You won't be able to reverse your area's urban heat island
by yourself, but taking steps to mitigate its impact on your building (and your building's impact on maintaining the heat island) will deliver energy, air conditioning and financial savings to your building while you do your part to reduce the urban heat island
Thermal behavior of urban landscapes and the urban heat island
, Physical Geography 2(1): 19-23.
Where urbanization is high urban heat island
generate, in urban areas heat energy coming directly from sun trapped in the urban areas did not reflect back trapped in urban canyon at night this heat released by urban areas increased the atmospheric temperature of area (Oke et al., 1982; Quattrochi et al., 2000).
The urban heat island
intensity (UHII) is defined as the temperature difference between the urban and surrounding rural locations.
Following the definition of the urban heat island
intensity, as the temperature difference between the warmer area of the city and its suburb (Oke, 1973), in this research, as well as in the work of Cao et al., (2010), Chow, Pope, Martin, and Brazel (2011) and Ren et al., (2013), the intensity of PCI was defined as in the Equation 1.
Oke (1995) and Yow (2007) demonstrated that UHI could be divided into three types: Canopy Layer Heat Island (CLHI), Boundary Layer Heat Island (BLHI), and Surface Urban Heat Island
(SUHI) [12, 13] whereby the first two types refer to atmospheric urban heat island
The coatings industry has seen a similar need for helping to solve the urban heat island
effect and has worked to formulate coatings with the highest Solar Reflective (SR) values to develop a solution.
In 2015, Alliance Data--which believes better data drives better decisions --joined with American Forests to lay the groundwork for a landmark study about the urban heat island
effect and related air quality issues in Dallas, and the role of trees and greenspace to mitigate these climate issues.
Since climate change will bring a supplementary burden of heat exposure to cities everywhere, it is important to assess, as precisely as possible, which measures truly reduce urban heat island
effects, with minimal negative impact.
Not only are buildings packed so closely, there are few green spaces and most areas are covered with asphalt and concrete pavement and roads, thus contributing to what is known as the urban heat island
or UHI phenomenon.
That phenomenon, known as 'urban heat island
effect' can increase temperatures by as much as 20 degrees over what they would otherwise be.
TROMSO, NORWAY -- A novel form of the "urban heat island
" effect might be important in the far north, where warming is faster than in the rest of the globe, a study of five Arctic cities finds.
