The call for papers for the InnoEE-2024 Conference is open until 15 April! Accepted papers will be published in the open access IOP Conference Series: Earth and Environmental Science and will be indexed...
Welcome to InnoEE-2024!
Dear colleagues,
The 29th annual edition of the Conference of the Faculty of Power Engineering and Power Machines (FPEPM) is conducted under the name of Innovations in Energy and the Environment (InnoEE), and will be held on 14-15 May 2024. The conference is part of the Days of Science activities at the Technical University of Sofia and is conducted in strategic partnership with the European Technology and Innovation Platform on Renewable Heating and Cooling. The major theme of this year’s conference is:
Sustainable and Affordable Energy, Environmental Comfort, and Protection of the Natural Environment
InnoEE-2024 will be a platform for sharing recent innovations, advancements and developments in the fields of energy engineering, fluids and thermofluids engineering, building services engineering, refrigeration engineering, textile engineering, and other disciplines, pertinent to the thematic sections of the conference:
The conference has established itself as a prominent scientific forum with long-lasting tradition, gathering Bulgarian and foreign experts from academia, industry and the government. It will be an excellent opportunity to present and publish your recent work, to connect with other professionals, and to make a contribution in these important fields of knowledge. Accepted papers will be published in the open access IOP Conference Series: Earth and Environmental Science and will be indexed in major worldwide databases (e.g. Scopus and WoS). The full list of databases is available here.
We invite industry partners and professional societies to support our efforts, so that together we can produce a first-rate conference with engaging presentations, exciting activities and fun events.

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”.

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.
