5. Optimize system start-up times.
6. Shut off outdoor air quantity.
7. Reduce outdoor air quantity.
8. Reduce system air volume.
9. Reduce air duct leakage.
10. Check and adjust outdoor air dampers for tight closure.
11. Replace dampers with higher quality ones whenever possible.
12. When balancing or rebalancing a system, consider outdoor air leakage when making minimum indoor air settings.
13. Adjust dampers in mixing boxes and multizone units so that they shut off tight to reduce leakage.
14. Avoid use of preheat coils if possible.
15. Raise the mixed air temperature.
16. Reset hot and cold deck temperatures in direction of reduced heating and cooling.
17. Set reheat schedule as low as can be tolerated.
18. Reset chilled water and heating water temperature in accordance with loads.
19. Use lowest possible radiation temperature in perimeter spaces.
20. Do not permit perimeter and interior systems to buck one another.
21. Optimize multiple chiller operation.
22. Run heating and cooling system auxiliaries only when they are required.
23. Whenever possible, only operate return air fans for heating during unoccupied hours.
24. Install auxiliary air risers to reduce fan horsepower.
25. Convert constant volume fan system to VAV operation.
26. Reduce heating in unoccupied areas.
27. Reduce heating in overheated spaces. Do not open the window to cool these areas!
28. Shut off exhaust fans during unoccupied cycles.
29. Check exhaust air quantities from toilet rooms, laboratories, etc. when feasible.
30. Reduce exhaust air quantities from these rooms whenever possible.
31. Convert toilet room exhaust fans to operate only when room is occupied.
32. Reduce supply temperature of domestic hot water systems.
33. Use condenser water to preheat domestic hot water.
34. Use condenser water for air conditioning reheat.
35. Retrofit solar collector to the building to preheat domestic and process water.
36. Install heat recovery devices to reclaim heat from building, kitchen, and process exhaust.

1. Study plant heating and air-conditioning systems to determine if they are of correct design. Many are not.
2. Reschedule operations, whenever possible, to 2nd and 3rd shift to get them off of the 10 AM - 2 PM peak electric demand period.
3. Plan work so that the whole plant can be shut down on given weekends.
4. Shut off machinery when not in use during relief periods, lunch, end of shift, etc.
5. Keep covers on tanks and vats closed to reduce evaporation losses.
6. Use push-pull ventilation on open-surface tanks. 50% or more of the air can be saved.
7. Use immersion heaters whenever possible.
8. Use cold water detergent in washers whenever possible.
9. Combine operations, where possible, to reduce the number of washers.
10. Shroud openings, where possible, to reduce the number of washers.
11. Eliminate stratification of air in the plant during the winter thereby warming the floor. This can easily be done with fans (high) down ducts terminating close to the floor.
12. Use spot heating or cooling of people when they are located far apart.
13. Use evaporative cooling for human cooling whenever practical.
14. Determine whether pressure blowers could replace some compressed air usage.
15. Do not use compressed air at higher pressures than required.
16. Do not permit compressed air to be used for "people" cooling.

18. Use low volume, high velocity exhaust systems whenever possible, such as: ventilated welding guns, hoods for portable grinding equipment, local traveling hoods for molten metal pouring.
19. Analyze all solid waste to determine whether it can be recycled, burned, or composted.
20. Salvage all oil used in the plant. It can either be re-used by refining it or it can be burned in the boilers.
21. If exhaust air is contaminated, evaluate air cleaning devices to determine if the air could be cleaned and recycled.
22. Determine feasibility of utilizing the energy in production operations before exhausting it.
23. Analyze interplant truck runs. Consolidate loads and eliminate trips.
24. Shut off interplant truck engines when not in use.
25. Shut off fork lift engines when not in use.
26. Replace worn out machinery with modern, efficient equipment.
27. Keep heat and smoke relief vents closed during the winter.
28. Consider using waste water for roof sprays during the summer to reduce heat load on the plant.
29. Use automatic regulators to control the volume of water used.
