PROJECT BRIEF

From Industry 5.0 to Education 5.0: Humanising technology

17:30 – 19:00

EXHIBITION OFFICIAL OPENING

Eco-aeSTHETICS 2.0: Humanising technology

Curator: Ivaylo Peev, Technical University of Sofia

The exhibition presents wood sculptures and engineering projects – kinematic sculptures, associating with topics related to the concepts of energy, aesthetics and ecology. This year the authors also add the concept of technologies, their place in the life of modern men and an attempt to humanize them. The ecological element could be seen again in the material – WOOD and its aestheticization is evident in the highly artistic interpretations and techniques used by the professional woodcarvers from “Group 9”.

Ivan Dimchev, PhD

Lecturer

Senior Assistant Professor • Technical University of Sofia

WORKSHOP

Determining the Seasonal Coefficient of Performance (SCOP) of air-to-water heat pumps according to EN 14825: Calculations based on local climate data

The purpose of this workshop is to demonstrate the procedure for adaptation of the data used for determining the Seasonal Coefficient of Performance (SCOP)—as provided by heat pump manufacturers—to the local climate conditions. The workshop highlights the specifics of the current national regulations transposing the EU’s Energy Performance of Buildings Directive. The lecturer will present a detailed example, based on the heating demand and local climate data for a specific building, as well as coefficient of performance data for the given water outlet temperature provided by the heat pump manufacturer.

Free admittance after registration (below). The number of seats is limited to 30.

Location & Venue

The InnoEE-2024 Conference will be held at the newly renovated Building 8 of the Technical University of Sofia. The main room, where the conference sessions will take place, is the hall named after Prof. Tsvetan Lazarov, a renowned Bulgarian scientist and aviation engineer. 

The building also houses multiple brand-new laboratories of the National Center for Mechatronics and Clean Technologies. A complimentary tour of the laboratories could be provided to participants (upon request). 

Registration, exhibitions and social events will take place at the lower floor of the building. On both days lunch will be served for all participants in an area with access to the back courtyard. The farewell cocktail will also take place there. 

A dinner reception will be organised on the evening of the first conference day. The dinner reception will be held in the Stara Sofia Restaurant at Vega Hotel Sofia, located at less than 15-minute walking distance from the conference venue.
