<br /> Project Title: Dr.Amy Norman Date 6/5/2018
<br /> The following information is necessary to check a permit application for compliance with the mechanical systems and equipment requirements of the
<br /> Washington State Energy Code,Commercial Provisions.
<br /> Applicable Code Section Code Provision Information Required-Must be in permit documents Location in Building Department
<br /> (yes,no,na) Documents Notes
<br /> For buildings with food service,meat or deli departments that have z 500,000 Btu/h of remote
<br /> refrigeration capacity for coolers/freezers,indicate condenser ER and use of captured energy
<br /> (service water heating,space heating,or dehumidification reheating)
<br /> C403.5.3 Energy recovery-
<br /> cooler/freezer condensers For buildings with z 40,000 sf conditioned floor area and with z 1,000,000 Btu/h of remote
<br /> refrigeration capacity for coolers/freezers,indicate condenser ER and use of captured energy
<br /> for service water heating and also for space heating,or dehumidification reheating
<br /> For buildings with 24-hour operation and with>1,500,000 Btu/h of heat rejection capacity and
<br /> C403.5.4 Energy recovery- design service hot water load>250,000 Btu/h,indicate condenser ER to pre-heat service
<br /> condenser systems water;or exception taken.Provide calculations showing the amount of recovered heat that is
<br /> utilized(60%of peak heat rejection load or pre-heat service water to 85°F).
<br /> Hydronic System Controls
<br /> For hydronic system pump motors z 7.5 hp,indicate method of variable flow control(VSD or
<br /> C403.2.13 Variable flow control- equivalent method that requires z 30%design wattage at 50%design fluid flow);note
<br /> C403.4.2.7 hydronic system pumps exception taken
<br /> Identify whether hydronic coils have DDC controls and associated manner of pump speed
<br /> control(differential pressure,zone hydronic demand,etc)
<br /> For boilers that provide building heating,indicate controls that provide heating water
<br /> temperature setback based on outdoor temperature
<br /> For heating and chilled water systems z 300,000 Btu/h,indicate systems are configured to
<br /> 0403.2.5 Hydronic system setback automatically reset supply water temperature based upon demand;or exception taken. u
<br /> 0403.4.2.4 and part load controls If system pump motor hp z 3 hp,also indicate controls automatically reduce flow by z 50%
<br /> For chilled water systems(z 300,000 Btu/h,pump motor hp>_3 hp)that serve water-cooled
<br /> unitary air conditioners,indicate VSD or staged pumps in chilled water system and heat
<br /> rejection loop that reduce pump flow so that one control valve is nearly wide open,or to
<br /> maintain a minimum differential pressure;or exception taken
<br /> 0403.4.2 Boiler sequencing Indicate automatic controls that sequence operation of multiple boilers
<br /> 0403.4.6 Hot gas bypass limitation For cooling equipment with hot gas bypass,provide either multiple step unloading or
<br /> continuous capacity modulation;indicate bypass capacity per Table 0403.4.6
<br /> 0403.4.2.2 Two-pipe changeover Indicate changeover deadband(min 15°F),heating/cooling mode scheduling and
<br /> systems changeover temperature range(limit 30°F)
<br /> 0403.4.2.6 Chiller/boiler plant pump Indicate controls are configured to automatically reduce overall plant flow and shut-off flow
<br /> isolation through individual chillers and boilers when not in use
<br /> For cooling towers with fan motors z 7.5 hp,indicate VSD and method to adjust fan speed
<br /> 0403.2.13.1.1 Heat rejection equipment- (adjusted based on leaving fluid temperature or condenser temperature/pressure of heat
<br /> C403.4.3.1.1 variable flow control rejection device)
<br /> C403.4.3.1.2 For multiple-cell heat rejection equipment with VSD,indicate controls that ramp all fans in
<br /> unison
<br /> C403.4.3.3 Heat rejection equipment- Indicate open-circuit cooling towers with multiple pumps or VSD control are designed so all
<br /> cooling tower flow turndown cells can be run in parallel
<br /> C403.4.2.3.1 Water loop heat pump- Indicate capability of central equipment to provide minimum 20°F water supply temperature
<br /> deadband deadband between heat rejection and heat addition modes;or exception taken
<br /> Water loop heat pump- Indicate type of cooling tower(open-or closed-circuit)in equipment schedule;indicate method
<br /> 0403.4.2.3.2.1 heat rejection equipment, used to limit system heat loss when heat rejection is not needed
<br /> Zone 4
<br /> Water loop heat pump- For open-or closed-circuit cooling towers,provide a heat exchanger that separates the cooling
<br /> 0403.4.2.3.2.2 heat rejection equipment, tower and heat pump loop
<br /> Zone 5
<br /> 0403.4.2.3.3 Water loop heat pump- For hydronic heat pump systems with total system power>10 hp,indicate 2-way isolation
<br /> isolation valves valves on each heat pump and variable flow system control
<br /> Dedicated Outdoor Air Systems(DOAS)-Optional through 6/30/16,Prescriptive 7/1/2016
<br /> For buildings with office,retail,education,library and fire station spaces,identify these spaces
<br /> C403.6 Dedicated outdoor air on plans;indicate that ventilation air in each occupied space is provided via a DOAS system;
<br /> C403.6.3 systems or document compliance with 0403.6.3 Impracticality;or exception taken(buildings complying
<br /> with C402.4.1.4 or C406.6 may not utilize exceptions)
<br /> Energy recovery ventilation For all DOAS systems,indicate exhaust air ER method;or exception taken with supporting
<br /> 0403.6.1 calculations.Indicate ER rated effectiveness that increases OSA enthalpy by>_50%based on

<br /> Indicate equipment associated with the delivery of zone level heating and cooling(fans,
<br /> Heating/cooling system hydronic pumps,primary air dampers,etc)are configured to shut off,and central equipment is
<br /> 0403.6.2 controls with DOAS configured to turn down,when there is no call for heating or cooling in the zone they serve
<br /> If applying Exception to heating/cooling fans used for air mixing in the space during deadband
<br /> periods,include fan watts per cfm in equipment schedule
