The Department of Development launches the "Life Heatland" project, a pioneering initiative that seeks to reduce urban heat through the use of new pavements, as well as energy consumption and greenhouse gas emissions associated with the urban environment

Murcia is one of the cities where the effectiveness of cold asphalt in the fight against climate change in urban areas is being experienced.

This is the "Life Heatland" project, an initiative that seeks to minimize the effect of urban heat by using new pavements with less solar storage than conventional ones.

This initiative, which addresses urban adaptation to the consequences of climate change, aims to verify the percentage reduction achieved in radiation compared to traditional pavement.

In particular, it seeks to reduce the effect of urban heat by using new pavements with less solar storage than usual, which will contribute to a better quality of life in cities.

Tests performed and future work

In the case of Murcia, the new white reflective chipboard has already begun to be installed, as a test, in various streets of the capital, to check if the behavior of the new material, which replaces traditional bitumen with synthetic binders, is similar to the traditional bituminous mixtures, and can be exported first to high-capacity roads in our city, and then to other urban centers.

The execution period for this project is two months and the execution budget amounts to 665,926 euros.

It is planned to act, once the test results are satisfactory, on a total area of ​​24,000 m2.

Energy saving and greater night visibility

The purpose of this initiative is to achieve a decrease in air temperature of 1.5ºC and surface pavement of 10ºC, in addition to an energy saving of 7% for cooling devices and 5% for public lighting.

In this regard, the Councilor for Development, Mario Gómez, explained that, "on the one hand, the performance coefficient of air conditioning and refrigeration devices will be improved, reducing their energy consumption; and on the other hand, the new material will have greater reflectance compared to conventional pavement, producing an improvement in night visibility and a reduction in the consumption of street lighting.
