Our projectteam has suggested buying a percentage of biogas from the supplier for use in the boilers as fuel for the site-wide heating system. Does anyone have experience of this approach applying for EAc2 Onsite Renewable Energy?
The selected biogas fulfills the Credit definition of biofuels (derived from animal waste), but this refinement of waste --> gas occurs off site. It is only the second-stage conversion of biogas --> useful heat energy for our project that will be occuring on site.
Any thoughts / experience gratefully received!

Victoria, according to the LEED Reference Guide, purchase of biogas for use onsite qualifies for this credit.

For another project in Italy, we are planning to do the same only with biomass (untreated wood waste) instead of the biogas. It will be bought from the supplier and burnt on site to produce heat. My understanding is that it should be eligible for eac2, but I would appreciate any input.

Sounds like it should be eligible. The only issue may be the "on-site" criteria. Check the LEED Interpretations on this issue and if your situation is not clearly addressed you might want to submit one.
