1411.1 General: Equipment shall have a minimum performance at the
specified rating conditions not less than the values shown in Table 14-1
through 14-3. If a nationally recognized certification program exists for a
product covered in Tables 14-1 through 14-3, and it includes provisions for
verification and challenge of equipment efficiency ratings, then the product
shall be listed in the certification program.
1411.2 Rating Conditions: Cooling equipment shall be rated at ARI test
conditions and procedures when available. Where no applicable
procedures exist, data shall be furnished by the equipment manufacturer.
1411.3 Combination Space and Service Water Heating: For

calculated by using ASHRAE Standard 124-1991. Storage water heaters
used in combination space heat and water heat applications shall have
either an Energy FActor (EF) or a CAE of not less than the following:

to the zone is shut off or reduced to a minimum.
Exceptions:
1. Special occupancy, special usage, or code requirements
where deadband controls are not appropriate.
2_ Buildings complying with Section 1141.4, if in the proposed
building energy analysis, heating and cooling thermostat
setpoints are set to the same temperature between 70
degrees F and 75 degrees F inclusive, and assumed to be
constant throughout the year.
