Detailed description

Energy Efficiency

The usage of automated functions already save energy in every installation. Especially the usage of KNX has a lot of potential for further energy savings, which can contribute to a better environmental footprint. Be extending KNX to more functions and applications, energy savings of up to 60% can be realised. Thanks to the flexibility of KNX, these functions can easily be implemented in this installation

Innovation

Smart homes and buildings are always an upgrade in comparison to a conventional installation. Not only automated functions and a higher level of comfort contribute to a higher living standard, but also the possibility to be ready for coming innovations. Thanks to the usage of KNX, the door has been opened to integrate new innovative solutions, using the worldwide STANDARD for home and building control.

Ease of Use

By integrating KNX, we automatically experience a higher energy efficiency and comfort. Furthermore, by the possibility to use further devices, in order to make the usage of the project easier, we can look at further opportunity to even make the whole installation easier in usage.

Customer's description

The building has screens which are driven by a weather station. The weather station measures the radiation of the sun, wind, rain, brightness and the position of the sun based on GPS localization. The following actions are taken based on the temperature measured in the different zones of the building: - position of the screens is adjusted based on the parameters measured by the weather station - the floor and wall circuits are set for heating or cooling Overview of the submetering: - KNX P1 Gateway linked with the Smart Meter - temperature sensors on Heat Pump tubes (departure, return, source in, source out, ...) - calori meters (M-Bus) - real-time price of electricity via IoT technology The CEMS is placed in the cloud and stores an energy profile which has been created in cooperation with the customer The customer is able to adapt the energy profile parameters via visualisation locally or via the Internet (VPN). The CEMS is EN50491-12-2 compliant.
