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.

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.

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?
