Coastal and Floodplain Construction Inspector's Practice Exam

In coastal areas, where should HVAC equipment be situated?

1. On the roof of the structure

2. On the landward side of the structure

3. At ground level

4. In a separate building

The correct answer is: On the landward side of the structure

In coastal areas, situating HVAC equipment on the landward side of the structure is essential for several reasons related to safety, functionality, and code compliance. Positioning the equipment in this manner protects it from storm surges and flooding, which can occur in coastal regions during extreme weather events such as hurricanes or nor'easters. By placing HVAC systems landward, builders can reduce the risk of damage from saltwater intrusion, which can corrode metal components and electrical connections. Moreover, local building codes often require that critical mechanical equipment be located above the base flood elevation to minimize the potential for flood damage. Placing HVAC units on the landward side allows for easier access for maintenance and service while still adhering to these regulations. Other placements, such as on the roof, at ground level, or in a separate building, may not provide the same level of protection from environmental hazards or compliance with safety standards in flood-prone areas. Positioning HVAC equipment correctly is crucial for ensuring its longevity and reliable operation in the face of coastal challenges.
