Portland State study shows ways to reduce extreme heat in city neighborhoods
  • Trees, reflective materials and green roofs could be a solution to urban heat islands, as shown in new study from Portland State University.
  • The biggest differences could come from reflective materials and planting trees; green roofs require more studies.
  • Researchers used computer modeling to study potential temperature differences that could be made with eco-friendly development in various property types.
  • They also found that the opposite - like paving over places with trees - can increase temperatures by 25°F on summer days.
  • Urban heat islands are associated with higher pollution and negative health outcomes.
