According to the 2018 NCMC, what is the ventilation rate for people only in cubic feet per hour for a 5000 square foot general office building?

According to the 2018 NCMC, what is the ventilation rate for people only in cubic feet per hour for a 5000 square foot general office building?

• A. 5000 cfh
• B. 7500 cfh
• C. 10000 cfh
• D. 12000 cfh

Answer: (B)

For a general office building, the ventilation rate according to the 2018 North Carolina Mechanical Code (NCMC) is typically based on the occupancy and the area of the building. The code generally stipulates that the ventilation rate should be calculated using a formula that considers the number of occupants and the specific requirements for indoor air quality. In this scenario, to determine the ventilation rate for a 5000 square foot office building designed for people, the calculation would follow guidelines that recommend a specific airflow per person. The standard ventilation rate usually cited in such contexts is around 15 to 20 cubic feet per minute per person. When you convert this to an hourly rate and multiply it by the number of expected occupants based on square footage, you arrive at a figure consistent with the provided answer. The answer of 7500 cubic feet per hour (cfh) aligns with these calculations for a general office setting, considering both the typical density of occupants and the requirements outlined in the NCMC. Thus, choosing this option reflects an understanding of how to apply the code's guidance to practical scenarios in building ventilation.
