   Building Occupancy Schedules
• Initial Findings
   – Summer Schedules: Unchanged
   – Night Schedules: Little to no shutdown
   – Weekend Schedules: Small percentage setback
   – Holiday Schedules: None
   – Snow Days: None
   Building Occupancy Schedules
• Ideal Settings
  – Summer Schedules: Unoccupied all times
  – Night Schedules: 4 pm to 6 am
  – Weekend Schedules: Unoccupied F-M
  – Holiday Schedules: Unoccupied all day
  – Snow Days: Quick override available
• Unoccupied schedules are set back a
  minimum of ten degrees.
   Building Occupancy Schedules


• Potential Savings
  – HVAC on average accounts for 58% of energy
    consumption
                     Rebates
• Types of rebates
  – Lighting
  – HVAC
  – Most all energy efficient equipment upgrades
    (must show energy savings)
                  Rebates
• Offered through utility companies to lower
  energy consumption.
• RECCC’s usually offered from their energy
  provider.
           Total Rebates To Date
