Energy Star Portfolio Manager requires that power produced and used on site be included when submitting for an Energy Star rating. (This may be a new requirement as of sometime in 2011; I'm not certain.) But the FAQ section on the Energy Star site says that on site solar power gets a source multiplier of 1.0, which makes it better than utility power at around 3.3 or thereabouts if I recall.
My question is that EA Credit 1 says on site wind and solar are not included in the energy calculations for the credit. Does that mean I should leave out the solar power meter when entering data in Energy Star Portfolio Manager? Or has LEED updated the credit requirements to correspond with the fact that solar and wind are included in Energy Star ratings now, albeit it with a favorable source multiplier?
Thank you.

My understanding is that Energy Star made the update that requires inclusion of onsite solar after the LEED citation you mentioned was issued. Generally, LEED adheres closely/identically to the rules put forth by Energy Star when it comes to benchmarking, and I believe you should follow the up-to-date guidelines from Energy Star for this matter.
