Reliable Controls is now a member of the BACnet Interest Group Europe (BIG-EU). The BIG-EU is the European trade association for the application of the global BACnet standard ISO 16484-5.

Objectives of the BIG-EU include promoting the spread of best practice solutions, coordinating the European BACnet activities and globally representing the interest of European members, and ensuring interoperability of different building automation components

The group is also responsible for certifying conformance according to the BACnet standard ISO 16484-5, contributing to guidelines, and providing unbiased marketing and training.

According to Reliable Controls, the group demands prevalence of the BACnet standard in Europe because systems that communicate with each other in a single language are far superior to isolated solutions. The BIG-EU represents European interests in the development of the norm and coordinates the European BACnet activities. Reliable Controls launched a European Authorized Dealer Network in March 2014.
