The Michelin Green Star: Where Gastronomy Meets Sustainability

While the transportation sector accounts for nearly 30% of CO&#178; emissions in France, rethinking how we move has become a climate emergency. And this shift also involves… the choice of our future dwelling.Sustainable Mobility: What Does It Mean?Sustainable mobility encompasses all means of transportation and behaviors that reduce the ecological footprint of our journeys. It is based on three main principles:• Reducing the use of individual cars in favor of public transport, cycling, or walking.• Promoting clean vehicles, such as electric cars, by facilitating access to charging stations.• Considering accessibility as a central criterion in urban planning and housing choice.In summary, it's about moving differently, less often, and better.Sustainable Housing and Soft Mobility: An Inseparable DuoAt Sustainablerealestate.fr, we carefully select properties for sale or rent that incorporate this expanded vision of sustainability. We particularly focus on:• Residences near public transportation: train stations, metro lines, trams, or buses within walking or cycling distance.• Properties equipped with electric charging points, either individually or collectively, to smoothly transition to electric vehicles.• Neighborhoods designed for active mobility, with bike lanes, safe sidewalks, and simplified access to essential services.Because a well-located residence allows one to reduce dependence on cars without sacrificing quality of life.Why Is This Important?Choosing a dwelling designed for sustainable mobility is an environmental gesture… and much more. It's also about:• Saving time in everyday life with shorter or smoother commutes.• Saving money by reducing fuel, maintenance, and parking costs.• Improving quality of life by avoiding the stress of traffic jams and favoring gentler modes of transportation.It ultimately allows us to envision a more resilient future, where the city adapts to its inhabitants as much as it encourages them to adopt more responsible practices.What's Next?The transition to more sustainable mobility requires the involvement of all: governments, businesses, citizens… and real estate actors. By showcasing properties that promote these lifestyle changes, Sustainablerealestate.fr fully plays its role in this transformation.We believe that sustainable housing goes beyond its walls: it extends to everything around it. And because every journey matters, every property that facilitates soft mobility is an additional building block in creating a more breathable future.

Sustainable Mobility and Eco-friendly Housing: A Shared Vision of the Future

When it comes to real estate regulation, being attentive is anything but a luxury. This year is no exception to the rule... On the agenda: reforms but also renewal, to break free from a rather gloomy context. However, the plans outlined in the 2025 Finance Bill were disrupted at the end of 2024, by the vote of no confidence on December 4, 2024 which was set to overthrow the government of Michel Barnier.&nbsp;The uncertainties that resulted from this were partially resolved at the beginning of 2025. However, further details are expected regarding the real estate market: from rental investment to primary residence acquisition, from energy renovation to housing assistance, from changes in taxation to the forms to fill out for any renovation project.2025, a greener year? It seems so, especially in the field of ecological transition. In building decarbonization, there are few changes in 2025: the key points to note.🪫Énergy: anticipated changes·&nbsp; &nbsp; &nbsp; &nbsp;The absence of a Finance Act, the halt of Russian gas transit through Ukraine, and the breakdown of a major gas liquefaction plant have generated new factors of uncertainty in energy price evolution. &nbsp; &nbsp;·&nbsp; &nbsp; &nbsp; &nbsp;Energy performance of buildings: new adjustments to the RE 2020: A decree amending the energy and environmental performance requirements under the new building environmental regulation (tertiary housing) known as RE 2020 was published on December 31, for implementation on January 1, 2025. This follows feedback from the construction sector after two years of applying the regulation.&nbsp;&nbsp;·&nbsp; &nbsp; &nbsp; &nbsp;CEE: launch of the Pacte Entreprises program led by Ademe &nbsp;A decree, published on December 31, 2024 in the Official Journal, establishes the Pacte Entreprises program, eligible for energy efficiency certificates (CEE). Led by the Agency for Ecological Transition (Ademe), it targets private companies with tertiary activity buildings, mainly small and medium-sized enterprises, whether subject to the 'eco tertiary energy' scheme or not. &nbsp; &nbsp;🌡️ Climate objectives&nbsp;&nbsp;Adopted in 2021, the Climate and Resilience Law aims to combat climate change. To this end, it advocates and imposes objectives of Net Zero artificialization and energy renovation. Housing, food, transportation, consumption: every socio-economic aspect is subject to targeted measures, including within companies.Main objective: reduce France's greenhouse gas emissions by 40% by 2030 compared to 1990 levels.In early February 2024, the European Commission proposed an intermediate target: -90% by 2040. However, this has not yet been definitively adopted.The European climate regulation also establishes the creation of an advisory scientific council. Comprising 15 experts, it identifies actions to be taken to achieve the EU's climate objectives. And assesses the compliance of European legislative initiatives with the ambitions set out in the Green Deal and the Paris Agreement.According to the European People's Party, the European economy will depend on the abolition of renewable energy targets and the suspension of rules related to supply chain reporting.💶 Rental investment: G-rated DPE housing units prohibited for rentThe measure was announced as part of the 2022 Climate and Resilience Law.&nbsp;Its objective? Accelerate the energy transition by offering a greener, less energy-consuming rental stock.Since January 1, 2025, the die is cast: housing units classified as "energy sieves" due to their very poor energy performance are finally prohibited for rent.&nbsp;Concretely, a landlord can no longer offer a G-rated DPE housing unit for rent in mainland France. In the overseas territories, this measure will only take effect on January 1, 2028.&nbsp;Note: a G-rated unit under lease remains valid until expiry. However, without energy-efficient work, a new lease will no longer be possible.&nbsp;🗓️ The schedule:<ul><li>DPEs conducted before July 1, 2021 become obsolete due to the new rules.</li><li>As of January 1, 2025, co-ownerships with more than 50 units must compulsorily carry out a collective DPE (energy performance diagnosis).</li><li>In 2025: prohibition of renting G-rated DPE housing units.</li><li>In 2028: prohibition of renting F-rated DPE housing units.</li><li>Starting in 2034: prohibition of renting E-rated DPE housing units.</li></ul>&nbsp;&nbsp;&nbsp;&nbsp;💡 Mandatory energy audit for E-rated properties as of 2025From January 1, 2025, owners of properties rated E on the Energy Performance Certificate (DPE) must conduct an energy audit before selling. This measure, introduced by the Climate and Resilience Law, aims to encourage energy renovations in homes in France. Discover the details of this obligation and its impact on the real estate market.&nbsp;Ø&nbsp; What is an energy audit?The energy audit is a thorough analysis of a property's energy performance. Unlike the DPE, which is limited to an overall diagnosis, the audit provides a concrete work plan to improve the energy rating.&nbsp;&nbsp;Ø&nbsp; Which properties are subject to the energy audit?As of January 1, 2025, the energy audit applies to all E-rated properties put up for sale, in addition to F and G-rated properties already subject to this requirement.§&nbsp; Individual houses§&nbsp; Monoproperty buildings. Condominiums are exempt from this requirement, but remain subject to other energy renovation rules.<figure data-trix-attachment="{&quot;contentType&quot;:&quot;image&quot;,&quot;height&quot;:2,&quot;url&quot;:null,&quot;width&quot;:606}" data-trix-content-type="image" class="attachment attachment--preview"><img src="null" width="606" height="2"><figcaption class="attachment__caption"></figcaption></figure>Ø&nbsp; Why is this measure important?The aim is to reduce these properties known as thermal sieves, as they are energy-intensive and harmful to the environment.

What has changed as of January 1, 2025

According to the latest report from the IPCC (Intergovernmental Panel on Climate Change), a UN body, "this year should be the one where emissions peak if the world wants to have a chance of keeping the temperature rise within the range of 1.5 to 2 degrees Celsius, as recommended by the Paris Agreement."Regarding greenhouse gas emissions, the peak would be reached this year, theoretically, if the said agreement is respected.&nbsp;During COP 29 in November 2024, the focus was on financing climate action.&nbsp;This major event brought together nearly 200 countries in Baku, Azerbaijan.It was an opportunity for the European Commission to establish a new roadmap regarding the partnership for methane reduction to accelerate the reduction of emissions linked to fossil fuel production and consumption. Everything relies on collaboration between partner countries, the International Energy Agency, and several non-governmental organizations.&nbsp;This partnership represents a model of cooperation between fossil fuel-importing and -exporting countries. This will help companies improve their monitoring, reporting, and verification systems to reduce methane emissions.According to Wopke Hoekstra, Commissioner for Climate Action, "Reducing methane emissions in the energy sector is an easily achievable climate action goal. It's a matter of economic common sense. It contributes to strengthening our energy security while reducing emissions. The roadmap we are launching today shows the way forward for cooperation between importing and exporting countries. For the EU, it is clear: we can effectively reduce methane emissions only if we work together on global supply chains with all relevant parties."As part of the <a href="https://www.globalmethanepledge.org/">global methane commitment</a> launched by the EU and the United States, over 150 countries aim for a collective target of reducing global anthropogenic methane emissions by at least 30% by 2030, compared to 2020 levels.&nbsp;This new roadmap outlines a system of monitoring, reporting, and verification based on the principles of the Oil and Gas Methane Partnership 2.0 (OGMP 2.0), as well as a project to reduce emissions from assets.

From the Kyoto Protocol to COP 29: Progress and Developments

1 - WHAT IS IT?The RE 2020 is a regulation aimed at significantly reducing energy consumption by imposing strict standards on insulation, ventilation, and heating and cooling equipment. It reduces their climate impact by taking into account greenhouse gas emissions over the entire life cycle of buildings.The RE 2020 promotes innovation by integrating at least one renewable energy source in construction and the use of sustainable building materials. This regulation improves the living comfort of occupants through enhanced thermal and acoustic insulation and by making homes more pleasant to live in during summer by adapting them to future climatic conditions through better thermal comfort design.Indeed, the RE 2020 (Environmental Regulation 2020) replaces the RT 2012 (Thermal Regulation 2012) and complies with the Energy Transition Law for Green Growth (LTECV 2015) and the Housing, Planning and Digital Evolution Law (ELAN 2018), thus contributing to the reduction of greenhouse gas emissions and the fight against climate change.2- SINCE WHEN?As of January 1, 2022, the RE 2020 applies to the construction of buildings and parts of buildings such as extensions, for residential use, that are the subject of a building permit application or a prior declaration of works. Therefore, in 2024, the RE 2020 is in force and mandatory for all new buildings.3- CONCRETELY?The RE 2020 generalizes Positive Energy Buildings (BEPOS) and Passive Energy Buildings (BEPAS). It introduces the concept of Life Cycle Analysis of materials (LCA), by favoring the use of bio-sourced and low-emission materials such as wood for construction, in order to minimize energy consumption. The RE 2020 is a new standard aimed at building positive energy homes (producing more energy than they consume) and passive houses (spending very little energy and recycling what they produce).Passive housingA Passive Energy Building, BEPAS, is a building that meets minimal energy consumption and has reinforced air tightness with enhanced thermal insulation. The RE 2020 mandates the construction of passive buildings that produce as much energy as they consume. Therefore, the energy consumption of the housing per square meter is very low, even zero, and entirely offset by solar or geothermal contributions.The priority is to reduce thermal losses. To achieve this, its heating consumption must be less than 15 kWh/sqm per year (for renovations, it goes up to 25 kWh/sqm per year), and its total energy consumption must be less than 120 kWh/sqm. The Passive Energy Building relies primarily on excellent insulation of walls, such as walls, roof, and floor. Its air tightness is optimal.It should be noted that the BEPAS label certifies high energy performance for a home, significantly reducing heating and air conditioning bills for residents.Positive Energy HousingAlso known as BEPOS, a Positive Energy Building must generate more energy than it consumes and be energy independent.To achieve this, its heating consumption must be less than 12 kWh/sqm per year, and its primary energy consumption must be less than 100 kWh/sqm. The housing must be able to produce energy for its energy balance to be positive (heating, lighting, hot water, heat/cold recovery, and electrical appliances).Solar panels, a solar power plant, a wind turbine, or any other system that can produce its own energy in excess can be used to build a Positive Energy Building. It should be noted that the surplus electricity can either be stored or sold back to the EDF electricity grid at the prevailing purchase price.The RE 2020 regulation evolves the construction standards of new buildings by promoting energy sobriety and efficiency, reducing the carbon impact of new building construction while improving the comfort of residents.4- WHAT NEEDS TO BE DONE?The RE 2020 regulation evolves the construction standards of new buildings. Renewable energy production must at least cover the building's needs to make it self-sufficient, or even exceed these needs.For housing to reduce its primary energy consumption, excellent insulation of walls combined with a better choice of materials will also improve the residents' quality of life.To make housing energy-producing, the optimization of the housing's free energy sources, such as the sun, is necessary. To build a positive energy house, photovoltaic panels or a wind turbine can be used to produce electricity. Wood heating, solar heating, heat pumps, and geothermal energy for heating, solar water heaters for hot water. Finally, for water, rainwater recovery, water treatment, and water softener.5- THE ADVANTAGE FOR ME?With the implementation of the RE2020, we as individuals and citizens are encouraged to consume less energy. Technological advancements that reduce the consumption of our equipment alone are not enough to achieve zero energy waste. Acquiring an apartment or house subject to the RE 2020 regulation is a responsible, comfortable, and profitable choice.Profitable because it effectively reduces primary energy bills, or even produces a surplus when energy is produced and sold.First-time buyers can also benefit from the Zero Rate Loan (PTZ), which allows financing up to 40% of the property amount through an interest-free loan. The PTZ is subject to two criteria: household income and the geographical location of the housing.Reduced notary fees, between 2 and 3% of the acquisition price.Furthermore, if the energy effort was primarily borne by the new real estate sector until now, the old sector should soon be directly involved. It should be noted that properties classified as F in the energy performance diagnosis will no longer be able to be rented out from 2025. This directly affects property owners.At the same time, we all stand to benefit from the decarbonization of buildings, especially in terms of health, reducing energy bills, and saving costs in the system.

What is the RE 2020?

WHAT ARE THE BENEFITS?The certification evaluates the environmental performance of a building taking into account various criteria such as energy performance, water management, greenhouse gas emissions, indoor air quality, use of sustainable materials in construction, and waste management. The surrounding landscape and green spaces, utilization of innovative processes, and transportation are also factors taken into consideration.These performance indicators allow for a precise measurement of the sustainability of a construction project and its impact on the environment.To obtain BREEAM certification, a team of experts will assess the new building by measuring ten factors, including:Energy: Lighting systems, heating, ventilation, household appliances, and information technology equipment will be analyzed to assess the building's energy consumption. Potential sources of energy efficiency improvements may also be identified based on consumption data.Water: Plumbing systems, rainwater harvesting devices, and wastewater management will be used to evaluate water use in the building.Construction materials: The sources of materials used, their lifespan, and construction waste management constitute recycling. Their reuse establishes the building's durability.Greenhouse gas emissions: Or the management of building pollution sources. Examination of emissions related to building activities, occupant travel, and energy consumption is considered.Occupant health and well-being: Outdoor and indoor air quality are analyzed through ventilation systems, products used in construction and design, as well as indoor air quality monitoring measures. The importance of sound insulation to reduce external noise and respect the comfort of residents is noted.Landscape and ecosystem around the building: This involves evaluating the ecological impacts of the site on its environment. Management of green spaces, biodiversity, waste recycling, and measures to adapt to climate change are considered here.Another criterion for eco-responsible and certified housing is access to sustainable transportation around the site.CONCRETELY FOR ME?By promoting the design and construction of more environmentally friendly buildings, BREEAM certification helps reduce the ecological footprint of real estate projects by offering solutions to reduce energy consumption. These measures not only have a positive impact on the environment but also significantly decrease the energy bills of the inhabitants of these homes.By considering factors such as indoor air quality, green spaces, or natural light, certified buildings offer a more pleasant and healthier environment, influencing the well-being of their occupants who benefit from high-quality housing. These homes will enjoy better financial value, being more attractive on the market for both sale and rental in the short and medium term.Furthermore, BREEAM certification complies with local and national environmental regulations, promoting a long-term vision for tenants and a sustainable real estate investment for owners.It guarantees the commitment of real estate developers to environmental protection, as well as the satisfaction of international environmental performance standards. Over 600,000 buildings (residential, commercial, industrial, educational, or healthcare) have been certified in more than 89 countries with an expected annual growth of around 15%.

WHAT IS BREEAM CERTIFICATION?

The beautiful Pinel Law is a real estate tax exemption product created in 2014. It allows for a reduction in income tax of up to 21% of the value of a newly acquired rental property. You can earn rental income and also benefit from a tax reduction spread over up to 12 years, potentially saving you up to 63,000 euros in taxes. The scheme will end on December 31, 2024&nbsp;1- What is it?&nbsp;You benefit from a tax reduction if you are fiscally domiciled in France and have made eligible real estate investments under the Pinel law.&nbsp;Created to support investment in rental real estate, this scheme allows the buyer to reduce their income tax amount if they acquire a new or off-plan (vente en l’état futur d’achèvement - VEFA) property between January 1, 2014, and December 31, 2024.&nbsp;The tax reduction applies if the property is rented out for a minimum period of 6 years, and by respecting the investment ceilings per fiscal household, i.e., up to two investments per year.&nbsp;It aims to support rental supply in areas where demand exceeds supply and to offer properties with capped rents to households facing difficulties in accessing the housing market but not eligible for social housing.&nbsp;2- What are the benefits of the Pinel law?&nbsp;Reduce income tax&nbsp;The acquired property must be rented out for a duration of 6, 9, or 12 years. Based on this duration, the income tax reduction rate varies.&nbsp;Rent to family members&nbsp;With this scheme, you also have the option to rent out your property to your ascendants or descendants. The tenant can be your child or parent as long as they are not part of your fiscal household. Their reference fiscal income must not exceed the regulatory ceilings.&nbsp;Become a property owner without a down payment and build a real estate portfolio.&nbsp;3- How to benefit from it?&nbsp;All taxpayers can invest in the Pinel Law. You just need to meet 2 conditions:&nbsp;• Have your tax residence in France&nbsp;• Investment ceiling per fiscal household, up to a maximum of 2 investments per year (300,000€ at a price of 5,500€ per square meter).&nbsp;Properties eligible for the Pinel scheme are subject to rent regulation, meaning that a calculation is carried out to determine their price. Rent amounts are determined based on 3 criteria:&nbsp;• Investing in a property located in an eligible Pinel zone&nbsp;• Respecting the predefined rent ceilings in the zone where the property is located&nbsp;• Habitable surface area of the property.&nbsp;4- What are the conditions?&nbsp;The tax reduction applies to operations carried out between September 2014 and December 31, 2024, on properties meeting the following criteria:&nbsp;- New, under construction, having undergone renovation or rehabilitation works, off-plan (VEFA).&nbsp;- The property must be rented out unfurnished for primary residence use for a minimum period of 6, 9, or 12 years.&nbsp;- The property must be rented out within twelve months following the completion date of the property.&nbsp;- Compliance with rent ceilings per square meter varying by zones,&nbsp;- Rent to tenants whose annual resources are below a ceiling set by decree.&nbsp;- The property must comply with energy and thermal standards.&nbsp;- Located in an area where demand for rentals exceeds supply.&nbsp;There are three so-called "tight" zones. Zone A bis: Paris and its immediate suburbs (76 municipalities in the Île-de-France region) Zone A: Cities spread across regions (including Lyon, Marseille, Montpellier, Lille, Bordeaux…) and 650 municipalities in the Paris metropolitan area. Zone B1: all metropolises with over 250,000 inhabitants (Nantes, Grenoble, Reims…) as well as the outer suburbs of Paris.&nbsp;It is worth noting that since January 1, 2021, the Pinel law only applies to properties located in a collective building. It no longer applies to individual and detached housing.&nbsp;5- Changes in 2024?&nbsp;The Pinel scheme was extended in 2020 for the period from 2021 to 2024. This extension notably includes a reduction in the tax reduction rate. In 2024, the tax reduction provided by the Pinel law is 9% for a 6-year commitment, 12% for 9 years, and 14% for 12 years.&nbsp;In parallel with the current Pinel scheme, since January 2023, the Government has opted for the introduction of an enhanced scheme, the Pinel Plus, which will accompany the Pinel law until its end and allow its beneficiaries to continue enjoying the full tax advantage, which can reach 12%, 18%, and 21% by complying with the new energy and thermal standards for properties from January 2025.&nbsp;To benefit from it, you must acquire a new property with very good energy performance, complying with the RE2020 regulations on environmental standards related to building construction as of January 2025.&nbsp;Or choose to acquire a property located in a neighborhood designated as a priority area by urban policy, i.e., urban territories considered priorities due to their socio-economic situation (high unemployment rates…)&nbsp;So, classic Pinel or Pinel Plus?&nbsp;It depends on the property purchase date. Before December 2022, it is the Pinel scheme.&nbsp;Rent and tenant resource ceilings remain the same in both options, and it is still the rental duration - 6, 9, or 12 years - that will define the amount of the tax reduction.&nbsp;The difference lies in the introduction of more responsible housing on the market. Thus, under the Pinel scheme, the property owner can benefit from a tax reduction of up to 4,500€ per year, which differs from Pinel Plus, where the tax reduction can reach 6,000€ per year.&nbsp;6- How does it work?&nbsp;The Pinel Law limits investment to 2 properties per household per year.&nbsp;The tax reduction calculation is based on a maximum acquisition amount of 300,000€ per year and within the limit of a price of 5,500€ per square meter. The tax deduction will only apply to these amounts, even if the property cost exceeds them.&nbsp;The income tax reduction will be canceled if these conditions are not met.&nbsp;There is still time to take advantage of the Pinel scheme until December 31, 2024, to acquire an eco-responsible property. Afterwards, there are already alternatives such as the LMNP status (Non-Professional Furnished Landlord), combining advantageous taxation and profitability.&nbsp;

PINEL LAW - HOW A RENTAL INVESTMENT CAN REDUCE YOUR TAXES!

1. What was the trigger that led to the launch of Qarnot over ten years ago?I worked in a large French bank and noticed that the IT infrastructure needed for financial calculations generated a massive amount of heat. The servers not only produced this heat but also required constant cooling to function properly. This energy consumption was increasing every year. The idea came to me to transform this constraint into an opportunity, and reuse this heat to warm buildings and water, thus reducing the environmental impact of both computing and heating.2. Could you briefly describe your career path and introduce the duo leading the company?A former student of the Ecole Polytechnique and a telecommunications engineer, I started my career in the world of Internet startups in 2000 by participating in the creation of a web agency. In 2003, I joined the R&D department of a large bank, where I worked on one of the most significant high-performance computing infrastructures for risk analysis. It was during this time that I began to mature the concept of digital circular economy. In 2010, I met Miroslav Sviezeny, who led an electronics and mechanical engineering firm. Miroslav shared my enthusiasm, and we founded Qarnot Computing to change the data center paradigm.3. Regarding the challenge of making heating more ecological, what does the on-site valorization of the heat generated by computers consist of?Computer processors, when in operation, can reach very high temperatures, up to 70 to 90°C at full load. To manage this heat, data centers use various cooling systems such as fans, air conditioners, and sometimes liquid cooling systems. These solutions, while effective in keeping processors at an optimal temperature, also consume a lot of energy. At Qarnot, we combine an energy source for two purposes: computing and heating. We integrate computer servers directly into patented digital boilers (we started with radiators) installed in high heat-consuming sites (pools, urban heat networks, industrial sites). Instead of simply dissipating the generated heat, we reuse it for heating. This optimizes energy efficiency and eliminates the need for cooling systems.4. How do you proceed?We are primarily computer scientists, and our core business is to distribute computer calculations according to the heat requirements of each of our sites, across Europe. The computer calculations of our clients (risk analysis, 3D rendering, fluid simulations, artificial intelligence, etc.) pass through fiber and are performed in boilers that incorporate our computer servers as heat sources, to heat both a pool in Finland and a heat network in the Ile-de-France region.5. An essential resource, water. Warm water, a comfort element if there ever was one... What are the main advantages of the digital boiler?The digital boiler incorporates computer processors placed closest to aluminum plates that are in direct contact with copper pipes carrying water. It heats water up to 65°C for pools, heat networks, or industries. It valorizes 95% of the heat generated by the computer servers and reduces our cloud clients' carbon footprint by 80%.6. Staying on the water theme, how are pools heated?Our digital boilers meet the constant heat requirement (also known as the heating base load) of pools. For example, we supply (in a closed loop) a pool in the city of Kankaanpää, Finland. Our boilers produce 140MWh per year, which represents 100% of the pool's needs during the summer season and an average of 60% of annual needs.7. To what extent does this contribute to the energy transition of buildings?The digital boilers recover the heat produced by computer servers, which would otherwise be dissipated by cooling systems, making them a renewable and recovery energy source (ENR&R), benefiting from a System V Title attesting to its ecological nature.8. Regarding real estate, how do your previous achievements in professional buildings, especially radiators, differ from other contemporary green architectural projects?We believe that the best energy is, above all, the one we do not consume. Sharing an energy source for two purposes is a significant advantage!The advantage of digital radiators is that they meet a strong demand from developers, social landlords, or communities and can be installed closest to the heat requirement. However, they are subject to seasonality constraints, which is why we now only market boilers, still for professionals. Boilers, unlike other ENR&R systems, can be installed anywhere and ensure constant production without constraints related to location, climate, or deployment space.9. What will be your next challenge in digital ecology?Every day we discover new applications requiring hot water at temperatures above 55°C, whether for specific industrial processes or large heating systems. At the same time, the need for computing power continues to grow, opening up many opportunities.Furthermore, we have begun R&D to develop innovative cold production systems from the recovery of waste heat.
