Energy transition in existing buildings achieved through cost-effective collaborative solution
25 September 2024
Efficient and cost-effective solutions are required to reduce energy costs in small and medium-sized buildings.
The European Energy Performance of Buildings Directive (EPBD) promotes the use of renewable energies in the building sector and the initiation of an energy transition to strengthen climate protection.
By combining its products with EnOcean technology, WAGO now provides a wide range of sensor data for existing building management systems. The solution in the 868MHz radio range forms the basis for reliable data transmission, and is optimised for building automation, even with very high sensor density.
Energy costs in small and medium-sized buildings must be reduced
According to the EPBD, the use of fossil fuels in buildings should be phased out by 2045 at the latest. "That sounds like a long time to the outsider, but it's not for owners and landlords of small- and medium-sized buildings. Here in particular, reducing energy costs through automation requires efficient and cost-effective solutions," says Wolfgang Arndt, Senior Territory Manager, Electrical Products Germany at Honeywell PEHA.
It is necessary to integrate a wide variety of sensor data into existing building management systems and ensure data transfer. At Light & Building 2024, Honeywell PEHA and its partner WAGO presented an innovative solution that uses proven EnOcean technology, and enables the flexible use of various formats such as BacNet Secure, MQTT or Cloud.
Universal solution with integration into an existing building ecosystem
"I am delighted that three market-leading partners have developed a powerful solution. After almost a year of intensive collaboration and development, the customer-oriented complete package can now be offered on the market," says Wolfgang Arndt. Thanks to the combination of WAGO and Honeywell PEHA products and their connectivity, a wide variety of sensor data can be provided for existing building management systems based on secure EnOcean technology.
In addition, the variety of PEHA field device products now allows a wide range of sensor data to be transported to the WAGO Compact Controller via the PEHA gateway. In this way, up to 16 gateways/antennas can be connected in parallel in a standard protocol (RS485) and the use of antennas and repeaters is no longer necessary.
The antennas work bidirectionally and there is also a clear assignment of the various field devices to the antennas. "Thanks to the existing EnOcean library in the Compact Controller, the customer can now create their project on a CODESYS basis as required and, if necessary, even have a self-sufficient solution, thanks to the integrated web server. However, integration into an existing building management system is essential in terms of efficiency," explains Holger Beland, Senior Area Sales Manager Industry at WAGO.
With the solution approach from WAGO, Honeywell PEHA and EnOcean, data from the Compact Controller can be integrated into the building automation system using various connection options. Regardless of whether Modbus, BacNet Secure, MQTT or Cloud is used, the operator can decide on site which field level the data flows into in their building automation system. This does not force the operator to make a premature decision, and the operator remains flexible until integration.
Ensuring compliance with all EPBD requirements guarantees added value for operators
"Another advantage for the operator is the fact that the EnOcean wireless technology can be installed during ongoing operation. It is also maintenance-free, battery-free and environmentally-friendly," emphasises Holger Beland. The efficient and cost-effective solution, which installers can also obtain from specialist dealers, makes it easy to implement the requirements of the EPBD, especially in small and medium-sized buildings and existing buildings that are not automated. This has once again demonstrated how new business areas can be created through functional cooperation between companies.
