How Facilities Can Help

Commitment by facilities director

Facilities energy committee

Energy officer position

Include conservation commitment in:

Strategic planning

Mission & vision statement

Staff evaluations

Green campus office within facilities

Energy Awareness

Change campus culture

Be realistic

Active vs. passive

Different strokes for different folks

Seize moral high ground

Temperature control is critical

Develop a multi-faceted campaign

Types of Energy Policies

Heating and cooling temps

Fan run times

Dehumidification (reheats)

Humidification

New construction

Space heaters

Dorm refrigerators

Focus on Energy Pigs

Buildings with:

Labs, kitchens, pools

Buildings with:

100% outside air ventilation systems

Summer and winter heating requirements

Simultaneous heating and cooling

Constant volume terminal reheat HVAC systems

24/7 operation

Electric heating

No offense to pigs intended

Student Projects campus as learning lab

Environmental audits

Campus dumpster dives

Vending machine study

Passive cooling project

Biomass cogeneration

Solar hot water

Energy Conservation 101

Avoid it (best but not always possible)

• Turn it off

• Turn or slow it down

• Use a more efficient source

Low Cost/No Cost Strategies

• Energy awareness (Students, Faculty & Staff)

• Energy conservation competitions

• Green computing & plug loads

• Optimize Controls (EMS)

• Better temperature control

• Minimize summer dehumidification and winter humidification

• Fume hood decommissioning

• Curtailments

• Consolidating Occupancy

• Retro-commissioning

Best Retrofit Investments

Lighting hardware & controls

Variable Speed Drives & Occupancy controls

Energy source optimization

Retro Cx – AHU & Pumping systems

Training

Energy Reduction Strategies – Occupancy BasedMotion sensors – lighting + room HVAC

Night setback with override

Morning warm up, optimal start

Issues with heat pump systems

Demand controlled ventilation (CO2)

Lg. zones w/ variable occupancy

Fan slowdown + flow reduction per schedule
