<br />4.3.7.12. Mitigation
<br />There are many ways to mitigate for extreme heat events. Mitigating from the health effects of extreme
<br />heat can be having air conditioning, cities opening cooling centers, or adjusting work ours for those
<br />individuals who work primarily outside. There are some energy efficiency measures in houses and small
<br />commercial buildings can help to keep the indoor environment within comfortable temperature
<br />conditions without use of air conditioning during extreme heat events such as: roof deck insulation, wall
<br />insulation, high performance windows, and building orientation.
<br />Mitigation strategies that require coordination and construction include shading of buildings, asphalt and
<br />other dark surfaces with trees can reduce the UHI effect. Solar panels placed on canopies over parking
<br />lots and other paved surfaces can also shade and reduce the UHI effect. Direct shading of buildings also
<br />reduces heat in buildings in the event of power outages in an extreme heat event. However, tree planting
<br />requires adequate space, water, and maintenance, and the correct selection of trees. Another mitigation
<br />strategy is the management and restoration of parks in urban areas increases vegetated areas, which can
<br />help reduce heat island effects. Increasing recreational and riparian spaces in urbanized areas has many
<br />additional benefits including health benefits from air and water quality improvements. Additionally, there
<br />are pavements that have technologies to reduce heat island effects. The pavements reflect more solar
<br />energy, enhance water evaporation, are more porous, or have been otherwise modified to remain cooler
<br />than conventional pavements.
