Interclima · 2026

Agoris analysis · updated May 2026

Key takeaways

• Interclima 2026 runs concurrently with Batimat and Idéobain at the Mondial du Bâtiment (renamed "Mondial du Bâtiment") from 28 September to 1 October 2026 → exhibiting at Interclima does not carry the same commercial scope as exhibiting at Batimat: it is a specialised sub-segment for HVAC engineering, not the entire construction sector.
• 42,525 visitors at the 2024 edition, almost identical to 2022 (42,506) (source: uniclima.fr) → stable footfall across 2 biennial cycles, despite a context of rapidly accelerating energy transition.
• 205 exhibitors registered in 2024, of which 82 were new (source: uniclima.fr). A strong international component sets Interclima apart from Batimat and reflects the European industrial dimension of HVAC engineering.
• Trade show owned by Uniclima (professional trade body) and organised by RX France → Uniclima sets the strategic direction (energy transition, low carbon), RX handles the production.
• 4 business universes structure the offering (heating, summer comfort, ventilation and IAQ, hydraulic fluids) → an exhibitor targeting only one universe can confine their investment to a single village of the show.

Who exhibits

Typical profile

HVAC engineering manufacturers: makers of boilers, heat pumps, ventilation and indoor air quality systems, refrigerants, network hydraulics. Strong presence of European manufacturers (50% international exhibitors announced for 2026, source: interclima.com).

Quality of the visitor base

As Interclima is co-located with Batimat, the shared visitor base is largely that of the Mondial du Bâtiment, which recorded 85% French visitors, including 45% from the Île-de-France region, at the 2024 Batimat edition.

Activities & community

Conference programme

The 2026 programme is built around 3 announced themes: decarbonisation, indoor air quality, energy performance of tertiary buildings (source: interclima.com). For 2024, the Mondial du Bâtiment as a whole counted around 450 conferences.

Awards & accolades

"Innovation Awards Interclima": a product innovation competition with 54 participating companies in 2024 and 6 winners selected. A category created in 2024: "Tertiary HVAC engineering" (source: uniclima.fr).

Satellite events

A start-up space dedicated to HVAC engineering with Innovation Awards pitches. Thematic villages announced for 2026: Biomass Boilers, Solar Thermal, Tertiary Solutions (source: interclima.com).

Community & networks

Trade show owner: Uniclima. Institutional partnerships with the heating and ventilation federations (SYNASAV, Flamme Verte). Specialist press: Le Génie Climatique, Chauffage Bois Magazine.

On site: what you need to know

Access, parking and accommodation: see the listing for Paris Expo Porte de Versailles.

Specific to the trade show:

• Pavilion location: Hall 7.3 of the Parc Expo Porte de Versailles.
• Opening hours: 9 a.m.-7 p.m. on the first 3 days, 9 a.m.-6 p.m. on Thursday 1 October (source: interclima.com/infos-pratiques).
• Visitor badge: 2026 prices not yet published (2024 price known: €30 excl. VAT early-bird / €60 excl. VAT after 20 September). Free badge with an exhibitor invitation code. The badge grants access to the 3 trade shows of the Mondial du Bâtiment (Batimat + Interclima + Idéobain) (source: interclima.com/faq).

How much it costs to exhibit

Exhibitor prices not published: quote on request from RX France via the exhibitors page on interclima.com. As Interclima is co-located with Batimat and organised by the same RX France, the per-m² ranges are presumably close to those of Batimat (€250-400/m² for a bare stand at Batimat 2026, source: cimbat.com), to be confirmed by a direct Interclima quote.

Preparing your visit

For the exhibitor

• 18 months out: make contact with RX France, request a quote, apply for the Innovation Awards.
• 12 months out: validate the stand concept, select the targeted business universe(s), brief the contractor.
• 6 months out: finalise the stand plan, place the construction order, materials logistics.
• 3 months out: team accreditations, accommodation (book early, Mondial du Bâtiment draws crowds).
• 6 weeks out: deliver materials, final brief, activate the Mondial du Bâtiment app.

For the decision-making visitor

• Request a free invitation code from an Interclima or Batimat exhibitor rather than paying the standard badge price.
• Allow at least 1 day for Interclima alone, 2 days if the visit also covers Batimat.
• The badge grants access to the 3 trade shows of the Mondial du Bâtiment: plan your route accordingly.

Policy & CSR initiatives

Interclima's CSR dimension is structural: the trade show is steered by Uniclima around the energy and low-carbon transitions, and its 2026 programme puts decarbonisation and indoor air quality front and centre (source: interclima.com). The "Tertiary HVAC engineering" category of the Innovation Awards rewards energy performance solutions.

How the trade show has evolved

Trajectory analysis

Visitor footfall stable across 2 biennial cycles (42,506 → 42,525 between 2022 and 2024), in a sector context that is nonetheless rapidly accelerating (RE 2020, the end of gas boilers). This stability may reflect either a structural ceiling for the trade show or a calendar-saturation effect (visitors prioritising Batimat within the Mondial du Bâtiment scope). One to watch for 2026: the impact of the "Mondial du Bâtiment" rebranding on Interclima-specific attendance.
