[Equest-users] Modeling landfill gas as a fuel

[Peter Hillermann]

Energy that is purchased from a third party is EA credit 6 Green Power and
the third party needs to be able to prove that they have REC's (renewable
energy certificates) in order for it to count. Renewables go toward the
project be it building or whatever and have to be purchased by the building
owner. What I was told is that you are not allowed to profit off your
renewable energy if you are going to use it toward LEED for a project. In
order for it to count as renewable I think that the owner of the site would
have to give it to the building owner for free. Call USGBC and ask them to
interpret it for you to see. I usually call the USGBC if I have questions
and I do not understand. I do the same with building code because you never
know how the official interprets it versus one of us that is doing the
project.

 

In order to get EA credit 6 you have to purchase at least 35%  of your
annual electrical consumption from this third party and it is calculated
from the energy model you made in EA credit 1 or you have to go to the US
department of energy commercial buildings energy consumption survey database
to determine the estimated electricity use.

 

This is how I have interpreted the LEED manual.

 

Thanks,

Hi All,

 

I am a little stuck on an approach and wanted to get some guidance from the
eQUEST greats. I have a project that is installing a cogeneration plant (CG)
that will use landfill gas from a nearby landfill.

 

The cogeneration plant is installed on site and all energy generated by the
plant is used on site. However, the operator / owner of the cogeneration
plant, a third party, sells the energy to the building owner.  

 

On the documentation side, would one use the exceptional calculation method
or the renewable energy section (LEED Online Template v2.2)? Usually, the
renewable energy does not have a "purchased" component as in a utility. 

 

How would one go about getting credit for the amount of energy used from
this landfill gas cogeneration plant when that energy is purchased?

 

Thanks for your help.

 

Regards.
