Olympic Stadium, London

Q-nis supplied 37no AHUs to the London Olympic Stadium transformation project. The AHUs were complete with EC plug fans, fully pre-wired with internal BMS equipment and internal control boards. The AHUs were acoustically treated to reduce noise breakout and also selected to achieve the specific fan power requirements as per Part L building regulations. We also undertook the upgrade of an existing 20no AHUs involving new motors, filters etc. We assembled and bolted all AHUs together on site. Q-nis supplied all twin toilet extract fans and kitchen extract fans (approx 50no in total). Q-nis provided a full acoustic analysis of the AHUs and extract fans to size and select the best acoustic solution to achieve the require NR levels. As a result we supplied over 60no attenuators. Finally we have supplied all grilles for the stadium from players changing rooms, VIP areas and reception area etc.
