Mechanical Requirements List, pg 10 of 25 <br /> 2018 WSEC Requirements for Commercial Buildings including Group R2,R3&R4 over 3 stories&all R1 -- Administered by©2021 NEEA,All rights reserved <br /> The following information is necessary to check a mechanical permit application for compliance with the mechanical systems and equipment requirements in the <br /> Washington State Energy Code,Commercial Provisions. <br /> For questions about this report,contact WSEC Commercial Technical Support at 360-539-5300 or via email at com.techsupport@waenergycodes.com <br /> C404.11.4 Exhaust system For buildings with pools or spas with water <br /> energy recovery for surface area>200 sf,indicate exhaust air <br /> heated indoor pools energy recovery method and use of waste heat <br /> and permanent spas (preheat ventilation air,pool water or service <br /> hot water);or exception applied <br /> Indicate energy recovery system has the rated <br /> effectiveness and is configured to decrease <br /> the exhaust air temperature at design <br /> conditions by>36°F <br /> HVAC CONTROLS <br /> YES C403.4.1 Thermostatic controls Indicate locations of thermostatic and M201 <br /> (thermostats and humidity control devices and the zones they <br /> humidistats) I serve on plans,including perimeter system <br /> zones <br /> Where adjacent(neighboring)zones are <br /> controlled by separate thermostats(including <br /> perimeter systems used to offset heat gain or <br /> loss),and are connected by permanent <br /> openings>10%of either zone sf area, <br /> indicate controls configured to prevent <br /> adjacent zones from operating in conflicting <br /> modes(one in heat,other in cool);applies to <br /> adjacent perimeter-zones,adjacent <br /> nonperimeter zones,and adjacent perimeter <br /> and nonperimeter zones <br /> If applying Exception 2 to nonperimeter zones <br /> adjacent to perimeter zones,indicate that <br /> setpoints and deadband settings in these zones <br /> are coordinated so cooling in a nonperimeter <br /> zone does not occur until the temperature in <br /> that zone is 5°F higher than the adjacent <br /> perimeter zone temperature in heating <br /> YES If applying Exception 3 for DOAS,indicate M001 <br /> supply air temperature heating setpoint is 5 <br /> 65°F and cooling setpoint is>_72°F,or <br /> method of supply air temperature reset <br /> NA C403.4.1.1 Heat pump Indicate staged heating operation with <br /> supplementary heat compression as the first stage of heating and <br /> supplemental heating controlled with outdoor <br /> lock-out temperature set to 40°F or less <br /> C403.4.1.2 Deadband Indicate zone thermostatic controls configured <br /> with 5°F minimum deadband for systems that <br /> control both heating and cooling <br /> C403.4.1.3 Setpoint overlap If separate heating and cooling thermostatic <br /> restriction control devices are used to serve a zone, <br /> (thermostats) indicate locations of both thermostatic control <br /> devices and the zone they serve on plans <br /> Indicate a limit switch,mechanical stop or <br /> DDC control with programming to prevent <br /> simultaneous heating and cooling <br /> Page 10/25 <br />
