Green and cool roofs to mitigate urban heat island effects

Dr Ashish Sharma of the University of Notre Dame (US) has completed a report on whether green roofs, which are covered with plants, and cool roofs, which are surfaced with reflective materials, could reduce Urban Heat Islands (UHI) effects in Chicago.

Dr. Ashish Sharma, doing post-doctural research in Environmental Change Initiative at University of Notre Dame whose research interests include Atmospheric Sciences and land-ocean atmosphere.  He achieved his PhD in Climate Science 2012.

Dr. Sharma spoke of “green” and “cool” roofs – the former having more benefits but of course needing water and a strong roof structure and useful in cities and populated areas probably producing vegetation. Could sustain urban bees and/or provide shade, and can have a pollutant-cleansing effect.

Whereas “cool” roof is basically a reflective roof, for example “Thermoshield” which can be painted on and has both reflective and insulating properties, and can reflect Infra Red.  Today’s podcast follows on from last week’s Beyond Zero Radio interview with Thermoshield, an Australian cool roof paint product which is headquartered in Dandenong, Victoria.
