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
