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

Cool Cities, Cool Planet - with Art Rosenfeld
Oct. 11, 2010 Science at the Theater: Berkeley Lab scientists discuss
how 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 worth
the time. Does are great job explaining heat and the world we live in.

4. 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.
5. WHY COOL ROOFS
THE 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
6. 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
8. COOL ROOF REBATES
• The Icing on the “Cake”
• Payback by “Utility Companies”
• Tax deductions
• Incentives are the Carrot
• Mandates are the Stick
9. RETURN ON INVESTMENT
• Project size, “81,770 sq. ft.
