1. It seems pretty common for the US cities shown on this site to have differences of up to 20˚F. This is a staggering number, and quite a bit larger than I would have predicted. 2. Toronto Canada, is in close proximity and size to Chicago, I can use the numbers for Chicago as a relative comparison. Chicago's UHI reaches temperatures up to 21˚F higher than rural areas, and causing high stress to the electrical grid and health risks for residents.. Toronto has the most high rise building of any city in North America, which is surprising but also drastically effects the UHI effect in the growing downtown core. 3. One of the first measures I would propose would be a widespread regulation on the colour or material covering the rooftops of high-rise buildings. The change of colour, or addition of green roofs to high-rises would drastically affect the retained heat in buildings and aid in the evapotranspiration. Also, painting the sides of buildings to be lighter and using polarized glass to reduce reflectivity. 4. Green roof incentive programs exist in Toronto that allow grants for green roofs. There have been no policies or regulations implemented that enforce their construciton.
