Existing cooling towers are <br />the text box provided <br />at the end of their useful life and need to be replaced. <br />❑Total Bldg Performance (TBP) <br />This path includes all mandatory <br />provisions per C401.2 Option 2. <br />MECH-SUM, MECH-CHK, and C407 <br />Energy Analysis forms required. <br />❑ Load calculation summary ❑ MECH-LOAD-CALC Form <br />Design Load Calculations <br />Provide design load calculations for all mechanical systems and equipment serving the building heating, cooling or <br />ventilating needs. If a load calculation summary is provided with the permit documents that includes all applicable <br />compliance information then the MECH-LOAD-CALC form is not required. <br />Mechanical Plans ❑ MECH-EQ Forms (TBD) <br />Mechanical Schedules <br />Indicate location of equipment compliance information. If provided on plans then MECH-EQ forms are not required, <br />however, include on plans all applicable compliance information listed in MECH-EQ tables. <br />❑ DOAS is required per C403.6 effective July 1, 2017 (office, retail, education, library and fire station occupancies) <br />All occupied, conditioned areas shall be served by a DOAS that delivers required ventilation air in a manner that does <br />not require space conditioning fan operation. Space conditioning fans cycled off when no heating or cooling is required. <br />Dedicated Outdoor Air <br />❑ Ventilation provided via natural ventilation per 2015 IMC in lieu of DOAS (C403.6, Exception 1) <br />System Requirements and <br />❑ Ventilation and space conditioning provided by a HEVAV system per C403.7 in lieu of DOAS (C403.6, Exception <br />High Efficiency VAV <br />❑ DOAS included in project, although not required (occupancy not office, retail, education, library or fire station) <br />Alternate <br />❑ <br />DOAS related allowances included in project: <br />❑ Prescriptive vertical fenestration maximum area allowance increased to 40% per C402.4.1.4 with 100% of <br />conditioned floor area in building served by DOAS. <br />❑ Exception to air economizer per C403.3 Exception 1, include MECH-ECONO form. <br />❑ Project includes HVAC air distribution systems that provide heating and/or cooling <br />If yes, provide a MECH-FANSYS -SUM form. <br />Fan Power <br />❑ For one or more systems, the total fan motor nameplate hp of all fans in HVAC system exceeds 5hp. <br />If yes, provide a seperate MECH-FANSYS form for each HVAC system exceeding the 5 horsepower threshold. <br />Refer to Section C403.2.11 and MECH-FANSYS-DOC for requirements and exceptions. <br />❑ Hydronic chilled water El Water -loop heat pump ❑ No hydronic systems <br />HVAC Hydronic Systems <br />❑ Hydronic heating water ❑ Geothermal <br />❑ C406.2 More efficient HVAC equipment and fan systems <br />Requires 90% of heating and cooling capacity to be equipment listed in tables C403.2.3(1)-(9) or air -to -water heat <br />pumps and heat recovery chillers. All equipment listed in tables C403.2.3(1)-(7) must be 15% more efficient than <br />minimum requirements. All stand alone supply, return, and exhaust fans over 1 hp must have FEQ >_ 71 and must be <br />C406 Additional Efficiency <br />selected within 10% of maximum total or static pressure. <br />❑ C406.6 Dedicated outdoor air system (DOAS) <br />Options - Mechanical <br />Requires 90% of conditioned floor area to be served by a DOAS per C403.6 that delivers required ventilation air in a <br />manner that does not require space conditioning fan operation. <br />❑ C406.7 Reduced energy in service water heating <br />Requires 90% of floor area be in occupancy types listed in C406.7.1 and that 60% of annual hot water energy use be <br />provided by heat pump, waste heat recovery or solar water -heating systems. <br />M\ 1' , rO� <br />
