Architects from the Polytechnic University of Cartagena (UPCT), four young people of the 92 generation, specialized in green infrastructure, urban planning, building and landscaping, have created the business project Greening, green infrastructure design and focused on promoting the advantages of vegetable covers in public and private buildings.
"For a building, a green roof is like being sheltered by a tree," exemplifies one of these entrepreneurial architects, Alfonso Bernal.
"It generates shade, dissipating a good part of the solar radiation, and the temperature is significantly reduced," he adds.
In the model they created to show their project in the Engineering Campus, the differences in temperature compared to a traditional cover were almost 15 degrees.
"On the upper floors of the buildings could be achieved reductions of at least five degrees, with the consequent decrease in air conditioning needs", calculates the former alumnus of the UPCT Pedro Francisco Sánchez.
"It increases the thermal insulation because much of the heat is absorbed by the water and the substrate of the plant," he explains.
Urban benefit A widespread implementation of these solutions would also reduce the heat island effect suffered by cities due to the high temperatures concentrated in urban materials, but the advantages of plant covers go beyond the climatic, as the plants would also serve to " retain pollution and reduce greenhouse gases ", continues the architect and graphic designer María Degania Medina.
"It generates benefits both on an urban scale and on a building scale and technically it is not more complex than designing a traditional roof," comments his colleague Francisco José Galián.
"It is an investment that recovers by saving on air conditioning and that increases the aesthetic value of the building while generating an exclusive garden for the neighbors," he says.
"In addition, the solar panels work better on a vegetal cover that refrigerates them", it completes.
Plant covers can be intensive, with a depth of up to one meter to plant trees, but the UPCT alumni propose for the Region extensive systems of just 10 centimeters deep and Mediterranean plants efficient in water consumption, with little air development and without needing much substrate.
"Endemic or threatened species could be used to collaborate with conservation and awareness programs," says the female component of the team.
Greening is already offering advisory services to interested private companies and carrying out green infrastructure projects for the City of Murcia and the Autonomous Community.
Alumni emphasize that with green roofs you can apply for national and international sustainability certificates, such as the Breeam or the green certificate, by reducing the carbon footprint and increasing the efficiency of buildings.
Working for the Administration This business initiative that connects Architecture and Agronomic Engineering is the result of the experience of the four graduates in projects of the research group in Hortofrutícultura and the Urban Research Laboratory of environmental restoration in Murcia Río and urban analysis with the PGOU of several municipalities of the Region.
"Green infrastructures are going to be a turning point for municipal environmental policies," says UPCT researcher Jesús Ochoa, who trained the members of Reverdecer in the subject Territory, Landscaping and Gardening, which they put into practice with the design of a vertical garden and an informative parterre with native species in the Espacio Mediterráneo shopping center
