Q-nis were awarded the contract to supply the AHUs to this mixed use development in London. The project presented a number of challenges. All AHUs were positioned in the building using only the goods lift and therefore every AHU section was limited in size and we then assemble the AHUs in the plantrooms. There was very strict noise criteria on the AHUs and the related external boundary noise criteria due to proximity to residential areas. We demonstrated compliance to meet the noise level requirement and also carried out a factory acceptance test.
