eu.bac System: Systematic Evaluations of the Efficiency of Building Automation

In all, seven auditors from WAGO were trained in the “eu.bac System” to support building operators and automation experts in topics related to energy efficiency and sustainability.

DGNB, HQE, LEED, or BREEAM: There is an entire series of certification programs across the breadth of the construction fields. Each of them has a specific focus and also takes different regional circumstances into account. They all provide valuable contributions to ecofriendly and economical buildings. However, these certification processes have not sufficiently considered the operation of the building services in use or building automation.

In order to comprehensively consider building services and building automation within the context of their own certification, a structured, standardized, and scientifically validated evaluation method — the eu.bac System — was developed in 2013. The primary goal was to ensure that building automation systems were designed, installed, and operated in order to provide the optimum comfort, while also being sustainable and energy efficient. A check list was developed that is based on scientifically tested data and the relevant Europeans standard, DIN EN 15232. Audits were carried out by qualified experts, who had been previously trained and approved by the “European Building Automation and Controls Association”, an association of European manufacturers of building automation systems.

The “eu.bac System” closes the loopholes left in those systems that do not focus on building services. However, as the operation of these same building services is often the source of higher costs, systematic evaluation of these systems and measures derived from these examinations can achieve significant savings. This is equally true for existing buildings and new construction. As a partner in the “eu.bac System”, WAGO made a decision to further expand the scope of uilding Automation services: a total of seven colleagues from Project Sales Building Automation have been trained in the “eu.bac System” and approved as auditors. Over the course of an audit, they provide transparency and comprehensively inform the operators about the state of the technology. Together with in-house technicians or service providers, they can develop an approach for improvement.

There are several steps involved in becoming a “eu.bac System” auditor: all candidates have to complete a training program that takes several days and concludes with an exam. The newly-minted junior auditors must complete their first audits within the next six months. The approach and result are examined by experienced, independent “eu.bac System” auditors. Following a successful audit, eu.bac provides the building evaluated with a label that must be rechecked at regular intervals. Building operators benefit from this high quality awareness, as the systematic evaluation according to the “eu.bac System” guaranties the efficiency and sustainability of a building, which in turn reduces energy consumption and operating costs over the lifetime of the building systems. More information about the “eu. bac System” is available at http://system.eubac.org.
