COOL ROOFS• A cool roof is one that reflects the sun’s heat and emits absorbed radiation back into the atmosphere.

COOL ROOFS LINKSCool Cities, Cool Planet - with Art RosenfeldOct. 11, 2010 Science at the Theater: Berkeley Lab scientists discusshow cool roofs can cool your building, your city ... and our planet.This is an one hour and forty five minutes long, but this it is well worththe time. Does are great job explaining heat and the world we live in.http://www.youtube.com/watch?v=Zp-B0v0bdxo
COOL ROOFS• The two basic characteristics that determine the ‘coolness’ of a roof are solar reflectance (SR) and thermal remittance (TE). Both properties are rated on a scale from 0 to 1, where 1 is the most reflective or emissive.
WHY COOL ROOFSTHE AMERICAN INSTITUTE OF ARCHITECTS• Lower roof top temperatures• Reduce cooling loads• Reduce use of air conditioning system• Longer service life of the roof• Reduce energy during peak electricity demand• 10-30 % of cooling energy need
WHY COOL ROOFS• Cool Roofing: Beyond Myths to Solutions• Do Cool Roofs Fit in Cool Climates• Finding Incentives for Cool Roofs• Guidelines for Selecting Cool Roofs• Reflective Roof Coatings Improve A/C Efficiency• Reflective Roof Coatings – Architects Consultants• Reroof or Restore• Energy Efficiency & Renewable Energy
