Eu.bac accreditation

juin 25, 2008

Trend’s IQL fan coil unit controllers are among the first products that are allowed to sport the eu.bac accreditation logo. Independent testing showed their control accuracy to be well within the standard necessary to gain this new form of certification, which officially marks them out as providing assured levels of quality and energy efficient control.

The European Building Automation and Controls Association (eu.bac) was set up in 2003 by a group of leading manufacturers – including Trend. Its formation was partly a response to the European Performance in Buildings Directive (EPBD). As well as defining requirements for services such as boilers and air conditioning systems, the directive imposed a framework for calculating buildings’ energy efficiency. In the UK, implementation of the EPBD for non-domestic buildings will begin in 2008, when energy performance certificates will be needed for all new premises and those being rented or sold.

Good control is obviously a pre-requisite for energy efficient operation of a building’s services. Eu.bac accreditation is able to provide reliable, third-party proof that a product has the capabilities to achieve this and – because it requires an inspection of manufacturing facilities – it also assures product quality and consistency. The scheme is initially being applied to individual zone controllers, which have a significant influence on final energy usage.

Trend’s IQL controls were put through their paces by leading independent UK test-house BSRIA, one of three laboratories that eu.bac has authorised to carry out performance testing (the other two being CSTB in France and WSPLab, Germany). Testing was performed using a computer model of the heating/cooling system (4-pipe fan coil unit). To gain eu.bac accreditation, the controllers needed to maintain the simulated space temperature to within +/- 1.4oC of setpoint under three load conditions, in both heating and cooling modes. In the event they proved accurate to 0.2oC, setting a stiff benchmark for products that follow.

With their excellent eu.bac rating, the IQLs will now have even greater appeal to specifiers, designers and end-users as they look to create buildings with lower carbon footprints. Not only can they be confident of the products’ control capabilities but they also have a value that can be trusted in energy performance calculations. In the future this form of rating of controls may well become mandatory.
