Appendix L L19
7.10.8 Use water-conserving dishwashers.
7.10.9 Install gray water heat recovery.
7.10.10 Use low-fl ow pre-rinse spray nozzle 0.1 L/s (
≤
1.6 gpm).
7.10.11 Install end panels on kitchen hoods to lower exhaust rates.
7.10.12 Use compact fl uorescent lamps (CFL) in exhaust hoods, walk-in coolers, and dining
room fi xtures.
7.10.13 Install plastic strip curtains and automated door closers for a walk-in cooler or freezer.
7.10.14 Install electronically commutated motor for walk-in cooler and freezer evaporator fan.
7.10.15 Use Energy Star–rated deep fat fryers.
7.10.16 Use Energy Star–rated boilerless steamers.
7.10.17 Use high-effi ciency ovens.
7.10.18 Change location and co-location of kitchen equipment to increase local exhaust capture
effi ciency. Position cooking appliances close to the walls and avoid island installations
when possible or place back to back.
7.10.19 Use supply air diffusers that direct air parallel to the hood’s face or downward.
7.10.20 Eliminate gap between kitchen equipment and the back wall.
7.10.21 Calibrate hot water heater temperature setpoint in accordance with the requirements
of the dish machine: typically 60 °C (140 °F) for high-temperature machines and 51.7
°C (125 °F) for low-temperature machines.
7.10.22 Install an automated fl ue damper atop the water heater fl ue.
7.10.23 Install a time clock to shut recirculation pump on the water line during closed hours.
7.10.24 Cascade (transfer) outside air supplied into the dining room to the kitchen space.
7.11 Virtual Training Facilities
7.11.1 Maintain room air temperature within requirements to current generation of equip-
ment and electronics components.
7.11.2 Direct heat stream from the simulator’s condenser unit outside the air-conditioned
space via a duct of a central system, or move condenser units outside air-conditioned
space.
7.11.3 Place power conditioners outside the air conditioned space, and use waste heat for
heating spaces with heating needs.
7.11.4 Vent heated air from the manned module exhaust grilles using a central exhaust system.
In summer, heat stream from the simulator can be directed outside. In winter, warm air
can be directed to spaces with heating needs.
7.11.5 Vent heated air from the computer server exhaust grille using a central exhaust system
connected to exhaust grilles In summer, heat stream from the simulator can be directed
outside. In winter, warm air can be directed to spaces with heating needs.
7.12 Swimming Pool
7.12.1 Cover swimming pool when pool is not in use—e.g., lunch time, after hours—to save
both water and energy (heating, cooling, electrical energy saving). With external pools,
this can save 80% of energy costs.
7.12.2 Check the water temperature (must not be above 27 °C (81 °F).
