What is an Urban Heat Island?
1. Define “Urban heat island”: Is an urban area that are warmer than usual from their rural surroundings, that makes an island of high temperature.
2. Sketch the temperature variations as shown on the website onto the profile below. Discuss which areas are cooler.Downtown has cooler temperature during the day. Most rural areas are cool at night.
3. How do heat islands form? Describe 2 methods that contribute to higher urban temperatures from heat islands. Heat islands are formed on the surface and in the atmosphere. The sun heat can dry, exposing urban surfaces like roofs and pavement. Two methods that contribute to higher urban temperature would be increasing levels of energy consumption and emissions of air pollution.
Why Do We Care About Heat Islands?
4. Discuss the environmental benefits/detriments of wintertime and summertime heat island areas. Detriments of wintertime and summertime are, the increase of peak electricity, high energy demand, high demand of water.
5. What are some of the things that can be done to reduce the urban heat island effect? Increase trees and vegetative cover, creating "green roofs".
6. What is the temperature variance in green roof vs. traditional roof? Green roof is cooler while traditional roof is at least up to 90 degrees.
7. Describe some benefits of green roofs:
-Provides insulation
-Creating a habitat for the wildlife
-Reduction of energy usage.
Heat Island Impact?
8. What are the 4 major impacts of urban heat islands?
1) Increase energy consumption
2) Elevate emissions of air pollutants
3) Compromise health and comfort
4) Impair water quality
9. Name 2 human health effects of heat islands
1) Heat cramps
2) Heat strokes
Urban Heat Island Mitigation
10. What is a cool pavement? Is paving material that can reflect solar energy, as well as enhance water evaporation. Is modified to be cooler than conventional pavement.
Where You Live?
List 2 things that are currently being done to help mitigate the effects of urban heat islands.
1) Develop and adapt an urban area island mitigation policy
2) Support the Community Forest Initiative.
