The occupant density for the Lobby is listed as 30 people per 1000 sq. ft. Suppose the area of a lobby is 710 sq. ft. The spreadsheet set up by a coworker is calculating the space occupancy as 21300 people. What is wrong with the spreadsheet? The space occupancy is the number of people which the ventilation system will have to account for when used in other calculations. Keeping this in mind, how should the correct space occupancy be rounded? Using the example below as a model and referencing the provided floor plan, complete the Outside Air Requirements Table for the remaining spaces: library, conference room, corridor, multi-function lobby/reception. Compare the outside air requirements for each space and discuss the results with your group. Note: Demonstrate each calculation explicitly using an equation editor, as in the example Outside Air Requirements.
