Applicable Code Section F Code Provision I Information Required - Must be in permit documents Location in I Building Department Lyes,no,nal Documents Notes For supply and return ductwork located in unconditioned space or outdoors, indicate R-value of insulation on ductwork on plans; identify climate zone; note exceptions taken For supply ductwork located in conditioned space, identify if design supply temperature is < C403.2.8.1 No C403.2.8.2 Duct insulation 55°F or > 105°F and indicate R-value of insulation on this ductwork on plans; note exception taken For OSA ductwork, shafts and plenums, indicate R-value of insulation on these elements on tans per Table C402.1.3 for steel -framed walls; note exception taken Piping Systems Indicate design temperature range of fluid conveyed in piping and thickness of insulation (in NA C403.2.9 Piping insulation P g inches) on hydronic piping plans; or exception taken Piping insulation exposed to Indicate method of protection of pipe insulation from damage / degradation on hydronic piping NA C403.2.9.1 weather plans Economizers Identify in equipment schedules on plans or in MECH-EQ forms all cooling systems requiring air economizer controls na C403.3 Air economizer required Provide MECH-ECONO form indicating systems utilizing air economizer exceptions, including those with water -side economizer in lieu of air economizer; indicate on plans eligible exception(s) taken and measures to comply with exception(s) Integrated economizer Indicate air and water -side economizers are configured for partial cooling operation even na C403.3.1 operation - air and water where additional mechanical cooling is required to meet the load Economizer heating system Verify control method of HVAC systems with economizers does not increase building heating na C403.3.2 impact - air and water energy usage during normal operation Indicate modulating OSA and return air dampers are configured to provide up to 100% OSA na C403.3.3.1 Air economizer capacity for cooling Verify mechanical cooling controls are interlocked with air economizer controls so the outside air damper remains in 100% open position when mechanical cooling is also required to meet na C403.3.1 Integrated air economizer the cooling load, until the leaving air temperature is < 45°F C403.3.3.2 For systems with cooling capacity >_ 65,000 Btu/h, verify that control of economizer dampers is not based only on mixed air temperature; or exception taken na C403.3.3.3 Air economizer high limit Indicate high limit shut-off control method and required high limit per Table C403.3.3.3 controls For eligible systems where water -side economizer may be provided in lieu of air economizer, na C403.3.4.1 Water economizer capacity indicate system is capable of 100% design cooling capacity at 50°F db / 45°F wb OSA temperatures C403.3.4.2 Water economizer Indicate pressure drop across precooling coils and heat exchangers in water economizer na maximum pressure drop system do not exceed pressure drop limit C403.3.1 DX air handling equipment For DX air handlers with economizer and cooling capacity z 65,000 Btu/h, refer to HVAC na control System Controls for requirements DX equipment economizer For DX air handlers with economizer and cooling capacity>_ 54,000 Btu/h, provide a fault na C403.2.4.7 fault detection and detection and diagnostics (FDD) system to monitor economizer system operation and report diagnostics faults Systems Requiring Energy Recovery For systems with design OSA > 5,000 cfm, or design supply air cfm and % OSA exceeding the values in Tables C403.5.1(1) or (2), indicate exhaust air ER method; or exception taken with supporting calculations Energy recovery (ER) - For rooms served by multiple systems with aggregate design OSA > 5,000 cfm, or aggregate na C403.5.1 ventilation / exhaust systems design supply air cfm and % OSA exceeding the values in Tables C403.5.1(1) or (2), indicate exhaust air ER method; or exception taken with supporting calculations Indicate ER rated effectiveness that increases OSA enthalpy by >_ 50% based on delta between OSA and return air enthalpies at design conditions Laboratory exhaust systems For buildings with total lab exhaust > 5,000 cfm, indicate method of energy recovery used to na C403.2.7.2 (energy recovery) pre -condition laboratory make-up air; ER effectiveness (min 25°F); or alternative method per exception (VAV exhaust, semi -conditioned makeup, or CERM calculation) For buildings with pools or spas with water surface area > 200 sf, indicate exhaust air ER C404.10.4 Pools and permanent spas method and use of waste heat (preheat ventilation air, pool water or service hot water); or na (under exhaust systems exception taken C404.11) (energy recovery) Indicate ER system has the rated effectiveness and is configured to decrease the exhaust air temperature at design conditions by >_ 36°F Energy recovery - For buildings with on -site steam heating systems, indicate condensate water ER For buildings that use off -site generated steam where condensate is not returned to the na I C403.5.2 steam condensate systems source, indicate on -site condensate water ER
