K1 – Karlbergs Strand






Stockholm, Sweden

Project Type

1. Office Buildings

In the autumn of 2015, Fastighetsvärlden was able to reveal that JM planned to move its head office from Frösunda to Karlberg.
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 opportunity to develop sustainable, modern office premises with lake views in two directions and with recreation areas and city pulse around the corner, just a stone's throw from the subway.

Our Contribution:

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, shading devices, properly model the atrium with Dynamic Thermal Modelling tool, and provide control system for accurately predicting the shading use.


Proper Atrium modelling

A main reason of 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 an 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 center of the Atrium, we were assigned to provide a more accurate assessment using an in-house DTM software tool that can capture such phenomena.
