FAQs about EAc1.3 :

If pursuing Option 2, what is the scope of the energy model if the space shares a central plant, and what type of software should be used?

For Option 1, Zoning and Controls, is a thermostat considered an “active control capable of sensing space demand"?

CI-2009 EAc1.3:Optimize Energy Performance—HVAC

"relevant criteria"

The project can comply with the requirements of the credit if the project team can show that the relevant criteria have been met for all HVAC systems serving the area within the project scope, whether or not the HVAC systems are installed as part of the tenant scope of work. What is meant by "relevant criteria"? Do the HVAC systems have to comply with EAp2, Min. Energy Perf. to be used in this credit?

The relevant criteria refers to the issue LEED requires you to address. For example if following Option 1 Equipment Efficiency you can earn those points if the HVAC systems meets the requirements and it does not matter if the equipment in question was part of the tenant scope or work or not.

Ok, when following Opt 1 it seems to be clear. But what about Option 2 - the requirement by Opt 2 is to is to meet at least 15 % energy savings, there are no individual requirements for the devices in Opt 2. Example: Central HVAC-systems are not included in the tenant scope. However we would like to pursue EAc1.3. Unfortunately the COP of the chiller in the basebuilding does not fulfill the minimum requirements of EAp2. If our simulation results in an energy saving > 15 % are we eligible for this credit?

Can you even get to 15% HVAC savings with a non-compliant chiller? Since the chiller is not in the tenant scope it does not have to comply with the mandatory provisions under the prerequisite. Option 2 does not require compliance with the mandatory provisions in the credit language so if you can show the 15% I would think you could earn the points under this credit. I am not sure if this would be prohibited elsewhere like in the Reference Guide so you should check to be sure.

Hi Marco and Marcus, I have very related situation for one of my projects. Were you able to achieve 15 percent savings? Did LEED approve it? "Project Scope" in the above statement implies all the mechanical equipments serving the LEED project boundary or just within tenant scope of work? Thanks!

In general CI only addresses the tenant scope of work.
