The European Energy Performance of Buildings Directive (EPBD) aims to foster the utilisation of renewable energy sources in the building sector, advancing an energy transition to bolster climate protection.
To achieve this, efficient and cost-effective solutions are essential to reduce energy costs in small and medium-sized buildings. WAGO has introduced a comprehensive range of sensor data for existing building management systems by integrating its products with EnOcean technology. This solution, operating within the 868 MHz radio frequency range, provides a foundation for reliable data transmission and is optimised for building automation, even with a high density of sensors.
Reducing energy costs in buildings
The EPBD mandates the phase-out of fossil fuels in buildings by 2045. While this may seem distant, it is imperative for owners and landlords of small and medium-sized buildings to act promptly.
“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,” said Wolfgang Arndt, Senior Territory Manager, Electrical Products Germany at Honeywell PEHA.
This involves integrating diverse sensor data into existing building management systems and ensuring seamless data transfer. At Light & Building 2024, Honeywell PEHA and its partner WAGO unveiled an innovative solution leveraging proven EnOcean technology, supporting flexible use of formats such as BacNet Secure, MQTT, or Cloud.
Universal integration solution
“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,” added Wolfgang Arndt.
The collaboration between WAGO and Honeywell PEHA has produced a system that integrates a wide variety of sensor data into existing building management systems using secure EnOcean technology. The diverse PEHA field device products enable extensive sensor data transmission to the WAGO Compact Controller via the PEHA gateway. Up to 16 gateways/antennas can be connected in parallel using a standard protocol (RS485), eliminating the need for additional antennas and repeaters.
The antennas operate bidirectionally, allowing clear assignment of various field devices. “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,” commented Holger Beland, Senior Area Sales Manager Industry at WAGO.
The solution developed by WAGO, Honeywell PEHA, and EnOcean enables data from the Compact Controller to be integrated into building automation systems using various connection options. Whether using Modbus, BacNet Secure, MQTT, or Cloud, operators can choose on-site which field level the data enters in their building automation system. This flexibility allows operators to defer decisions until integration, maintaining adaptability.
Ensuring compliance with EPBD requirements
“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,” explained Holger Beland.
This efficient and cost-effective solution facilitates the implementation of EPBD requirements, particularly in small and medium-sized buildings and existing buildings lacking automation.
