Energy efficient improvements can yield long-term cost savings for your business. Energy-saving tips, like these below, show you simple ways to reduce your business's energy use by making minor changes to your daily operations.
- Perform flexible operations during evening or early morning hours, when the demand for electricity is lowest (and typically costs less).
- Turn off the water cooler during periods of high electrical use, which is from 4 to 8 p.m.
- Request employees to shut off copy machines, coffee makers, and other nonessential equipment at the end of the day.
- Implement "cool café" days when food service only serves cold items such as sandwiches, salads, fruits and vegetables.
- Raise thermostat settings for your air conditioning systems by a few degrees during working hours, and consider raising the thermostat further when your facilities are unoccupied.
- Consider moving operations or production schedules away from the first shift, or starting the first shift earlier in the day, to avoid high electricity demands during peak usage periods.
- Turn off machinery not in use rather than letting it idle.
- If you are planning a facility shutdown, consider scheduling it sometime during the hottest months (July or August).
- To conserve energy, reduce water pressure to minimum safety levels before starting any pumping operations. Also, allow sumps at sewerage pumping stations to remain as full as safely possible before pumping.
- If you have water storage tanks at your facilities, fill them before peak electric demand periods in order to maintain sufficient water pressure in the event of a power outage.
- Consider pre-cooling your facility in the early morning hours, prior to peak demand for electricity.
- Verify that all maintenance has been performed on your air conditioning equipment, including changing the filters.
- If you are considering purchasing a new air conditioning system, evaluate high-efficiency units and consult your local electric company about cash incentive available for owners of highly efficient systems.
- Use drapes or shades to prevent direct sunlight from entering your building.
- Turn off heat-generating office equipment, such as copiers and computers, when not in use - especially when your facilities are unoccupied.
- Turn off every second or third lighting fixture in order to conserve electricity and reduce the need for air conditioning.
- Lower the temperature of your water heater to 120 degrees Fahrenheit, which is adequate for normal use. Also consider turning off your water heater during periods of high electrical use or public appeals for electric curtailment.
Elevators & Escalators
- If your elevators are connected to an alternate power supply, verify the maximum number of elevators that can run without overloading the generator.
- When shedding load, make sure that the air conditioning and ventilation systems for the elevator equipment room are not shut off.
- Check the operation, adequacy and maintenance (e.g., fuel supply, filter, coolant levels) of your emergency generators and battery systems periodically. To identify potential problems before the time of need, test emergency generation under full-load conditions.
- If you decide to obtain on-site backup generation, contact your local Department of Environmental Protection (DEP) for information regarding emissions issues and special provisions.
- Before installing emergency generation, contact us for interconnection requirements.
- Check the nameplate information on your motors and verify that they are rated to operate at your supply voltage. Motors are normally designed to operate between plus-10 percent and minus-10 percent of their normal voltage without shortening life expectancy.
- Consider installing a buck-boost transformer as required to maximize the life expectancy of your motors. This is a worthwhile consideration for normal operating conditions as well as during voltage reductions.
- In the case of a blackout, turn off all your units to prevent large power draws when the power comes back on. Once power is restored, turn on your units one at a time to prevent sudden power surges or unnecessary demand peaks.
