InVEST Urban Cooling Model

The InVEST urban cooling model calculates an index of heat mitigation based on shade, evapotranspiration, and albedo, as well as distance from cooling islands (e.g. parks).

Urban heat mitigation is a priority for many cities that have undergone heat waves in recent years. Vegetation can help reduce the urban heat island by providing shade, modifying thermal properties of the urban fabric, and increasing cooling through evapotranspiration. This has consequences for health and wellbeing of citizens through reduced mortality and morbidity, increased comfort and productivity, and reduced need for air conditioning (A/C). The InVEST urban cooling model calculates an index of heat mitigation based on shade, evapotranspiration, and albedo, as well as distance from cooling islands (e.g. parks). The index is used to estimate a temperature reduction by vegetation. Finally, the model estimates the value of the heat mitigation service using two (optional) valuation methods: energy consumption and work productivity.

The urban heat island effect affects many cities around the world, with major consequences on human health and wellbeing: high mortality or morbidity during heat waves, high A/C consumption, and reduced comfort or work productivity. The urban heat island effect, i.e. the difference between rural and urban temperatures, is caused by a change in the energy balance in cities due to two main factors: the thermal properties of materials used in urban areas (e.g. concrete, asphalt), which store more heat, and the reduction of the cooling effect of vegetation (through shade and evapotranspiration). Natural infrastructure therefore plays a role in reducing the urban heat island in cities. Using the rapidly-growing literature on urban heat modeling (Deilami et al., 2018), the InVEST urban cooling model estimates the cooling effect of vegetation based on commonly available data on climate, land use/ land cover, and (optionally) A/C use.
