Is this calculated as the gross energy cost (i.e. without reducing energy cost with the renewable energy offset) or the net energy cost?

In the reference guide of LEED ID+C V4,  it is mentioned under prerequisite  the newly installed plumbing fixtures must be according to the Table 6 flow rates.

As per Version 4.1, IEQ Credit-Daylight: Options 2, Illuminance calculations. 

Which plumbing equipment are applicable in this credit? Does this includes lavatories, kitchen sinks and showersheads? Thanks in advance.

How is furniture defined? I'm working on an adult education building that has large trash, recycling, and compost bins in the the classrooms since meals are regularly served.

Is a soil test needed both before and AFTER construction to show that soil has been restored? We are tyring to understand how to document the restoration of the soil.

I'm wondering if anyone knows what specifically is needed in order to get the Heat Island credit? The project has a 5 story, above ground parking garage without a roof on the top level.

Can anyone please help me understand what is needed for Daylight in nonregularly occupied spaces, option 2?
