At the II International Technology Festival "Energotechnofest-2025", which brought together 4,000 innovators from 32 countries, graduate student of the St. Petersburg State Institute of Technology (SPbGTI) Sergey Lebedev presented a breakthrough development for intelligent control of large-format electrochromic glass. The project was implemented with the support of Octoglass, a world leader in the production of electrochromic solutions. The system was included in the top 10 finalists of the Energotechnohub Incubator, who fought for a grant of 1 million rubles.

Key aspects of development

1. Smart energy management. The system allows you to dynamically adjust the transparency and tinting of glass in buildings, reducing air conditioning costs by up to 40%.
2. Integration with Octoglass products. The solution is compatible with the company's electrochromic panels, providing centralized control through the United Lab platform. This eliminates manual settings and synchronizes the operation of devices from different manufacturers.
3. Industrial application. The technology has been tested at the facilities of Gazprom Neft— a strategic partner of the festival. Alexander Dyukov, the head of the company, noted its potential for the tasks of the fuel and energy complex and "smart" cities.

Energotechnofest 2025 has become the largest platform for young engineers: the number of participants has increased 4-fold since 2024. Alexander Beglov, the Governor of St. Petersburg, emphasized the festival's role in implementing the President's instructions on technological development. Over the past 5 years, 1,500 startups have received support, creating 5,000 innovative solutions.

About the developer:

Sergey Lebedev is the winner of the Student of the Year 2021 contest in the scientific and technical creativity category. His research on electrochromic materials began at SPbGTI(TU) under the leadership of:

• Candidate of Technical Sciences Evgeniya Sokhovich (Chemistry of nanomaterials)
• Ph.D. Valeria Borodzyuli (Physics of automated systems);
• Doctor of Technical Sciences Leon Rusinov (industrial automation).

Over the past year, Sergey's team has patented 4 inventions, won grants from the Skolkovo Foundation and the Russian Science Foundation, and the United Lab project has entered the top 100 technology startups in Russia.

"Cooperation with Octoglass has opened access to industrial tests. Their expertise in scaling solutions helped to adapt the system for skyscrapers," Sergey said in an interview.
