Paving colour - to reduce localised heating

Paving should be light in colour to reduce solar absorption and mitigate the addition to the urban heat island effect. The alternative, dark pavers, would absorb more heat and potentially provides a hotter localised micro-climate on hot days.

The Green Star manual credit 25 requires paving to have a an initial Solar Reflective Index (SRI) of 39 or greater of 3 year SRI of 34 or greater. 

Also from this manual the typical SRI values of common surfaces:

  • Grey concrete 35

  • White concrete 86

  • Standard white paint 100

  • Standard black paint 5

  • New Asphalt 0

Pavers incorporating recycled glass

Island Block & Paving‘s produce a third party Greentag certified Pavers/Bricks/Blocks for the Future produict. This product is manufactured with 36.5% recycled glass aggregate, which is a by-product derived from recycled glass container bottles. The use of recycled glass in products results in reduction of cement and mined sand usage, and further reduces CO2 emissions. It also provides a cost-effective reduction in the total amount of mixed glass waste being sent to landfill. Pavers for the Future are available in different colours and surface finishes.
