Regarding Renewable Energy Production for LEED certification and also for LEED Zero certification, there is an issue which is kind of not clear to me.

It is related to pellet burning boiler, which is a kind of biofuel.

If the heating of the building is provided by a pellet burning boiler and the pellets are purchased offside, the questions are:

What kind of pellets are excluded as a renewable fuel?
When the pallets are purchased from a producer outside of the project boundary, how is this to be classified – off-side or on-side, meaning that the boiler is on-site?

Your opinion and advises are highly appreciated.

Thanks

It appears that you have asked this question before relative to LEED 2009 projects. https://leeduser.buildinggreen.com/forum/wood-pellets-renewable-energy-source Have you checked the LEED interpretations metnioned in that thread to see if they still apply to v4 projects?

I think pellets only made from mill residue/waste or agricultural waste would qualify. Such pellets would be considered off-site unless they are produced on-site.
