Proptech: anti-crisis solutions for energy sobriety start-ups

Posted Dec 19 2022 at 7:00 am

How to prevent the explosion of gas and electricity prices from weighing down the accounts too much? The question torments households but also companies who see their property charges get carried away without benefiting from the government tariff shield. In this context, the cohort of start-ups, born in recent years to make real estate more sober in energy and CO emissions2has a good part to play. Cozynergy is one of the pioneers.

Founded in 2013, it manages home energy renovation projects from A to Z by surfing on state aid (MaPrimeRénov’). Assessment, recommendation of work, quote, obtaining subsidies, monitoring of work… Its hybrid model combining digital platform and local agencies has proven itself. In 2021, the company recorded a turnover of 14 million euros and it plans to multiply it by ten in 2025.

Massifying energy renovation

Other platforms of the same type occupy the ground to facilitate access for individuals to energy renovation. But it is the tree that hides the forest of innovations aimed at large housing estates. A proliferation of BtoB projects that delights Agnieszka Bogucka, proptech program manager at the EuraTechnologies accelerator.

“To achieve a real ecological transition, the energy renovation approach should be consolidated and the solutions applicable to the real estate stocks managed by social landlords, co-ownership trustees, communities or large companies should be prioritized”, she insists. “I observe more start-ups that address these types of heritage. »

Geothermal energy and artificial intelligence

Thus, since its creation in 2016, Accenta, a young Ile-de-France start-up focuses on large building stocks. Its technology, which combines geothermal energy and artificial intelligence, consists of storing heat in the ground in summer with a view to using it in winter to heat buildings. The energy savings achieved can reach 85%, as at the head office of Airbus, one of its emblematic customers.

The start-up already manages 7 million square meters of buildings. Until now, its activity was driven by the so-called “tertiary” decree from the Elan law of 2018 which requires offices to reduce their consumption by 40% in 2030 and by 60% twenty years later. But the energy crisis should accelerate its forward march. Large groups that tended to push back the deadline now have their backs to the wall to reduce the impact of buildings. There remains the significant cost of renovations.

A painless financing solution

Carb0n, founded at the beginning of the year, aims to soften this brake on the energy transition. As its president and co-founder Hadrien Flon explains, the start-up takes care of the purchase of equipment, coordinates the work and sets up a rental-purchase contract. By spreading out his payment, the institutional owner absorbs the cost more easily, the energy savings obtained partly financing the renovation. In 2023, Carb0n plans to support between 15 and 30 projects for an overall budget of 30 to 50 million works. In the meantime, she is about to sign a new fundraiser after raising 1.4 million euros last September.
