The ventilation system within the Birley Field Academic Buildings&Construction (now Brooks Buildings&Construction) at Manchester Metropolitan University (MMU) was designed and modelled using state-of-the-art computational facilities. The aim was to reduce the energy consumption by improving the natural ventilation throughout the Buildings&Construction using innovative designs. Our team carried out a number of detailed CFD simulations of the air flow for different atrium designs and scenarios which included different seasons and different occupancies, etc. This project involved a meticulous design of three different atria at different elevations, built to face the prevailing south-westerly wind in Manchester. Environmental Impact Assessment of this Buildings&Construction was also evaluated using wind microclimate analysis.
