Outdoor air requirements may be designed by which type of professional?

The registered design professional is the correct choice for determining outdoor air requirements because this individual is typically a licensed engineer or architect who possesses a comprehensive understanding of building design and systems. They are responsible for ensuring that the mechanical system designs comply with local, state, and national codes, including the ventilation requirements of the North Carolina Mechanical Code.

This expertise is essential for developing systems that will effectively manage outdoor air intake in accordance with the standards and guidelines that ensure occupant health and comfort. A registered design professional is also equipped to integrate the outdoor air requirements into the overall building design, considering factors such as energy efficiency, environmental impact, and compliance with applicable regulations.

While a licensed mechanical contractor may install the systems and an environmental engineer focuses on broader ecological concerns, their roles do not encompass the same level of responsibility for designing the ventilation systems that satisfy code requirements. Additionally, a mechanical inspector primarily assesses the compliance of installed systems rather than designing or determining air requirements. Therefore, the registered design professional is the appropriate choice in this context.
