Green buildings
In the specific case of building construction, the effective integration of certain quality and environmental aspects is accredited through the classifications obtained in sustainable certification seals. Among the project certifications that have been implemented by Sando or are currently underway are: LEED from the U.S. Green Building Council in the ‘Gold’ category; GBCe from the Green Building Council Spain in the ‘5-leaf’ and ‘3-leaf’ categories; and BREEAM from the Building Research Establishment in the ‘Excellent’ category.
These certifications are required by public and private clients in the execution of different buildings, and establish a series of requirements to be implemented in each project. Among the aspects included in these requirements are: responsible management of the project, of construction practices and of the impacts of construction sites and natural risks; the implementation of systems and processes that favour efficiency in energy and water management; the responsible sourcing of materials; and ensuring the biodiversity of the area.
Sustainable urban conservation and the creation of smart cities
Sustainable construction involves a number of key aspects in the implementation of public road maintenance projects, ranging from the installation of renewable energy sources or the use of recycled materials, to the construction of green areas for the regeneration of cities.
Through the company’s urban conservation and smart cities line, key projects for the development of sustainable infrastructures are carried out. From the field of urban mobility, through works such as paving using recycled materials or work on pavements with innovative materials to reduce noise pollution generated by vehicles.
También se integra la sostenibilidad en las actuaciones sobre el acerado o el espacio público para mejorar la accesibilidad peatonal; o en el acondicionamiento de distintas zonas urbanas y paseos marítimos para la regeneración paisajística, la protección ambiental y la creación de nuevos espacios para la sociedad.
Smart infrastructures for water management
In the face of water stress, it is vital to have infrastructures that ensure the efficiency of integrated water management at each stage: catchment, treatment, distribution, sanitation and purification, decarbonisation and waste management and recovery. In this last phase, energy efficiency and alternative energy generation projects are implemented, which are key to the decarbonisation of the economy.
Through the business line specialising in the integral water cycle, Sando Agua provides services in each of the phases, integrating the highest environmental and quality criteria. Within the field of construction, key hydraulic infrastructures are executed, including drinking water treatment, distribution networks, sewerage networks, wastewater pumping stations and wastewater treatment plants (WWTP).
In line with ensuring the efficiency of these infrastructures, the company integrates the Smartwater Cycle into their management, applying advanced information and communication technologies (ICT) to collect data in real time. The integration of this technology makes it possible to detect anomalies in quality or flow, allowing mechanisms to be activated to minimise loss in distribution, ensuring the healthiness of the water or preventing possible contamination by spillages.
Efficient materials that ensure the circular economy
Sando has a business line specialising in the exploitation, treatment, supply and transport of construction materials. To this end, it has several quarries distributed throughout Spain, which ensure that raw materials are obtained under the highest standards of quality and sustainability.
The quarries have specialised machinery depending on each material, allowing: the obtaining of natural aggregates as a result of the treatment of rocks or river gravel, or the manufacture of both cold and hot asphalt agglomerate. Así como son capaces de reconvertir los residuos de construcción de las obras en áridos reciclados para su reutilización, materializando la economía circular en los proyectos de construcción.
Sando is committed to the ongoing modernisation of these facilities to meet new environmental and efficiency requirements. For this purpose, it launched the MAPAS project: Modernisation and Adaptation of a Sustainable Agglomerates Plant at the La Cabaña production centre in Seville. A project developed with a European subsidy aimed at improving the sustainability of the pavements produced, reducing atmospheric emissions and energy consumption through lower manufacturing temperatures as part of the Recovery, Transformation and Resilience Plan within the State’s Sustainable and Digital Transport Support Programme.
