 LEED: The Future is Now
• The most recent version of LEED requires
  a minimum of 8% up to a maximum of
  48% total building energy savings over
  ASHRAE 90.1-2007

• For the roof to contribute its “fair share” to
  the energy savings, R-values must be
  increased above ASHRAE 90.1-2007

 Commercial Building Tax Deduction
• Part of 2008 Energy Extension & Improvement Act
• Applies to new or existing buildings
• Available through 2013
• A total $1.80 tax deduction may be divided between partial
  deductions for:
     – Lighting systems: $0.60 / sq. ft.
     – Heating & cooling systems: $0.60 / sq. ft.
     – Building envelope: $0.60 / sq. ft.
• The deduction is available for private and public projects:
     – Private Project: The building owner may receive the deduction
     – Public Project: The building designer may receive the deduction (1)

                                                             (1) IRS Notice 2008-40
             Building Envelope Partial Tax Deduction
How the Building Envelope Deduction Works
•   A $0.60 per square foot deduction is available for building envelope
    improvements only: Roof, walls, doors, windows
•   In order to qualify, the building envelope must be upgraded to provide a
    minimum 20% reduction over ASHRAE 90.1-2001 in the combined usage of
    the building’s heating, cooling, ventilation, hot water, and interior lighting
•   Energy calculations must be performed and certified by a design professional
    using approved energy software(2)
•   The deduction must be taken in the year the building or the energy
    improvement is placed in service
•   Roof insulation and reflective roof surfaces may be used in part
    to achieve the 20% reduction

   High R Business Strategies
• Recommend “LEED-equivalent” R-values that
  achieve LEED savings targets for customers looking
  to “go green”

• Provide an energy analysis with every roofing quote
  using the NRCA “EnergyWise” Online Roof

• Look for local partners to develop building envelope
  solutions eligible for the Commercial Building Tax

Storm Water and Combined Sewer Overflows
                                Storm Water Runoff

            Combined Sewer Overflows

        Combined sewer system are remnants of the country's early
        infrastructure and so are typically found in older communities.
        Combined sewer systems serve roughly 772 communities
        containing about 40 million people.
