20/20 Energy Savings VisionMy ideas to help Enterprise achieve its 20/20 vision encompass the individual

branches use of electricity, natural gas, and water. Energy savings opportunities are listed

below.

Electricity

Lighting

Use compact fluorescent lamps where an incandescent bulb would be used. Thesebulbs used 75% less energy than an incandescent bulb and can last ten times longer.

(United States Environmental Protection Agency, 2007) Dont use a T12 fluorescent lighting system. Use energy-efficient fluorescent lighting

systems. Use T8 and T5 lamps, which are more efficient, provide a high intensity,

and have a longer life. Always use electronic ballasts and not magnetic ballasts,

electronic ballasts are 30% more efficient. (United States Environmental Protection

Agency, 2007)

Make use of lighting controls. A flexible lighting system will increase efficiency ofyour lighting system by letting you control which lights and the intensity of the light

being used. Why light an unused area? Common controls are dimmers, occupancy

sensors, and daylight sensors. An estimated 20-25% energy savings on lighting canbe attained through this (United States Environmental Protection Agency, 2007)

Day lighting is a great technique which requires no additional technology. By usingsunlight you can dim/adjust lighting in the facility throughout the day to save on

electric costs. Methods include; making sure windows arent blocked, uses of

skylights, and daytime dimming systems. Research has shown that daylighting saves

money and increase employee productivity and sales. (United States Environmental

Protection Agency, 2007)

Appliances

Only use Energy Star appliances on any new purchases of equipment.o Energy Star Refrigerators use 15% less energy than non-certified

models. (U.S. Environmental Protection Agency) Refrigerators are a

major appliance and use a lot of energy. Two easy ways to increase its

efficiency are too make there theres an inch or two of space between

the appliance and the wall and avoid putting it in the sun or next to a

heat source.

o Energy Star computer monitors use 25% less energy than non-certified models. (U.S. Environmental Protection Agency)

o Energy Star computers use 30-65% less energy than non-certifiedmodels. (U.S. Environmental Protection Agency)

o Energy Star copy machines use 40-55% less energy than non-certifiedmodels. (U.S. Environmental Protection Agency)

o Energy Star central air conditioners are over 15% more efficient thannon-certified models. (U.S. Environmental Protection Agency)

Natural Gas

Garage

Garage doors to the car wash open and close many times a day. To reduce the loadput on the heating and cooling system install automatic sensors to ensure the doors

close after a vehicle or person exits. Ensure the seals on the door are not hardened

or cracked.

o Educate employees on the energy efficiency value of keeping thedoors sealed.

o For new garage door installations, specify a thermal break of R-10 orgreater.

Building

Buildings account for 41% of annual energy use in the U.S., with space heating and

cooling accounting for the top two uses in the building. (Air Movement and Control

Association Internation, INC., 2010)

Due to the large amounts of foot traffic we get coming in and out of ourbuildings the doors are opened and closed a lot. This results in cool aircoming in or hot air being lost outside. To help alleviate this installation of air

curtains or vestibule doors will reduce the amount of cooling and heating

that is lost.

Many commercial buildings feature vestibules, which are small areasseparated by two sets of doors. Vestibules use a small air space to improve

occupant comfort and reduce drafts by separating the outside from the inside

of the building. They also save energy. For new construction or major

renovations, vestibules are a good idea and should be considered for existing

buildings as part of major renovation of the faade. (Published by the

National Automobile Dealers Association, 2016)

Use a programmable thermostat to reduce the amount of heating/coolingused when the building is unoccupied. By turning your thermostat back 10

to 15 for 8 hours, you can save 5% to 15% a year on your heating bill -- a

savings of as much as 1% for each degree if the setback period is eight hours

long. In the summer, you can follow the same strategy with central air

conditioning by keeping your house building warmer than normal when you

are away, and lowering the thermostat setting to 78F (26C) only when you

are in the building and need cooling.(U.S. Department of Energy, 2013)

Window orientation is important to a buildings energy budget. Minimizenorth facing window area and maximize south facing windows to help reduceheating costs in the cooler months. Shades and over hangs will help reduce

the solar inputs from these windows in the warmer months.

Use Energy Star qualified windows with a U-Factor of 0.35 or lesso U-Factormeasures the rate of heat transfer and tells you how well the

window insulates. U-factor values generally range from 0.25 to 1.25

and are measured in Btu/hftF. The lower the U-factor, the better

the window insulates. (Energy Star)

Install weather stripping on doors and windows to reduce any air leaks. Itsan easy and cost-effective way to save on heating and cooling costs. Alsoensure existing weather stripping isnt hardened or cracked.(U.S.

Department of Energy, 2012)

Water

Restrooms

Toilets on average use about 1.6 gallons per flush, while urinals on averageuse about 1.0 gallons per flush. Having a urinal available could save a

moderate amount of water. (U.S. Department of Energy, 2016)

Install WaterSense labeled faucets and fixtures which can use up to 20percent less water than standard models. (U.S. Environmental Protection

Agency, 2012)

Carwash

Choose hand-held spray wands and foamy brushes that use 3.5 gallons perminute or less.

Make sure each spray wand, foamy brush, or similar system has a positiveshutoff valve so that the water will not run while the system is not being

used.

Replace spray nozzles regularly and check for leaks.o Repair the leaks promptly as they occur. Leaks can account for up to

10% of water use. (California Urban Water Conservation Council,

2000)
