Thermal Comfort Assessment in The Open Space in Bandung Case Study Dago Street and Riau Street

It is important to improve residential thermal comfort in the high dense cities, in which wind environment is crucial. Waterside buildings take an advantage of micro-hydrological-climate in summer that should be used to enhance residential thermal comfort especially in the subtropical region. In order to propose design approaches according to the outdoor thermal comfort of the waterside residential, a case study of Shenzhen She Kou residential district has been made. It focused on various factors that could have influence on wind environment for improving thermal comfort. Using wind velocity ratio (ΔRi) criterion, factors of building development volume, building direction and layout pattern, open space arrangement etc. have been broadly explored using FLUENT simulation. To planning parameters, the Floor Area Ratio (FAR) is significantly influence wind environment, the smaller FAR is better. To the vertical layout of the buildings, multi-storey layout and multi-storey & sub high-rise mixed layout would provide better wind environment. To the horizontal layout, the determinant is better than the peripheral. Other factors such as the buildings’ direction towards the road, buildings’ height, and open space setting, have influence on wind environment yet. In general, the more benefit of design layout for wind breezing, the better wind environment it could get

The present study is based on the assumption that the urban heat island (UHI) mitigation appears compelling and urgent in dense cities. To the above thematic area, recent redevelopmental interventions of open space for the microclimatic improvement and thermal comfort have been made through national and international programs at neighborhood scale (local area). One of these recovery processes is the case study of Pavlou Mela in the Greek context, which in the present discussion, focuses on the microspecific investigation through quantitative analysis of the eleven points distributed in the area of the intervention, extrapolating comparative considerations of different configurative factors post-operam. The results of this analysis tend: (i) To identify the degree of accuracy of the two most applied software packages in the scientific community (ENVImet Pro and Rayman Pro) through microclimatic parameters, namely air temperature (Ta) and surface temperature (Ts) comparing them with in-situ measurements; (ii) to evaluate the thermal sensation of man correlated with the mean radiant temperature (Tmrt) by verifying the actual improvement of thermal comfort outdoor with the index, physiologically equivalent temperature (PET).

Stress Levels

Working people spend around 54% of their waking hours at a workplace, according to recent statistics. Work-related stress is unavoidable, and it can damage the health of employees and affect business performance. In this paper, we argue that open space inside the workplace environment can have a positive influence on reducing overall stress levels in all the categories of users. To our knowledge, there is a significant lack of research considering specific business districts and the gated complexes called business parks, especially in post-socialist Eastern European cities, where there they are still a novelty. Empirical research in this study is on the single case study of Business Park “Airport city” in Belgrade, Serbia. Its main focus is on the survey conducted with 235 participants based on a questionnaire, which examines the relation between workplace stress and workplace environments. The findings from the questionnaire show that the frequency, duration, and activity of open space usage influence the stress levels of employees in this specific workplace, while it is not visible relating to their age and gender. Additionally, final implications suggest that improved open space, such as well-expected greenery, but also the urban design non-associative to workspace and the socialization and exercise amenities customized for frequent and short work breaks, can facilitate the overall well-being of employees. They are innovative elements in relatively underdeveloped research on stress measures with open space usage characteristics in the specific (gated) workplace setting.

Indoor Conditions

The adaptation of spaces to different usage typologies can be complex in heritage buildings. Facilities were initially planned for a specific type of use that, when changed, require additional measures to ensure a suitable indoor environment. Passive strategies—e.g., free cooling—are commonly used as an alternative without requiring equipment installation. However, its implementation often leads to unsatisfactory conditions. Therefore, it is important to clarify the main barriers to achieving thermal comfort in readapted historic buildings. The present work investigates the thermal comfort conditions reported by workers in office spaces of a historic building in the University of Coimbra. A monitoring campaign was carried out between May and September 2020 to assess indoor conditions’ quality. Due to the current pandemic of COVID-19, offices were not occupied at full capacity. A one-day evaluation of thermal comfort was made using a climate analyzer and six occupants were surveyed on 19 August 2020. The main results highlighted discomfort due to overheating of spaces. The causes were related to the combination of inadequate implementation of the free cooling actions and the building use. Furthermore, it was recommended the installation of HVAC systems in case of full capacity.

Occupant Satisfaction

The analysis of thermal comfort in buildings, energy consumption, and occupant satisfaction is crucial to influencing the architectural design methodologies of the future. However, research in these fields in developing countries is sectorised. Most times, the standards to study and assess thermal comfort such as ASHRAE Standard 55, EN 15251, and ISO 7730 are insufficient and not appropriate for the geographical areas of application. This article presents a scoping review of published work in Colombia, as a representative case study, to highlight the state-of-the-art, research trends, gaps, and potential areas for further development. It examines the amount, origin, extent, and content of research and peer-reviewed documentation over the last decades. The findings allow new insights regarding the preferred models and the evaluation tools that have been used to date and that are recommended to use in the future. It also includes additional information regarding the most and least studied regions, cities, and climates in the country. This work could be of interest for the academic community and policymakers in the areas related to indoor and urban climate management and energy efficiency.

Place-based activism has played a critical role in the history of urban and environmental politics in California. This article explores the continuing significance of environmental place making to grassroots politics through a case study of Friends of Rose Canyon, an environmental group in San Diego. Based in the fast-growing University City neighborhood, Friends of Rose Canyon waged a long, successful campaign between 2002 and 2018 to prevent construction of a bridge in the Rose Canyon Open Space Park in their community. Using historical and participant observer methodologies, this study reveals how twenty-first-century California urbanites claimed and created meaningful local places and mobilized effective politics around them. It illuminates the critical role of individual activists; suggests practical, replicable strategies for community mobilization; and demonstrates the significant impact of local activism at the urban and metropolitan scales.
