WebDec 19, 2024 · The technical name for a roof that reflects heat is that it has a high albedo. High-albedo roofing has two scientifically proven benefits: it helps to mitigate the urban heat island effect and reduce cooling energy demand and costs. It can also increase thermal comfort in non-conditioned buildings. Benefits are both direct and indirect. WebApr 12, 2012 · An albedo increase of 0.1 in urban areas corresponds to increasing the albedo to roofs by an average of 0.25 and the albedo of pavements by 0.15. This would lead to a global temperature reduction equivalent to decreasing CO 2 emissions by (6.5–7.5 kg m −2 ) × (0.10/0.01) × (1.5 × 10 12 m 2 ) = 10 × 10 13 kg–11 × 10 13 kg, or 100 ...
