The article provides a roadmap for engineers for specifying air handling units (AHU). Topics covered include codes, standards, guidelines, and owner or client expectations that affect the specification of AHU, factors that affect AHU design such as equipment location, and the criteria to consider when specifying AHU, specifically with regards to heating and cooling capacities, humidity control, fan redundancy, air filtration, and efficiency.
