Machine Learning Prediction of Student Satisfaction on Indoor Air Quality and Thermal Environment in a Norwegian Secondary School

Alam, Azimil Gani; Mathisen, Hans Martin; Cao, Guangyu; Bartonova, Alena; Høiskar, Britt Ann Kåstad; Fredriksen, Mirjam

Ensuring a healthy and comfortable indoor environment in schools is essential for student well-being and academic performance. The purpose of this study is to investigate the factors influencing students’ satisfaction with indoor air quality (IAQ) and thermal comfort in classrooms. To address this, one year-long measurements were conducted across multiple classrooms in a Norwegian secondary school, collecting data on indoor climate (CO₂, VOC levels, temperature, relative humidity, and air pressure) along with outdoor climate variables (temperature, humidity, and solar radiation). Additional room-specific data, including orientation, floor level, and ventilation system specifications, were also considered. An online feedback system was used to gather 1,473 real-time student responses on satisfaction levels. Supervised machine learning (ML) models were developed to assess the importance of these parameters in predicting perceived indoor comfort: IAQ perceptions and thermal environmental perceptions. Results showed ML models effectively predicted student dissatisfaction, achieving accuracy greater than 80% when environmental and building parameters were considered simultaneously. The findings emphasized that dissatisfaction with indoor conditions is driven by multiple interacting factors of measured variables and building parameters single independent variables. SHAP analysis provided valuable interpretability, revealing how variations in environmental conditions collectively impact students' perceived comfort. This comprehensive approach demonstrates the practical potential of ML-based IEQ monitoring systems, suggesting that schools can proactively improve indoor conditions through targeted interventions informed by real-time predictions.

The NextGEOSS Cold Region pilot: Improved discoverability and access to polar data

Hamre, Torill; Bye, Bente Lilja; Fiebig, Markus

GEO Cold Regions coordinates global efforts to provide Earth Observation (EO) products and services to science, decision- and policy-makers with a vested interest in the cryosphere (in particular) and the environment (in general) of polar regions and mountain areas around the world. The NextGEOSS Cold Regions Pilot focuses on three areas: (1) the Arctic/Svalbard region, (2) Antarctica, and (3) the Himalayan glaciers, linking together satellite and in situ data from the targeted regions, including the atmospheric, marine, and terrestrial domains, and making them available in the NextGEOSS Data Hub and the NextGEOSS Cold Regions Community Portal. The pilot liaise with ongoing initiatives such as SIOS, GEOCRI, WMO GCW, as well as national programs in Antarctica. The products resulting from the Cold Regions pilot can be used to develop Information Services for the Cold Regions Initiative, using the NextGEOSS system and making use of existing interoperability standards. This presentation will introduce the first version of the Cold Regions Community Portal, aiming to make polar data relevant for Cold Regions more easily discoverable and accessible for users.

ICOS Norway – a carbon cycle infrastructure

Lauvset, Siv Kari; Myhre, Cathrine Lund; Lange, Holger; Olsen, Are; Stohl, Andreas

The Integrated Carbon Observation System (ICOS) research infrastructure is aimed at quantifying and understanding the greenhouse gas balance of Europe and neighboring regions. ICOS-Norway brings together the leading
Norwegian institutes for greenhouse gas observations in the three Earth system domains atmosphere, ocean, and
terrestrial ecosystems, providing world-leading competence, which is integrated into one jointly funded and operated infrastructure. This provides Norway with a state-of-the-art research infrastructure embedded in European
and global efforts. Even though each Earth system domain was part of dedicated research infrastructures prior to
the establishment of ICOS-Norway, the greenhouse gas community in Norway was divided and there was minimal
collaboration across the Earth system domains. The overall goal of ICOS-Norway is to provide accurate and accessible data on, as well as integrated assessments of, the Norwegian carbon balance at regional scale, across the land,
ocean, and atmosphere. ICOS-Norway has thus led to an increased impact of environmental observing systems
in Norway and surrounding seas, easily seen through the number of publications and new proposals generated
as collaborative efforts. This poster presents the ICOS-Norway infrastructure, including plans for expansion and
long-term funding.
