Checkmarks identify requirements that the applicant acknowledges are met or excepted from compliance. 'Plans reference page/section'identifies where in the plans/specs the requirement can be verified as being satisfied. Requirements Specific To: HVAC System 1 : • 1. Equipment meets minimum efficiency: Heat Pump: 2.83 COP 9.23 EER Requirements Specific To: HVAC System 2 : 1. Equipment meets minimum efficiency: Heat Pump: 2.89 COP 9.74 EER Generic Requirements: Must be met by all systems to which the requirement is applicable: • 1. Calculation of heating and cooling loads.Design loads are determined in accordance with the procedures described in the ASHRAE/ACCA Standard 183.Alternatively,design loads have been determined by an approved equivalent computation procedure. ✓ 2. Equipment and system sizing.Heating and cooling equipment and systems capacity do not exceed the loads calculated in accordance with Section 503.2.1. Plans reference page/section: ✓ 3. 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. ✓ 4. 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.

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: ✓ 6. 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. Plans reference page/section: ✓ 7. 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: ✓ 8. Off-hour controls.Each zone is provided with thermostatic setback controls that are controlled by either an automatic time clock or programmable control system. Plans reference page/section: ✓ 9. Shutoff damper controls.Both outdoor air supply and exhaust are equipped with not less than Class I motorized dampers. Plans reference page/section: NA ✓ 10.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: NA ✓ 11.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: NA ✓ 12.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. Plans reference page/section: NA ✓ 13.Ventilation.Ventilation,either natural or mechanical,is provided in accordance with Chapter 4 of the International Mechanical Code. 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. Plans reference page/section: ✓ 14.Demand controlled ventilation(DCV).DCV is required for spaces larger than 500 ft2 for simple systems and spaces larger than 150 ft2 for multiple zone systems. Plans reference page/section: ✓ 15.Kitchen hoods.Kitchen makeup is provided as required by the Oregon Mechanical Specialty Code. Plans reference page/section: ✓ 16.Enclosed parking garage ventilation controls.In Group S-2,enclosed parking garages used for storing or handling automobiles employs automatic carbon monoxide sensing devices. Plans reference page/section: NA ✓ 17Air system balancing.Each supply air outlet and zone terminal device is equipped with means for air balancing in accordance with the requirements of IMC 603.17.Discharge dampers intended to modulate airflow are prohibited on constant volume fans and variable volume fans with motors 10 horsepower. Plans reference page/section: NA ✓ 18.Manuals.The construction documents require that an operating and maintenance manual be provided to the building owner by the mechanical contractor.See long description for specifications. Plans reference page/section: ✓ 19.Allowable fan floor horsepower. Each HVAC system at fan system design conditions does not exceed the allowable fan system motor nameplate hp(Option 1)or fan system bhp(Option 2)as shown and calulated in requirement details.
