The solution

To carry out a technical diagnosis of the heating system to optimize the installations (life and, environmental and economic impact) in collaboration with the heater in place.

To do this, it is possible to use a digital performance diagnostic application of a heating system.

    Who is it for?

    • I am a resident/condominium,who wants to save energy to lighten my bill and my carbon footprint.
    • I am a CSR company/service,and I want to make my building more efficient in order to lighten my bill and my carbon footprint.

    Ingredients

    • A boiler room to optimize (70 to 6000kW of power)
    • The collaboration of your heating technician
    • Support for your condominium
    • Steps to implement this solution
    • Information about the digital app
    • Information on energy sobriety

    Preparation

    Step 1: Having motivated co-owners

    Having motivated co-owners to reduce:

    • Their energy consumption;
    • Their environmental impact.

    Present the benefits for everyone at the next condominium meeting.

    Step 2: Contact a company that specializes in optimizing collective heating
    Step 3: Establishing a dialogue at a collaborative meeting

    Establish a dialogue at a collaborative meeting with all the players of this building (union of co-owners, manager, heater, expert of the company).

    At this meeting, everyone’s objectives and roadmap can be established.

    Step 4: Make a diagnosis of the current facility

    Make a diagnosis of the current facility:

    • Performance of the installation ranging from fuel supply to individual heating sources;
    • Financial and environmental assessment.

    The goal is to:

    • Putting in place a short-term and medium-term action plan;
    • Model financial and environmental impacts.

    Step 5: Facilities upgrades and upgrades

    The company assists the operator on the adjustments and work to be done to improve yields. At the same time, the operator and heater are technically trained on environmental measures.

      Step 6: Setting up new settings
      Step 7: Occupants' awareness of energy sobriety

      To do this, we have three files available to you:

      1. A very short, simple and visual infographic (by Save The Alps)
      2. A much more complete and technical file (by Negawatt);
      3. The environmental impact of biogas (by ADEME)

      Maintenance
      • Monitoring energy consumption and environmental impact to have concrete figures and to be able to improve continuously.

      Benefits

      Details of the figures can be found in our “sources” section below

      Up to 35% energy savings

      • Immediate return on investment time;
      • Reducing the bill of all residents;
      • Even new or un insulated buildings (e.g. listed building or city building) can save money.

      Reducing CO2 emissions by 13.5 tonnes per year

      • Better thermal efficiency;
      • Decreased energy consumption;
      • Conversion of old oil boilers to biomethane or biopropane;
      • Increased hardware life.

      Towards sobriety

      • Raising awareness of energy sobriety;
      • Accessible even to condominiums in great energy insecurity;
      • Transparency and dialogue;
      • Professionalization of the heater.

      Precautions of employment

      • Be aware that a collective building of 25 dwellings pollutes as much as 35 cars that travel 12,500km each year!
      • Just because you have the best boiler doesn’t mean you get better
      • Act collaboratively with all actors and have an upward vision
      • Keep in mind that in the building, the human and the technical are at the heart of the energy transition.

      Creator of the solution

      “Our mission is to tackle the waste generated by the inefficiency of collective boilers. Based on more than 26 years of experience as a heating operator and building design/control office, we have developed a new approach to boiler room performance diagnostics. Through this, we put the human being back at the heart of the energy transition by creating the unique dialogue between the different players in the building.

      We are driven by the desire to really act for the environment by improving the efficiency and lifespan of heating installations, while reducing energy expenditure. »
