What Climatherm Energy does
Climatherm Energy is a biennial international trade exhibition focused on the energy, heating, cooling, and renewable energy sectors, organized by Project Ltd (PROJECT ΕΠΕ), a private Greek company headquartered in Néa Smírni, Greece. Founded in 1991, the exhibition has operated continuously for over 35 years as the only specialized international energy exhibition in Greece, held at the Athens Metropolitan Expo — the country's sole international-standard exhibition center. The event operates under the official auspices of the Greek Ministry of Environment and Energy and serves both energy-sector companies (exhibitors) and professional visitors including engineers, architects, plumbers, electricians, hoteliers, construction firms, and refrigeration technicians from Greece and abroad. Attendance has ranged from 18,500 to 25,000 trade visitors per edition across 2014-2022.
The exhibition's core product is the physical biennial trade show itself, complemented by two digital infrastructure assets: the edo.events B2B matchmaking platform for scheduling exhibitor-visitor meetings before, during, and after each event, and a 360° virtual tour of the exhibition venue. The 2026 edition (scheduled February 27 – March 1) is expanding into structured educational programming through partnerships with NTUA's Applied Thermodynamics Laboratory, GSEVEE's Technical and Vocational Training Center, and the Hellenic Refrigeration Federation, covering topics such as EC Regulation 573/2024 refrigeration technician certification and A2L refrigerant safety. There is no proprietary technology stack; the company's intellectual property centers on brand recognition, institutional relationships, and event production know-how.
Climatherm Energy monetizes through three primary revenue streams: exhibition booth rental (the dominant stream, with multiple booth types and sizes available), corporate sponsorship at tiered levels with logo placement and promotional materials, and on-site advertising opportunities within the exhibition space. Specific pricing is not publicly disclosed; prospective exhibitors must contact the organizer directly. The customer base is horizontally diversified across energy-sector sub-verticals — solar, geothermal, natural gas, HVAC, photovoltaics, water treatment, desalination, and building energy upgrades — reducing concentration in any single technology segment. Operating geographies span Greece as the primary market, with documented exhibitor participation extending to Cyprus and broader Southeast Europe.

Climatherm Energy competitors and assessment
Company assessmentDirect peers
- Intersolar Europe: Intersolar Europe is the continent's leading solar industry exhibition held alongside The smarter E Europe. Climatherm covers solar/photovoltaic technologies among its product categories, directly overlapping with Intersolar's exhibitor and visitor base.
- ISH Frankfurt (Messe Frankfurt): ISH is the world's leading trade fair for HVAC, water, and energy, organized by Messe Frankfurt. Climatherm Energy operates as a similar specialty exhibition serving the same HVAC/energy professional audience, just on a smaller regional scale focused on Greece and Southeast Europe.
- MCE Milan (Mostra Convegno Expocomfort): MCE Milan is a major biennial HVAC, plumbing, and renewable energy exhibition held in Milan. Like Climatherm, it targets installers, engineers, and architects with product showcases and seminars, making it a directly comparable European energy trade show.
Broad incumbents
- The Big 5 (Dubai): The Big 5 is the largest construction industry exhibition in the Middle East, with HVAC and MEP segments overlapping Climatherm's focus. It serves a much broader portfolio than Climatherm but competes for the same category of HVAC/energy exhibitors in adjacent geographies.
- BATIMAT Paris: BATIMAT is a major French/European building and HVAC construction trade show. It overlaps with Climatherm's building technology, heating, and ventilation categories but operates at a much larger scale and broader scope.
- Messe Düsseldorf (Energy Storage / Heat & Power): Messe Düsseldorf organizes multiple trade fairs including energy and HVAC-related events. As one of Europe's largest exhibition organizers, it competes for the same European HVAC/energy exhibitor pool as Climatherm through its portfolio events.
Regional players
- TIF HELEXPO (Thessaloniki International Fair): HELEXPO operates the Thessaloniki International Fair and other Greek exhibitions. It is a regional peer in the same Greek exhibition-organizing industry, though not a direct competitor to Climatherm's energy specialization.
- Aqua-Therm Moscow: Aqua-Therm Moscow is a regional HVAC and plumbing exhibition serving the Russian/CIS market. It is comparable to Climatherm in product categories (heating, cooling, water) and target audience of HVAC installers and engineers, but operates in a different geography.
Emerging players
- FORUMEC (Forum on Energy and Climate): An energy-focused industry event/conference targeting HVAC and sustainability professionals. Climatherm overlaps in its target audience of energy professionals and its positioning around sustainability and energy efficiency topics.
- Refrigeration Industry Association trade events: Industry-association-led refrigeration conferences and exhibitions (e.g., organized by IOR or the Hellenic Federation of Refrigeration, a Climatherm partner). These compete for the refrigeration technician audience that Climatherm actively serves through its seminars and workshops.
