Dallas Urban Heat Island Effect Part 1

Dallas roofing companies like DFW Best Roofing fare worried about the urban heat effect. Many people of a person experience that the cities are often warmer then the rural areas; research shows as much as 8 to 12 degrees Fahrenheit As cities develop, trees are cut down, buildings and concrete are put in its place; and these structures absorb more heat. This leads to the urban heat effect. Urban heat island effects were discovered in the 19th century by climatologists who measured differences in city temperatures and the rural side. Most often urban development practices often start with removal of trees and other vegetation. This reduces the cooling effects provided by vegetation and moist soils. This also adds buildings, rooftops, and pavement that absorb, store, and then radiate heat. In areas with tall buildings and narrow streets, heat can be trapped and airflow reduced. In addition, waste heat from air conditioning, vehicles, and industrial processes adds further to the city’s heat load. Since roof tops are dark as are the streets they absorb heat, thus heat island effect.

Dallas citizens had concerns about heat island effect and had plans and discussions, and there are several references in the 2006 Dallas Comprehensive Plan, forwardDallas! The plan’s mentions the heat island effect as a part of policies. Heat island policies are also found in other sections of the plan. The Dallas Urban Heat Island Study sees into how and where heat island effects occur in Dallas and some of the basic tools for reducing impacts, such as expanded tree planting and conservation, use of cool roofing, and application of cool and porous paving. The study describes costs and benefits associated with these ideas.
