FAQs about EAp1 :

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

What type of certification is the commissioning agent required to have?

The comissioning 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?

NC-2009 EAp1:Fundamental Commissioning of Building Energy Systems

Installed HVAC equipment is less efficient than simulated.

Hi to all: At the end of the project and after the leed design submittal was reviewed and approved, we found that some of the equipment that have been installed in our project are less efficient than what they should have been based on the approved construction submittals, and that issue reduces the cost savings calculated in the energy model. For this case, what happens now with the certification? We will be indicating in the Cx Plan this issue, but is this a reason for not earning the certification?

Hello Gustov, Design credits are not awarded during the design submission, rather they are anticipated - for instances such as this. My advice would be to include this observation within the issues log and also address it within the resolution plan. If the owner is committed to resolving this issue in a timely manner.... the energy model will not need to be adjusted. Scott, any additional comments/advice? thank you.

I agree with David, if there is a resolution that is being implemented to address this issue that was uncovered during Cx. What would concern me is how it happened in the first place. If approved submittals were not followed, is there some contractual clause that allowed this? Was a change order issued and accepted? Is there some design/build issue that allowed this to happen? If the owner is not going to require contractors to comply with the design, then the energy model does need to be adjusted to meet as constructed conditions, and again David is right, EAc1 is a credit that will be reviewed during construction if you have changes. Hopefully this can get resolved well for your project!
