ALEM The Local Energy and Climate Change Agency of Murcia has participated in the Third Congress of Local Governments in Krakow held on 28 and 29 March 2017. The invitation to this congress has been forwarded by the Office of the Economic Forum of Poland To ALEM, which had already taken part in other editions in the European Energy Forum that also organizes this institution.3rd congress of Local-goverments--Murcia-Murcia has presented at this congress the latest actions carried out in the Municipality Murcia on mobility, sustainable development and energy planning offering the keys and main objectives of the Municipal policy in the field of e-mobility, renewable energy and energy planning. There are aspects that are being approached within the European Project “Roadmaps for energy” in which the City of Murcia participates through ALEM.

In relation to this project was explained that aims to create roadmaps that allow us to evolve from the point where our cities are to an ideal situation in the future, through specific initiatives and actions, where we will be able to offer the best public services to our citizens. The project focuses on areas that have a major impact from the energy point of view, such as buildings, mobility and urban spaces.28 wawel 12 30 (21)

Concerning the actions related to sustainable mobility, the importance given to the construction of new segregated cycle lanes was explained to connect the city longitudinally and transversally and some of the most important points were advanced in relation to the Local Strategy of the Electric Vehicle that will soon be officially presented.

Both during the session and in the subsequent debate, ALEM was able to offer more details about the aforementioned actions and in the end it was able to make known to other European cities and entities the work that the City of Murcia is being carried out in these axes and placing the City Strategy Murcia 2020 as a backbone of all the Municipal action.

CRESCO Award “Sustainable Cities” 2016- PALERMO

CRESCO Award “Sustainable Cities” 2016- PALERMO

The City of Palermo was awarded a special prize instituted by Enel for ”Sustainable energy services Innovation in urban areas” for the year 2016. About 340 municipalities, in which live more than 12 million people,  took part to the competition,  divided in  various categories.

The Enel prize, (Enel is a company that distributes electricity throughout the country), is dedicated to the innovation of sustainable energy services in urban areas. The goal is to award the City who has undertaken the most interesting program of initiatives to integrate the intelligent use of energy and the development of services to improve the quality of life in urban areas. The City of Palermo won the Enel award 2016 for a project aimed to improve the energy performance of the municipal housing stock, making more efficient and rational energy consumption in buildings, and creating a positive environmental impact in terms of CO2 reduction.

Following the award, Enel proposed to the Sicilian Municipality the signing of a Memorandum that allows local administration to transform innovative projects in services for the territory and citizens using the technologies and know-how made available by the electricity company. The initiative is part of the European campaign “Sustainable living in cities”, launched last April by CSR Europe – the network promoted by the European Commission to implement the EU Agenda on Sustainability – to define effective models of multi-stakeholder partnerships for sustainable development of urban territories.

The awarded project has the  title “ROADMAPS FOR ENERGY“, funded by the European Union within the framework of Horizon 2020. This program is aimed at identifying the programs and goals for sustainable development and the reduction of CO2 emissions within  2050 in some European cities. The project has a duration of three years and involves mainly the construction of a study activity  and a coordinated planning between European cities, to define a project “portfolio” with particular reference to energy efficiency in buildings and sustainable mobility.

Other European cities participating in the project are: Eindhoven, Murcia, Tallinn, Forli, Istanbul, Newcastle, Sant Cugat and Palermo.

For the City of Palermo the mail office are involved in tha activities are:  Environment Office, Technology Innovation Office, Extramunicipal Funds Office, School Buildings Office and the Department of Education.

In particular, ENEL has awarded the City of Palermo for the idea of ​​building a “Strategy for Energy Efficiency”, contained in the Sustainable Energy Action Plan (approved by the European Commission in 2015), which covers both the municipal organization, both the energy efficiency of municipal buildings, and public training and awareness on the issues mentioned above. This can be summarized in the following steps

  1. Establishment of an energy management system in compliance with UNI CEI EN ISO 50001, and the appointment of an Energy Manager;
  2. Energy Catasto realization of municipal buildings and an energy audit campaign, with particular reference to school buildings;
  3. Analysis of energy consumption of municipal housing and identification of energy and environmental performance indicators for the identification of energy efficiency priority
  4. Energy audit realization in public buildings with particular reference to school ones
  5. Realization of interventions of maintenance and of monitoring of energy consumption and of the energy produced by existing photovoltaic systems, aimed at maintaining the production of electrical energy from renewable sources
  6. Energy efficiency of municipal buildings
  7. Energy certification of municipal buildings and the realization of the first “plate energy”
  8. Dissemination of information on energy efficiency projects in school buildings, such as “pilot projects” reproducible in other buildings
  9. Realization of audiovisual and educational books produced for the implementation of training programs and promotion of renewable energies in the municipal schools
  10. Dissemination among citizens of the city of Palermo and other European cities of the SEAP actions and drafting of a project portfolio for Palermo in 2050.

Sustainable and smart mobility plans of Murcia

Sustainable and smart mobility plans of Murcia

The Official College of Industrial Engineers of Murcia, COITIRM, held on 6th April 2017 a seminar to discuss the Energy Plan of the Region of Murcia within the framework of the Forum of Innovation and Impulse to Renewable Energy in the Region of Murcia, INNPULSA 2017. For this occasion the College wanted to have the saying of the Murcia city council in order to know firsthand what will be the actions planned to promote sustainable and smart mobility in our city and what is the energy impact that urban mobility has within the modern cities.Innpulsa_Plan-Energetico-Murcia--ALEM- R4E

ALEM, the Local Energy and Climate Change Agency of the City of Murcia, under the Department of Urbanism, Environment and Huerta, directed by Antonio Navarro Corchón, was in charge of offering a complete vision of the Municipal actions in the matter of sustainable mobility, and it underlined the benefits that large municipal projects such as the Murcia Bike Lane project, the Local Electric Vehicle Strategy or the pedestrianization of the Avenue Alfonso X will report to the city. ALEM also took this opportunity to explain in detail the prospects and ambitions of Murcia regarding the smart mobility and introduced the “Roadmaps for energy (R4E)” project. Moreover, the key aspects of the project were presented as well as the methodology that the partners have followed to develop their roadmaps in the 3 focus areas of the project (smart buildings, smart mobility and smart urban spaces). In fact, the e-mobility strategy for Murcia has been one of the first outcomes of the R4E project in Murcia and will be the ground for other initiatives related to electro mobility in the city.Plan-Energetico-Murcia--roadmaps-for-energy_jaime_ruiz_huescar

It is noteworthy that all these projects have in common with the Energy Plan of the Region of Murcia that have been addressed and raised from participatory processes, they all have an integrative sense and have tried to involve civil society to meet the different needs and visions of the citizens of Murcia.


Tallinn Main Street

Tallinn Main Street.

For decades urban planning in Tallinn has been focused on motorised vehicles, mainly the private car. This has resulted in a congested, unpleasant and unsafe city centre for the people. Now, with Estonia’s centenary in 2018 and its presidency of the EU in the end of 2017, the city aims to change this notion by starting with the city centre and creating a 21st century Main Street.

spring in the city - TallinnVisualisation of the design ‘Spring in the city

Until recently city planners have added roads and widened streets in order to accommodate the increasing number of cars. Pedestrians and cyclist have been mostly allocated the narrow strips of streets that are left between buildings and car lanes. With the Project of the Main Street we will create a people-friendly 1,5 km stretch in the centre of Tallinn. The goal is to transform the heart of Tallinn from a transport corridor to a buzzing space with its own identity and street culture – a space for meeting and spending time, not just a busy thoroughfare for cars that citizens and tourists alike try to avoid.

By prioritizing public transport and increasing the pedestrian zones, the mobility of pedestrians and non-motorised vehicles will be improved. It will also mean fewer cars in the city centre, which will contribute to a decrease in traffic noise and improvement of air quality. In a few years the Main Street will also link the Old City Harbour with the city centre, making the seaside more easily accessible and turning the city into a true coastal city.

AUL visualisation- TallinnVisualisation of the design ‘AUL’ – how to connect the Main Street with the sea

The design competition, organized by the Estonian Centre of Architecture, took inspiration from sustainable city planning solutions in other European capitals, such as Berlin, London, Stockholm and Helsinki. The winning team in the design competition is led by Toomas Paaver from Linnalahendused, in cooperation with Kavakava Architects. Their project is called “Spring in the City”, which aims to highlight missing sections of the Bastion belt that used to surround the Old Town centuries ago, when Swedes ruled the capital.

The process of the Main Street project hasn’t been a smooth ride and a lot of efforts in communication have been made to inform the public about the benefits of such an endeavour. In 2015 there were 497 passenger cars per 1,000 inhabitants in Estonia, meaning city planning has mainly focused on creating a smooth traffic flow that’s comfortable for the drivers. Although the Main Street isn’t directly banning cars, a lot of car owners have expressed their concern about the project. However, more and more people are excited about the new Main Street, including local business owners, who expect increased sales with more pedestrians in the area. As Tallinn residents, we look forward to the new Main Street – a more vibrant city, with cleaner air to be enjoyed on foot.





Hyperloop proponents interested in Helsinki-Tallinn undersea route

Could Hyperloop be the next step towards Tallinn achieving their R4E objectives?

Hyperloop proponents interested in Helsinki-Tallinn undersea route

Hyperloop One is interested in the proposed undersea connection between Helsinki and Tallinn. A pod travelling at airplane speeds would reduce travel time between the two cities to just six minutes, and building it would be cheaper and could be done sooner, the company argues.

Vice president of Hyperloop One, Alan James, was in Estonia last week to introduce the project. According to him, their high-speed pod would be a perfect fit for the proposed connection across the Gulf of Finland. The connection could become the infrastructure project of the 21st century and had the potential to change the economic and political geography of this area, James said.

Hyperloop One could build this connection faster, better, cheaper, and more environmentally friendly, he added.


EU provides €1 million for Tallinn-Helsinki tunnel feasibility study

The Estonian transit sector is carefully interested, though they are not convinced that Hyperloop’s schedule is realistic. “If we’re only talking about passenger transport, then this is a very serious alternative to a tunnel between Tallinn and Helsinki,” CEO of AS Tallinna Sadam, Valdo Kalm, said. This mainly because the diameter of Hyperloop’s tube was much smaller than that of a railway tunnel, and because such a tube would likely be much cheaper to build.

“If we’re talking about getting to Helsinki in six minutes, I would extend this in the direction of Stockholm,” Kalm added.

At the same time, there is plenty of skepticism, especially where moving cargo is concerned. “Large goods will never be moved around by Hyperloop, or mass goods, there are so many technical reasons for that, and also financial ones, that won’t happen, so the railway isn’t out of the picture just yet,” transit expert and former chairman of the supervisory board of AS Eesti Raudtee, Raivo Vare commented.


According to Jüri Lavrentjev of the Tallinn University of Technology, there are additional problems. Beyond the fact that plenty of technological issues are not yet solved, there is also the aspect of security. If something were to go wrong in a Hyperloop tube, it would be a difficult problem getting to the passengers and rescuing them.

Tesla and SpaceX founder Elon Musk was one of the first supporters the project, which is currently looking for a first route. Hyperloop One has previously presented a first business case for a Stockholm-Helsinki connection that would reduce travel time between the two capitals to just 30 minutes. Other routes have been discussed, in Russia, China, and the United Arab Emirates as well as in other locations in Europe.


So what is a hyperloop?

In Musk’s words, a hyperloop is a system to “build a tube over or under the ground that contains a special environment.” Cars would basically be propelled in this tube. One example could be a huge sort of pneumatic tube where high-speed fans would compress and push the air — although the friction implications make Musk skeptical that it would work. Another option is having a vacuum in the tube and using electromagnetic suspension instead. Musk acknowledges it is hard to maintain a vacuum (one small leak in hundreds of miles of tubing, and the system shuts down), but there are pumping solutions to overcome this. He favors the second solution.


1) The passenger capsules aren’t propelled by air pressure like in vaccuum tubes, but by two electromagnetic motors. It is aimed to travel at a top speed of 760 miles per hour.

2) The tube tracks do have a vaccuum, but not completely free of air. Instead, they have low pressure air inside of them.Step2Hpl

Most things moving throughairtubes will end up compressing the air in the front thus, providing a cushion of air that slows the object down. But the hyperloop will feature a compressor fan in the front of the capsule. The compressor fan can redirect air to the back of the capsule, but mostly air will be sent to the air bearings.

3) Air bearings are ski like paddles that levitate the capsules above the surface of the tube to reduce friction.



4) The tube track is designed to be immune to weather and earthquakes. They are also designed to be self-powering and unobsrtuctive. The pillars that rise the tube abobe the ground have a small foot-print that can sway in the case of an earthquake. Each of the tube sections can move around flexibly of the train ships because there isn’t a constant track that capsules rely on.

And solar panels on the top the track supply power to the periodic motors.
With these innovations and completely automated departure system, Elon Musk’s dreams of the hyperloop being the fastest, safest and the most convenient form of travel in the world.

The City of Murcia has been working intensely since September 2016 in the development of this Strategy and it was in that month when the draft document was presented in a public event where many different stakeholders were called, such as car dealers, associations related to the sustainable mobility and various experts in the field. This event also meant the kick off of a participation process aimed to enrich and complete the draft document of the e-mobility strategy.

This process allowed the municipality firstly to request the collaboration of experts in sustainable mobility and the citizens of Murcia to assess the 33 measures included in the document and secondly to invite them to propose new measures and ideas for the implementation of these actions. The period of collection for contributions, their analysis and final wording of the document concluded in March 2017. The city of Murcia, through ALEM, will present in May the final document and the first measures to be implemented in order to foster and support the deploy of the electric vehicle in our city.

The 50 measures included in the strategy are the most important milestone with regards to policies of support to the electric vehicle realized until now in Murcia. Among these first measures of urgent implementation we can mention the creation of an EV charging network on the public road, the reservation of exclusive parking spaces for electric vehicles and exemption in the payment of the regulated municipal parking, measures that are already being studied by the department of Urbanism and Environment.

During this session, Jaime Ruiz also gave the key aspects of the “Roadmaps for energy” project and explained that the involvement of the Municipality in the project has triggered the development of the e-mobility strategy as the most important step taken towards smart mobility during the last years in Murcia.

How to organize the European Mobility Week

How to organize the European Mobility Week

On 20 & 21 March 2017, the City of Murcia participated in the workshops of the European Mobility Week Awards 2016 (EMW 2016). ALEM, the Local Energy and Climate Change Agency of the City of Murcia was responsible for sharing with other European cities the experience of the City on how to successfully organize the activities and events of the European Mobility Week. The European Commission engaged Murcia to be present in these workshops to provide advice and explain in detail their wide experience as organizer of the EMW editions. In this way, ALEM showed how they prepared the candidacy of Murcia to the edition of 2015, in which Murcia won the prize amongst more than 800 applications from all over Europe.

ALEM highlighted, among other aspects, the importance of organizing activities that have the citizen as the protagonist and in which people are actively involved. ALEM also pointed out that outdoor activities must be foreseen in order to enable citizens to enjoy the streets and the public space in a different and original way. During that week there are more opportunities for cycling and walking freely and you can enjoy the city in a full way leaving aside the car and the daily limitations.

EMW awards 2016- main session

The events held in the framework of these workshops also were useful to create new collaborative links between the City of Murcia and other European cities that also work intensely to place the sustainable means of transport such as the bicycle, walking or electric vehicle in the position they deserve and to guarantee the required municipal support to make them more relevant in our cities. In this regard, it should be mentioned that the Department of Urbanism and Environment has turned to support sustainable mobility by establishing important milestones such as the construction of 20km of new bike lanes In the city and the support to the electric vehicle, materialized through the creation of the Local Electric Vehicle Strategy to be presented soon.

Energy Certification of the “Poppy” Nursery in Palermo

Energy Certification of the “Poppy”  Nursery in PALERMO

The article describes the methodology developed to address the theme of energy efficiency in a municipal building, which is a reproducible example for the entire property estate of Municipality of Palermo. The study was carried out on a kindergarten, recurring type of construction in the municipal building park.

They started from the realization of an energetic diagnosis to the energy certification of the building, in line with the regulations in force in Italy (DM of 26/06/2015), to end with the proposition of interventions of energy efficiency to be realized on the “Poppy” nursery, located in Palermo, in the Borgo Nuovo district.

The study was carried out implementing the methodology described below consisting of the following actions:

  • an energy audit that made to understand the “state of the art” of the building, with regard to the constructive features of the “building-construction casing system”;
  • determination of primary energy requirements and corresponding CO2 emissions through the use of computerized computational models complying with UNI 11300 national standards issued in implementation of Community Directive 2002/91 / EC, also known as the EPBD Directive (” Energy Performance of Buildings Directive “) and those issued up to now;
  • energy certification of the building, culminating in the realization of the first energy plate of a communal building; first case in Palermo and one of the few in the south. This plate shows the energy class of the building and is a distinctive sign of its energy quality;
  • drafting of the energy efficiency project of the kindergarten in order to identify possible interventions to bring the building from the current class (C) to the highest efficiency class (A4). The implementation of the proposed interventions would make possible to transform the kindergarten into an almost zero energy building (NZeb). The necessary work, given the achievable energy class, could be realized using the funds provided in the “Thermal Account 2.0”, in force from May 31, 2016.

The building consists of a ground floor building with a total gross floor area of 355.72 m2, a total dispersing surface of 991.85 square meters and therefore with a shape factor equal to 0.59 1 / M. Its structure consists of a flat concrete slab covering, unobstructed masonry walls and a floor made of a lateral concrete slab on the nest. Transparent dispersing surfaces are made up of windows and window doors with a surface of approximately 60 m2, made of metal frames and single glazing with low thermal resistance.


The energy services present are: winter air conditioning, hot water production, summer air conditioning and lighting. The energy sources used are natural gas for winter air conditioning and electricity for hot water production, summer air conditioning and lighting; Part of the latter is satisfied with that one produced by a photovoltaic plant. The heating system consists of a standard base boiler with a nominal power output of 70 kW and steel radiators. The hot water generator consists of 3 electric storage boilers, with a rated load of 1.2 kW each. With regard to lighting, the census of the typologies and the number of light sources has resulted in an installed electric power of 4.32 kW. The cooling system, on the other hand, consists of 6 heat pumps, located in the most frequented environments, with cooling power ranging from 2.1 to 5.3 kW. The photovoltaic system, placed on the roof, has a power of 6 kWp.

Calculations were made for the determination of the non-renewable global energy performance index of EPgl, nn 222.5 (kWh / m²) and of the Global Energy Class, equal to C class.

At the same time, the energy diagnosis, that preceded the start of any energy efficiency project, with the acquisition and consultation of all necessary data, was carried out In order to understand how energy is used in the building and to identify any waste.

In addition to obtaining data on building envelope and air conditioning systems, all electrical equipment (fax, photocopiers, computers, etc.) and lighting fixtures have been registered, together with real energy consumptions, derived from monthly invoices for electricity and natural gas consumptions.

The set of data and information has been used to identify opportunities for building energy efficiency improvements.

The energy auditing phase ended with the analysis of  benchmarking index; this comparative benchmarking compares the energy consumption of a building with that one of similar structures, enabling evaluation of opportunities for improvement and quantifying the possibility of obtainable savings.

Subsequently, energy efficiency measures were considered, evaluating both the costs and the energy savings derived. For the choice of interventions, the critical points of the building were taken into consideration, that is, both the wrap elements and technical installations such as winter and summer air conditioning, hot water production and lighting. The following interventions have been suggested:

  • Ventilated roofing using wooden fiber insulation panels, modular scantlings (IGLOO) made of 17 cm    high plastic material, and on top a screed of lightened concrete with expanded polystyrene, 5 cm           thick. This package allows significant energy savings that would bring the thermal transmittance to     a value of 0.305 (W / m2K), lower than the legal limit, imposed by the DM. Of 26/06/2015;




  • Insulation of external masonry, carried out by applying a coat system with ventilation chimney on the          exterior, consisting of a 600 mm expanded polystyrene panel with a drilling system that            ensures the ventilation inside the insulator . The transmittance would pass from 1,024 (W / m2K) to       0.382 (W / m2K).
  • Replacement of all transparent structures with thermal cut PVC fixtures, Uw = 0,89 (W / m²K), and       double glazing with argon in the interspace (type 4-16-4), low emission, with thermal transmittance            Ug Ranging from 1.1 to 1.3 (W / m²K).

It is also expected to replace the existing boiler and individual heat pumps with a new air-to-air cooling air conditioning system for cooling and heating, consisting of a 28,00 kW cooling/cooling motor and 31.50 kW in heating and “lowered” canalized internal units for false ceiling installation. The old distribution system will not be taken into account. The plant will be sized to work for over 90% of the time at a load percentage ranging from 30% to 60%. Under these conditions, the motor-condensing unit will have an average COP and EER of more than 6.00 at nominal operating conditions.

Finally, for the needs of domestic hot water, a forced circulation system is foreseen. Consisting of a solar hot water tank with a primary circuit connected to two solar collectors. The energy collected from the solar collectors is sold through a heat exchanger to the water contained in the accumulation, while the circulation of the heat conductor is carried out by means of an electric pump controlled by an electronic control unit. The control unit stops the pump when the collector flow temperature is lower than that in the accumulator (eg during the night). In the days of no solar irradiation, the boiler ensures the supply of energy.


The total cost of the planned interventions is approximately € 86,450.00 and the EPgl index would not exceed 45,3 kWh / m2, in class A4. This value would allow access to the funding contained in the Energy Account Decree 2.0.

The economic evaluation of the energy efficiency measures was carried out by the determination of the return time (TRA), which is 8.3 years.
