  commissioned by design engineers and LCPS
  mechanical engineering staff
• All existing systems are monitored and managed
  for the life of the facility
• Energy Performance
• All new facilities are in compliance with ASHRAE
  minimum energy standard 90.1
• All new facilities are controlled by energy
  management systems (EMCS) to optimize HVAC and
  lighting efficiency
• Green Power
• LCPS has accumulated over 21,800,000 in cost
  avoidance since 1993, equating to 121,000 acres
  of trees planted, and ranks LCPS third in the
  nation in energy cost avoidance
