Smart Energy Metering System

In Multi-family apartment buildings and Housing associations owned Single-family houses, heat - and where relevant cooling - meters are used to identify how much energy has been consumed by each occupant. Registering the energy consumption allows fair and more accurate energy cost allocation. It also raises the awareness among the occupants to lower their consumption and by that increase the buildings’ energy efficiency and save on their energy costs.

Therefore every apartment can be equipped with an energy meter. These are so called ‘secondary side meters’. Danfoss offers high quality ultrasonic meters that can be mounted in the flow or return pipe. The meters offer a new level of installation and commissioning simplicity by using a special App. The meters can be readout fast and easy by combing the App with a hand-held wireless radio receiver. Occupants don’t need to be at home in order to register their energy consumption, a simple ‘walk by’ the meters is sufficient to register the data.  

Sometimes also primary side meters are used. They register the total amount of heating or cooling energy provided to, or generated in, the apartment building.

In commercial buildings with multiple occupants the use of heat and cool meters is increasingly popular. They are used for sub-metering to determine the amount of energy (heating / cooling or domestic hot water) is consumed by each occupant. Registering the energy consumption allows fair and more accurate energy cost allocation. It also raises the awareness among the occupants to lower their consumption and by that increase the buildings’ energy efficiency and save on their energy costs.

Primary side meters register the total amount of heating or cooling energy provided to, or generated in, the building. Secondary side meters register the amount of energy consumed per occupant, floor or room in the building. The exact possibilities depend on the design of the HVAC system.
