| 06/17/2020 | ROBERT SHERRY | MECHANICAL-COMMERCIAL | REVIEW | Reqs Change | Revise sheet M-4 by removing the COMcheck Mechanical Compliance Certificate. The Building Official has determined that exception (5) of C403.5, IECC 2018 eliminates all of the economizer requirements of C403.5, IECC 2018. Show the IEER for the two 32-ton heat pumps in your equipment schedule. [Initial comment: Replacement of existing HVAC equipment is considered to be new work and as such must comply with the current code requirements. Economizers are required for systems with a cooling capacity greater than 54 MBH or systems with efficiencies 10% greater than the minimum efficiency requirement of Table C403.3.2 (1), IECC 2018. For the two split systems in question, the minimum EER would be 11.2 or an IEER of 12.8. Reference: Exception (5), Section C403.5, IECC 2018.] |
