Packaged Electric Equipment.Specified packaged electrical equipment has a heat pump as the primary heating source. Exception(s): ❑ Unstaffed equipment shelters or cabinets used solely for personal wireless service facilities. ❑ Requirement is not applicable. Plans reference page/section: • 3. Cooling equipment economizers:The total capacity of all cooling equipment without economizers must be less than 240 kBtu/h. This project lists 36 kBtu/h capacity without economizers.That portion of the equipment serving dwelling units and guest rooms is not included in determining the total capacity of units without economizers. Plans reference page/section: A 4. Equipment and system sizing.Heating and cooling equipment and systems capacity do not exceed the loads calculated in accordance with Section 503.2.1. Exception(s): ❑ Required standby equipment and systems provided with controls and devices that allow such systems or equipment to operate automatically only when the primary equipment is not operating. ❑ Multiple units of the same equipment type with combined capacities exceeding the design load and provided with controls that have the capability to sequence the operation of each unit based on load. Plans reference page/section: • 5. HVAC Equipment Performance Requirements. Reported efficiencies have been tested and rated in accordance with the applicable test procedure.The efficiency has been verified through certification under an approved certification program or,if no certification program exists,the equipment efficiency ratings are supported by data furnished by the manufacturer. 6. Thermostatic Controls.The supply of heating and cooling energy to each zone is controlled by individual thermostatic controls that respond to temperature within the zone. Plans reference page/section: __.I_ ❑ 7. Heat pump supplementary heat. Heat pumps having supplementary electric resistance heat have controls that,except during defrost, prevent supplementary heat operation when the heat pump can meet the heating load. Plans reference page/section: /- ,8. Set point overlap restriction.Where used to control both heating and cooling,zone thermostatic controls provide a temperature range or deadband of at least 5'F(2.8°C)within which the supply of heating and cooling energy to the zone is capable of being shut off or reduced to a minimum. Exception(s): ❑ Thermostats requiring manual change over between heating and cooling modes. Plans reference page/section: 1 9. Optimum Start Controls.Each HVAC system has controls that vary the start-up time of the system to just meet the temperature set point at time of occupancy. Plans reference page/section: 14 I 10.0ff-hour controls.Each zone is provided with thermostatic setback controls that are controlled by either an automatic time clock or programmable control system. Exception(s): LI Zones that will be operated continuously. ❑ Zones with a full HVAC load demand not exceeding 6,800 Btu/h(2 kW)and having a readily accessible manual shutoff switch. Plans reference page/section: 11.Shutoff damper controls. Both outdoor air supply and exhaust are equipped with not less than Class I motorized dampers. Exception(s): ❑ Gravity dampers shall be permitted for outside air intake or exhaust airflows of 300 cfm or less. Plans reference page/section: Project Title: Ricoh TI Report date: 02/07/15 Data filename: Untitled.cck Page 2 of 5 • 12.Freeze Protection and Snow melt system controls. Freeze protection systems,such as heat tracing of outdoor piping and heat exchangers,including self-regulating heat tracing,include automatic controls capable of shutting off the systems when outdoor air temperatures meet code criteria. Plans reference page/section: /IAA ❑ 13.Separate air distribution systems.Zones with special process temperature requirements and/or humidity requirements are served by separate air distribution systems from those serving zones requiring only comfort conditions;or shall include supplementary control provisions so that the primary systems may be specifically controlled for comfort purposes only. Exception(s): ❑ [503.2.4.8+]Zones requiring only comfort heating or comfort cooling that are served by a system primarily used for process temperature and humidity control. Plans reference page/section: /VD • 14.Humidity control. If a system is equipped with a means to add or remove moisture to maintain specific humidity levels in a zone or zones,a humidity control device is provided. Plans reference page/section: ❑ 15.Humidity control.Where a humidity control device exists it is set to prevent the use of fossil fuel or electricity to produce relative humidity in excess of 30 percent.Where a humidity control device is used for dehumidification,it is set to prevent the use of fossil fuel or electricity to reduce relative humidity below 60 percent. Exception(s): ❑ Hospitals,process needs,archives,museums,critical equipment,and other non-comfort situations with specific humidity requirements outside this range. Plans reference page/section: • 16.Humidity control.Where a humidity control device exists it is set to maintain a deadband of at least 10%relative humidity where no active humidification or dehumidification takes place. Exception(s): ❑ Heating for dehumidification is provided with heat recovery or heat pumping and the mechanical cooling system efficiency is 10 percent higher than required in section 503.2.3,HVAC equipment performance requirements. Plans reference page/section: It`-s6 17.Ventilation.Ventilation,either natural or mechanical, is provided in accordance with Chapter 4 of the International Mechanical Code. ---iiii Where mechanical ventilation is provided,the system has the capability to reduce the outdoor air supply to the minimum required by Chapter 4 of the International Mechanical Code.
