A lot of LEED is a scam just to make the tree-huggers happy but kill a lot of trees doing it (paper forms DO grow on trees).
Most of the time I get folks who want a LEED project, then are either upset that it will cost more...or want to do things the way they used to get done (incandescent can lights everywhere) but still get the LEED credit.
IMHO
Good LEED ideas for our trade: limiting the amount of power consumed by lighting; provisions for a few possible future electric car charging stations here and there; occupancy sensors to turn the lights off in most of the rooms and offices; daylight harvesting near the windows; metering to keep the Utility billing honest; zoning the switches so that an entire floor doesn't have to be lit up for a few occupied cubicles; dimmers; energy efficient motors; VFDs.
Dumb/worthless LEED ideas for our trade: buying materials based on distance from the worksite; recycled content in our supplies; mandatory recycling; solar panels; wind power; green roofs UNDERNEATH the solar panels; most of the rest of the program.
Fun fights in LEED: the battle between using larger wire sizes to reduce electrical losses and using the smallest size wire possible to reduce the usage of Copper on the job; watching the 'lighting designers' ignore the energy codes...then watching them whine and try to squirm out of redesigning the job to meet them.
