Heat Islands & Cooling Strategies
/What are Heat Islands?
Heat islands are urban areas where buildings and roads absorb and re-emit more heat than natural landscapes, causing higher temperatures.
Causes of Heat Islands
Reduced Natural Landscapes: Less vegetation means less shading and cooling.
Material Properties: Asphalt and concrete retain more heat.
Urban Geometry: Dense buildings restrict airflow and heat dissipation.
Human Activities: Vehicles and air conditioning add extra heat.
Weather and Geography: Clear, calm weather intensifies heat islands; wind and clouds lessen them.
Cooling Strategies for Heat Islands
Increasing Vegetation: Adds shading and cooling.
Green Roofs: Reduces roof temperatures and improves stormwater management.
Cool Roofs: Reflective materials lower roof temperatures.
Cool Pavements: Heat-absorbent materials on sidewalks and streets.
Smart Growth: Development that enhances environmental quality and livability.
Monitoring of Heat Islands
Sensors like DL-BLG, DL-SHT35, DL-ATM22 and DL-ATM41 enable precise and continuous environmental data collection, helping to understand and address heat islands more effectively.
Accurate Data: Offer precise temperature and environmental measurements.
Real-Time Monitoring: Detect temperature changes quickly.
Long-Term Analysis: Reveal trends for assessing cooling strategies.
Spatial Variations: Identify specific hotspots for targeted actions.
Effective Strategy Development: Inform effective cooling measures.
Enhance Planning: Help cities develop sustainable solutions.
