KitchensEnergy use in restaurants and industrial kitchens can be divided into 5 categories,

and energy is consumed in those areas in these proportions:

The energy used for “food prep” is natural gas, while the other 4 activities use electricity.

Kitchens: Weekday

• Total energy peaks at the lunch rush, and dies back down when food is no longer served

• Food prep, HVAC, and Sanitation are the most variable, and high energy consumers.

Kitchens: Weekend

• Energy usage is much lower on the weekends than during the week.• Peaks still occur at traditional meal times, but they aren’t as high.

Use national averages by building type to estimate carbon associated with activities in the DUC

Conclusions

Recommendations

• Office Electricity Reduction– Turn off monitors if leaving for more than 15 minutes– Turn off computers overnight if possible– Use laptops for tasks not needing a desktop– Unplug all equipment overnight– Turn off lights when leaving the room
