ÉcoWatt sits between households, market actors, and public institutions. Understanding each stakeholder's motivations and constraints was essential to shaping what ÉcoWatt should, and should not, try to do.
These owners can make renovation decisions independently and are highly motivated by financial returns. They want clear guidance on whether renovations will actually reduce costs or improve DPE scores. ÉcoWatt supports them by providing reliable comparisons between their real consumption and what the DPE predicts.
Owners in copropriétés face collective decision-making, which often slows or blocks renovations. They need transparent data to support arguments in assemblies and justify shared investments. ÉcoWatt helps them understand potential savings and communicate these insights to their co-owners.
Renters feel the impact of high energy bills but cannot renovate their homes. They rely on everyday behaviours and subscription choices to reduce costs. ÉcoWatt serves them by highlighting habit-based savings and easy, achievable actions.
Landlords hold significant power over structural improvements and react strongly to regulations, especially rental bans for F and G properties. They care about compliance and long-term financial outcomes. ÉcoWatt offers them clear projections of ROI and future energy costs.
Agencies influence buyer and seller expectations around DPE scores. They help shape demand and pricing but often lack tools to explain discrepancies between predicted and actual consumption. ÉcoWatt can become a useful reference for them when advising clients.
As the provider of real electricity consumption data, ENEDIS is essential for accurate analysis. Their data allows ÉcoWatt to compare estimated performance with real usage, improving user trust in energy recommendations.
These actors determine how the DPE label is calculated. Their methodology shapes the expectations and constraints users operate within. ÉcoWatt complements their work by translating DPE information into practical insights for households.
Municipal, national, and EU-level regulations define the rules households must follow. These regulations, especially rental restrictions for low-rated homes, create urgency for renovation and make clarity essential. ÉcoWatt helps users understand what these rules mean in practice.
These companies enable structural improvements but depend on users being willing to invest. ÉcoWatt helps bridge this gap by explaining costs, payback time, and expected savings, making users more confident in engaging with contractors.
Energy suppliers influence how much users pay through pricing structures and subscription types. Many people find this information difficult to interpret. ÉcoWatt simplifies it by showing which changes genuinely reduce costs.
Mapping each stakeholder by how much power they hold over ÉcoWatt's impact, and how directly interested they are in its success.
The market currently offers several tools, but none provide a complete solution:
The competitors provide partial solutions: some analyse renovations, others estimate consumption, but none combine real data, habits, DPE comparisons, and clear recommendations in one place.
This makes it the first tool that shows users what they are truly paying for, why they are paying it, and which changes, small or large, will make a measurable difference.
Its prioritised features strengthen this value: the ability to upload energy bills, the comparison of real consumption with DPE predictions, the integration of renovation and behaviour-based recommendations, and the clear organisation of results into digestible sections. Together, these elements give users a transparent overview of how to save money, improve efficiency, and make sustainable renovation decisions.
Through the different milestones, ÉcoWatt has iterated and consolidated on its main values. We started the process with a problem and now we provide the solution: ÉcoWatt. On the first milestone, we studied the market and the problem. On the second, we tested our assumptions with the user, iterated, and developed a unique product. On this final milestone, we explain what ÉcoWatt means for the market and how and why it should be implemented.
Rather than a solution designed for the users, ÉcoWatt is a solution designed with the users. It continuously evolves and adapts to user needs. However, ÉcoWatt has always been consistent with its core values. When developing ÉcoWatt, we all agreed on three values that would define our project and process: clarity, transparency and accessibility.
When we first studied the market, we realised one of the problems was users' lack of information about DPE and its calculations. ÉcoWatt not only provides an overview of what DPE is and how the calculations work, but also gives users clear, actionable outputs they can adopt.
ÉcoWatt wants to create awareness of DPE discrepancies and reduce them in our model. In addition to the lack of information users had about DPE, most were unaware of the discrepancies the data possessed. ÉcoWatt is transparent with users, clearly stating the model's capabilities and limitations.
The lack of information users had was because of an accessibility issue: they didn't know where to find it, or how and why to improve their energy efficiency. ÉcoWatt aims to be that source, easy to understand and navigate for everyone.
Our values provide ÉcoWatt with a direction to follow and a vision for the reality we create. They are one of the main factors that differentiates us from our competitors.
During the ecosystem analysis, we studied different competitors in the market. That highlighted functions missing on the market, or that could be improved, which we adopted at ÉcoWatt.
When developing our user personas, we noticed two distinct groups: owners and renters. Products on the market were mainly addressed to owners, missing a business opportunity with renters. We made the product functional for both: renovations for owners who want to improve energy efficiency and increase property value, and habits and recommendations for renters who want to reduce consumption.
Even while diversifying on the market, we specialised in the data. Our model is based on Paris data provided by Enedis, and data discrepancies have been reduced to give more accurate results.
Linked to our core value of accessibility, we provide a tool that is easy to use and understand. We not only give a clear explanation of results, but also translate them into actionable insights.
Market research and user tests have proved that ÉcoWatt would create value on the existing market and differ from the competition. However, to make ÉcoWatt a reality, investors or partners are needed. Organisations such as ADEME or Enedis are examples of potential partners for ÉcoWatt's viability plan.
A question emerges: why would ADEME, Enedis, or a local authority partner with us rather than build this themselves? The answer is in ÉcoWatt's value proposition and product development.
ÉcoWatt complements rather than competes with those public institutions. Organisations like ADEME and Enedis already have the data expertise, but developing a product like ÉcoWatt requires design iteration, user research and a marketing strategy. ÉcoWatt has already been tested and has iterated to market needs. It has identified unexploited market opportunities and conducted rigorous user research. We also believe that five students created this project, a project designed by the people, for the people, to help individuals save costs. Our transparency towards such individuals, allowing us to meet face-to-face, is more effective in building trust than what the big energy companies can do.
In short, funding or partnering with ÉcoWatt would accelerate the adoption of energy-efficient behaviours, improve public understanding of DPE ratings, and maximise the impact of existing energy policies.
