Energy recovery ventilation systems. Individual fan systems that have both a design supply air capacity of 5,000 cfm or greater and a minimum outside air supply of 70 percent or greater of the design supply air quantity have an energy recovery system. Exception(s): ❑ Where energy recovery systems are prohibited by the International Mechanical Code. ❑ Systems serving spaces that are not cooled and are heated to less than 60'F. • ❑ Where more than 60 percent of the outdoor heating energy is provided from site-recovered or site solar energy. LI Type 1 kitchen exhaust hoods. ❑ Cooling systems in climates with a 1-percent cooling design wet-bulb temperature less than 64'F(18'C). ❑ Systems requiring dehumidification that employ series-style energy recovery coils wrapped around the cooling coil when the evaporative coil is located upstream of the exhaust air stream. ❑ Systems exhausting toxic,flammable,paint exhaust,corrosive fumes,or dust. Li Laboratory fume hood systems that include qualifying features. Plans reference page/section: /V t Project Title: Mudbay LL work Report date: 08/23/14 Data filename: Untitled.cck Page 1 of 5 I _ 4. Supply air economizers shall be provided on each cooling system and are capable of providing 100-percent outdoor air,even if j_ additional mechanical cooling is required to meet the cooling load of the building.Systems provide a means to relieve excess outdoor air during economizer operation to prevent overpressurizing the building. Exception(s): U Cooling equipment less than 54,000 Btu/hr total cooling capacity. i I Plans reference page/section: r l Generic Requirements: Must be met by all systems to which the requirement is applicable: r 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. j 2. 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: 4,1 3. 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: FA,A.I \a 4. 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. 5. 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: V. I ❑ 6. 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: �'f f { 7. 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): O Thermostats requiring manual change over between heating and cooling modes. Plans reference page/section: ` I \fa 8. 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: Wit 1 9. Off-hour controls. Each zone is provided with thermostatic setback controls that are controlled by either an automatic time clock or ttt��� programmable control system. Exception(s): ❑ 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: (44 I 10.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: (t I Project Title: Mudbay LL work Report date: 08/23/14 Data filename: Untitled.cck Page 2 of 5 j 11.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.
