FAQs about EAp1 :

Our project is considering LEED after construction has begun. Can we meet the EAp1 requirements and thus be eligible for LEED certification?

Can the CxA be a member of the design or construction team?

What type of certification is the CxA required to have?

The commissioning process turned up a few issues with the commissioned systems that should be corrected. Do we have to correct these issues and include documentation of that as part of our LEED documentation?

Can the CxA be contracted through the general contractor if the owner requires a single contract for the project?

For a building with individual systems per unit, does every single system need to be commissioned?

What kinds of projects must the CxA demonstrate experience on?

What level of authority does the CxA have towards correcting inaccurate or erroneous construction?

NC-v4 EAp1:Fundamental commissioning and verification

District Energy Cx Guidance

Hello, We have a project that meets the requirements of District Energy Systems. There is one new piece of equipment and multiple existing that will serve the facility. In thinking through the commissioning scopes for these two categories of plant, do we apply LEED V4 Fundamnetal Cx to the new equipment? Then, what do we apply to the existing plant equipment? LEED EBOM 2009 c2.1 and c2.2 or 2.3 as it was under the LEED 2009 rating system? Or, do we still follow the DES Guide for both plant scenarios? Thank you, Candice Rogers

I am a little confused by your "two different plants" notation. Once you meet the definition of a DES, even if you have to add equipment to that plant, it is a DES still. In the v4 guide under Project Type Variations, it is pretty clear that "All upstream equipment is excluded from the scope of this prerequisite." This is fundamental. If pursuing enhanced, they make it slightly more complex. Upstream is exempted if the project is not taking credit for the efficiency of the DES. If you are taking advantage of the DES, then under enhanced, then it will need to be included to various levels depending on age. Again, look under Project Type Variations in the guide for enhanced commissioning for more detail on the scope requirements.

Scott - I just reread the credit language in the LEED v4 manual. All questions on the requirements are listed in there. Page 401, clear as day. Thank you - Candice
