BACKGROUND AND PURPOSE

The Engineering and Energy Management division of the Department of Facilities
Management at the Colorado School of Mines (“Mines” or “the school”) has developed
an Energy Management Policy to help the campus understand:
• Measures being implemented to conserve energy and keep utility costs at a
reasonable level, and
• Ways in which the campus community can help conserve energy and keep utility
costs down.

2.0 DEFINITIONS

The following terms should be understood prior to review of the Energy Management
Policy:

2.1 ASHRAE: American Society of Heating, Refrigeration & Air-Conditioning
Engineers

2.2 Daylighting: The use of natural daylight coming in through windows to light
interior rooms instead of artificial light.

2.3 HVAC: Heating, ventilating and air-conditioning acronym.

2.4 Occupancy Sensor: Local electronic controller that automatically turns off lights
when it senses nobody is in the room.

2.5 Override Timers: Time switches that connect to HVAC programming that allow
for occupants to override air handling equipment “on” during unoccupied times for a
set period of time.

2.6 Set Point: The temperature setting that a thermostat attempts to maintain
through the control of the HVAC equipment.

2.7 Utilities: In this case, utilities refer to electric, natural gas, steam, and water.

2.8 Air Changes Per Hour: Measure for how many times air is replaced within a
defined space.

2.9 Make Up Air: Conditioned and circulated air as part of a heating, ventilating,
and air-conditioning (HVAC) system.

2.10 Process Cooling: A procedure used to cool equipment.

2.11 Supply Diffuser: An air distribution outlet, usually located in the ceiling and
consisting of deflecting vanes discharging supply air in various directions and planes,
and arranged to promote mixing of the supplied air with the air already in the room.

3.0 POLICY

The Department of Facilities Management is responsible for making all decisions and
arrangements related to utilities for the campus. Facilities Management is also
responsible for paying the utilities bills for the entire campus and managing the utility
budget. Facilities Management pays the utility providers for the campus usage in four
main areas: steam, electricity, natural gas, and water. Facilities Management is the
main point of contact for each of these providers. In addition, Facilities Management
functions as the agent for the campus in such areas as rate negotiations, infrastructure
and connection decisions and maintenance, contract negotiations, and billing
management. These responsibilities are included within the mission of Facilities
Management.

In certain cases Facilities Management “bills back” other departments for the energy that
the department or tenant uses. These situations are determined by the Senior Vice
President of Finance and Administration. In most other cases the utility costs are
included with the overhead charges that the departments pay for the use of the facilities.

ENERGY USAGE GUIDELINES

Because of the responsibilities inherent in managing campus utilities, the Engineering
and Energy Management division of Facilities Management has developed guidelines
concerning utilities-related operational aspects of the campus. The purpose of these
guidelines is to conserve energy and utilities, while not placing an undue burden on
campus occupants or causing disruption to the educational and research missions of the
university. These guidelines are as follows:

4.1 Lighting Use

Facilities Management encourages the efficient utilization of lighting in the following
ways:
• Turn off classroom lighting when it is not needed.
• Turn off lighting in offices and classrooms when possible to utilize natural
daylighting.
• Turn off main office lights and use fluorescent task lights, especially in
intermittently occupied common offices (like grad student offices).
• Turn off lights in classrooms, offices, labs, and other areas when leaving.
• Report to Facilities Management through work order system when occupancy
sensors appear to not be working.

• Report other lighting issues to Facilities Management through work order system,
such as exterior lights on during day, lights continually left on during unoccupied
times, field lights on during times when no athletic activities happening, etc.

4.2 Building Occupancy Schedules

Facilities Management strives to make sure HVAC systems are operating when a
significant number of occupants are in buildings. At the same time, Facilities
Management seeks to limit the amount of time HVAC systems are running in
buildings that are not occupied. To this end, Facilities Management is instituting the
following guidelines:

In general, buildings are expected to be occupied between the hours of 6 am
and 9 pm, M-F, during the spring and fall semesters and 6 am and 6 pm, M-F,
during the summer. Facilities Management uses these time frames as a
default guideline only and may shorten or increase hours of operation for some
or all areas of a building after interviewing and consulting with building
occupants.

Facilities Management has the ability to operate certain areas of buildings for
extended hours for special circumstances such as critical research experiments
or special projects. In the event of special circumstances, the appropriate
department head must be notified. Department heads will then notify Facilities
Management of the request. Requests must have a defined timeline and be for
scheduled occupancy. Facilities Management does not want to run buildings
after hours simply for the convenience of someone working or studying during
odd hours. However, Facilities Management will consider such cases for after-
hours temperature setback to avoid unbearable temperature extremes.

Certain large lecture halls are able to be shut down during non-use but will
have operational HVAC whenever the rooms are scheduled through the
Registrar’s office.

Facilities Management is exploring the use of override timers for HVAC in
certain cases.

Contact the Facilities Management main line for after-hours scheduling
requests at 303-273-3330. Procedures for requesting changes to building
temperature scheduling are described here.

4.3 Campus Heating and Cooling Set Points

Facilities Management has defined the following temperature set points at the
recommendation of the Engineering and Energy Management division. These set
points are within recommended ASHRAE limits and correlate well with the set points
implemented by other institutions of higher education around the state and country.

Cooling set point (Occupied)

76 degrees F
Cooling set point (Unoccupied)
Varies on building and use

Heating set point (Occupied)

68 degrees F
Heating set point (Unoccupied)
60 degrees, but can vary by building

These set points are general guidelines but can vary by situation. For example, a lab
experiment may require a certain constant temperature for a set amount of time.
Arrangements can be made for these situations. Please discuss these situations
with the appropriate department head or fill out a Facilities Management work order.

In general, laboratories must be ventilated at a certain minimum air changes per hour
24 hours/day, 7 days/week. The above set points will not interfere with those
requirements.

4.4 Laboratory Use

Facilities Management recommends the following procedures for laboratory users.

Close fume hood sashes when not in use. The amount of air volume that is
used is decreased tremendously when the sash is closed. Heating and cooling
make up air for laboratory exhaust is probably the most expensive energy cost.

The use of domestic water for process cooling is strongly discouraged. It is a
wasteful use of one of our most precious resources. In some cases, this
practice may be allowed for a temporary situation until mechanical process
cooling can be provided.

Turn off laboratory equipment when it is not required.

Consult with Facilities Management when considering purchasing new
equipment. Select the most efficient equipment possible and consider facility
needs. See the Facilities Management Services Policy for information on
purchasing equipment.

Do not leave laboratory doors open to an adjacent corridor. This creates air
balance problems and is against building code.

4.5 Computers and Office Equipment

The following recommendations are being provided for office users.

Turn off office equipment when not in use.

Make sure computer monitor power saving devices are employed. Screen
savers do not save energy.

Turn off monitors and unplug chargers and other types of equipment when
leaving for the day. Facilities Management is working with CCIT to determine
the best policy for shutting off CPUs when not in use.

Consolidate office appliances such as coffee pots and refrigerators into
common ones as much as possible.

Share printers and copiers whenever possible and turn them off at the end of
the day.

4.6 Miscellaneous Energy Saving Guidelines


Utilize blinds to reduce cooling loads.

The use of portable heating devices such as space heaters is strongly
discouraged. These devices are very inefficient and expensive to operate.
Report heating and cooling issues to Facilities Management through the work
order system.

Facilities Management and CCIT are encouraging the consolidation of servers
into the existing data center machine rooms. In general, Facilities
Management does not support cooling of individual data closets dispersed
throughout the campus buildings.

Do not seal off supply diffusers or exhaust vents. This will disrupt the proper
air balance of the system. Report problems to Facilities Management.

Do not try to “trick” thermostats with things like bags of ice, hot cups of water or
wet rags. These techniques don’t work and make problems worse. Report
comfort issues to Facilities Management.

Do not leave windows open when leaving a space, and do not prop doors open
permanently.

Conserve water as much as possible by not leaving water running and taking
shorter showers if using the recreation center or dormitories.

5.0 OPERATIONAL STRATEGY

Mines is committed to bringing a sustainable environment to campus. Facilities
Management is always looking at new technologies and ideas to incorporate into the
campus buildings and grounds. These new strategies are evaluated based on a life
cycle cost analysis point of view and impact to the campus mission. New strategies that
are acceptable will be incorporated into the Facilities Management Campus Standards.
Please contact Facilities Management with any new ideas for energy savings.
