Smart ventilation in high-rise block cut the costs
86 apartments – 86 different needs
Kajalen had to be built in an energy-efficient way to meet rigorous energy saving requirements. It was therefore necessary to provide an end-to-end solution for demand-controlled air flows that was not only energy-efficient but also simple to monitor, maintain and service. Ventilation management and control was a particularly critical factor. The considerable amount of time and administration that it would take for one technician to check the air inside the 86 apartments was something to be avoided.
Tremendous savings potential
In a building with lots of apartments where occupancy varies, there is huge potential for making savings. As much as 80% of fan electricity and 40% of heating/cooling energy can be saved with demand-controlled ventilation compared with a system that maintains a constant air flow. The turnkey system that property owner Kalmarhem had installed not only resulted in reduced energy costs but lower management costs too.
