Hosted by CAE — Advanced Thermal Management group (Jochen Manara)
Format Two days: 21 invited talks (25-minute slots, 20 min + 5 min discussion; two 50-minute plenaries), laboratory tour, two poster sessions, round table and Young Speaker Award
Attendance About 40 participants from metrology institutes, research centres, universities and industry in Europe and the United States

The second IR-EMPOWER moves the series from Bilbao to Würzburg, keeping what made the first edition work: a single topic — how infrared emissivity is measured, compared, modelled and used — and a room small enough for every talk to become a discussion. The programme runs from the national metrology institutes (PTB, LNE) and high-temperature facilities (CEMHTI, JRC, CAE) to additive manufacturing, construction materials, spacecraft coatings, and open data. The two plenaries come from the series’ founding group at UPV/EHU and from LTeN-CNRS, coordinator of the French research network TAMARYS.

From the Bilbao group

The Thermomat / HAIRL group at UPV/EHU, which founded the series, contributes two talks and three posters:

Round table

The workshop closes on Tuesday afternoon with a round table on how the community should develop. The agenda set by the organisers covers four themes:

  1. Young Speaker Award
  2. Developing the community — the emissivity.org website, mailing lists and newsletter, visibility, intercomparisons and round-robin tests, data collection
  3. Collaborations — networking, funding (e.g. COST Actions, Horizon Europe), thematic working groups, links with groups worldwide
  4. The future of IR-EMPOWER — periodicity, format, venue

The outcomes will be summarised here after the workshop.

Young Speaker Award

As in 2024, the Young Speaker Award recognises the best talk by a doctoral researcher. The winner will be announced at the round table on 29 September and listed here.

Citing a talk

BibTeX entries for all 21 talks: ir-empower-2026.bib. Where a speaker deposits slides or an abstract with a DOI, the entry will point to it.

The series

IR-EMPOWER 2026 is the second edition. The first, IR-EMPOWER 2024, was held at Bizkaia Aretoa in Bilbao on 5–6 September 2024. See all editions.
