What is energy efficiency?

Energy efficiency means obtaining goods and services with the least possible energy consumption while achieving the same or a better degree of comfort, polluting less, extending resources’ useful lives, and lowering operating costs. Based on that definition, energy efficiency initiatives seek to achieve the highest possible performance with the least consumption of energy.

Energy efficiency is a lever for the sustainable development of society, in both the environmental and economic dimensions, since efficient energy management greatly reduces the environmental impact of businesses, governments and citizens while contributing to the long-term economic viability of society as a whole.

How do we work in the area of energy efficiency?

To maximize our energy efficiency and that of the companies, governments and institutions that rely on Ferrovial Services, we develop projects using the following levers:

  • Innovation
  • Big Data
  • Reuse of resources and waste to produce energy
  • Renewable energy generation
  • Cost-cutting, sustainable finance and budgetary stability
  • Results-orientation and reduction of operating risk
  • Equipment maintenance
  • Collaboration with companies and institutions

What do we propose in energy efficiency?

Energy efficiency cuts across all business areas in Ferrovial Services. From streetlight contracts with local governments to energy management in hospitals, from tapping the energy in landfills to facility management, Ferrovial Services’ extensive experience as an energy service company (ESCO) gives it the capacity and expertise to design and implement highly complex energy efficiency projects.

Ferrovial Services specializes in energy management in the broadest sense, including developing technologies to enhance the efficiency and use of renewables, for both public and private sector clients, outdoor and indoor lighting, heat and hot water production, climate control, network optimization and telecontrol. Innovation is the core around which Ferrovial Services implements energy efficiency initiatives.

As an energy service company, Ferrovial Services works mainly in the following areas:

  • Public lighting
  • Municipal buildings and installations
  • District heating
  • Energy services in hospitals
  • Renewable energy production
  • Industrial installations

Energy efficiency projects

Energy Control Center


The Center is a collaborative workspace centralizing energy management and know-how in relation to energy efficiency services. The Center manages many types of contracts: from hospitals and elderly care homes, schools, sports centers, offices and processing plants, to district heating and power plants. This solution uses telemetry to manage more than 4,000 supply points and 2,500 devices in Spain, the United States and Portugal, analyzing 316 gigawatt-hours of energy consumption.


IoT (Internet of Things)

Ferrovial Services also has a platform — called XPERiot — for individual and aggregate remote management of each light in a street lighting system, for controlling operating schedules, regulating lighting levels and monitoring their operating parameters. This solution helps achieve further progress towards the intelligent use of data analysis and digitalization in order to enhance operating efficiency.

District Heating

The district heating project in San Sebastián (Spain) uses centralized heat production from biomass to meet the demand for heating and air conditioning of around 1,500 homes in the city’s Txomin Enea district. By using biomass, this project cuts CO2 emissions by a total of 1,800 tons per year. This initiative also saves costs for operator and end user alike.

Geotermabok: Geothermal energy from landfills

The GEOTERMABOK project is a proof-of-concept for the use of geothermal energy systems, normally applied to the ground, in order to extract the heat generated in a landfill. The project also analyses potential uses of the heat, such as powering processes in the landfill itself (e.g. leachate processing) and external applications.

Energy efficiency services for hospitals

Ferrovial Services delivers energy services at many hospitals throughout Spain. Particularly noteworthy is the Smart Hospital project at the Marqués de Valdecilla Hospital in Santander. The new in-patient building combines maximum efficiency in its installations with rationalized execution costs. Additionally, energy consumption at the existing facilities was cut by 12%. The experience accumulated by the Center of Excellence for Infrastructure made it possible to optimize the lighting upgrade and improve the facility’s costs by 10%, all while fulfilling the established plan. Among the hospitals in the Madrid region, Móstoles Hospital underwent sweeping upgrades to the principal energy-consuming equipment in the main building and in outlying clinics. The project also includes management of heating and air conditioning, cooling, climate control, lighting, facilities control and vertical transport equipment. These actions will together save more than 1.5 GWh in electricity and 0.3 GWh in thermal energy, reducing CO2 emissions by 600 tons per year.

Conected lighting

In Tomar (Portugal), we developed a project that included installing a new smart, connected street lighting system comprising 14,000 lights, and the implementation of four pilot projects: monitoring the use of fire hydrants, air and water quality monitoring, tracking flood levels in the Nabão river, and implementing artificial intelligence software to manage the entire system. This software will use a LoRaWAN communications network to manage all communications, based on the Internet of Things (IoT).

Who do we work with?

Ferrovial Services develops energy efficiency projects for public and private sector clients in the countries where it operates. We also work within the European Union’s regional development framework in projects funded by the ERDF. In the area of innovation, Ferrovial Services works with local, regional and national governments, with technology firms and in an open innovation system.

Managing more than one million points of light around the world (four times the number to be found in a city like New York), extensive experience as an energy service company and  the possibility of moving towards renewable energy generation are key factors that contribute to making Ferrovial Services a leader in energy efficiency.
