  2. Discussion topics • Solar reflective roofing terminology • Key industry rating guidelines • The advantages of Landmark Solaris • Features and Specifications • Features & benefits of cool roofing products • Consumer considerations for purchasing SR roofing

  3. What is Solar Reflectance? • Solar reflectance (SR) or albedo is the ability of a surface material to reflect incident solar (short wave) radiation • Expressed on a scale of 0 to 1 • Total solar absorption (SR = 0.0) • Total solar reflectance (SR = 1.0) • In general, light-colored surfaces have higher solar reflectance than dark

  4. What is Thermal Emissivity? • Thermal emissivity (TE) is the amount of thermal radiation (infrared or long wave radiation) that radiates thermal energy (heat) away from its surface • Expressed on a scale of 0 to 1 • Total thermal absorption (TE = 0.0) • Total thermal emissivity (TE = 1.0) • Most roofing materials, except metals, have thermal emissivity values above 0.85

  5. Radiation Physical PropertiesAbsorptivity (α) – Reflectivity (ρ) – Emissivity (τ) α + ρ + τ = 1 τ = 0 for opaque materials Therefore, α + ρ = 1 or, α= 1 - ρ

  6. Key recognized industry ratings guidelines • CRRC - California Cool Roof Rating Council • Driving code adaption with Title 24 guidelines • Residential tier one utility rebates - .20 SR value • Residential tier two utility rebates - .40 SR value • Energy Star • The national standard • .25 SR value to qualify for asphalt & metal roofing • LEED H (LEED Residential standards) • An SRI value of 29 is required to qualify for a LEED point

  7. Landmark Solaris Specs & Features • Superior appearance & aesthetic quality • 300 lbs per square for superior durability • Limited lifetime warranty • Many competing products have 40-year warranties • No special installation requirements • Install is exactly the same as “normal” laminate shingle • 130 MPH wind warranty applicable when installed with SwiftStart and CertainTeed Hip & Ridge Acc. • Solaris Hip & Ridge accessory available

  8. Available in four colors shades* Dusky Clay Sunset Shake Aged Cedar Crystal Gray * Digital colors are approximate and color selections are best made from physical samples

  10. Energy Star® Rated Roof Product Features • Reflect more of the sun’s energy back into the atmosphere using high solar reflectance coatings or pigments • Release more absorbed heat back into the atmosphere using high thermal emissive coatings or pigments • Keep building’s cooler by reducing roof surface temperature • Reduce the amount of energy needed to cool buildings in warmer months • Help to reduce the production of air pollutants from electricity generation

  11. Benefits of Cool Roofs (Source EPA) • Potential for lower utility bills due to energy savings • Downsized A/C equipment • A reflective roof can reduced peak cooling demand by 10% to 15% which, may lead to the purchase of smaller, less expensive cooling systems • Extended roof life through surface thermal shock reduction • Reducing the expansion and contraction that occurs due to heating and cooling of the roof surface during the day • Potential for improved urban air quality • Decreased levels of pollution though reduced air temperature and cooling demand

  12. Reduce Urban Heat Island Impact • Heat released at night causing air temperatures to remain high • Urban and suburban areas are typically 2 to 10 ˚F hotter than surrounding rural areas Source: US EPA

  13. Impact of Elevated Temperatures • Increased demand for air conditioning • Particularly during peak demand times • Increased fuel use for vehicle air conditioning • Increased smog levels • Ozone, smog and acid rain which contribute to global climate change • Increased health problems related to heat and poor air quality

  14. Impact of the American Recovery and Reinvestment Act of 2009 • Federal Tax Credits for Energy Efficiency Home Improvements • All Energy Star labeled asphalt roofs qualify • Roofing products must be expected to last 5 years or have a 2 year warranty • Effective for 2009 and 2010 • Tax credit is 30% of cost • Maximum tax credit per homeowner for all home improvements is $1500 for 2009 and 2010 • Homeowner must save receipts and submit a Manufacturer Certification Statement • IRS Tax Form 5695 (2009 version)

  15. Quick Energy Savings EstimatesBased on Seasonal Electric Bills • 15 to 25 percent of the total cooling load cost for a house is due to the ceiling heat gain through the roof • Landmark Solaris Shingles can reduce the cooling load between 10 and 15 percent • Seasonal cooling cost ($) multiplied by the cooling load reduction (%), multiplied by the ceiling heat gain range (15% - 25%)

  20. Honolulu 2007 - Conservative energy savings estimate from Energy Star rated roof • Note the one year rise in energy costs • Energy costs will continue to rise over time 2008 costs 2007 costs

  21. Landmark (30) $80.00 30 Squares $2,400 shingles Landmark Premium $120.00 30 Squares $3,600 shingles Landmark Solaris $170.00 30 squares $5,100 shingles - $1,500 federal tax credit $3,600 shingles Lifetime warranted roof with improved “curb appeal” Improved home resale value Potentially lower utility bills Environmental improvement Federal Tax incentives* and the selling proposition for solar reflective roofing * Many state and regional municipalities and utility companies have additional rebate incentives and loan programs available for Energy Star rated roofing

  22. California Cool Roof Rebate Program Residential & Commercial examples from Calif. • Pacific Gas & Electric • Steep slope (Tier 1) - $0.10 per sq. ft • Steep slope (Tier 2) - $0.20 per sq. ft • Southern California Edison • Steep slope (Tier 1) - $0.10 per sq. ft • Steep slope (Tier 2) - $0.20 per sq. ft • Sacramento Municipal Utility District (SMUD) • Steep slope - $0.10 per sq. ft • Low slope - $0.20 per sq. ft
