LEED Exam question

The requirement is to provide for 5% of all users measured at peak periods. If the 210 already accounts for peak usage, should you really add the 30 in on top of that?

I agree with the answer of 11 spaces for Tristan's reason that 210 represents the peak occupancy. The calculation of "daily visitors" and "peak occupants" confuses a lot of people, so it's worth clarifying: The daily visitors is the total number of visitors that walk thru the front door over the course of an average day. Since the average day is typically calculated over the course of a year, you sometimes see the word annual in the definition; this is to average out any seasonal differences. The peak visitors or peak a transient is the most number of visitors in the building at any one time, on an average day. Think of this as the busiest time of day for visitors, which could be lunch hour, or some other time of day. You don’t need traffic studies – just a reasonable, realistic estimate will do – the point is to have enough bike parking spaces for the workers in the building plus the visitors at the busy time of day. Many projects put long term bike parking in a garage, storage room or basement to give employees more secure all-day parking, and put short-term racks near the entry for visitors. LEED version 4 makes this distinction, but in 2009 you could spread your total bike space between any long term and short term spaces.
