Sorry I did not sufficiently understand.
I thought you wanted the EV charging facilities done in such a way
that they would facilitate getting the desired LEED rating ... not just info on getting "chargers" (or "charging stations") installed.
Biggest questions affecting strategy:
1. who will pay for the Level 2 EVSE (charge stations, not "chargers") or the Level 3 "Quick-Chargers"
2. who will pay for maintaining them
3. who will pay for the operating costs (mostly electricity)
4. will they be "public", or restricted-access (like require an activation card or key, a subscription, being an employee or "visitor", etc.).
Depending upon these fundamental choices, you will probably have some different "constraints" and "options".
Whatever specifics you find will be of interest to some folks here.
