TABLE 8. ENERGY WASTE AND INEFFICIENCY IN PROCESSES (Continued)
Problem description
Waste/
ineffi ciency
Reference/
appendix
Catering High-fl ow prerinse spray nozzles use large volumes of water to rinse soiled
wares
Waste D7.10.1
Using incandescent lighting in exhaust hoods, walk-in coolers, and even din-
ing rooms instead of compact fl uorescent lighting
Ineffi ciency D7.10.2
Increased refrigeration energy use due to open and unprotected freezer
doors
Waste D7.10.3
Ineffi cient walk-in cooler and freezer evaporator fan motors Ineffi ciency D7.10.4
Unnecessary use of refrigerator and freezer antisweat door heater Waste D7.10.5
Ineffi cient deep fat fryer Ineffi ciency D7.10.6
Ineffi cient steamer Ineffi ciency D7.10.7
Ineffi cient ovens Ineffi ciency D7.10.8
Poor exhaust hood design results in heat, grease, and smoke/vapor spillage
or in increased exhaust and make-up airfl ow rates
Ineffi ciency D7.10.9
Single island canopy hood over kitchen equipment Ineffi ciency D7.10.10
Supply air jet disturbs airfl ow around the kitchen hood, resulting in heat,
grease and smoke/vapor spillage
Ineffi ciency D7.10.11
Ineffi cient positioning of appliances at the wall results in heat, grease, and
smoke/vapor spillage or increase exhaust and make-up airfl ow rates
Ineffi ciency D7.10.12
Unnecessarily high hot water temperature setpoint Waste D7.10.13
Heat escapes from the hot water storage tank through the water heater fl ue Waste D7.10.14
Introduction of cool water into water heater from recirculation line results in
heating energy waste when facility is not operating
Waste D7.10.15
Virtual
training
facilities Unnecessary low room air temperature, resulting in discomfort, energy waste,
and condensation on cold surfaces = mold in these spaces
Waste D7.11.1
Simulation equipment is conditioned using DX units connected to training
modules; DX condensers reject heat in the air-conditioned space
Waste D7.11.2
Power conditioners are installed in and reject heat into the air-conditioned
space, increasing cooling load
Waste D7.11.3
Simulator-manned modules reject heat into the air-conditioned bay, increas-
ing cooling load on air-conditioning system
Waste D7.11.4
Computer server rejects heat into the air-conditioned space, increasing cool-
ing load on air-conditioning system
Waste D7.11.5
