The project seeks to minimize the urban heat effect by using new pavements with less solar storage than conventional ones, which also promotes energy savings of 7% for cooling devices and 5% for public lighting.
The Board of Governors has approved the participation of the City Council in this European program on which is based the use of this new material, designed in Murcia, which will be exported to other European cities if the results obtained are as expected.
Murcia will serve as a European laboratory to study quantitatively and qualitatively the effectiveness of cold asphalt in the fight against climate change in cities.
This is to verify the percentage of reduction that is obtained in the radiation with respect to the conventional pavement.
The initiative is part of the Life Heatland project, which 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 streets in the city - yet to be determined - 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.
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.
The 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.
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 €.
The installation of the new pavement could be carried out in 2018.
The Governing Board today approved the proposal of the Department of Employment, Tourism and Culture to participate in this project, whose estimated duration is 3 years.
