| 11/06/2024 | Commercial Mechanical | REQUIRES RESUBMIT | 1. The submitted calculations do not clearly show that the three apartments have ventilation that meets the minimum requirement for outside air flowrate based on Equation 4-9, Section 403.3.2.1, IMC 2018. [Third comment: The ventilation rate for Group R-2, R-3, and R-4 buildings less than three stories is to be calculated using Equation 4-9, Section 403.3.2.1, IMC 2018. The calculations you have proposed have incorrect arithmetic and you do not cite a source for the calculations. [Second comment: Comment not addressed.] [Initial comment: Assuming that the rooftop heat pumps are new work, provide mechanical ventilation for each apartment. Reference: Section R403.6 (N1103.5), IECC (IRC) 2018.] 2. The two new heat pumps (apartments 2641 and 2643) do not have efficiencies that meet the current standards for both SEER and HSPF. Revise the specifications for the new equipment. [Third comment: The new heat pump for unit 2643 is noted both as new and as existing. Unit 2641 shows a new heat pump. The current minimum rating for single-packaged heat pumps is 13.4 SEER2, 6.7 HSPF2 (14 SEER, 8 HSPF).] [Second comment: Clarify the status of the rooftop units and their energy efficiencies. The proposed equipment schedules show different SEER values than the HVAC Equipment boxed note and in one area the 2-ton unit is existing and it is new in another note. The 3-ton unit is similarly new in one place and existing in another place.] [Initial comment: Assuming that the rooftop heat pumps are new work, show the complete specifications for each heat pump system, including the SEER and HSPF for each unit, any supplemental heaters, and the air leakage rating of the air handler (ASHRAE Standard 193). Reference: Sections R103.2, R403.7 and R501.5, IECC 2018.] |
