Would a "green" roof done with synthetic turf apply to this credit under the green roofing option?

I am trying to correctly determine the baseline system for my LEED energy model. I have a 7-story hotel building so it will either be System 1- PTAC or System 2 –PTHP based on ASHRAE 90.1-2007.

I have not been able to find out much info on perf periods, so I have a few questions.

Dear LEEDUsers, We are working towards certifying our own office building (an existing 50 year old, single story structure of ~7,000 sf on a 0.64 ac lot).

we are working on a hotel project where the guest rooms are provided with dual flush (4.5L/3L) WCs. no urinals are provided.

Dear All, Would it be possible to claim EAc1 credits for local automation in dwelling units to achieve the following: (1) Automatic shut down of lighting and HVAC units when there is no occupancy

Has anyone been successful in claiming savings in tenant spaces for anything other then lighting power reductions? Demand controlled ventilation, daylight sensors or plug load reductions perhaps?

Dear Sir/Madam We are certifying a large retail mall which have a large carpark block ( five levels).

We have a multi unit high rise residential bldg. and we are attempting to provide natural ventilation to all units using the operable windows and sliding doors.

We are doing LEED Volume under NC-Retail for a gas station chain that sells E-85 at all locations. Does E-85 qualify as On-Site Renewable Energy?
