    Feníe Energía, the installation agent’s company, is the independent energy distributor that has demonstrated the highest level of growth in Spain. Its model makes it stand out from other companies as it benefits from a network of energy agents who assess and understand the needs of the customer and who furthermore, are shareholders. Our mission is for customers to make savings through the work and experience of the network of energy agents, which is Feníe Energía’s own commercial network. They are the ones that maintain a direct contact with customers, providing them with personal assessment, which implies a close relationship and proximity with the customer and what they call “management through trust”. As a distributor of 100% clean energy committed to the environment, in addition to electricity and gas, the company offers energy saving, self-consumption, mobility and energy management services.

    The buildings in which Europeans sleep, eat, shop, learn and work, house a great opportunity for energy saving and emissions reduction, particularly in the so-called technical systems: heating, DHW, cooling, ventilation and lighting. A recent study by energy consultancy Ecofys, sponsored by Danfoss, shows the energy saving that can be achieved by improving energy management in Europe’s buildings. This hitherto under-exploited potential is calculated to save €67bn on the annual energy bill of European citizens by 2030, while reducing CO2 emissions by 156 Mt. Documents have been published as part of the study that focus on different types of buildings. This article sets out the main conclusions of the study in the case of supermarkets, along with some of the more recent success stories from Danfoss in this sector on the Iberian Peninsula.

    Buildings allocated to supermarkets in Europe occupy an approximate surface area of 115 million square metres. Part of the study included an assessment of the energy saving potential of a sample supermarket with a surface area of 1,025 m2 and a total energy consumption of 181 kWh/m2a. This sample building is equipped with a gas condensing boiler for heating (with energy recovery for the refrigeration system); mechanical ventilation systems with no heat recovery; a refrigeration and air conditioning system by means of compression chillers; and a direct and indirect lighting system via fluorescent tubes.


    Improvements to the technical systems in this sample supermarket reveal the possibility of achieving a 45% saving in energy, which translates into just over 8,000 €/year, with an investment of some €36,000 that would be amortised in around 4.5 years. Read more…

    To date, building certification standards have not taken into account the energy saving potential of every aspect relating to the automation and control of buildings’ energy consumption. The eu.bac methodology, based on currently applicable standards (EN 15232, DIN V 18599) and scientifically validated by the Technical University of Dresden (Germany), aims to fill this void. This article describes the success story of the hotel Pago del Olivo, demonstrating the savings potential that can be achieved in a building designed for hotel use following the application of this methodology.

    Opened in January 2011, the hotel Pago del Olivo is a three-star establishment located in Simancas (Valladolid), offering 36 rooms, a 70 m2 lounge as well as indoor and outdoor car parking. Sedical undertook the certification, for which end an authorised inspector visited the establishment. Using a standard questionnaire, filled out by the owner, the person responsible for the building or the systems integrator, the authorised inspector checked to see if the stated functions were available and active.


    Following a study of the documentation and the site inspection to check on the existence and type of control equipment, as well as ensuring it was working properly, the audit produced a score of 22 points with an E rating under the eu.bac system. The calculation tool also indicated that the installation had a margin for improvement of 78 points. Read more…

    The buildings where you sleep, eat, shop, learn and work hold a huge opportunity: EUR 67 billion savings on energy bills for EU citizens annually in 2030, and a reduction in emissions of 156 Mt. CO2. These groundbreaking results are presented in a study, released by energy consultancy Ecofys, a Navigant Company. The report, initiated by Danfoss, provides proof of the huge energy savings potential that can be obtained from better management of energy flows inside European buildings. A potential that has been insufficiently exploited.

    We spend most of our time in buildings. It is, therefore, no surprise that buildings consume a large amount of energy. But 75% of our housing stock is energy-inefficient. Most of the vast amounts of energy is used to maintain the right temperature and air quality in heating, cooling and ventilation systems – collectively known as a technical building system.


    When these systems are not working optimally, energy goes to waste, they cost money and cause damage to the health and the environment. But we have the technologies to prevent this. Consistent improvements could help reduce energy waste, cut costs and make our buildings better places to be. The report assesses a scenario where buildings are renovated in the period until 2030. The energy consumption in these buildings could be reduced by around 30% through upgrades to heating, cooling, ventilation, lighting and hot water systems.

    We have all the technologies at hand to make our buildings smart. Taking the findings of the new Ecofys study into account, we see that optimizing the control of energy flows inside buildings and leveraging new technologies, like digitalization, could deliver around 15% of the EU 2030 energy efficiency target. Political support is needed to remove barriers and accelerate the speed and scale of the investments. This will send the right market signals for innovation, jobs and sustainable growth,” says Andre Borouchaki, Senior Vice President and CTO, Danfoss.

    According to calculations by Danfoss based on the World Resources Institute’s report, Accelerating Building Efficiency, from 2016, reaching 15% of the EU 2030 energy efficiency target will create 300,000 new jobs.

    The EUR 67 billion we can save annually on a full application of high performance technical building systems, mostly from not importing gas from third countries, could be invested in Europe instead, providing additional comfort and well-being for EU citizens.

    The only way to significantly improve building energy efficiency is to focus on existing buildings. Nine out of ten of existing buildings in the EU will be occupied by 2050. Renovation of our building stock is more affordable than many currently believe. The investment cost for basic improvements of controls of energy flows inside buildings is low, and the payback time is two years to get the basics right.

    The consistent optimization of the energy use of technical building systems in existing buildings across Europe should start now,” says Dr. Andreas Hermelink, Associate Director at Ecofys, a Navigant Company. “We are talking about no-regret measures that can quickly deliver very significant reductions of energy consumption, energy bills and CO2 emissions. The revision of the Energy Performance of Buildings Directive should give a strong and effective push for unleashing the full cost-effective savings potential of technical building systems.

    Air conditioning systems are one of the main consumers of energy in commercial buildings. New construction looks for equipment that provides the greatest energy savings and helps meet the requirements of LEED, the most important certification for sustainable construction. This is the case of Pátio Victor Malzoni, a building situated at Avenida Brigadeiro Faria Lima in São Paulo city. Certified with the LEED Core & Shell Silver label, energy efficiency is a feature of this commercial development, saving 10% on energy by using Danfoss Turbocor® compressors in its air conditioning system.

    This air conditioning system has four TurboTosi chillers that are equipped with Danfoss Turbocor® compressors, made by Tosi Industries. According to Raul José de Almeida, Technical Director of TEKNIKA and the designer of Pátio Victor Malzoni, high-energy efficiency and low maintenance were achieved thanks to oil-free compressor technology. These reasons were deciding factors in the choice of TurboTosi equipment.

    As the building façade has over 65% of glazed area, a chiller with superior energy efficiency was needed to achieve the LEED certification. Energy savings of around 10% are expected by using TurboTosi chillers equipped with Danfoss Turbocor® compressors, compared to high-efficiency centrifugal chillers. Read more…

    The Barcelona metro has yet again placed its trust in Ingeteam, and is set to install the regenerative braking system developed by the company in its lines 3 and 4. At the end of last year, Transportes Metropolitanos de Barcelona (TMB) already installed this system in suburban line 9, so that this new contract confirms the validity and effectiveness of Ingeteam’s solution.

    This technology makes it possible to recover up to 30% of the braking energy of the train, in order to reduce CO2 emissions, and to lower the operator’s energy bill (TMB). The Ingeteam contract covers the installation of two units; one for line 3, one of the oldest lines in Barcelona, comprising 26 stations over an 18.4 km route, and the other for line 4 comprising 22 stations over a 17.3 km route. TMB uses the energy recovered at its own facilities, for indoor station lighting, escalators, etc.


    After a four year development phase and a 3 million euro investment in R&D&I, Ingeteam’s Traction Division has developed this regenerative braking system that is ideally suited to LRVs, trains and tramways, due to their frequent stopping requirements, which is precisely when the system recovers energy.

    The 29th edition of the Gas Forum which took place in Madrid last 6 and 7 October at the CNMC’s premises as part of the presidency of the European Union, discussed the need to assess the future of natural gas in Europe (up until 2030 and as from that date). Specifically, participants highlighted the need to start strategic discussions in the gas sector that address aspects including the impact of decarbonisation policies, developments in the electricity sector, the benefits of energy saving and the use of new technologies. Below is a summary of the main conclusions of this edition as contained in a document available on the European Commission website.

    The Forum saw intensive debate on the issues regarding the foundations of natural gas supply and demand in the EU, both for the pre- and the post-2030 periods. Despite differences in modelling and assessments, the Forum agreed on the need to start strategic discussions on this matter. This discussion should be based on an in-depth assessment of the possible drivers and consequences of the respective scenarios on all levels of the EU gas sector value chain. These include the evolution of decarbonisation policies, developments in the electricity sector, improvements in energy efficiency, new technologies for example in the field of gas-to-power or green gas, and market developments.


    The Forum welcomed the overall improvements in the EU market operation – as reflected in the ACER Market Monitoring Report 2015 which includes a health check on the wholesale gas market – but noted that in certain markets, this remains unsatisfactory. The Forum also took note of initiatives, such as CESEC and the implementation of the general Network Code, to address these shortcomings. The Forum confirmed the potential of LNG and storage in the context of diversification and the security of the supply, urging further scrutiny on a case-by-case basis to ensure the most efficient use of such an infrastructure.

    The lighting solutions from Schréder Socelec have achieved a high level of quality in the lighting renovation of the premises of Cañamás Hnos., a company specialising in the cultivation and processing of citrus fruits, by providing a high performance LED alternative at minimal cost to the owners. Thanks to the solution adopted, a saving of around 75% has been achieved compared to the total consumption of the previous lighting system that comprised old floodlights/bell lamps. In addition to saving energy, both security and comfort have been enhanced at premises that have a considerable movement of workers and vehicles.

    Cañamás Hnos., in collaboration with Schréder Socelec, has renovated the lighting at its fruit and vegetable plants located in Oliva and in L’Alcudia (Valencia) where the citrus fruit grown on its land is handled and processed.

    Schréder Socelec undertook a detailed study of the different industrial areas in which the employees work with different types of machines that create potentially dangerous situations. These areas require lighting levels that are adapted to that specific environment to guarantee the safety of the workers. Moreover, the luminaires have had to adapt to special conditions (flameproof, extreme temperature-proof, explosionproof, etc.).Read more…

    As governments focus on implementing their commitments to save energy and reduce carbon emissions under the recently ratified Paris agreement, a new report from the International Energy Agency (IEA) highlights the progress made by energy efficiency policies around the world over the past year, particularly in China and other emerging economies.

    The role of energy efficiency in the global energy transition is examined in the IEA’s Energy Efficiency Market Report 2016, which finds that its importance cannot be overstated. Simply put, there are no realistic or affordable energy and climate change policy without a sizeable and vigorous energy efficiency component.


    Energy intensity — the amount of energy used per unit of GDP — improved by 1.8% percent last year, meaning the global economy needed less energy to grow. The improvement exceeded the 1.5% gain of 2014, and was triple the average rate seen over the past decade. What’s more, last year’s gains were achieved in spite of lower energy prices, which generally dampen the enthusiasm for energy savings.

    However, the report also shows that while much has been accomplished, global progress is still too slow. Global energy intensity improvements need to reach at least 2.6% per year to put the world on a sustained pathway for a decarbonised energy system.

    Energy efficiency policies aim to deliver the maximum amount of social and economic benefit from the energy we use. For that reason, they are essential tools for government action that have a real impact on global energy demand. For instance, car fuel economy standards around the world saved 2.3 million barrels a day of oil last year, or 2.5% of the global oil supply.

    Efficiency standards now cover 30% of energy use globally, up from 11% in 2000. IEA countries saved USD 540 billion in energy expenditure in 2015 as a result of energy efficiency improvements since 2000.

    One country in particular showed significant progress, China, where energy intensity improved by 5.6%. That was up from an annual rate of 3.1% over the previous decade, according to the report. Primary energy demand in China grew by just 0.9% in 2015, its lowest rate since 1997, while the economy grew by 6.9%. Without this contribution, the global energy intensity improvements would have been just 1.4% in 2015.

    The IEA has identified energy efficiency as a critical “fuel” in the transition to a low-carbon economy. Its analysis has shown that over a third of all emissions reductions needed to reach climate goals by 2040 must come from energy efficiency policies. Efficiency gains in the IEA’s member countries were large enough to power Japan in 2015 making efficiency a critical component of a secure, sustainable energy system.

    The report demonstrates the central role of government policy in driving energy efficiency. It shows that policies must be strengthened and expanded to boost the potential gains from energy efficiency.

    Since 2013, the Hospital de Manises, together with its associated healthcare centres and special units, have managed to bring down their energy consumption by 16% as well as achieving a 50% reduction in CO2 emissions. These figures go beyond the initial objectives forecast for 2015, given that the target was to reduce the 2015 carbon footprint by 20% by means of measures including: saving energy on the consumption of gas and electricity, the green purchase of renewable energy sources of 100% of the electricity consumed in the area, a reduction in the number of business trips and the acquisition of hybrid vehicles for home care.

    The centre has obtained this good result thanks to the launch of an ambitious sustainable management programme that has been implemented alongside other actions including replacing the lighting system in the hospital and primary care centres with LED technology that consume less than conventional systems.

    A high level of performance has also been achieved from the centre’s solar thermal plant to reduce the consumption of natural gas in domestic hot water generation. The optimisation of the solar PV panels has been another savings factor as they are able to supply the consumption equivalent to all the lighting for the hospital’s main foyer over the course of 14 hours a day.
