To understand how transition across different thermal zones in a building impacts the thermal perception of occupants, the current work examines occupant feedback in two work environments — nursing staff in hospital wards and the workers in an office. Both studies used a mix of subjective surveys and objective measurements. A total of 96 responses were collected from the hospital wards while 142 were collected from the office. The thermal environment in the hospital wards was perceived as slightly warm on the ASHRAE thermal sensation scale (mean TSV = 1.2), while the office workers rated their environment on the cool side (mean TSV = 0.15). The results also show that when the transitions were across temperature differences within 2 °C, the thermal perception was not impacted by the magnitude of the temperature difference — as reflected in occupant thermal sensation and thermal comfort/thermal acceptability vote. This would imply that the effect of temperature steps on thermal perception, if any, within these boundaries, was extremely short lived. These findings go towards establishing the feasibility of heterogeneous indoor thermal environments and thermal zoning of workspaces for human comfort.

Light therapy for older persons with dementia is often administered with light boxes, even though indoor ambient light may more comfortably support the diverse lighting needs of this population. Our objective is to investigate the influence of indoor daylight and lighting on the health of older adults with dementia living in long-term care facilities. A systematic literature search was performed within PubMed, CINAHL, PsycINFO, Web of Science and Scopus databases. The included articles (n=37) were published from 1991 to 2020. These articles researched the influence of existing and changed indoor light conditions on health and resulted in seven categories of health outcomes. Although no conclusive evidence was found to support the ability of indoor light to decrease challenging behaviors or improve circadian rhythms, findings of two studies indicate that exposure to (very) cool light of moderate intensity diminished agitation. Promising effects of indoor light were to reduce depressive symptoms and facilitate spatial orientation. Furthermore, there were indications that indoor light improved one’s quality of life. Despite interventions with dynamic lighting having yielded little evidence of its efficacy, its potential has been insufficiently researched among this study population. This review provides a clear and comprehensive description of the impact of diverse indoor light conditions on the health of older adults with dementia living in long-term care facilities. Variation was seen in terms of research methods, (the description of) light conditions, and participants’ characteristics (types and severity of dementia), thus confounding the reliability of the findings. The authors recommend further research to corroborate the beneficial effects of indoor light on depression and to clarify its role in supporting everyday activities of this population. An implication for practice in long-term care facilities is raising the awareness of the increased lighting needs of aged residents. Original article at: https://doi.org/10.2147/CIA.S297865

The Utrecht SBE16 Conference. From the introduction: "The conference is part of the Sustainable Built conference series and is as such considered to be part of the pre-eminent international conference series on sustainable building and construction endorsed by iiSBE, UNEP-SBO and FIDIC. The Utrecht SBE16 conference is hosted by the Centre of Expertise Smart Sustainable Cities of HU University of Applied Sciences Utrecht, in partnership with six Dutch Universities of Applied Sciences (Avans, Saxion, Rotterdam, The Hague, Zuyd, InHolland) and the Utrecht Sustainability Institute (USI). The Transition Zero conference provides us with a unique opportunity to meet transition professionals in urban sustainability from all over Europe and beyond and to learn about the latest developments and best (inter)national practices in urban sustainability. The rich interest in the conference, made it possible to offer research as well as practitioner-driven tracks on topics related to the conference title. The conference brought together excellent future-minded practitioners, researchers and thought leaders from the R&I community, specialists and professionals on zero energy homes and transition of the built environment."

In recent years, organizations across Europe, and the Netherlands in particular, have increasingly supported efforts to enhance the sustainability of festivals such as the European Climate Pact, launched by the European Commission as part of the European Green Deal, European Festivals Association and Green Deals Circular Festivals in the Netherlands (European Union [EU], 2025). As a result, festivals across Europe are growing their environmental stewardship and serving as prototypes for wider societal transitions towards sustainability (Calvano, 2024; Irimiás et; al., 2024). However, festival organizers and other stakeholders still face challenges in developing effective communication strategies that truly activate more sustainable behaviour among festival goers (Harms et. al., 2023). Generic, one-size-fits-all approaches are often applied, yet they tend to have limited impact. This is also due to the diverse nature of music festivals, ranging from indoor to outdoor settings, single-day events to multi-day experiences, and from urban to rural locations, all of which shape the audience, context, and communication needs in unique ways (Tölkes & Butzmann, 2018; Dodds et. al., 2020). Essentially, festivals are ideal for informing, experiencing and activating sustainable behavioural change through effective communication before, during and after festivals. It is therefore crucial that a more targeted approach is utilized where messages can be tailored to make communication more effective (Temmerman & Veeckman, 2024). To address pressing sustainable and social challenges within the festival sector, NHL Stenden (NHLS) will collaborate with ESNS and Thansk on a design research project. In partnership with a network of festival organizers, industry professionals, and experts, the project will explore effective communication strategies for sustainability. The goal is to develop an actionable, research-informed roadmap that supports music festivals in enhancing their sustainability communication tailored to the sector’s dynamic and diverse nature.
