The state of mind is a crucial factor in thermal sensation and should be thoroughly understood in studies of thermal comfort while integrating human psychology into the literature. Fanger's predicted mean vote (PMV) and predicted percentage of dissatisfied percentage of dissatisfied (PPD) method is a cornerstone in thermal comfort research. On the other hand, the adaptive thermal comfort (ATC) model provides a broader perspective by including behavioral and psychological adjustments, along with the personal and environmental parameters outlined in Fanger's PMV/PPD method. However, literature investigates the ATC model predominantly focuses on behavioral adaptations, neglecting psychological adjustments emphasized by ASHRAE as integral to "the state of mind. Moreover, qualitative approaches dominate the literature, with limited quantitative investigations. Therefore, this paper aims to address the importance of human psychology by systematically reviewing previous field studies to elucidate the magnitude and significance of psychological adjustments to the thermal comfort. Additionally, it introduces the Turhan and Özbey coefficients, derived from a quantitative study, to provide a more comprehensive understanding of the impact of psychological factors on thermal comfort. This work is highlighted the importance of the human psychology to achieve better indoor environmental quality in aspects of thermal comfort.

Where previously the thermal indoor climate in a Dutch office was mainly assessed on the basis of sedentary activities, one must now also take into account activities associated with a higher metabolic rate to improve health by reducing sitting. This subject is receiving attention in the Netherlands; so in the context of the Well certification of buildings for instance. Several studies show that the deviation between the PMV and the experimental results increases as the temperature and/or the activity increases. This technical note is a proposal to modify the calculation of the PMV for metabolisms up to 2.1 met, on the warm side of the thermal sensation scale, in the same way as Fanger describes in his thesis, using research results as they are currently available in the literature, excluding the adaptive thermal comfort aspect.

Utilizing recycled aggregate concrete (RAC) is important because it solves the problems of resource scarcity and pollution from urban waste. Using RAC will have a significant positive environmental impact over time. Many studies compare the environmental benefits of RAC with natural aggregate concrete (NAC) and use life cycle assessment (LCA) to analyze the benefits of RAC. However, a mature and comprehensive research system for LCA application in RAC has yet to be developed. The purpose of this study is to review the environmental impacts of RAC throughout its life cycle using the novel perspective of the four steps of LCA, identify methods to address or mitigate biases, and suggest future development directions for this technology and database improvement to provide useful references for future research. The findings show that all four stages of LCA (goal and scope definition, life cycle inventory analysis, life cycle impact assessment, and life cycle interpretation) have issues, primarily related to data measurement and selection, process step assumptions and simplifications, and algorithm limitations. We also recommend using the life cycle basic function evolution method to optimize Monte Carlo simulations, which reduces the uncertainty of LCA results. In the future outcomes of LCA ought to emphasize on the carbonation process and the analysis phase of cement's second life cycle.

The Chinese government vowed to achieve "carbon peak and carbon neutrality" on a global scale in 2020. Since the building sector emits a significant amount of greenhouse gases, achieving the "carbon peak and carbon neutrality" goal will be extremely difficult. Emissions of greenhouse gases can be greatly decreased by developing low-carbon buildings. As more and more new green building materials hit the market, China's low-carbon construction sector is growing along with the building materials market. This study does a thorough analysis of the literature on the most recent advancements in cost management related to new eco-friendly construction materials in low-carbon economies. The objective is to describe the different dimensions of information green building materials cost management, uncover the underlying themes and sub-themes within these dimensions, identify key research gaps in the current studies, and provide recommendations for future research endeavors. Through the review of the literature, the existing problems in the cost management of new green building materials are revealed. And from the improvement of new green building materials cost management way is elaborated. The conclusion of this paper is that the existing research mainly focuses on the construction of cost management systems and does not systematically study the formation process of material costs, ignoring the consideration of material research and development technology, environmental accounting disclosure and other aspects. Finally, the research project ought to prioritize material research and development, strengthening the cost accounting system, environmental cost disclosure, improving the material management system, and other areas that require in-depth investigation.

Insufficiency and near absence of green infrastructure (GI) which have been shown to offer cost-effective nature-based solutions in mitigating urban flood and managing stormwater in major cities in Nigeria have increased their vulnerability to destructive floods in recent years. This study conducted a spatial assessment of GI and its potential effectiveness on stormwater management in Ibadan, Nigeria, with the use of remotely sensed data. Change detection between 2000 and 2020 was conducted based on four land use categories (built-up, green area, bare surface, and water bodies) because it coincided the period of rapid land use changes and occurrence of devastating flooding in the city and environs. Normalized Difference Vegetative Index (NDVI) calculated from Landsat image data and Digital Elevation Model (DEM) data to determine areas liable to flooding were also assessed using geospatial analysis. The results showed that the infill development of Ibadan has drastically reduced the available GI from 37.64% in the year 2000 to 22.84% in the year 2020 while built-up areas increased from 51.97% in the year 2000 to 69.04% in the year 2020. In 2000, NDVI ranged from -0.37 to 0.02 in the inner city showing poor vegetation. By 2020 the elements of GI are mostly fragmented with small coverage and more than 70% of the area occupied by built-up areas without vegetation cover. Vegetal cover decreased with time due to increasing impervious surfaces, creating many high flood zones and stormwater. It is concluded that provision and effective management of GI in the city can serve as a valuable tool to mitigate the problems of excessive stormwater.

Vietnam battles severe air pollution and substandard infrastructure, leading to sick building syndrome (SBS), even in healthcare facilities. Enhancing indoor air quality (IAQ) in hospital design and renovations is vital for safeguarding vulnerable groups, such as patients, children, and the elderly. However, akin to other developing nations, Vietnam must address specific local challenges before devising any strategies to improve IAQ in these critical settings. In this study, we identify factors influencing the selection of methods to improve IAQ in healthcare facilities, considering Vietnam's specific conditions. 16 potential factors have been investigated and categorised into 4 influence groups based on a comprehensive literature review and validated by a survey of 160 architects, engineers, project managers, and hospital staff. We conducted an academic literature review to pinpoint these factors and propose design solutions. Additionally, we surveyed and quantified the effects from the perspective of Vietnamese healthcare experts. Based on our findings, we discussed the impact of these factors and suggested solutions for enhancing IAQ during the design and renovation phases of hospitals. The study's contribution lies in its practical insights for stakeholders seeking to improve IAQ. The outcomes of this study aim to provide a foundation for developing guidelines and standards to assess construction quality in healthcare facilities.
