Eurovent has released a case study comparing air handling unit (AHU) energy consumption by energy class. Energy classification for air handling units is designed to help estimate which AHU energy class best suits specific project needs.
The case study demonstrates the differences in consumption and cost of energy associated with the operation of AHUs, depending on their energy efficiency class rated under the Eurovent Certification programme. It presents case studies of typical applications and working conditions for various cities in Europe, which provides guidance on making the right choice in the design and selection of the most suitable product. It further shows a rough value of savings in energy costs over 17 years, which is the typical AHU lifetime assumed in the studies of Ecodesign requirements for ventilation units if an A+ class unit is installed instead of a C class unit.
Eurovent Product Group ‘Air Handling Units’ (PG-AHU) Chairperson, Martin Lenz, said: “Investment costs for AHUs often account for less than 30% of total ownership costs, with energy consumption being the major expense over the product’s lifetime. While investing in slightly more efficient units quickly pays off through cost savings and environmental benefits, decisions remain largely driven by investment costs.”
