Electricity prices are on the rise, and regulations, especially in Europe, are getting tougher on home energy efficiency requirements.
For example, in France, 20% of homes are not able to be rented because of their low energy efficiency rating. That’s 7 million homes in need of solutions. Homeowners like Roman, one of their first clients, needed to take action. He has a house in the Pyrenees, where his energy bill has increased by 60% in a year.
Roman never completed his home energy efficiency project. It took him months, required extensive research, involved dozens of different people, and introduced a lot of opportunities for error.
That’s what Plume is here to change for Roman and all homeowners.
On your personal account, you start by answering a few simple questions to assess your home. Then, the Plume AI software uses thermodynamic models, public housing data, energy consumption data, and satellite imagery to compute your current energy efficiency.
Next, they find the most cost-effective solutions for your specific house to increase your energy efficiency. You get an instant price, factoring in government subsidies, ROI, and installment time. All in one click.
Finally, select what fits your needs, and they will connect you with their network of selected and trained contractors and ensure the work is done.
Plume helps you at every step of that journey, making the process seamless, trustworthy, and 10 times faster.

With energy prices going up, homeowners are now pressured by their energy bills and regulations to care about building efficiency. The good news is that homes are electrifying enabling new tools to improve their home energy efficiency.
Looking only at France: 20% of houses are not able to be rented because of their low energy efficiency rating. That’s 7 million homes requiring an average home energy renovation of $20k. This represents $140B in renovation that will be done in the next three years.
