In 2004 the first adaptive thermal comfort guideline was introduced in the Netherlands. Recently a new, upgraded version of this ISSO 74 (ATG) guideline has been developed. The new requirements are hybrid in nature as the 2014 version of the guideline combines elements of traditional non-adaptive comfort standards with elements of adaptive standards. This paper describes the new guideline and explains the rationale behind it. Also changes in comparison with the original 2004 version and issues related to performance verification are discussed. The information presented in this paper can be used by others (other countries) as inspiration material for other new adaptive comfort guidelines and standards.

Many cities are facing challenges in finding an equilibrium in the use of urban consumption spaces. Urban consumption spaces comprise different sociospatial relationships, bringing together work, consumption, recreation and habitation in a delimited area within the city. This mixed character is a potential source of creative urban quality, but this quality is not always realized, leading to on the one hand 'overheating' in some urban consumption spaces faced with excessive, imbalanced usage, and on the other ‘undercooling’, with declining visitors and vacant lots. We focus on Amsterdam as our living lab, in our aim to develop a new perspective toward reinstating the sociospatial relationships between local community stakeholders and to restore the equilibrium of Amsterdam city center as an urban consumption space. In doing so, we address the research question How do residents, entrepreneurs and visitors perceive ‘hospitality’ in their lived-in experience of Amsterdam as urban consumption space, and how does this contribute to community connectedness?

As people age, physiological changes affect their thermal perception, sensitivity and regulation. The ability to respond effectively to temperature fluctuations is compromised with physiological ageing, upsetting the homeostatic balance of health in some. As a result, older people can become vulnerable at extremes of thermal conditions in their environment. With population ageing worldwide, it is an imperative that there is a better understanding of older people’s thermal needs and preferences so that their comfort and wellbeing in their living environment can be optimised and healthy ageing achieved. However, the complex changes affecting the physiological layers of the individual during the ageing process, although largely inevitable, cannot be considered linear. They can happen in different stages, speeds and intensities throughout the ageing process, resulting in an older population with a great level of heterogeneity and risk. Therefore, predicting older people’s thermal requirements in an accurate way requires an in-depth investigation of their individual intrinsic differences. This paper discusses an exploratory study that collected data from 71 participants, aged 65 or above, from 57 households in South Australia, over a period of 9 months in 2019. The paper includes a preliminary evaluation of the effects of individual intrinsic characteristics such as sex, body composition, frailty and other factors, on thermal comfort. It is expected that understanding older people’s thermal comfort from the lens of these diversity-causing parameters could lead to the development of individualised thermal comfort models that fully capture the heterogeneity observed and respond directly to older people’s needs in an effective way.

The thermal performance of conventional flat roof systems is in practice normally assessed by the heat transfer caused by conduction. The effects of radiation and convection are in such cases ignored as being insignificant. Holistic flat roof systems are designed to better utilize the impact of radiation and convection on improving the indoor climate. However, to determine the influence of radiation and convection, an integrated assessment should be used. In this article, the effect of applying five different holistic flat roof systems is compared with a conventional roof system of an existing storage hall. With EnergyPlus the internal air temperature in the storage hall was simulated for a complete year using weather data of the moderate Dutch climate. The most efficient systems prove to be the systems that decrease the heat gain by solar radiation. These systems can decrease the number of overheating hours by up to 95%. Increasing the thermal resistance value of a roof could lead to adverse results. The study shows an integrated approach that could be implemented in policies and regulations for the thermal assessment of holistic flat roof systems

This paper focuses on utilizing the Celciushouse as an escape room in energy education. In a broader context, it also addresses the incorporation of serious gaming in education. The project is part of COVE SEED. SEED - Sustainable Energy Education, aims to develop innovative vocational education and training, working with experts from five different European regions to phase out fossil fuels and contributing to Europe becoming a fossil free energy continent. SEED is a CoVE (Centres of Vocational Excellence) programme. CoVE’s are part of the Erasmus+ program aiming to establish transnational platforms on, among others, regional development, innovation and inclusion. SEED combines education on various international levels including level 2,3,4, and 6. At this moment, the project ESCAPEROOM IN ENERGY EDUCATION is still in its initial phase. With this paper and the accompanying workshop, we aim to gather insights from other international regions involved in the SEED project collaboration. The acceleration of technological developments means that what is learned today may be outdated tomorrow. Therefore, it is essential for educational institutions to focus on developing general skills such as critical thinking, problem-solving, and the ability to quickly absorb new information. The market demands professionals with modern knowledge and skills. Techniques taught to students today may become outdated tomorrow. Therefore, the ability to learn how to learn is becoming increasingly crucial. Analytical and research skills are therefore gaining importance. It is also essential for students to utilize various learning methods. Not just learning from books but particularly learning from practical experience. Practice-oriented learning, where students gain direct experience in real situations, not only reinforces theoretical knowledge but also develops practical skills that are valuable in the job market. To tackle these problems, serious gaming or the establishment of escape rooms can be a solution.

This article provides a nano (hyperlocal) view of climate change mitigation by viewing regenerative organizing through the eyes (as well as bodies and senses, etc.) of the households engaged in community-based energy projects. By showing what humans make up for in the largely absent relationship between nature and technology in these projects, we envision an incremental extension of the literature on community-based energy. The radically different contribution we aim to make is a tripartite imbrication that brings in natural agency alongside the human and the technical but specifies precisely how nano (smaller than micro) embodied practices afford mis- and realignments. https://doi.org/10.1177/1086026619886841 LinkedIn: https://www.linkedin.com/in/helenkopnina/

Thermal comfort is determined by the combined effect of the six thermal comfort parameters: temperature, air moisture content, thermal radiation, air relative velocity, personal activity and clothing level as formulated by Fanger through his double heat balance equations. In conventional air conditioning systems, air temperature is the parameter that is normally controlled whilst others are assumed to have values within the specified ranges at the design stage. In Fanger’s double heat balance equation, thermal radiation factor appears as the mean radiant temperature (MRT), however, its impact on thermal comfort is often ignored. This paper discusses the impacts of the thermal radiation field which takes the forms of mean radiant temperature and radiation asymmetry on thermal comfort, building energy consumption and air-conditioning control. Several conditions and applications in which the effects of mean radiant temperature and radiation asymmetry cannot be ignored are discussed. Several misinterpretations that arise from the formula relating mean radiant temperature and the operative temperature are highlighted, coupled with a discussion on the lack of reliable and affordable devices that measure this parameter. The usefulness of the concept of the operative temperature as a measure of combined effect of mean radiant and air temperatures on occupant’s thermal comfort is critically questioned, especially in relation to the control strategy based on this derived parameter. Examples of systems which deliver comfort using thermal radiation are presented. Finally, the paper presents various options that need to be considered in the efforts to mitigate the impacts of the thermal radiant field on the occupants’ thermal comfort and building energy consumption.

In Nederland verleent ongeveer een derde van de volwassen bevolking onbetaalde zorg. Het verlenen van mantelzorg kan in normale tijden zeer belastend zijn, maar de impact van een volksgezondheidscrisis op mantelzorgers is grotendeels onbekend. Deze studie richt zich op de vraag hoe de belasting van mantelzorgers veranderde na de COVID-19 pandemie en welke kenmerken verband hielden met deze veranderingen. We gebruiken zelfgerapporteerde gegevens van een steekproef van 965 mantelzorgers uit Nederland na 3 maanden pandemie om te onderzoeken hoe de objectieve belasting (d.w.z. uren besteed aan mantelzorg) en de subjectieve belasting waren veranderd, en wat hun zorggerelateerde kwaliteit van leven (CarerQol) was. We vonden dat de subjectieve belasting gemiddeld licht was toegenomen (van 4,75 naar 5,04 op een schaal van 0-10). Uit onze analyse bleek echter dat sommige zorgverleners er meer last van hadden dan anderen. De zwaarst getroffen zorgverleners waren vrouwen, met een laag inkomen, een betere lichamelijke gezondheid, een verminderde psychische gezondheid, zorgtaken voor kinderen, een langere duur van de zorg en zorgverleners die zorgden voor iemand met een verminderde lichamelijke en psychische gezondheid. Gemiddeld bleef de tijd die aan zorg werd besteed gelijk (een mediaan van 15 uur per week), maar bepaalde groepen zorgverleners ervoeren wel een verandering, namelijk degenen die zorg verleenden aan mensen in een instelling en aan mensen met een betere psychologische gezondheid vóór de pandemie. Bovendien hadden zorgverleners die veranderingen in objectieve belasting ervoeren niet dezelfde kenmerken als degenen die veranderingen in ervaren belasting en kwaliteit van leven ervoeren. Dit laat zien dat de gevolgen van een volksgezondheidscrisis voor zorgverleners niet kunnen worden gevangen door alleen te kijken naar objectieve of subjectieve belastingsmaten of kwaliteit van leven. Beleid voor langdurige zorg dat erop gericht is zorgverleners te ondersteunen om vol te houden tijdens een toekomstige crisis, moet gericht zijn op zorgverleners met een verhoogd risico op subjectieve belasting en een lagere CarerQol, zoals vrouwen, mensen met een laag inkomen en mensen met zorgtaken. Dergelijk beleid moet er rekening mee houden dat een vermindering van de objectieve belasting niet noodzakelijk leidt tot een vermindering van de subjectieve belasting voor alle zorgverleners.

Aim and objectives: To provide an in-depth insight into the barriers, facilitators and needs of district nurses and nurse assistants on using patient outcomes in district nursing care. Background: As healthcare demands grow, particularly in district nursing, there is a significant need to understand how to systematically measure and improve patient outcomes in this setting. Further investigation is needed to identify the barriers and facilitators for effective implementation. Design: A multi-method qualitative study. Methods: Open-ended questions of a survey study (N = 132) were supplemented with in-depth online focus group interviews involving district nurses and nurse assistants (N = 26) in the Netherlands. Data were analysed using thematic analysis. Results: Different barriers, facilitators and needs were identified and compiled into 16 preconditions for using outcomes in district nursing care. These preconditions were summarised into six overarching themes: follow the steps of a learning healthcare system; provide patient-centred care; promote the professional's autonomy, attitude, knowledge and skills; enhance shared responsibility and collaborations within and outside organisational boundaries; prioritise and invest in the use of outcomes; and boost the unity and appreciation for district nursing care. Conclusions: The preconditions identified in this study are crucial for nurses, care providers, policymakers and payers in implementing the use of patient outcomes in district nursing practice. Further exploration of appropriate strategies is necessary for a successful implementation. Relevance to clinical practice: This study represents a significant step towards implementing the use of patient outcomes in district nursing care. While most research has focused on hospitals and general practitioner settings, this study focuses on the needs for district nursing care. By identifying 16 key preconditions across themes such as patient-centred care, professional autonomy and unity, the findings offer valuable guidance for integrating a learning healthcare system that prioritises the measurement and continuous improvement of patient outcomes in district nursing.

The circular economy (CE) is heralded as reducing material use and emissions while providing more jobs and growth. We explored this narrative in a series of expert workshops, basing ourselves on theories, methods and findings from science fields such as global environmental input-output analysis, business modelling, industrial organisation, innovation sciences and transition studies. Our findings indicate that this dominant narrative suffers from at least three inconvenient truths. First, CE can lead to loss of GDP. Each doubling of product lifetimes will halve the related industrial production, while the required design changes may cost little. Second, the same mechanism can create losses of production jobs. This may not be compensated by extra maintenance, repair or refurbishing activities. Finally, ‘Product-as-a-Service’ business models supported by platform technologies are crucial for a CE transition. But by transforming consumers from owners to users, they lose independence and do not share in any value enhancement of assets (e.g., houses). As shown by Uber and AirBNB, platforms tend to concentrate power and value with providers, dramatically affecting the distribution of wealth. The real win-win potential of circularity is that the same societal welfare may be achieved with less production and fewer working hours, resulting in more leisure time. But it is perfectly possible that powerful platform providers capture most added value and channel that to their elite owners, at the expense of the purchasing power of ordinary people working fewer hours. Similar undesirable distributional effects may occur at the global scale: the service economies in the Global North may benefit from the additional repair and refurbishment activities, while economies in the Global South that are more oriented towards primary production will see these activities shrink. It is essential that CE research comes to grips with such effects. Furthermore, governance approaches mitigating unfair distribution of power and value are hence essential for a successful circularity transition.
