Today, buildings are responsible for 40 percent of the energy consumption and 36 percent of the CO2 emissions in the EU. Our mission at Bemsiq is to accelerate the journey towards smart and climate neutral buildings by offering leading sensor, control and energy connectivity technology on the global market.

The accelerating pace of global urbanization and the increasing number of megacities have led to several new and increasing challenges for cities, putting pressure on the ecosystem and surrounding functions.

At the same time, technology development continues to advance faster than ever, creating new possibilities to tackle the challenges of the world. Smart cities try to adopt these technologies in order to improve life and services of its inhabitants and visitors. Building automation and metering are key elements in making the cities and the buildings of the future smart.

Several technologies are developing rapidly: traditional building automation systems are digitalized at an accelerated pace, and wireless technologies enable easy installation of a large number of communicating sensors and meters. This will lead to a rapid increase of data availability; a treasure trove for advanced analytics to support energy management.

In the long run, Bemsiq firmly believes that digitalized and energy efficient buildings will become a future standard and our ambition is to take an active part in making this a reality.


Bemsiq is a group of innovative and fast-growing companies providing products in building automation and metering. The group is operating in the Nordics, Europe and the Middle East with the ambition to build the most comprehensive portfolio of products within the smart buildings market.

The companies operate both independently and together as a group. In a truly smart building, you will most probably find products from several of the companies within Bemsiq.

Our primary customer segment is system integrators, who use our products to design energy and cost-efficient solutions for their customers. We also work with utilities and energy service companies, where we deliver solutions for metering.

Bemsiq is one of six wholly-owned business areas within Investment AB Latour, a Swedish mixed investment company quoted on the Nasdaq OMX Stockholm Large Cap list.


Buildings are responsible for 40% of energy consumption and 36% of the CO2 emissions in the EU. The ability to reduce environmental impact of buildings will be key in order to reach set-up climate targets, in the EU and globally.

The products developed and sold by the companies in the Bemsiq Group are used in various building applications with the mission to accelerate the journey towards smart and climate neutral buildings; hence sustainability is integrated in our fundamental business model.
