Sec. 14.26.03.05. Minimum Efficiency Standards

A. On or after the date specified in Regulation .06 of this chapter, a person may not sell or install a listed product that does not meet or exceed the minimum efficiency standards listed in this regulation.

B. Unit heaters shall be equipped with an intermittent ignition device and shall have either power venting or an automatic flue damper.

C. The efficiency of all low-voltage dry-type distribution transformers may not be less than the values shown in table 4-2 of National Electrical Manufacturers Association Standard TP-1-2002.

D. Commercial refrigeration cabinets shall meet the requirements shown in the following table:

Equipment Type	Maximum Daily Energy Consumption (kilowatt hours)
Reach-in cabinets, pass-through cabinets, and roll-in or roll-through cabinets that are refrigerators with solid doors	0.125V + 2.76
Reach-in cabinets, pass-through cabinets, and roll-in or roll-through cabinets that are refrigerators with transparent doors	0.172V + 4.77
Reach-in cabinets, pass-through cabinets, and roll-in or roll-through cabinets that are freezers with solid doors	0.398V + 2.28
Reach-in cabinets, pass-through cabinets, and roll-in or roll-through cabinets that are freezers with transparent doors	0.940V + 5.10
Reach-in cabinets that are refrigerator-freezers With solid doors	0.273AV + 1.65
Where: V = total volume in cubic feet; and AV = adjusted volume, which is the sum of the volume of refrigerated space, and 1.63 times the volume of freezer space.

E. Large packaged air-conditioning equipment shall meet the Tier II requirements of the "minimum equipment efficiencies for unitary commercial air conditioners" or "minimum equipment efficiencies for heat pumps", as appropriate, developed by the Consortium for Energy Efficiency, Boston, Massachusetts, as in effect on January 1, 2002.
