Open building solution controls Swedens largest passive house

In order to live up to extreme demands for low energy consumption, Goodtech decided to standardize on Beijer Electronics’ open solution with CODESYS-based hardware complemented by iX HMI software. They felt this was the future within building automation, and a highly sustainable solution for the end customer.
The new building lives up to rigorous standards for energy efficiency, reducing its ecological footprint.
