This annual report highlights the contributions of the Laboratory of Integrated Comfort Engineering (ICE) at EPFL to IEA EBC Annex 87 in 2025. Prof. Khovalyg and the ICE lab team have been deeply engaged in advancing research on Personalized Environmental Control Systems (PECS) through scientific editorial work, extensive literature reviews, and multiple collaborative initiatives within Annex 87. Their contributions span leading and co-authoring major systematic reviews, participating in ongoing reviews on PECS control, integration, and environmental requirements, and supporting international research efforts on thermal sensation modelling, manikin-based performance evaluation, and low-energy functional criteria for PECS. In parallel, the team is developing methodological frameworks for assessing PECS energy and comfort performance and is conducting an SNSF-funded project on energy-efficient personalized comfort systems. This includes defining testing conditions, planning and implementing manikin experiments, and launching laboratory measurements to quantify local effects and energy use of representative PECS devices. Prof. Khovalyg also disseminated Annex 87 activities by leading workshops at COBEE 2025 and CISBAT 2025, fostering discussions on user experience, evaluation methods, and the broader adoptability of PECS solutions
