Decarbonization of the real estate sector is a major focus of the Swiss 2030-2050 energy strategy. Indeed, buildings are responsible for 30% of greenhouse gas emissions and any plans to mitigate climate change needs to see these emissions reduce as soon as possible.

Founded in 2018 in Geneva, E-nno is leveraging data-driven strategies to address this challenge. E-nno developed a technology that is able to interface with any building and generate detailed data about the way it operates. In less than 12 weeks, the solution builds an understanding of the building’s behaviour and identify energy savings opportunities. Optimization algorithms are activated to automatically reduce the energy consumption of the building from 10 to 35% while guaranteeing the thermal comfort of its occupants.

Thanks to its pay-as-you-save business model, the energy savings themselves are financing the acquisition and processing of energy data in real time. It is then available for real estate professionals to take informed decisions about future energy investments together with providing accurate measurement of the environmental performance of renovation projects.

Today, the start-up deploy its technology on 20 buildings a month in Switzerland and E-nno's optimization algorithms prevented the emissions of 1,100 tons of CO2 since 2019. This is equivalent to the carbon footprint of 550 rounds trips from Geneva to New York.
