Consumer considerations for purchasing SR roofing

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 1Total solar absorption (SR = 0.0)Total solar reflectance (SR = 1.0)

In general, light-colored surfaces have higher solar reflectance than dark

What is Solar Reflectance?

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 1Total thermal absorption (TE = 0.0)

Total thermal emissivity (TE = 1.0)

Most roofing materials, except metals, have thermal emissivity values above 0.85

What is Thermal Emissivity?

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

Key recognized industry ratings guidelines

CRRC - California Cool Roof Rating CouncilDriving code adaption with Title 24 guidelines

Residential tier one utility rebates - .20 SR value

Residential tier two utility rebates - .40 SR value

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

Benefits of Cool Roofs (Source EPA)

Potential for lower utility bills due to energy savings

Downsized A/C equipmentA 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 reductionReducing the expansion and contraction that occurs due to heating and cooling of the roof surface during the day

Potential for improved urban air qualityDecreased levels of pollution though reduced air temperature and cooling demand

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

Impact of Elevated Temperatures

Increased demand for air conditioningParticularly during peak demand times

Increased fuel use for vehicle air conditioning

Increased smog levelsOzone, smog and acid rain which contribute to global climate change

Increased health problems related to heat and poor air quality

Impact of the American Recovery and Reinvestment Act of 2009

Federal Tax Credits for Energy Efficiency Home Improvements

All Energy Star labeled asphalt roofs qualifyRoofing products must be expected to last 5 years or have a 2 year warrantyEffective for 2009 and 2010Tax credit is 30% of costMaximum 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)

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%)
