Cool Metal Roofing and Energy Star
Why Is Cool Metal Roofing Important?
The U.S. Energy Forecast
The US primary energy consumption is expected
to grow 1.1% annually
Source: Energy Information Administration (EIA)
Our nation’s electricity demands will be 45% greater than today
Source: Nuclear Energy Institute
By The Year 2030
Energy Codes• Reduce Energy Consumption
• Reduce Utility Expenses
• Reduce Environmental Emissions
• Improve Thermal Comfort
• Extend Natural Resources
Since 1989 energy codes have increased stringency
by 23%
Conservation and Efficiency“The cheapest, most reliable source of new energy is saved energy.”
Peter Turnbull, PG&E
New Residential Rebate Program • Reflective Roof component of FPL’s Residential Building
Envelope Program• Presently: rebate of $0.10/ft2
– Min. TSR of 0.65 for metal roofingMin. TSR of 0.65 for metal roofing– Min. TSR of 0.73 for tile roofing
• Future: Flat incentive as of November 1, 2006– $325 to customer purchasing qualified roof, and– $200 to contractor selling qualified roof
• Spring 2007– Adding $0.50/ft2 incentive for residential condominium roofs
• White membranes or white coatings with min TSR of 0.73
Note: Only roofing materials listed on Energy Star website or CRRC directory are eligible for FPL rebates

Heat Island Effect: Roofing (1 Point)“Use roofing materials having a Solar Reflectance Index (SRI)
equal to or greater than the values in the table below for a minimum of 75% of the roof surface.”

What is Energy Star ???ENERGY STAR is a joint program of
the U.S. Environmental Protection Agency and the U.S. Department of Energy helping us all save money
and protect the environment through energy efficient products
and practices.
Qualifying Requirements – Low Slope
• Low Slope: Surface with a slope of 2:12 or less– Initial Solar Reflectance of:
• Greater or Equal to 65%
– Maintenance of SR: (three year reading)• greater than or equal to 50% (-15% SR over 3 years) under normal
conditions.
– Thermal Emittance: • Greater than or equal to 75%.
– SRI Alternative: to be used if the roof product cannot achieve thermal emittance value:
• Initial SRI equal to or greater to 75– Maintenance of SRI: equal to greater to 53
Qualifying Requirements – Steep Slope
• Steep Slope: Surface with a slope of 2:12 or greater– Initial Solar Reflectance of:
• Greater or Equal to 25%
– Maintenance of SR: (three year reading)• greater than or equal to 15% (-10% SR over 3 years) under
normal conditions.
– Thermal Emittance: • Greater than or equal to 75%.
– SRI Alternative: to be used if the roof product cannot achieve thermal emittance value:
• Initial SRI equal to or greater to 18– Maintenance of SRI: equal to greater to 4

Tax Incentives
Energy Policy Act of 2005Tax Credits and Deductions
• Residential– Tax credits up to $500 for home improvements
(homeowners)– Tax credits up to $2000 for new home energy
efficiency (contractors)
• Commercial– Tax deductions up to $1.80/ft2 for energy efficient
building (building owners)
• For taxable years 2006 and 2007
Tax credits – Existing Homes
• All ENERGY STAR® labeled metal roofs qualify for the $500 tax credit
• Must be expected to last 5 years OR have a 2 year warranty
• Installation costs are not included • Manufacturer’s Certification Statement is required
– For tax purposes, save your receipt and the Manufacturer's Certification Statement
– The IRS encourages manufacturers to provide these Certifications on their website to facilitate identification of qualified products
– Homeowner does not have to submit a copy with tax returns
Tax Credits are More Valuable Than Tax Deductions
• Tax credits reduce amount of tax owed dollar for dollar • Tax deduction merely reduces amount of income subject to tax
Example: $500 tax credit saves a person $500 in taxes$500 tax deduction saves a person $140 in taxes
$2000 tax credit saves a person $2000 in taxes $2000 tax deduction saves a person $560 in taxes
Possible Extension To EP Act of 2005
Bill introduced to Senate in June 2006 by Sen. Olympia Snowe (R) ME and
Sen. Dianne Feinstein (D) CA
“EXTEND the Energy Efficiency Incentives Act of 2006”
S.3628
Provisions• Extend tax credits/deductions through 2010• Incentives based on performance rather than cost• Sliding scale for home improvements
– Tax credits from $800 (20% savings) to $2000 (50% savings)
• Increases commercial tax deductions from $1.80 to $2.25 / ft2 for energy efficiency
• Includes “asphalt roof with cooling granules” in addition to cool metal roofing
Key Definitions• TSR / Total Solar Reflectance: amount of radiant energy reflected by a roofing
material. Range is from 0 (total absorption and/or transmission) to 1.0 (total reflection).
• Thermal Emittance: the ability of a material to release heat that it has absorbed. Range is from 0 to 1.0. The higher the emittance the better
• Production Line Color: “Standard color offerings by the manufacturer and are promoted in general product information and in marketing materials”
• Custom Color: A Custom Color is not individually promoted in general product information and marketing materials.
• Color Families: 18 specific color space ranges designed by the CMRC to allow Licensed Sellers with large color portfolios to register groups of colors at a reduced cost with the CRRC. ( Hunter L a b / Default SRV )
• AITL: Accredited Independent Test Laboratory. Independent lab accredited by the CRRC to evaluate radiative properties of roofing materials
• AMTL: Accredited Manufacturing Test Laboratory. Lab affiliated with a Licensed Seller or OM accredited by the CRRC to evaluate radiative properties of roofing materials
