I am exploring the point at which a light rail station becomes eligible for LEED certification under LEEDv4. It was slightly clearer in the MPRs for 2009, but not entirely. Does anyone have thoughts on whether the following are necessary for LEED eligibility now?
- A conditioned space like a bathroom
- A conditioned space that meets the definition of regularly occupied - i.e. beyond a bathroom or staff break room
- Occupancy by at least one staff/employee for an eight hour period. What would happen if occupancy by staff was in less than an hour chunks spread out over 24 hours of operations? What if it totaled .5 FTE?
- No staff occupancy but visitors using conditioned restroom.

I think you get the idea. Is the answer as simple as - as long as you can meet the prereqs and earn enough points? If so, what is your opinion on whether regularly occupied condition space is necessary for energy and ventilation prerequisites?

Thanks for your thoughts.
