One of the biggest air-related challenges that shopping malls face is cigarette smoke, and there should be a solution in place to avoid guests and staff smoking outside of the entrances. Not having a solution leads to tobacco smoke spreading into the facility and exposing non-smokers to secondhand smoke, odors lingering in and around the entrances, and cigarette ends littering the ground. This creates an unhealthy and unpleasant environment for non-smokers and negatively affects the overall impression of the shopping mall, which in turn can lead to a loss of revenue. Also, not accomodating smokers within the facility will most likely lead to less time in commercial areas and loss of revenue. Additionally, when staff needs to get to inconvenient smoking areas, their smoke breaks become unnecessarily long, which decreases productivity. If they have to use the staff entrance to get to the designated smoking area, there is an increased security risk as well.
During the COVID-19 pandemic, the serious consequences of poor ventilation became very apparent. Poor ventilation means an increased risk of bacteria and viruses spreading, especially in crowded environments such as shopping malls.
