This study aims to clarify the correlation between thermal comfort and discomfort glare. The field survey was performed in office buildings located in Thailand using the comfort indices and the questionnaire survey. The agreement can be found with respect to the glazing performance and sensation level, and the comfort index evaluation must be carefully concerned, as there is a discrepancy in occupants’ responses. It is necessary to comprehensively study the effects of thermal comfort and discomfort glare separately, along with their interactions. The post-occupancy survey is required to optimally enhance the occupants’ comfort assessment.

The objective of this study is to develop guidelines for thermal comfort and energy efficiency for senior centers during winter. The study was conducted in Phitsanulok, Thailand and it applied 3 study’s methods; field survey, laboratory study, and simulation in scSTREAM–a CFD program and DOE-2 program; to develop the guidelines. With a temperature set-point at 25.0°C in the existing air-conditioned senior centers, the study shows that occupants feel "Slightly cool". These feeling can be adjusted to "Neutral" by applying natural ventilation and fans to generate air speed of 0.57–0.60 m/s during 8:00 AM–1:00 PM, and by setting the temperature set-point at 26.0°C with air speed of 0.10–0.26 m/s during 1:00 AM–4:00 PM. The guidelines can help reduce energy consumption by 23.0 % and can apply for senior centers.

This paper aims to examine a prospect of disaster education and community development at the Hua Takhe community, Thailand. It explores program and participation as well as meaning and implication of the Japanese case studies through field observations and participations. Based on the analysis of the questionnaire survey of its inhabitants, the strengths of the Hua Takhe community include solidarity, human and cultural resources, and location. Nonetheless, its weaknesses are limitation of disaster prevention-related resource, insufficient cooperation between the old and the young generation, lack of systematic disaster management, and low participation in disaster drills. While collaboration with educational institutions, informal and innovative learning, better quality of life, and being an example for other communities can be considered as its opportunities, changing ownership and usage of dwellings and unbalanced development can be its significant threats. Consequently, this paper proposes a disaster education and community development program focusing on enhancing the inclusive learning community, which contributes to the disaster resilience of the Thai communities.

Many countries propose indoor temperature set-points of air-conditioned offices to be comfortably sustainable and to reduce energy consumption. Even though there are recommendations for the optimum temperatureset-points, it is questionable how those values could be applied to the actual situation in a tropical region. This study aims to survey thermal performance and estimate thermal comfort in different set-points. In 2019, two air-conditioned office buildings were tested by increasing set-points from the actual value between 23 °C and 25 °C. Data loggers measuring thermal variables were installed in the offices and the questionnaire was distributed to evaluate human response. Considering the ASHRAE psychometric chart, thermal environments of both cases on the day of a normal set-point were low; falling inside in the 1.0 clo zone. Thermal environments gradually moved from the 1.0 clo zone to the 0.5 clo zone, however, some of them were out of both comfort zones due to high absolute humidity. The predicted mean vote (PMV) and the thermal sensation vote (TSV) show that the votes changed from the cold side to the neutral side, and the higher acceptance rate was at warmer temperatures. The comfort temperature calculated from Griffith’s method was found to be 23.6–25.1 °C which was lower than the measured operative temperature. Adaptive clothing behavior is described to confirm a better condition at warmer temperatures. A possibility of increasing cooling set-points at 24–25 °C is applicable to office buildings in the tropics to remain comfortable.

The increase in population ageing worldwide is giving rise to the design of age-friendly cities and facilities. Recognizing elderly needs is essential to promote an active life that enables continued participation in the society. However, there is no precedent that justifies the choices in the design of spaces for the elderly, so this study proposes an evaluative model of physical design that satisfies and fulfills the needs of the elderly. The Design Pyramid is based on the Theory of Maslow’s Hierarchy of Needs linking the needs of the elderly with architectural attributes. The application of this model allows evaluating the spatial design and its elements and exploring improvements to promote the well-being of the elderly.

In discussion on modern urban development issues, many researches have focused on those newly expanded areas, yet few researches have scrutinized what contributes to the vibrant life of the historical Central Business District (CBD) in inner cities. This research has examined a declined old city centre in central Taiwan by deploying Space Syntax analysis to verify possible contributions of parts-whole street network disconnection to the death of CBD in inner cities. The research findings suggest that linearity and critical street segments being properly integrated with the whole arterial street network could be crucial for future city planning.

Discomfort glare is perceived differently by the young and the elderly. However, the existing daylight glare formulae do not take the effects of age into account and the current limiting glare index was obtained from non-elderly subjects. To create lighting suitable for the Thai elderly, especially in terms of glare, two objectives were addressed. The first explored a modified formula of daylight glare for the Thai elderly, while the second investigated the limiting daylight glare index for the Thai elderly in particular areas of residential and public buildings. Both laboratory and field studies were undertaken. The former investigated a daylight glare formula modified for the effect of age of the Thai elderly. Experiments were carried out in a controlled chamber at Kasetsart University, Bangkok, Thailand. The latter explored the limiting daylight glare index for particular areas of residential and public buildings for the Thai elderly with studies conducted in the real environment. A modified formula was proposed to predict daylight glare for the Thai elderly. Limiting daylight glare indices for particular areas of both residential and public buildings for the Thai elderly were also proposed, and the recorded values were found to be higher than the existing limiting daylight glare indices.

Real estate amenities can create both benefits and costs to local community, which economists call externalities. Quantification of externalities is challenging because of potential endogeneity problems that render simple statistical analyses inaccurate, necessitating the use of a more rigorous econometric technique. Exploiting store expansion activities of Whole Foods Market to infer the causal impact of the Whole Foods Effect using the difference-in-differences strategy, we find that property prices within 0.5 mile of a new Whole Foods Market store increase on average by 6.7% after a new store opens.

An incessant challenge for the architects nowadays is how to design architectural projects that support the creation of meaningful experiences, benefitting from the interconnection between building materiality and human sensibility. The purpose of this study is to provide a phenomenological understanding of brick as an architectural material and how people perceive its architectural space and interpret its architectural meaning.Method of phenomenological analysis from Moustakas (1994) is adopted to guide the whole research procedures; using in-depth and multiple interviews with the users of three different buildings who shared experiences in inhibiting and interacting with the environment created with brick as an architectural material.
