Where should the air handling unit be located according to the guidelines?

The optimal location for an air handling unit, as outlined in guidelines, is behind the parapet and above corridors. This positioning is advantageous for several reasons. Firstly, placing the unit behind the parapet helps to conceal it from view, preserving the building's aesthetic appeal, which is important in maintaining the overall architectural integrity and visual harmony.

Additionally, positioning the air handling unit above corridors allows for efficient space utilization while also taking advantage of the existing structure to minimize ductwork and mechanical systems' intrusiveness within occupied spaces. This location can enhance operational efficiency by allowing for effective airflow distribution throughout the building while also providing easier access for maintenance and repairs, as it is generally located in less congested areas away from high-traffic zones.

Placing the unit elsewhere, such as in front of the building, next to the entrance, or on the roof, presents challenges like site visibility, potential obstruction of pedestrian pathways, increased noise levels in common areas, or exposure to weather elements, which may compromise functionality and design considerations.
