This credit talks about a purchasing plan but uses an inventory in lieu in the documentation.

CCFL- Cold Cathode Fluorescent Lamps could be excluded from the calculations? The manufacture just inform this:"Low content of mercury, 20% less than that of CFL. How should I proceed?

Do emergency lights need to be included in this list?

I'm working on a project which is using this credit as an ID credit for LEED-NC. Must outdoor lights be included?

We are having an issue because some animal care lamps of our project do not really disclose the mercury content of the lamps since they consider it as some part of their copyright of some sort.

In order to compare apples to apples (efficiency) lets assume the unit as lumens/Watt.

I have a Core and Shell v2009 project. I've seen that a number of people have been using this credit as an ID credit for NC projects. Is it safe to assume that we can use it for CS also?

I am working a NC project that has only LED lights, can I pursue an Innovation in Design credit as there are no mercury containing lights?

To use this for an ID credit does the average of 90 picograms per lumen hour change to an average of 80 picograms per lumen hour to achieve the point?
