My project is on a Campus that has used a District Heating and Cooling System and has achieved LEED ID credit in the past. They want me to use this as an ID credit for our CI project. But we are not performing "energy modeling" ours is a small space in a very large building. Would you still seek and ID credit with District Heating and Cooling and wouldn't we need to demonstrate our little space's overall energy use?

Sue, I am not sure on what basis you would seek an ID credit in this case.Can you say more about what the ID credit was achieved for in the past? Maybe I am having a brain block, but I can't recall seeing that simply the existence of district cooling/heating is sufficient for an ID credit. As you point out, in the case of a small CI project without energy modeling, the connection would be even more tenuous.

Tristan thanks for the reply- this system has gained several NC projects an ID credit as well as helped with overall energy efficiency. It's just that they are asking me to apply it to this CI project too, and I can't think of the angle we'd use....

Sue, I would need more info to provide advice on that. How has it been earned on NC projects?

I don't have permission to post this to LEEDuser because it was provided by Davis Langdon for an NC project on campus- did receive credit as an "alternative" compliance path for the energy credits. There was also a CIR written on compliance.

Sue, I don't think that an alternative compliance path (ACP) equates at all to an Innovation credit. So I don't see how one take an ACP for EAc1 under NC, and apply it as an ID credit under CI.

LEED ND offers GIBc12 District Heating and Cooling that could perhaps qualify for a BD+C ID credit, but I don't see how it to leverage it for this LEED CI project above and beyond LEED CI EAc1.3 HVAC.

Following up on this thread, I have a similar project that is LEED-CI with the tenant occupying >80% of the shell and will be doing some innovative energy saving measures with sensors. I wonder if anyone has come across an alternate compliance approach to document energy savings than what is required by EA c1.3, specifically, using a whole building model to evaluate all of the TI's systems. I stumbled across this thread, thinking an ID credit would be most appropriate. Thoughts?
