From my reading of the Reference Manual for this credit it seems that Bio-fuel can only be used to generate electrical power on-site, and not to power bio-fuel boilers for water heating or space heating. Is this interpretation correct? In that case only something like a mini-CHP unit burning bio-fuel is eligible going the bio-fuel route. And even then you are restricted in the bio-fuel you can use, ie. it pretty much needs to be ethanol produced from food waste - is this correct? I don't know of any bio-gas or wood chip CHP systems...

While the language in the Reference Guide has not been changed, it is in error. Eligible bio-fuels can be used directly and do not have to be converted to electricity. The list of eligible bio-fuels includes untreated mill residues, agricultural waste/crops, landfill gas and animal/organic waste.
There is a long history in LEED allowing the improtation of landfill gas to be burned and used for heat not just electricity.

Thanks Marcus, the Reference Guide is definitely misleading on this point so your clarification is very useful.

Could you be a bit more specific with your question? Which limit are you referring to? Apply for LEED Certification?

I beg your pardon. I posted the question above at this point by error.
