Certification by Manufacturers. Any spaceconditioning equipment listed in this section may be installed only if the manufacturer has certified to the Commission that the equipment complies with all the applicable requirements of this section.
Equipment shall meet the applicable efficiency requirements in TABLE 110.2A through TABLE 110.2N subject to the following:
1. If more than one efficiency standard is listed for any equipment in TABLE 110.2A through TABLE 110.2N, the equipment shall meet all the applicable standards that are listed; and
2. If more than one test method is listed in TABLE 110.2A through TABLE 110.2N, the equipment shall comply with the applicable efficiency standard when tested with each listed test method; and
3. Where equipment serves more than one function, it shall comply with the efficiency standards applicable to each function; and
4. Where a requirement is for equipment rated at its "maximum rated capacity" or "minimum rated capacity," the capacity shall be as provided for and allowed by the controls, during steadystate operation.
EXCEPTION 1 to Section 110.2(a): Watercooled centrifugal waterchilling packages that are not designed for operation at ANSI/AHRI Standard 550/590 test conditions of 44°F leaving chilled water temperature and 85°F entering condenser water temperature with 3 gallons per minute per ton condenser water flow shall have a maximum full load kW/ton and NPLV ratings adjusted using the following equation:
Adjusted maximum fullload kW/ton rating = (fullload kW/ton from TABLE 110.2D) / Kadj
Adjusted maximum NPLV rating = (IPLV from TABLE 110.2D) / Kadj
Where:
Kadj = (A) × (B)
A = 0.00000014592 × (LIFT)^{4} – 0.0000346496 × (LIFT)^{3}+0.00314196 × (LIFT)^{2} – 0.147199 × (LIFT) + 3.9302
LIFT = LvgCond – LvgEvap (°F)
LvgCond = Fullload leaving condenser fluid temperature (°F)
LvgEvap = Fullload leaving evaporator fluid temperature (°F)
B = (0.0015 × LvgEvap) + 0.934
The adjusted fullload and NPLV values are only applicable for centrifugal chillers meeting all of the following fullload design ranges:
• Minimum Leaving Evaporator Fluid Temperature: 36°F
• Maximum Leaving Condenser Fluid Temperature: 115°F
• LIFT ≥ 20°F and ≤ 80°F
Centrifugal chillers designed to operate outside of these ranges are not covered by this exception.
EXCEPTION 2 to Section 110.2(a): Positive displacement (aircooled and watercooled) chillers with a leaving evaporator fluid temperature higher than 32°F shall show compliance with TABLE 110.2D when tested or certified with water at standard rating conditions, per the referenced test procedure.
EXCEPTION 3 to Section 110.2(a): Equipment primarily serving refrigerated warehouses or commercial refrigeration.
Heat pumps with supplementary electric resistance heaters shall have controls:
1. That prevent supplementary heater operation when the heating load can be met by the heat pump alone; and
2. In which the cuton temperature for compression heating is higher than the cuton temperature for supplementary heating, and the cutoff temperature for compression heating is higher than the cutoff temperature for supplementary heating.
EXCEPTION 1 to Section 110.2(b): The controls may allow supplementary heater operation during:
A. Defrost; and
B. Transient periods such as startups and following room thermostat setpoint advance, if the controls provide preferential rate control, intelligent recovery, staging, ramping or another control mechanism designed to preclude the unnecessary operation of supplementary heating.
EXCEPTION 2 to Section 110.2(b): Room airconditioner heat pumps.
All heating or cooling systems not controlled by a central energy management control system (EMCS) shall have a setback thermostat.
1. Setback Capabilities. All thermostats shall have a clock mechanism that allows the building occupant to program the temperature setpoints for at least four periods within 24 hours. Thermostats for heat pumps shall meet the requirements of Section 110.2(b).
EXCEPTION to Section 110.2(c): Gravity gas wall heaters, gravity floor heaters, gravity room heaters, noncentral electric heaters, fireplaces or decorative gas appliances, wood stoves, room air conditioners, and room airconditioner heat pumps.
Gasfired and oilfired forced air furnaces with input ratings ≥ 225,000 Btu/hr shall also have an intermittent ignition or interrupted device (IID), and have either power venting or a flue damper. A vent damper is an acceptable alternative to a flue damper for furnaces where combustion air is drawn from the conditioned space. All furnaces with input ratings ≥ 225,000 Btu/hr, including electric furnaces, that are not located within the conditioned space shall have jacket losses not exceeding 0.75 percent of the input rating.
All open and closed cooling tower installations shall comply with the following:
1. Be equipped with Conductivity or Flowbased Controls that maximize cycles of concentration based on local water quality conditions. Controls shall automate system bleed and chemical feed based on conductivity, or in proportion to metered makeup volume, metered bleed volume, recirculating pump run time, or bleed time. Conductivity controllers shall be installed in accordance with manufacturer’s specifications in order to maximize accuracy.
2. Documentation of Maximum Achievable Cycles of Concentration. Building owners shall document the maximum cycles of concentration based on local water supply as reported annually by the local water supplier, and using the calculator approved by the Energy Commission. The calculator is intended to determine maximum cycles based on a Langelier Saturation Index (LSI) of 2.5 or less. Building owner shall document maximum cycles of concentration on the mechanical compliance form which shall be reviewed and signed by the Professional Engineer (P.E.) of Record.
3. Be equipped with a Flow Meter with an analog output for flow either hardwired or available through a gateway on the makeup water line.
4. Be equipped with an Overflow Alarm to prevent overflow of the sump in case of makeup water valve failure. Overflow alarm shall send an audible signal or provide an alert via the Energy Management Control System to the tower operator in case of sump overflow.
5. Be equipped with Efficient Drift Eliminators that achieve drift reduction to 0.002 percent of the circulated water volume for counterflow towers and 0.005 percent for crossflow towers.
EXCEPTION to Section 110.2(e): Open and closed circuit cooling towers with rated capacity < 150 tons.
To qualify as a low leakage airhandling unit for use for meeting the requirements for applicable low leakage airhandling unit compliance credit(s) available in the performance standards set forth in Sections 150.1(b) and 140.1, the manufacturer shall certify to the Energy Commission that the airhandling unit meets the specifications in Reference Joint Appendix JA9.

Units must also include an interrupted or intermittent ignition device (IID), have jacket losses not exceeding 0.75% of the input rating, and have either power venting or a flue damper. A vent damper is an acceptable alternative to a flue damper for those furnaces where combustion air is drawn from the conditioned space. e Ec= combustion efficiency (100% less flue losses). See test procedure for detailed discussion. f As of August 8, 2008, according to the Energy Policy Act of 2005, units must also include interrupted or intermittent ignition device (IID) and have either power venting or an automatic flue damper.

a. Coolingonly rating conditions are standard rating conditions defined in AHRI550/590, Table 1. b. Heating fullload rating conditions are at rating conditions defined in AHRI550/590, Table1. c. For watercooled heat recovery chillers that have capabilities for heat rejection to a heat recovery condenser and a tower condenser, the COP applies to operation at full load with 100% heat recovery (no tower rejection). Units that only have capabilities for partial heat recovery shall meet the requirements of TABLE 110.2D d. Outdoor air entering drybulb (db) temperature and wetbulb (wb) temperature. e.
