Temperature and UHI
Are you aware of the importance of Urban Heat Islands (UHI) analysis in urban planning, environmental and city management?
Urban heat islands are phenomena that occur when some urban areas reach higher temperatures than surrounding rural areas. . This event is the result of an excessive concentration of buildings, flooring and other constructions that tend to alter the heat balance of cities.
The relevance of UHI in terms of sustainability is quite understandable, as these can:
- cause local temperatures to rise, affecting air quality;
- alter the ecosystem;
- have negative effects on people’s health.
UHI analysis: the most important parameters to protect the environment
There are several parameters, extremely useful for a sustainable city management, that can be obtained from UHI analyses. Let’s check them together.
This is the parameter that refers to the surface temperature information of urban and rural areas. This data is used to quantify the temperature difference between diverse areas.
Earth surface temperature is the one you can feel by touching the ground. It has a particular importance as the heat rising from Earth can affect the climate and the environment.
This parameter refers to the average temperature difference between urban areas and surrounding rural areas.
This parameter refers to the total surface area covered by the temperature difference between urban and rural areas.
This parameter allows you to quickly find information about the type of land coverage, such as the number of buildings, the presence of floorings and other man-made activities . This way you can identify the areas most affected and most exposed to the effect of UHIs.
An extremely useful parameter to identify the areas that absorb and retain the most heat, affecting the formation of urban heat islands. When we talk about Albedo, in fact, we refer to the amount of solar radiation reflected from the Earth’s surface.
Global surface temperature has increased by about 1.2°C since the pre-industrial era
UHI and temperatures: an algorithm to support ESG decisions
UHI analysis is a key practice to make changes to cities from an urban, environmental and managerial perspectives. By integrating this algorithm into our platform, we want to support governments and decision makers by providing them with objective, scientific and statistical data about urban heat islands.
Specifically, the UHI and Temperature algorithm is used for:
- Urban development plans. By identifying the areas that most risk thermal overheating, you can make conscious and targeted decisions to plan urban development in a functional way, so as to reduce the effects generated by heat islands.
- Energy management at its best. Thanks to this algorithm you can more easily identify the areas that require the installation of air conditioning or cooling systems. This way you can optimize the use of energy, acting directly on the most suitable areas.
- Climate change mitigation. You can plan interventions that work to mitigate the negative effects of climate change. Thanks to UHI analysis, in fact, you can easily identify areas at high risk of thermal overheating, and take the most appropriate measures to fight it, such as: creating green zones or building low-energy buildings.
- Public Health, by planning pollution-limiting interventions to improve air quality after identifying areas with high risk of thermal insulation.
- Manage emergencies as best as possible and identify areas with a higher risk of thermal insulation, by taking specific safety measures such as creating evacuation zones or deciding for a better arrangement of cooling systems.
It’s easy to understand why UHI analysis is so important, as it can help make more informed, conscious and sustainable decisions by providing valuable insights for urban planning, city management and Public Health protection.
