 250 people who will work in the building.
