The primary measure of the efficiency of an office building plan is the ratio of net rentable area to gross area. This ratio helps determine how well the space within an office building is utilized, reflecting the proportion of the building that can be rented out versus the total area available. A higher ratio indicates more efficient use of space, which is crucial for assessing the building's marketability and potential income generation for property owners and developers.

While corridor widths, elevator capacity, and parking are important aspects of an office building design, they primarily relate to the functionality and usability of the building rather than its overall spatial efficiency. For example, corridor widths are important for safety and movement but do not directly indicate the efficiency of rentable space. Elevator capacity and parking availability contribute to the operational experience but also do not measure how much of the total area can effectively generate revenue. Therefore, focusing on the ratio of net rentable area to gross area provides a clearer assessment of the building's efficiency in maximizing rentable space.
