Title 24, Part 6, Section 140.4(r) requires that HVAC control systems with DDC use programming originating from a certified programming library based on control sequences of operation described in ASHRAE Guideline 36. This section describes the requirements of the Guideline 36 programming library.
HVAC Controls technology companies shall certify to the Energy Commission that the Guideline 36 Programming Library meets the requirements of Reference Joint Appendix JA18.
Each company wishing to certify that their Guideline 36 programming library conforms to the Guideline 36 library requirements of Title 24, Part 6, may do so in a written declaration. This requires that a letter be sent to the California Energy Commission declaring that the Guideline 36 library is complete and conforms to the requirements listed in JA18.3. The declaration at the end of this section shall be used to submit to the California Energy Commission.
The certifying company shall provide evidence of compliance with these requirements, including the following at a minimum:
Evidence: List of hardwired points and control points used in the library.
Evidence: Documentation of test plan and results, including inputs and outputs for each test.
Evidence: Documentation of programming, such as screenshots of programming function blocks or programming script.
The programming library to be certified shall include complete control logic for all sections from ASHRAE Guideline 36 listed in Table JA18.4-1, and shall meet the minimum validation requirements listed.
