“…When the temperature is high and certain measures are not taken, the environmental humidity will decrease, and the human perception of discomfort will become increasingly evident (Fan et al, 2017; Leung et al, 2017). In a relatively dry environment, older adults may have irritability and other manifestations, which could increase the risk of cardiovascular disease (Guerry et al, 2019). Previous studies have shown that 18–25 °C (64.4–77 °F), in general, is the most comfortable temperature range for them, which not only maintains a thermal balance in the body but also limits the impact on their everyday life (Tuaycharoen, 2020).…”

Objectives: To evaluate the aspects of the objective physical environments of five residential care facilities (RCFs) for older adults and the residents’ subjective perceptions of these aspects. Background: The physical environment in RCFs impacts the health and comfort of the residents. However, the design standards for RCFs lack details which can result in insufficient living conditions. Methods: Through questionnaire surveys, older adults’ satisfaction on the degree of the light, acoustic, and thermal environment in the facilities was obtained. Indoor lighting condition was measured by an illuminance meter in lux, sound pressure level (SPL) with sound level meters in dBA, and temperature in °C with a temperature data logger, and an audiometer was used to test the hearing of the older adults. Results: A total of 480 questionnaires were obtained. Results show that (a) older adults need an appropriate light environment to avoid the negative impact of limited light, (b) poor acoustic environment could affect their mood and health, and (c) when the room temperature is within the range of 20–26 °C (68–78.8 °F), they feel most comfortable. When the appropriate temperature and humidity, balanced illumination, and SPL meet the needs of older adults, it can provide a more comfortable physical environment for them. Conclusion: Examining the interaction between the physical environmental factors that affect older adults in RCFs is important for the design of residential housing and provides more theoretical support for research on the influence of the physical environment on the quality of life of older adults.

“…Improved visual comfort, i.e., light conditions, contributes to the improvement of quality of life, prevention of falls and improvement in ambulatory ability, especially among older persons with low vision. In this context, optimal contrast by the use of colors in the living environment where the older person spends a substantial amount of time can prevent falls [12]. In particular, some pathologies in older people, e.g.…”

“…Several studies have recently focused on integrating IEQ and elderly people in order to develop elderly-friendly interiors, particularly for care facilities. The approach to this issue is related to elderly room interior design, which includes indoor air quality [6][7][8], visual comfort [9,10], acoustical comfort [11,12], and thermal comfort [13][14][15]. The literature highlights that, due to strong correlations between IEQ components, changing just one of them could have negative effects on the others.…”

It is known that the elderly usually spend the last years of their lives indoors, with little contact with others and the outside environment. Indoor environmental quality (IEQ) conditions related to lighting, air quality, thermal comfort, and acoustics directly affect their quality of life. In this study, the main focus is on the design of institutional care rooms for elderly people to create an indoor comfort. However, considering all four factors of IEQ in one model is a challenging task. A multi-objective problem is formulated based on a weighted sum of IEQ components in a parametric modelling environment using computational design methods. Several simulation tools are utilised, and a Self-Adaptive Ensemble Differential Evolution Algorithm is proposed to tackle this complex problem. The results show that optimal ranges for each IEQ component are achieved, with average values reaching 72% of the ideal benchmarks after the algorithm is converged. Results reveal strong correlations between IEQ components. This significant improvement in indoor environmental quality (IEQ) demonstrates the efficacy of the optimisation algorithm used. This study emphasises the flexibility and relevance of these findings for wider implementation in similar settings.
