    Steam Trap SurveyCentral Distribution and Building Systems
    • 934 Steam Traps Surveyed across Campus
    • 11. 133 Failed Traps (14% of those surveyed)
    • 12. Steam Traps Tagged and Logged into FME Database
    • 13. Failed Traps = >$200,000 yearly Energy Loss
  • 5
    Steam Trap SurveyCentral Distribution and Building Systems
    • $200,000 Yearly Energy Loss
    • 14. Estimated Total Cost of Survey and Repair: <$60,000
    • 15. ROI in >4 Months from
    Date of Repair
    • Goal is to Keep Campus-wide
    Failure Rate to <3%
    • Next Step is to Survey and
    Evaluate all Campus Steam Traps

    Energy Policy Act (EPACT) of 2005Tax Deductions Assignable to Designers
    • EPA-2005 provides an Assignable Tax Deduction that can be “sold” to Designer for additional scope items or reduction in fees
    • 23. Designer defined as “architect, engineer, contractor, environmental consultant or energy services provider”
    • 24. Tax Deduction based upon energy savings and affected square footage up to $1.80/sf
    • 25. $0.60/sf each for Lighting Systems, HVAC Systems and Building Envelope
    • 26. Proposed Legislation increases credit to $1.00/sf/system
