Guide compares AHU energy consumption
14th January 2025
BELGIUM: Eurovent has released a case study examining the differences in air handling unit energy consumption by energy class.
Energy classification for air handling units is designed to enable potential purchasers to select the most suitable product to suit specific applications.
The case study presents typical applications and working conditions for various cities in Europe and provides guidance on making the right choice based on energy efficiency class ratings under the Eurovent Certification programme.
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.
“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,” explained Eurovent AHU product group chair Martin Lenz.
“While investing in slightly more efficient units quickly pays off through cost savings and environmental benefits, decisions remain largely driven by investment costs. Earlier in 2024, Eurovent published Recommendation 6/19-1: Life Cycle Cost Calculation for AHUs. This new case study builds on it, offering clear examples to highlight the impact of efficiency on lifetime costs.”
