What Is an NRCA Certificate of Acceptance?

The NRCA is the nonresidential Certificate of Acceptance — the document recording that installed lighting controls or mechanical systems were functionally tested and performed as required. It is the only certificate in the family that reports a test result rather than a description.

Where it sits among the others

The nonresidential family runs in stages, and the NRCA is the last of them. The NRCC is the design-stage certificate of compliance submitted for permit. The NRCI is the certificate of installation, completed by the contractors who install the regulated work. The NRCA is the certificate of acceptance, completed after a functional test of the installed system.

That progression is why an NRCA cannot be produced early. The other two describe intent and installation; this one reports behaviour, and behaviour cannot be tested before the system runs.

Which systems produce one

Two disciplines only: lighting controls and mechanical systems. Mechanical tests include outdoor air, air economizer controls, hydronic variable flow, energy management control systems and heat recovery ventilation. Lighting tests cover occupant sensing and automatic time switches, daylight responsive controls, demand response controls and outdoor lighting controls. A project completes the forms matching what it installs.

How to read the form name

Three pieces of information. NRCA is the family. The middle letters are the discipline — MCH for mechanical, LTI for indoor lighting, LTO for outdoor lighting, ENV for envelope. The trailing letter is a rule of thumb rather than an absolute: -A usually requires a certified acceptance test technician (ATTCP), and -F allows a field technician. The Multifamily Compliance Manual's Table 2-4 lists two named exceptions, NRCA-ENV-02-A (fenestration) and NRCA-ENV-03-A (daylight PAFs), which do not require ATTCP certification despite the -A. The table also marks NRCA-MCH-20a through 20d-H and NRCA-MCH-21-H as "ATT-Alternative to Rater FV&DT" — an acceptance test a certified technician may perform instead of rater field verification and diagnostic testing, not a rater-only form.

So NRCA-MCH-02-A is the mechanical outdoor air test, and it needs a certified technician; check the discipline and number against Table 2-4 before assuming the suffix alone settles it.

What makes a completed NRCA valid

Not just a signature. Mechanical NRCA forms must carry the watermark logo of a certified Mechanical ATTCP provider, and lighting forms are completed through an approved provider's database. Those mechanisms let a plan checker distinguish a genuine certificate from a blank somebody filled in, and the authority having jurisdiction requires the certificate to demonstrate compliance.

Where measurement is involved the document also carries the method, the equipment and the calibration dates, with calibration required within one year.
