| While a lighting or refrigeration upgrade is one of the most cost-effective steps you can take to save energy, boost your cash flow, and improve the look of your business, there are many other simple steps you can take in your facility to help reduce energy costs even more. These measures require little or no investment on your part, and can reap great energy benefits. So make sure you aren’t throwing money down the drain, out the window, through cracks in your ducts…and so on.
Consider implementing
these simple changes:
NO-COST MEASURES
Lighting
-
Turn off lights in unoccupied areas, when not in use, or when windows supply sufficient daylighting. Examples include break rooms, storage rooms, walk-in refrigerators and freezers.
- Make sure lighting controllers (time clocks, occupancy sensors and photocells) are set and working properly.
- Make sure exterior lights are off during the daytime.
HVAC
-
Do not block air flow to HVAC vents to allow system to operate efficiently.
-
Keep windows and doors closed while HVAC system is running. Set thermostat to 68 degrees (heating) and 78 degrees (cooling) when occupied.
Refrigeration
-
Clean dirty condenser coils.
-
Allow air flow around coils so that waste heat can dissipate; shield coils from the sun.
-
Keep refrigerators loaded to reduce cycling; gallon jugs filled with water can serve this purpose well.
Office equipment
- Turn off equipment such as computers, monitors, copy machines, and printers when not in use, including each night and on weekends. Make sure to turn off desk lamps, coffee machines and desk fans too.
- Check cubicles to make sure “personal” heaters are turned off – these small heaters are often left on by accident, and surprisingly, represent a significant winter electric load in office buildings.
Shades and Blinds
- In winter, open shades and blinds during daylight hours. In summer, close shades during daylight hours in areas that experience heat buildup.
LOW-COST MEASURES
Lighting
- Replace incandescent lighting with Energy Star®-labeled
compact fluorescent lamps
(CFLs).
- Replace incandescent exit sign lamps with light-emitting
diode (LED) or T1 cold cathode fluorescent (CCFL) exit sign
lamps.
- Reduce general overhead lighting by de-lamping, and use
task lighting where needed. Lighting can be reduced more
near windows.
- Replace any incandescent or halogen torchiéres
with Energy Star® CFL
torchiéres.
- Install occupancy sensors in non-essential
lighting areas.
- When standard halogen bulbs fail, replace with halogen
infrared (HIR) that use 30% less energy.
- When purchasing
task lighting, buy lamps that use CFLs. If you already
have halogen task lamps, when a bulb fails replace it
with a halogen infrared (HIR) bulb.
HVAC
-
Perform regular scheduled maintenance on units, including cleaning burners and air conditioner coils, cleaning and replacing air filters regularly, and checking ducts for leaks and pipe insulation for damage. Have your HVAC service person check the coolant charge, since an incorrect charge can make the unit work harder (and use more energy) to cool your air.
- Install an Energy Star®-labeled programmable thermostat,
with a locking cover to prevent tampering.
- Replace HVAC air filters at least every three months.
Weatherization
- Make sure windows and doors are closing properly, maintain
tight seals and remain closed. Add weatherstripping to doorways
to reduce leakage and drafts.
- Insulate hot water lines where possible, especially in
unconditioned spaces.
RESTAURANTS: NO-COST MEASURES
- Be systematic about startup and shutdown of your appliances
and cooking equipment.
- Reduce dishwasher usage: fully load the washer and turn
off tank heaters when not in use.
- Turn off all fans when the building is unoccupied.
- Turn off exhaust hoods when the appliances under them
are off.
- Maintain evaporative coolers—fan pumps and pads.
RESTAURANTS: LOW-COST
MEASURES
- Install high-efficiency pre-rinse spray nozzles at dish
wash stations to reduce water and natural gas usage.
- Maintain refrigerator doors by aligning them, replacing
worn gaskets, enabling auto door-closers. Replace damaged
strip curtains where present.
- Insulate refrigerant lines where possible.
- Install low-temperature occupancy sensors in walk-in
refrigerators, to save on lighting costs.
- Remember to buy Energy-Star® and other high-efficiency
equipment when replacing old appliances—the incremental
cost is usually minor, and rebates are often available!
LIGHT INDUSTRIAL: NO-COST MEASURES
- Turn off compressed air systems when not in use—especially
nights and weekends.
- Do not use compressed air for cleaning; use blowers or
sweep instead.
LIGHT INDUSTRIAL: LOW-COST
MEASURES
- Distribute heating and cooling loads by installing ductwork
to each machine or station, rather than conditioning large
open spaces.
SCHOOLS: NO-COST MEASURES
- Organize after-school activities for outdoors or to utilize
as few heating/cooling zones as possible so that HVAC systems
can be turned off.
SCHOOLS: LOW-COST
MEASURES
- Organize student activities to look at energy conservation
opportunities and to track the school’s energy performance.
