Applicable Location in Building Department (yes,no,na) Code Section Code Provision Information Required-Must be in permit documents 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 C403.2.8.1 For supply ductwork located in conditioned space,identify if design supply temperature is< 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 plans per Table C402.1.3 for steel-framed walls;note exception taken Piping Systems C403.2.9 Piping insulation Indicate design temperature range of fluid conveyed in piping and thickness of insulation(in inches)on hydronic piping plans;or exception taken C403.2.9.1 Piping insulation exposed to Indicate method of protection of pipe insulation from damage/degradation on hydronic piping weather plans Economizers 'Identify in equipment schedules on plans or in MECH-EQ forms all cooling systems requiring air economizer controls yes 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) C403.3.1 Integrated economizer Indicate air and water-side economizers are configured for partial cooling operation even operation-air and water where additional mechanical cooling is required to meet the load _ _ C403.3.2 Economizer heating system Verify control method of HVAC systems with economizers does not increase building heating impact-air and water energy usage during normal operation C403.3.3.1 Air economizer capacity Indicate modulating OSA and return air dampers are configured to provide up to 100%OSA for cooling Verify mechanical cooling controls are interlocked with air economizer controls so the outside C403.3.1 air damper remains in 100%open position when mechanical cooling is also required to meet C403.3.3.2 Integrated air economizer the cooling load,until the leaving air temperature is<45°F 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 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, 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 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 2 65,000 Btu/h,refer to HVAC control System Controls for requirements DX equipment economizer For DX air handlers with economizer and cooling capacity z 54,000 Btu/h,provide a fault 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)- C403.5.1 ventilation/exhaust For rooms served by multiple systems with aggregate design OSA>5,000 cfm,or aggregate 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 C403.2.7.2 pre-condition laboratory make-up air;ER effectiveness(min 25°F);or alternative method per (energy recovery) 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 (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 C403.5.2 steam condensate systems For buildings that use off-site generated steam where condensate is not returned to the source,indicate on-site condensate water ER
