Ways to Save
- Simple: Monitor, inspect and clean indirect heating systems on a regular basis to ensure efficient operation. Repair system leaks to reduce air infiltration into the heating process, and keep furnace doors closed whenever possible.
- Low cost: Repair leaking steam traps. Complete a boiler tune-up.
- Capital investment: Implement waste-heat recovery to use for preheating, steam generation or water heating. Install furnace pressure controllers to adjust pressure within furnaces. Optimize the ratio of air to fuel with flow metering or fuel-gas analysis to maximize burner efficiency.
- Simple: Reduce the compressed air system pressure to minimize energy consumption while still maintaining compressed air end-user performance. Optimize compressor sequencing for systems with multiple compressors.
- Low cost: Install no-loss condensate drain valves to eliminate compressed air loss when condensate is drained from the system. Replace standard air nozzles with high-efficiency air nozzles to reduce compressed air flow requirements for the process.
- Capital investment: Reduce artificial demand for compressed air by installing a pressure flow controller or regulator. Replace air-powered devices with electric-powered devices, like low-pressure blowers for air cleaning tasks. Duct cooler outdoor air to the compressor to reduce overall energy consumption. Recover waste heat from the compressed air system for space and/or process heating. Install variable-speed compressors and high-efficiency compressed air dryers.
- Simple: Inspect motors on a regular basis for adequate ventilation, non-cracked belts, properly aligned shafts, and secure and quiet bearings. Plus, clean and lubricate appropriately. Review and ensure voltage is the same on all phases of input power.
- Low cost: Run right-size motors primarily in the 65%-100% of load range when possible and utilize controls to minimize motor runtime.
- Capital investment: Upgrade from classic V-belts to a notched or synchronous belt drive, which is a more efficient belt style, and install premium-efficiency motors whenever possible. Another way to save energy is to install variable-frequency drives (VFDs) on motors; this will alter the speed of the motor to reduce electric consumption.
- Simple: Ensure HVAC equipment schedules that control space temperatures and ventilation are optimized based on building occupancy. Change air filters every one to three months or more frequently for areas with heavy particulate load. Clean condenser coils to maximize system efficiency.
- Low cost: Perform annual maintenance on all HVAC equipment.
- Capital investment: Install an energy management system to control building energy flows. Replace older furnaces with new energy-efficient equipment. Ensure proper insulation levels in walls, floors and the roof to lower bills and increase comfort. Install high-volume, low-speed fans in heated spaces to circulate warm air near the ceiling throughout the space. Implement advanced rooftop controls by retrofitting existing packaged rooftop air units to reduce heating, cooling and fan energy usage.
- Simple: Turn lights off when the area is not in use.
- Low cost: Install motion sensors in aisles and other areas where lights would otherwise be left on for extended periods of time with no occupancy. Timers and photo sensors can be used to keep security and outdoor lighting on a schedule to maximize efficiency.
- Capital investment: Upgrade to LEDs to see savings of 50% or more compared to fluorescent, metal halide and high-pressure sodium fixtures! LEDs also have a longer life span resulting in reduced replacement costs, emit less heat thereby reducing the cooling load and eliminate time lost due to lighting warmup periods since they are instant start. Implement a network lighting control system to control the settings for individual lights or groups of fixtures.
