Definitions
Commercial convection ovens are the most widely used appliances in the foodservice
industry. These are the workhorses of the commercial kitchen, with a wide variety of
uses from baking and roasting to warming and reheating. In addition to traditional uses,
convection ovens are used for nearly all types of food preparation, including foods
typically prepared using other types of appliances (e.g., griddles, fryers, etc.).
Commercial ovens that have earned the ENERGY STAR are about 20 percent more
energy efficient than standard models.
Full- and half-size electric convection ovens, and full-size gas convection ovens can
earn the ENERGY STAR by meeting minimum cooking energy efficiency, as well as a
maximum idle energy rates. Cooking energy efficiency represents the amount of energy
absorbed by the food product compared to the total energy used by the oven during the
cooking process. The idle energy rate represents the energy used by the oven while it is
maintaining or holding at a stabilized temperature.
Standard gas convection ovens have a 30 percent cooking energy efficiency and an
idle energy rate of 18,000 Btu/h, whereas ENERGY STAR certified gas convection
ovens must meet the specification requirements of 44 percent cooking energy efficiency
and idle energy rate of 13,000 Btu/h. Standard electric convection ovens have a 65
percent cooking energy efficiency and an idle energy rate of 2 kW; whereas ENERGY
