The project seeks to minimize the effect of urban heat through the use of new pavements with less solar storage than conventional ones, which also leads to energy savings of 7% for cooling devices and 5% for public lighting
The Councilor for Urbanism, Environment and Huerta, Antonio Navarro presented this morning the project 'Life Heatland' for which Murcia will serve as a European laboratory to study quantitatively and qualitatively the effectiveness of cold asphalt in combating climate change in the cities.
The initiative aims to check the percentage of reduction achieved in radiation compared to conventional pavement, a project that directly addresses urban adaptation to the consequences of climate change.
In particular, it seeks to minimize the effect of urban heat by using new pavements with less solar storage than conventional ones, which will contribute to a better quality of life and human well-being.
In the case of Murcia, the new pavement will be installed on 24,000 square meters of city streets to check if the result is reliable and can be exported to other European capitals.
Specifically, it is expected that the pavement albedo will be reduced from 0.05 for conventional asphalts to 0.46 for the new technology.
Four measuring towers will be installed throughout the test program, allowing 1.5 million data to be obtained, since they will record, every 30 minutes, 24 hours / day and for 2 years, the following parameters: surface temperature air temperature, humidity, wind speed, solar irradiation, ozone air, lighting level and noise.
A project whose estimated duration is 3 years.
Together with the City of Murcia, the Business Research Association of Murcia (CTCON) and the construction company CHM Obras e Infraestructuras, SA (both inventors of the new material) are part of the project, in addition to the Federation Regional Entrepreneurs of Construction of Murcia (FRECOM) and the cluster of the construction sector of Slovenia.
The program has an overall budget of 1.3 M €, of which the City Council will contribute € 146,000 and receive € 200,000 of European funds.
The installation of the new pavement could be carried out in 2018.
The aim is to achieve a reduction of the air temperature of 1.5 ° C and surface pavement of 10 ° C, as well as an energy saving of 7% for cooling devices and 5% for public lighting.
In addition, the project plans to develop a mathematical model to predict the effect of pavement implementation in other urban areas and a demonstration of the financial balance of the new technology.
It will be tested in at least 4 cities.
Navarro said: "This Life Hestland project will help mitigate climate change as the innovative solution reduces energy consumption and greenhouse gas emissions associated with typical technologies in the urban environment."
Thus, on the one hand, it will improve the coefficient of efficiency of air conditioning and refrigeration devices, reducing their energy consumption and, on the other hand, the new construction material used will have a higher reflectance compared to conventional pavements and also producing an improvement in night visibility, potentially reducing lighting requirements and thereby producing energy savings.
