3. Energy Analysis
— Evaluate Energy Usage: Disaggregation
¡ By Facility Type and Occupancy
¡ Energy Usage Pattern (Hourly, DOW, Month)
¡ Compare Usage in Similar Campus Buildings
— The Key factors
¡ Existing equipment usage
¡ Existing equipment schedules
¡ Existing occupancy schedule
— Develop Energy Usage Index targets by building type
Look for
Mismatch

4. Energy Usage Index (/sqft)
Building Type à Admin Admin Admin Admin Dorm Dorm
Pre Post Pre Post Pre Post
System Type kWh kWh Therm Therm Therm Therm
Steam Heat (No A/C) 1-3 1 70 50 190 110
Hydronic Heat (No A/C) 5-8 4-6 80 45 140 80
Air Distribution Heat (No A/C) 10-12 7-9 80 45 140 90
Hydronic Heat Central A/C 14-18 9-12 80 45 140 90
Air Distribution for Heat with A/C 15-12 12-15 80 45 140 90

5. Evaluate Energy Purchases
— Energy Cost Profile
¡ Electricity – Evaluate rate schedule and how it affects cost
¡ Fuel – What happens over the course of the year?
— Current energy rates
¡ Determine the best applicable energy rate for existing systems
¡ Determine the best rate upon completion of the energy project

6. Reduce and Control Energy Usage

q Heating and Cooling Plant Optimization
q Heating and Cooling Centralized Control (EMS)
q Lighting and Lighting Controls
q Cloud Computing - Data Center Consolidation
Generate New Sources of Localized Energy Production
q Combined Heat and Power
q Wind Turbine
q Solar Thermal and PV
q Ground Source Heat Pump (aka Geothermal Energy)
Occupant Behavioral Awareness and Change
q Kinetic Energy Gym Equipment
q Dormitory Energy Challenges
Pathway to Net Zero
