This is the 29 th annual edition of the event, part of the “ Days of Science ” activities at the Technical University of Sofia . For the past 29 years, this conference has become a traditional annual scientific forum for the meeting of Bulgarian and foreign experts and industry representatives in the field of energy and renewable energy technologies, thermodynamics, heat engineering, building efficiency improvements and HVAC systems, environmental engineering and protection, hydraulics and pneumatics, textile and sewing production. All received publications are peer reviewed and traditionally, the highest quality scientific papers are further submitted for publishing in referenced partnering journals. Based on recent years of experience, the conference offers on-site and online possibility for attendance. The program includes keynote lectures from selected popular topics in the presented areas, as well as oral presentations of the papers by the participants. It became a tradition, for some of the main sponsors, to organize special demonstration stalls in the conference area, where they can expose their latest innovative products and have a closer meeting with the audience. This year, three exhibitions were organized and performed as side events, during the conference days. The first one is continuation of the last year event, called “ Eco-aeSTHETICS 2.0: Humanizing technology ”, and it is an exposition of nine woodcrafter sculpture artists, developing the “energy concept” in their work. The second exposition presented students’ design ideas for devices or technologies for green and sustainable energy utilization. The last exhibition was devoted to the technical and industrial sponsors of the InnoEE 2024 conference. It included a demonstration of the recent products of the Hexonic company and Tapflo , mainly heat exchangers and special industrial pumps. Also, main attraction of this exhibition were the several demonstration cars with hybrid and electric drive, delivered by Toyota . The participants of this year event had the opportunity to get closer look of these newest Toyota models and even to have a test drive, during the conference days.
