Highly confused by conflicting material regarding albedo.
Does anyone have any tricks to help remembering if high or low albedo is preferred?
what is the preferred albedo to reduce the heat island effect?
Ballast says we want a low albedo and high conductivity. Stating "examples of materials with low albedo are traditional concrete and dark colored gravel."
Other sources seem to say "Paving and roofing materials with, respectively, HIGH albedo and solar reflectance index values, help in mitigating heat island effect as they reject and reflect more energy. Green roofs, despite having have LOW albedo, can help to a great extent in reducing the heat island effect."
Any clarification or tips would be greatly appreciated!!!!
