K1 Karlbergs Strand is an office property of just over 20,000 sqm. The property, which will be environmentally certified according to LEED Platinum, will house both JM's new head office and space for external tenants.

The collaboration with Solna Stad and Wingårdhs has contributed to the development of sustainable, modern office premises with lake views in two directions. The office spaces are complemented by recreation areas and city pulse, all conveniently located just a stone's throw from the subway.

Inform Design’s work includes setting performance and quality targets, developing elaborated methods and informing the Architectural design with robust solutions. Our role was to advise on TGU build-ups and shading devices, properly model the atrium with the Dynamic Thermal Modelling tool, and provide a control system for accurately predicting the shading use.

Proper Atrium modelling

The main reason for Inform Design’s involvement was to assist JM with properly modelling the Atrium using a Dynamic Thermal Modelling (DTM) software tool that can properly account for the temperature stratification in the space, as well as the impact of bi-directional flows on the temperature stratification. The aim was to suggest a skylight with maximum daylight benefits while avoiding overheating.

As a one-node model (not accounting for the temperature stratification in the space - well-mixed space) would provide a temperature that corresponds to the vertical and horizontal centre of the Atrium, we were assigned to provide a more accurate assessment using an in-house DTM software tool that can capture such phenomena.
