Thanks to a cloud-based efficient energy management platform that uses big data to optimise consumption, Siemens has enabled Gestamp, a multinational company in metal autoparts manufacturing, to reduce energy consumption by up to 15 percent at 14 of its plants. The Spanish company specialises in designing, developing and manufacturing metal autoparts to make lighter and safer cars, and has chosen Siemens as global supplier to implement this system and thus manage to optimise its energy needs in an industry that is increasing its energy consumption. The initial phase was the implementation of Siemens’ efficient energy management platform at Gestamp’s production plants in Spain, Germany, the UK, France and Poland. There are plans to extend the project to 30 plants, including China and USA, before the end of 2017.

Siemens’ platform makes it possible to monitor real-time energy consumption needs at various factories and to connect their infrastructure to a cloud solution that can instantaneously assess electricity and gas consumption.  This tool allows to define algorithms based on the consumption patterns to identify and warn about the energy malfunctions of the equipment. The energy consumption data can be processed through data analytic techniques to define predictive maintenance, to manage production processes or to forecast energy consumption based on future production requirements.


The final aim is to model the behaviour of the equipment so that it works as efficiently as possible and in a coordinated way, while also facilitating the reduction of CO2 emissions by 15% given the decreased energy consumption.

Siemens’ energy efficiency platform, managed from the company’s Smart Grids Control Centre in the Spanish city of Seville, has already been implemented in the Gestamp plants that consume the most energy. The aim is to extend use of the platform to other parts of the world where this automotive manufacturer has a significant presence, where results similar to those achieved in Europe are anticipated.

Accelerated amortisation

The plant consumption rationalization resulting from the data analysis and the solutions offered by this platform has enabled Gestamp to save almost 45 Gwh within the past 12 months. This sizeable figure results in a payback period for the investments less than three years.. It is a differential system due to its high resolution in collecting and processing information, in addition to its ability to cross energy consumption data with other variables, such as production. The aim is to extrapolate this information to understand the operation of the equipment, something that is helpful in decision-making. Alongside data collection and processing, the system makes it possible to define behaviour patterns using algorithms, in order to detect energy inefficiencies, to automate them and correct them.

Siemens and Gestamp are moving forward together to Smart Facilities and they are making real Industry 4.0 in the plants. Energy Efficiency project is one of the pillars of the partnership between Siemens and Gestamp within the framework of this initiative.

Electric introduced Continuous Efficiency, a suite of managed services and software that combines the knowledge of Schneider Electric experts across the globe with sophisticated tools and technology. The mix of onsite and remote support, as well as software, allows companies to uncover savings opportunities, implement changes at both the site and enterprise level, and constantly refine performance.

Continuous Efficiency blends utility, facility and operations management to reduce energy use and spend — 15 to 30 percent on average. It also goes beyond basic energy efficiency to help commercial and industrial firms develop proactive management and maintenance programs to help extend equipment life, reduce downtime and fine-tune systems for ongoing performance.


Key components of Continuous Efficiency include:

  • Data Acquisition & Quality – Best-in-class integration services collect and organize facility, energy and interval data along with utility invoices to provide a single, structured view of the most critical information to enable effective decision making.
  • Remote Analytics & Optimization – Energy specialists paired with advanced technology monitor facilities, identify energy conservation opportunities and the root cause of comfort and maintenance concerns, as well as ensure continual performance and verified savings.
  • Software Visualization – A single, cloud-based view of energy procurement, consumption and sustainability data allows energy managers to identify non-optimized facilities, equipment and behaviors, and prioritize energy efficiency projects based on the anticipated return on investment.
  • Onsite Consulting – A variety of collaborative, onsite engagements with Schneider Electric experts help identify energy improvement opportunities, train operations and facility managers, build internal support with executives, and design best practices to support certifications such as ISO 50001.

Continuous Efficiency is scalable to meet the needs of organizations as their energy and sustainability strategies, and facilities footprint grow and evolve. Managers can choose the support and technology most relevant to their current business and easily pilot new programs.

SediREC from Sedical is designed for the energy and volumetric management of water in heated swimming pools providing very high levels of energy efficiency. This system, able to manage one or several pools in the same sports centre all day long, has already been installed in different facilities, achieving excellent results that are even better than the forecasts made prior to installation. One such facility is the Altzate municipal sports centre in Lezo (Gipuzkoa), where the SediREC system has been in operation for nearly two years, achieving monthly savings on the energy bill of more than €2,000/month.

Inaugurated in 2001, the Altzate sports complex houses two swimming pools: the main pool (large) and a small pool which is used for aqua-gym, hydrotherapy and children’s swimming lessons. The total volume of both pools is 571 m3. Prior to the installation of the SediREC system in May 2013, management of the pools’ renovation water, essential to guarantee the required water quality, represented a cost of €3.76/m3, generating a monthly expenditure of €2,512. Table 1 provides an analysis of the operating situation of these swimming pools before installation of the SediREC system.

The custom of cleaning the filters for 5 minutes every 3 days for the large pool and 5 minutes every 2 days for the small pool, involved extracting a considerable volume of water from the filter with the associated energy loss being compensated for by means of boilers. Read more…

The rising cost of electricity and the drop in prices of PV systems experienced in recent years show that today the costs of PV generation are considerably lower than the purchase price of electricity. Moreover, the constant fall of feed-in tariffs has resulted in an increasing number of installation owners using the energy they produce before injecting it into the grid. To maximise self-consumption, storage systems are often used alongside energy management systems.

PV storage systems require inverters with more complex control systems and energy flows than those that have been available to date, given that they offer additional functions:

• Optimised inverter programming to make the most of valley tariffs.
• Improved grid quality.
• Emergency function in the event of a power outage.

The Fronius Energy Package and Multi Flow technology meet the strict requirements of a control system for a modern storage system. Read more…

Following the sharp increases in the price of energy over the last six years and the increasingly widespread incorporation of installations that offer added value to the establishment but which increase its energy expenditure (spas, swimming pools, gymnasiums, etc.), the hotel sector today is aware of the significance of energy as part of its operating costs. Proof of this is that fact that a large proportion of hotels have undertaken, or are considering carrying out, some form of measure to improve energy efficiency.

However a very large number of establishments lack knowledge and information regarding the energy consumption generated, which prevents the development of energy efficiency improvement measures and reductions in consumption with the sufficient technical solvency and the possibility of measuring and verifying the sought-after savings.

It is very important that the hotel owner improves their knowledge in terms of when, how, where and how much energy is consumed by the facilities of each hotel, as in this way they will have access to very valuable information to aid the decisionmaking process on the improvement measures to be carried out, offering a real tool to subsequently verify their effectiveness.

Energy management is an organised energy consumption forecast and control procedure that aims to achieve maximum possible energy output without diminishing performance level (comfort, light level, etc.). Energy is power in time and in this second factor, usage management is where energy savings can be achieved in addition to reducing the environmental impact of municipal installations.

A thorough understanding of the energy-consuming installations of a municipality requires the input of an expert technical team to assess the current situation and evaluate proposals that have acceptable investment recovery periods, give the necessary guarantees and offer the best technology in each case.

A3e, the association of energy efficiency companies, of which Letter Ingenieros is a member, proposes three types of audit depending on the level of detail required: diagnostic, audit and ESCO audit. For a municipality that would like to enter into an Energy Services (ESCO) contract the latter is fundamental as this will contribute information to the specifications that is non-binding in the event of inventory errors or subsequent investments that might be omitted from the tender. This latter audit should include a standardised study of the installations in order to establish the non-savings services to be included in the contract, as well as the business plan, so that the ESCOs can assess the profitability of the project with all the information on the table.

The Siemens Building Technologies Division has won the 2015 European Energy Service Award (EESA) in the Projects category for its implementation of an Energy Performance Contracting (EPC) project in the Polish city of Sosnowiec. This project focused on the heating systems and energy management in 87 public schools and preschools in this industrial city in the Silesia region. All heating and lighting systems in the buildings were modernized from the ground up in a period of just ten months. In addition, the Advantage Navigator energy monitoring system was installed to remotely monitor overall energy consumption.

The system allows personnel to remotely control the room temperature in every classroom and set it to the desired target value. “In the past, classrooms were typically kept too hot, which made it difficult for students to concentrate. Thanks to the state-of-the-art heating system and continuous energy monitoring we are now able to provide a comfortable learning environment for students,” says Marek Tobiacelli of Siemens Poland.

At the same time, Siemens has guaranteed heating cost savings of approximately 31 percent, electricity savings for lighting of 21 percent and a reduction of CO2 emissions by 5,220 t/year compared to the initial situation. The measures are financed through an Energy Performance Contract with Siemens. This means that the city of Sosnowiec’s initial investments of approximately 4 million euros will be paid back through the guaranteed savings realized over the ten-year contract period; interim financing is provided by Siemens.

The impressive energy and cost savings for the city as well the positive impact on the environment are a big win in and of themselves. However, the results achieved also benefit students and teachers who are now able to learn and work in classrooms offering a comfortable temperature – and hence a healthier environment.

The European Energy Service Award (EESA) is part of the European Energy Service Initiative toward the EU 2020 Energy Saving Targets (EESI 2020). This initiative aims at fostering the use of Energy Performance Contracting in Europe. The EESA honors outstanding efforts and achievements in the field of energy services in Europe. This year’s award ceremony will be held in Brussels.

Economic, social and cultural development has brought about a greater level of awareness of citizens as regards the demand for better quality services in every walk of life, and in particular, in the healthcare sector. Moreover, improvements in hygiene and health conditions, the rise in the standard of living, advances in biomedical research, better coordination and the development of primary care and specialist attention, have brought with them increased life expectancy and the consequent increase in the costs of healthcare that now accounts for over 8% of GDP, according to data from the European Observatory on Health Systems and Policies: Analysis of the Spanish Healthcare System 2010. Health Systems in Transition.

The Spanish hospital sector has over 800 hospitals with a very high energy demand. This is due to the fact that their installations require energy 365/24/7 for a large number and range of facilities and equipment. These include providing users and/or professionals with domestic hot water, temperature control (heating and cooling), maintaining air quality and its exchange, sterilisation processes, laundry, kitchens, lighting and the operation of hundreds of electromedical and industrial units.

The considerable weight of energy expenditure on hospital complexes necessitates the adoption of management measures designed to rationalise and save the primary energies required by their equipment and facilities. Read more…
