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

Air Distribution for Heat with A/C 15-12 12-15 80 45 140 90

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

Reduce and Control Energy Usage q  Weatherization and Air Sealing 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
