F0107p Energy Conservation
Guidelines
Occupied:
Defined to be the time when an instructional activity and/or an instructional
support activity is being conducted within a particular HVAC Zone as determined
by the manager of the specified HVAC Zone AND the Energy Specialist.
Should the manager of the specified HVAC Zone and the Energy Specialist
not agree as to whether a time is deemed to be “occupied” or not, the matter
shall be resolved by the Vice President of Finance & Operations.
Please direct heating or cooling Comfort Concerns to
http://wire.westerntc.edu/pplant/
HVAC Scheduling will be aligned with room utilization based on room scheduling.
If you need an area heated or cooled please notify
http://wire.westerntc.edu/pplant/
All Staff/Faculty/Board Members/Students & Western Facility
Users Responsibilities:
·
Every person
is expected to be an “energy saver”
as well as an “energy consumer.”
·
The energy consumer is responsible for implementing the guidelines during the
time that he/she is present in the classroom or office.
General Responsibilities:
1.
Doors shall remain closed when HVAC is operating. Ensure doors between
conditioned space and non-conditioned space remain closed at all times (i.e.
between hallways and Western Library).
This is not only an energy concern, but also a safety issue.
2.
All computers should be turned off each night. This includes the monitor, local
printer, and speakers. (Please notify
Energy Education Specialist if remote access is required).
Security & Network equipment is excluded.
3.
All office machines (copy machines, laminating equipment, etc.) shall be
switched off each night and during unoccupied times. Fax machines should remain
on.
4.
All blinds should be closed when leaving a room.
If there are no blinds, or they are not working properly, please contact
http://wire.westerntc.edu/pplant/
5.
Turn off/unplug appliances and office equipment when not in use.
(coffee pots, microwaves, pencil sharpeners, radios, etc)
If you need a power strip please contact
http://wire.westerntc.edu/pplant/

break rooms, hallways and offices).
The only exception is emergency lighting.
3.
Utilize natural lighting when/where appropriate.
Refrain from turning lights on unless definitely needed. (Remember that lights
not only consume electricity, but also give off heat.
This places an additional load on the air conditioning equipment and
thereby increases the use of electricity necessary to cool the room).
