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

EAp1 Fundamental commissioning domestic hot water question

Hello, I have a project in which I commissioned and the review comments came back that I did not include the kitchen sinks in my scope of work for the domestic hot water systems? All the literature only states domestic hot water systems in the commissioning scope and to date I have only included domestic water heaters and associated recirc pumps under this "umbrella description". Has anyone else run into needing to include kitchen sinks? If so, what exactly would I need to test on a kitchen sink from a commissioning standpoint?

Hello Andrew. You are correct, only DHW heaters and associated circulating pumps need to be commissioned. On projects in which I've recieved this comment I've responded by stating that the LEED reference guide does not require the commissioning of plumbing fixtures. The reviewer has then awarded the prereq/credit. However, if you were to commissioning a plumbing fixture you would verify the flow/flush rate is consistent the construction documents; or that auto-sensors work per the stated sequence. Hope this help! -dave

Andrew, David, I am doing a project that includes fixtures but no hot water system. I received a similar comment. I am planning on responding that the LEED reference guide does not require commissioning of plumbing fixtures ad you did.
