Light Emitting Diodes (LED)

• Municipal Deck Pilot
• 40 energy reduction. 75 of survey respondents
  feel LED level of deck is safer and brighter
  (despite 11 fewer lumens cast)
• New Underground Parking
• 544 fixtures, approx. 100W per fixture savings.
  City projected to save 700k-1M over 15 years on
  energy and maintenance

Light Emitting Diodes (LED)

• Life cycle replacement upgrade of existing
  roadway lighting
• 5 times the lifespan, less than ½ the energy
  demand of Metal Halide
• Motion sensors and timers added to further
  increase energy efficiency

Solar Thermal

• Fire Station 15, solar thermal water heating
  system installation
• The Avery C. Upchurch Municipal Building was
  originally designed with a solar pre heat system
• The storage tank, heat exchanger, solar loop
  pump, domestic water circulator pump and
  controller were recently replaced after over 24
  years of operation

14
Solar LED

• Reduce energy consumption from the grid to zero
• Energy savings/ avoidance are immediate
• Conduit and wire feeder cost savings are most
  apparent at point of installation

15
Water Efficiency

• Installation of lavatory aerators, low flow and
  no flow urinals, reduced flow shower heads, and
  flush valve kits in numerous facilities
• Use of drip irrigation and drought tolerant plant
  material
• Extension of reuse water system by Public
  Utilities is anticipated

16
Energy Awareness Pilot

• Periscope Dashboard
• The Ranking Chart enables user to display
  comparative values for similar variables, ranked
  in either increasing or decreasing order. Values
  may be normalized.
• The Demand Chart enables the display of the
  amount of time a variable is above a specific
  level during the selected interval.

17
Energy Audits

• Facilities and Operations partnership with
  Inspections Department to expedite audits within
  City facilities
• Monitor preventative maintenance program
• Changes Completed
• Motion sensors in hallways restrooms,
  programmable thermostats, retrofit existing light
  fixtures, adjust HVAC set points, delamp
  vending machines

  trash trucks, recycling trucks and dump trucks
  have operated on B20 since 2002
• In October, the City traded in 2 gas powered
  pickup trucks for 2 electric cars
