Western Oklahoma State College 20x2020 Energy Conservation Guidelines

These guidelines are not intended to be all-inclusive, and they may be modified for specific conditions. Within reason, achieving the core mission of the organization by maintaining the comfort of the occupants and functionality of the space takes priority over energy savings. Industry building and safety codes, equipment manufacturers’ specifications concerning temperature and humidity ranges, and any other environmental constraints supersede proposed guidelines.

Responsibilities

1. Every staff member is responsible for implementing the guidelines when they are in their work area and common areas.
2. Energy Managers are responsible for performing routine walkthroughs and communicating walkthrough results to the relevant stakeholders.
3. Operations and maintenance employees are responsible for establishing a schedule for their procedures to meet these guidelines, and health and safety requirements, and for verifying compliance with those procedures.
4. Custodial or other staffs working in the facility after normal operating hours are responsible for ensuring all lighting and relevant equipment is off when they leave.

General

1. Doors between areas that are conditioned and those that are not conditioned shall remain closed at all times, such as between hallways and gym or pool areas.
2. Custodial shifts shall be scheduled during or immediately after regular operating hours to minimize the length of time building systems equipment operates and consumes energy.
3. Where the space is subject to codes or standards on air changes, lighting, or other characteristics, every attempt should be made to meet those standards (and maintain safety, comfort, and productivity) without exceeding the standards more than necessary to avoid wasting energy.
   

   Electronics

4. All office machines and other equipment shall be switched off during unoccupied times. Machines that can be feasibly turned off between uses shall be, and where that is not possible equipment shall be set to go into power saving mode. Exceptions include fax machines and any mission critical equipment that must remain on.
5. All capable computers shall utilize the power management feature’s energy saving mode.
6. All peripheral devices plugged into the CPU, including the monitor, shall be set to go into sleep mode after 10 minutes of inactivity.
7. All chargers for phones, laptops, tablets, and any other electronic device shall be unplugged when not in use or once the device is fully charged. Where available, power strips shall be used in order to make cutting power to multiple devices easier.
8. Personal electronic devices that are not critical to performing job duties should be used as little as possible.
   

   Temperature and Air Systems

9. Occupied temperature settings shall not be set above or below the stated set points unless the area is deemed a critically controlled environment. These set points have been based on ASHRAE 55 and take into consideration that occupant comfort is paramount while maximizing equipment performance. However, the individual building’s properties and any issues of humidity levels must be taken into consideration.
   
    Temperature settings:
    Cooling Season Occupied Set Points: 72°F - 78°F
    Minimally Occupied Set Point: 85°F
    
    Heating Season Occupied Set Points: 68°F - 72°F
    Minimally Occupied Set Point: 55°F
   
   
10. Occupied set points shall be used during normal business hours. Minimally occupied (or unoccupied) set points shall be used outside of normal business hours.
11. A schedule for periods of anomalous activity, such as holidays and large events after hours, shall be established.
12. During unoccupied times, the HVAC equipment shall be set back or turned off, though humidity and other building or environmental constraints should be taken into consideration.
13. Exhaust fans shall only run when needed for thermal control or adequate ventilation. Exhaust fans should be off during unoccupied times.
14. In areas that experience intermittent use, such as the auditorium or conference rooms, HVAC equipment shall be kept in unoccupied mode or off until occupied when possible. The number of people and type of activities should be considered to ensure comfort and humidity management. Pre-conditioning for up to 30 minutes prior to space being occupied is one possible strategy.
    

    Cooling Season Equipment

15. Ceiling fans shall be utilized in all occupied areas where available. Ceiling fans shall be off when the space is unoccupied.
16. Doors between air-conditioned spaces and areas that have evaporative coolers (such as shops or kitchens) shall be kept closed whenever possible to prevent moisture from reentering the conditioned environment.
    

    Heating Season Equipment

17. The unoccupied temperature setting shall be 55°F. This may be adjusted during bouts of extreme weather.
18. The overall system must be balanced to minimize risks of freezing pipes or any other adverse effects.
19. During the spring and fall, when the threat of freezing is low, all steam and forced air heating systems shall be switched off during unoccupied times unless required to maintain a sensitive environment. Hot water heating systems should be switched off using the appropriate loop pumps.
20. A six-degree Fahrenheit dead-band between heating and cooling should be used in areas that have heat pumps.
21. Personal space heaters shall not be used unless a specific accommodation has been approved.
    

    Lighting

22. With the exception of required safety lighting, all offices have been equipped with sensors in the lighting so that unoccupied areas will be turned off.
23. Natural lighting should be used whenever possible.
24. Full lighting should be used only when necessary. Do not turn on all of the lights if only using one portion of the space or only entering the space briefly.
25. Areas that experience intermittent use, such as common areas, shall have lights off until the space is occupied.
26. Custodial staff shall use lighting only in active working areas and use additional lighting for safe passage only. They will also be responsible for shutting off the lighting in their work areas when they leave.
27. All exterior lighting shall be off during daylight hours.
28. Outside of daylight hours, exterior lighting should be optimized to allow for safety and security while minimizing decorative use.
    

    Water

29. Domestic hot water systems shall be set no higher than 120°F (or 140°F for cafeteria service with dishwasher booster).
30. During unoccupied times, all domestic hot water recirculating pumps should be switched off. Considerations should be made for longer unoccupied periods to avoid the water going stagnant.
31. All plumbing and/or intrusion (i.e. roof, window, door, faucets, water fountain) leaks shall be reported and repaired immediately.
32. Grounds watering shall be scheduled to coordinate with the City of Altus watering regulations.
33. Ensure the water does not directly hit the building, sidewalks and parking area when spray irrigating.
34. Coordinate irrigation plans to eliminate grounds watering during or immediately after rain.
35. Consider sweeping parking lots and other outside areas instead of cleaning with a hose regularly.
36. When washing laundry, only run full loads.
37. Where allowable by health and safety codes, wash with the cold or warm setting instead of hot.

YEAR-ROUND ENERGY SAVINGS TIPS

Throughout the year, faculty, staff and students are reminded of the steps they can take to help the university save energy while they are away. Holiday weekends and student breaks provide excellent opportunities for significant energy savings. Here are ways you can help when you will be away for the day or weekend:

• Turn off all computers, monitors, speakers, and printers. If you plan to access your computer remotely, make sure the only thing left on is your computer (CPU).
• Unplug all chargers, fans, coffee pots, candle warmers, TVs, radios and other items that are plugged into an outlet and can be unplugged without damage.
• Before long breaks, clean out small refrigerators, and unplug with door propped open.
• Remove all food waste from your area.
• Close blinds, turn off lights and unplug all seasonal lights.

Please be advised that temperatures in Western’s buildings may be cooler or warmer than usual during holiday weekends and extended breaks.

THANK YOU FOR CONTRIBUTING TO WESTERN’S ENERGY SAVINGS!!!
