It is a cohabitation between agricultural production and photovoltaic electricity production on the same surface.
Installation of solar panels on agricultural sheds as our project of: Construction of a single-slope metal agricultural shed in kit with a photovoltaic installation of 118kWp integrated into the roof connected to the electricity grid ENEDIS.
Marble technology is put in place, so that the implanted panels can be controlled in real time.
The structure of the hangar is built 4 or 5 m from the ground for the better circulation of agricultural machinery. Everything is installed in such a way that there is no impact on the environment, without concrete and without polluting the soil.
Generally speaking, farmland is far from the power grids, so with this solar power generation, it meets the energy needs of farmers. They are keeping their commitment to the energy transition.
The benefits of Agrivoltaism:
The control of the panels when there is too much sun for the plantations makes it possible to reduce thermal and water stress thanks to a shadow effect.
Improving product quality.
Installation of protective nets in the orchard: hail, insects, wind.
Protection from climate change.
Lengthening the life cycle of plantations, such as vines.
For more information, we invite you to join us on June 14-16, 2021 for the second edition of the “AgriVoltaics 2021” conference, presented by the Fraunhofer Institute, which through its ISE solar energy systems has created technological foundations to provide energy efficiently while respecting the environment.
AgriVoltaics 2021 aims to bring together the scientific community and establish international exchanges to advance technology.
Participate in conferences amplify our know-how and our savoir-être.

In 1997, Kyoto Protocol : Signatory countries commit to reducing greenhouse gas emissions, changing the climate. First, the control of energies, then renewable energies, such as solar, wind or biomass, but there is another renewable source, less publicized, although extremely effective, is geothermal.
From the Greek “geo” (earth) and “thermos” (hot), the term “geothermal” covers both the science that studies the earth’s internal phenomena and the industrial processes that seek to exploit it to generate electricity and/or heat.
Well, it comes from deep beneath the surface of the earth and it’s called geothermal energy and we can use it to generate clean renewable electricity. Ok, here’s how geothermal works.
Have you ever thought where all this heat comes from?
Heat from the earth’s crust warms water that has seeped into undergound reservoirs.
When the water becomes hot enough, it can penetrate the surface of the earth in the form of steam or hot water. This usually occurs when the Earth’s crust or “plates” meet and move.
Previously, the use of geothermal energy was limited to areas where hot water flowed near the surface. But as geothermal technologies progress, we can take advantage of these natural renewable energy sources even more.
Engineers have developed different ways to generate electricity from geothermal wells drilled into the ground.
The environnemental benefits of this clean, round-the-clock renewable energy source are substantial : low emissions, small physical footprint, and minimal environmental impact. The few by products that can come up are often re-injected underground.
Geothermal energy can also help recycle wastewater.
Geothermal energy is the exploitation of the heat of my Earth. The planet Earth, inside, is extremely hot, we have temperatures under a few tens of kilometers that reach 1200 degrees. That’s the temperature of the mantle. The deeper you dig in the earth, the higher the temperature increases, depending on the thickness of the earth’s crust.
For example, under Paris we reach temperatures of 70 degrees, around 1800m.
To exploit the hot water, two holes are drilled. The first one draws the fluid at a temperature of about 70 degrees. The other to re-inject it into the basement after extracting heat. This is the principle of the geothermal doublet, to which a heat exchanger is associated. You don’t send the heat directly into the radiators because the geothermal water, in fact, is often loaded with salts. However, heat is exchanged with a surface heat exchanger with the residential heat distribution network.
Under Paris we have this formation of the Dogger, it is a floor of the Jurassic, a limestone floor, which allows to heat directly because one reaches temperatures of 70 to 80 degrees, to heat directly housing complexes.
Home heating accounts for about ¼ of CO2 emissions into the atmosphere.
Heating is, precisely, the most natural application of geothermal energy. It is a heat exchange without chemical production.
The geothermal installations in Ile de France prevent an annual release of 340,000 tonnes of CO2. 1st renewable energy in the region.

In this time of Covid-19, the world’s largest exhibition of new technologies, the Consumer Eletronic Show (CES) took place online through live videos. From TV, smartphones to vehicles, autonomous cars, great projects were presented to show the future of technology. It is the place of demonstrations where all professional or private people get inspiration and a desire to contribute to the realization of innovative projects.
Indeed, the fact that we are in a time of pandemic has changed the way the show is presented, but that’s not all, this crisis pushes many researchers to find solutions for all. We must remember that these solutions are being developed.
Have you heard about the new typology of masks, disinfectants and air purifiers to combat Covid-19 ? Indeed, Alarm.com has created a contactless video bell to reduce the transmission of bacteria, it is a project that can be very useful for everyone and to adapt in homes. Also, more and more robots are created to project ultraviolet light in order to disinfect places likely to have people, such as shops, restaurants, etc. But at this show what was most highlighted was the AirPop Active +, it would be a smart mask with an integrated sensor that tracks our breathing and evaluates air quality to replace the filter of our mask if it is deemed replaceable. These masks will be on the market this month. This solution is one of many, because engineers also contribute to the fight through air filtration. The impression that this period will never stop, gives a lot of ideas to the engineers. For example, integrating an anti-covid system into our bathrooms as shown by Kohler who has built toilets that can be activated by simple movement of the hand is a project that also prevents the transmission of bacteria.
Euroelec-Smart Energy to fight against this virus, has promoted teleworking for all employees by being present H24 in videoconference to keep the contact between us, present also on social networks to talk about our news and online with our professional contacts. We are also interested in the innovative solutions that we will put into our construction projects.
We are obliged to tell you about the solar remote control created by Samsung. This is the remote control of the Samsung Neo QLED TV, which integrates a photovoltaic cell and thus allows it to recharge to the interior and exterior light. Of course, this solution is of particular interest to Euroelec-Smart Energy because photovoltaics is one of our biggest specialties.
Photovoltaics is the process that directly transforms the energy of the sun into electricity. This is a good investment in the long term and avoids the waste of AAA batteries. Solar is also an advantage, it contributes to the reduction of CO2 emissions, the reduction of polluting releases and the preservation of natural resources, then, photovoltaic energy is scalable and allows to meet all the needs.
Light is at the centre of innovations. Also, Mary Barra, CEO of General Motors at CES 2021 announced two new concepts : the autonomous electric car Cadillac Halo and a flying taxi. It is true that this project gives the impression that it comes straight out of a film by Luc Besson but that is what makes it the importance of this innovation.
This car is called autonomous by the artificial intelligence directly integrated. Everything is controlled by voice and gestures, no physical button appears. This concept is a springboard to technological progress.
As for the flying taxi, it might be hard to believe but it is an adav, a vertical take-off and landing aircraft powered by four electric rotors totaling 90 kWh for a maximum speed of 90 km/h. It is a concept mentioned but not yet developed despite a large number of people ready to invest in it.
In conclusion, the Best Innovation 2021 award went to the great Sony for its « Spatial Reality Display » project. This 15.6-inch display contains a 360° speaker and an Airpeak drone. It is a product that makes lovers of visual and digital creations dream because the goal is to project us through this screen in a real world.
The screen returns a 3D spatial reality display without glasses that is already popular with large groups such as Volkswagen.
Indeed, Euroelec-Smart Energy has looked at this project, as it can be useful as a design tool. The BIM or REVIT software, allow us to optimize the design, the construction. But with the « Spatial Reality Display », this would allow us to get even more visibility and visualize our designs in augmented reality.
https://www.euroelec-smartenergy.com/wp-content/uploads/2020/05/logo.png00SuperAdminhttps://www.euroelec-smartenergy.com/wp-content/uploads/2020/05/logo.pngSuperAdmin2021-01-21 14:17:172021-01-21 14:17:19Innovation: The key to Euroelec-Smart Energy’s objectives
At Euroelec-Smart Energy, our employees use innovative IT tools for their functions and rendering.
We set up training courses for everyone, in order to improve on the computer software used, but also to become more competent to offer you our project management services.
Euroelec-Smart Energy implements the practice of BIM. But what is BIM? Building Information Modeling in English, makes it possible to draw, implement, make calculations to verify the sizing of equipment and become more efficient in terms of compliance. Among other things, it is a digital model composed of parametric objects, which aims to optimize the design, construction, operation and collapse of buildings.
This method of work allows us to follow the construction phases of a project from A to Z, through the distribution of tasks.
But drawing in real size, is not the only function of this software. Also, we use it to help us in the realization of structural calculations, detection of problem at risk and thus allow a detailed analysis by visualizations.
As for Revit, it is a CAD (computer-aided design) software, dedicated to BIM, which belongs to the American company Autodesk (publishing company of creative software and digital content, also creator of the famous AutoCAD software). It allows us to create, design and imagine 3D projects and then bring a large part of the documents necessary for its realization.
This software is used to model buildings in 3 dimensions and works with a single file that contains all the data. That is, when an item is moved or changed function, Revit updates it in all views of the model. It also makes it possible to interact with several disciplines such as networks, fluids, structure, and this is what we set up at Euroelec-Smart Energy.
It is a stand-alone software that works both in cut, plan, perspective, facade, 3D cut, orthogonal view and nomenclature.
When working on this platform, it is possible to export the models in 2D and 3D file, so the models can be compatible for other software such as AutoCAD.
At Euroelec-Smart Energy, our designer/designer, allows us to analyze and control through visualization for the study of a project, in order to obtain a qualitative result and avoid any risk, that is, to provide security to the field teams so that they work in good conditions by detecting risks upstream. Thus, we put forward our technicality, presenting quality renderings.
“slide left to see more”
Our studies of plans, calculations are also done by AutoCAD, a computer-assisted drawing software. It is by its wide choice of tools that we can realize all types of buildings and fittings.
For example, thanks to this software we were able to carry out the plans and calculations for a villa construction project in Switzerland, project respecting a Minergie P standard (building with very low energy consumption) with maximum energy autonomy.
The missions were:
-The realization of thermal calculations SIA380/1 “Minergie P” on the software Lesosai, software of certifications and ecological and energy balance of buildings.
-Calculations and dimensioning of the installation, distribution and emission, of geothermal sensor coupled to two heat pumps for the production of hot and cold.
-And the study and design of the distribution of domestic hot water through the installation of solar thermal panels.
It is important for our design office to carry out projects of exceptions while highlighting our values respectful of the environment. The software used and our project achievements allow us to participate in green growth by better controlling its energy consumption.
BIM BIM changes the way contractors, architects, engineers and contractors work. With this model, they can add more information at the beginning of the project and before the changes are made.
Real estate construction does not escape the major innovations generated by design software. The Building Information Modeling BIM is a means of developing, implementing and monitoring construction projects.
This practice is done in five levels of detail starting with the sketch at the building. Because to arrive at a perfectly finished model, it will take a lot of time to model it and count long hours of design. It should be noted that the BIM model is built according to the contribution of the different stakeholders on the work, from the design to the construction. This will allow the different employees to anticipate, optimize and better represent their choices during this time.
Euroelec-Smart Energy through the BIM digital model will reduce the risk of errors that can be committed on a construction site, obtain better collaboration with stakeholders and have a better quality of projects.
The BIM is in fact a database management system, since it makes it possible to inform the project managers on the situation of buildings, premises, offices, shops, to locate the equipment and construction products with their data. Also, to identify the surfaces, to facilitate the supply of the forecast management and to know the frequency of the activities of maintenance of the assets and many other functions.
For Euroelec-Smart Energy, it is an inevitable practice to design, maintain and renovate buildings.
Our objective is to:
The LOD style
Le style LOD définit par The American Institute of Architects dans le « Building Information Modeling Protocol Form » permet de qualifier le niveau de précision d’une maquette.
Illustration of the development levels defined by The American Institute of Architects:
For example, for our villas renovation project in Ibiza, Spain, we were in phase 300. (Phase explained below).
LOD 300 – Precise geometry The model element is graphically represented in the model as a specific system, object or assembly in terms of quantity, size, shape, location and orientation. Non-graphical information can also be attached to the template element. The origin of the project is defined and the element is precisely located with respect to the origin of the project.” UNITED-BIM INC.
CONSTITUTION OF THE DIGITAL DOE
The implementation of works is done by the DOE, (Dossier d’Ouvrages Exécutés Numérique) which is the compilation of all technical, written and graphic documentation. This is what will be handed over by the supervisor to the owner. A verification and VISA procedure is mandatory for each DOE to ensure that everything is in order. It includes the drawings conforming to the execution, the calculation notes, the technical checks, the operating instructions and the quality of the materials used.
BIM: INTERNATIONAL COMPARISON
Internationally, and more specifically in the United States, the improvement of constructions is essential for the efficient research of economic performance of construction sites. As for France, this improvement appears during the internal management of stocks in companies by finding solutions for a possible change in materials prices. It is here that the BIM intervenes, because it is the latter that will allow this realization through computer software to find precisely the implementation of the various components.

For some, we are slaves to our routine, our habits and our brain is content to save energy by simplifying our lives.
So how do we change a paradigm, a routine, and a habit?
This question has been studied by neuroscientists, psychologists who for them this last one is of great complexity, since it is important to put aside laxity (carelessness) but rather to create a new way of life by our emotional and technical side.
It is true that we are all responsible for our habits and it is up to us to find solutions.
To achieve change, we need to identify our routine, create rules, alternatives, strategies and ensure proper execution by developing a plan.
For mistakes that can be made, they increase with the degree to which we are distracted, stressed or somehow mentally overwhelmed. We are more sensitive to the emotions guiding our attention when our mind wanders. Absolute concentration demands that our inner voices be silent.
What we learn at Euroelec-Smart Energy by Lean Management is to think before taking action. Because yes, we all want to do well as soon as possible, but rushing into a project does not guarantee a quality result. This collective act of self-awareness will, on the one hand, allow cohesion, but also save considerable time for the progress of our projects. Among other things, unconsciously it would be a collective coaching because all reflect periodically on its functioning as a group to promote the expected change. The goal is to create a positive atmosphere.

The applications of Lean are diverse and varied, and that’s what we implement at Euroelec-Smart Energy by training our team on this process. It allows us to minimize waste by not overloading our project stakeholders.
It was in 1910-1938 that Henri Ford and William Edward Deming set out 7 principles of LEAN with the aim of applying them in several sectors, such as the automotive industry, aeronautics and other engineering.
For greater precision, these are the elimination of waste, flawless production, the « Just in time », the reduction of fluctuations, the continuous improvement, the standardization of work and the involvement of operators. All this to save considerable time to the good production of the tasks to be performed.
At Euroelec-Smart Energy, five members of our team have been unanimously designated as the pillars of five LEAN principles.
–The human system, the one that will maintain “order” in the team, and manage relationships.
–Standardization for the organisation and internal management of company files.
–The quality of the documents in appearance.
-The “Just in time” to manage schedules and deadlines.
–Continuous improvement to go further and evolve.
I- Qality control
First, different visions of a society may appear. An external vision by the customers by not noticing any defect of the latter, and an internal vision of the employees not perceiving zero touch-up. And this is to be modified by different tools because do not notice that the good will not advance a company in the right way.
The most widely used method of quality control is the “Poka Yoke“, which prevents errors in the results of the project. But control does not do everything, while DOING quality is doing a good deed the first time.
B) At Euroelec-Smart Energy
At Euroelec-Smart Energy we practice JIDOKA, it is a technique that detects defects as soon as possible so as not to lose productivity. For example, if we find a problem on a project, we will investigate the problem as soon as it occurs, which will allow us to find an immediate solution or alarm the collaborators about the malfunction.
C) Visual Management
Presentation of two publications from our Instagram @euroelecsmartenergy where we apply LEAN for the reorganization of our Parisian premises. This is an example to show that this process allows to visualize the changes in one before/after and to realize that a simple change can make a business more efficient.
Euroelec-Smart Energyis one of the first energy design offices in Paris to implement LEAN.
II- Eliminating waste
A) Muri, Mura, Muda
The 3M technique is a Japanese method that increases productivity by eliminating waste in a concrete way. These are three forms of waste that are present not negatively but positively in a company because they are the triggers for the acquisition of profits.
These terms come from the Toyota Production System Transcript, created in 1988.
Muri,it is an overload on the human level, this can be due to an intense workload that causes stress on employees.
Mura is managing the fluidity of production if it becomes too powerful.
Muda is reducing “unnecessary” things to save time.
B) “Just in Time”
Waste is a cost to the company, for example, if we have a good organization, the time we waste searching for documents would have been kept to continue carrying out projects.
The goal is to produce what the customer needs when they need it.
C) Our challenges at Euroelec-Smart Energy
We are putting in place challenges to evolve our design office. Our objective is to identify for 15 days problems that affect the overall quality of our work and the company. Identify the 7 waste and find somes solutions.
III- Continuous improvement
This method is fundamental to the application of LEAN Management within a company. Its role is to improve the internal and external working environment to avoid inefficiencies.
By being precise, unnecessary objects must be removed either by storing them or by throwing them away. For example, sheets placed on a table that are of no use take up space on a work desk and can become awkward, which is similar to the second “Locate/Store” S.
Cleaning tools and ensuring their proper functioning, is the best way to avoid a defect and therefore a waste of time for their use.
At Euroelec-Smart Energy, standardization has been assigned to an employee to make the place of each object obvious and easier to locate in our research. We created color codes to differentiate each project, and a better organization of our files by specific locations.
And then, the last S is to follow the previous S to ensure a better application of our work.
It is essential to implement this philosophy of “small steps” because if there is a rush in our tasks, there is a risk brought about in terms of quality control.
It is better to start with the creation of precise and simple innovations than to think too large from the beginning.
UNDERSTANDING this LEAN approach is the key to differentiating from other companies, and maximizing its output.
