REHVA Technical Seminar, October 28, 2011, Brussels, Belgium
Not surprisingly, the greatest environmental impact of used energy in various products occur in the use phase, the production and end-of-life phases have only little impact in life cycle analysis. Several presentations at the REHVA event in Brussels in October 2011 focused on energy products and energy savings in lifetime. The combination of Ecodesign and Energy Labelling Directives ensures that both sides – supply and demand side – are addressed to ensure a dynamic market improvement using tools such as “pushing” and “pulling” to achieve better overall efficiency. Improving energy efficiency of products leads to the adoption of a new highly efficient label “A+++” (nowadays only A-G). Energy labelling will be mandatory and required in advertising.
Recently, the Ecodesign is being adopted for the circulation pumps, electric motors, household refrigerator appliances, televisions and fans. Soon, it will be also boilers, heat pumps, air conditioning and ventilation systems, electrical and fossil-fuelled heating equipment, network and storage data equipments, etc. Energy efficiency will be determined for the fans as being / not being part of final assembly. The air-conditioning systems will be assessed on efficiency and noise, cooling and heating functions, air-to-air rated output less or equal to 12 kW and the type of system (split system, window / wall units, single or double ducts, multi-split). The parts of air-conditioning systems, such as fans, motors and circulators, will be evaluated. The evaluation of ventilation systems will deal with the exhaust air handling units (AHU), roof-top fans, supply AHU, balanced AHU, electrically operated openings / grids, as well as all the controls for each part of the systems.
