From SINTEF research to flexible buildings: Thermal Box in Norwegian SciTech News
Norwegian SciTech News explores the research behind Cartesian's Thermal Box and the role thermal storage can play in managing buildings' heating and cooling demand.
By Cartesian

Making better use of existing heating and cooling equipment starts with timing. Thermal storage separates when heat or cold is produced from when a building needs it, helping systems respond to peaks in demand.
Making stored energy controllable
In a feature by Hege Tunstad, Norwegian SciTech News traces Cartesian's development from SINTEF research to commercial applications. The article explains two central elements: a heat exchanger designed for repeated phase changes and ultrasonic sensing that tracks the energy available inside the store.
Together, these developments turn phase change material into storage that can be monitored and controlled as part of a building's energy system.
From the laboratory to larger buildings
The feature follows the technology from a prototype installed at the ZEB laboratory in Trondheim in 2021 to the programme supplying 30 Thermal Box units for Amazon facilities in three European countries.
