Renergia, the app that makes energy consumption more efficient and reduces bills, launched internationally during COP28

Energy Advisor, the first start-up affiliated with the Technical University of Cluj-Napoca, launches Renergia, the mobile application that streamlines energy consumption and reduces energy bill costs.

Renergia analyses household energy consumption and generates an estimate of monthly and annual associated costs, as well as provides data on the potential savings in electricity and thermal energy. The analysis conducted by Renergia is based on an innovative algorithm that combines concepts of statistics and probability with advanced algorithms, assisted by artificial intelligence.

The proprietary algorithm of Renergia is trained to detect outliers and make precise predictions of energy consumption using a set of basic information. This innovative tool estimates both electrical and thermal energy consumption while simultaneously generating personalized energy efficiency plans for users.

As a result, the use of the Renergia application can potentially reduce monthly energy (electricity and thermal) bills by up to 30% when the recommended energy efficiency measures are implemented. The reduction in bills also depends on the configuration of household equipment and, especially, the level of thermal insulation of the residence.

Renergia can also be used to provide a comprehensive analysis of the carbon footprint in the residential sector. Currently, the carbon footprint of a household in Romania exceeds 2,200 kg of CO2 per year when considering final energy consumption (electricity and thermal).

“The approach proposed by Renergia is innovative and unique. There is currently no similar approach in Romania or across Europe. In developing the application, we started with the idea that what we cannot measure, we cannot improve. Hence, the very important component of determining the carbon footprint, in addition to improving energy consumption efficiency and reducing bill costs”, says Dr. Ing. Alexandru Mureșan (photo left), CEO of Renergia, emphasizing that energy waste is significant in Romania, and the implementation of energy efficiency measures and the use of renewable sources should be encouraged because, on the one hand, they will increase our resilience, by reducing dependence on centralized sources, and on the other hand, they will increase the comfort level of

“The tool for estimating the sizing of photovoltaic systems is dedicated exclusively to households, but the concept also involves B2B partnerships. We have a framework contract signed with an authorized installer of photovoltaic systems that offers consultancy to Renergia users and turnkey installation services. Additionally, we are discussing, on several levels, with financial institutions that can offer green credits to end users, for the installation of such technologies”, says Dr. Ing. Dacian Jurj (photo right), COO Renergia.

Renergia was developed by a team of 12 specialists with expertise in energy, advanced numerical methods, software, marketing and strategy. To date, the investment in the development of the application has been over 300,000 euros. The starting point of the project idea was June 2022, and the actual implementation of the project began in January 2023.
