What is the minimum required outdoor ventilation air for a 2000 square foot florist shop?

To determine the minimum required outdoor ventilation air for a 2000 square foot florist shop, it is important to refer to the standards set by the applicable codes, specifically those concerning commercial ventilation. In many building codes, the required ventilation is often calculated based on the occupancy type and the floor area.

For commercial spaces, the ventilation requirement typically involves a specific cubic feet per minute (CFM) value per square foot of area. In this case, a florist shop, which is considered a commercial establishment with some specific activity levels, would require a certain amount of outdoor air to ensure adequate air quality for both employees and customers.

In the scenario presented, the correct choice of 225 cfm likely aligns with the calculated needs based on the flower shop's usage, which might consider factors such as the potential for moisture (from water used on flowers), the types of activities taking place (such as arrangements and possibly the presence of gases from plants), and the number of occupants during peak hours.

Thus, this specific ventilation requirement helps ensure that the space maintains a healthy air quality, minimizes airborne pollutants, and promotes a comfortable environment. The selection of this figure supports compliance with health and safety standards established in the building codes, catering to both environmental impact and occupant welfare
