Pinnacle roof meet energy star requirements.
For energy star compliance the roof coverings must be naturally aged for three years then the reflectivity and emissivity are measured.
The criteria for an energy star labeled roof are.
Energy star certified roof products can help reduce the amount of air conditioning needed in buildings and can reduce peak cooling demand by 10 15 percent.
Energy star program requirements for roof products eligibility criteria 7.
The energy star energy efficiency criteria do not include a specification for roof insulation.
For steep slope applications greater than 2 12 pitch.
Environmental protection agency s energy star program began rating roofing materials for energy.
Energy star initial requirements.
The provisions of title 24 allow for simulated aging called rapid ratings.
Meet 2008 california title 24 part 6 requirements which call for a cool roof or.
Initial minimum solar reflectance of 0 25 and 3 year aged minimum solar reflectance of 0 15.
So in 1999 the u s.
Reflectivity requirements differ for low slope and steep slope roofs.
The hotter the roof the more energy it takes to cool the building beneath it.
Estimated roof surface temperature reduction based on 1998 nist study.
