Investigating the Relationship Between Thermal Comfort and Human Psychology: A Review
Mehmet Furkan Özbey, Cihan Turhan
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 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.

Modification in the (NEN-)EN-ISO 7730 Model, with Regard of the Thermal Indoor Climate Assessment in Dutch Offices
Paul Roelofsen, Kaspar Jansen
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 also in the context of the Well certification of buildings for instance. Several studies show that the deviation between the Predicted Mean Vote (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.

Research Process of Recycled Cement Based on Life Cycle Assessment
Jiangwei Zhang, Zhengheng Huang, Zhishuai Zhu, Shuaiyin Yang, Junxiao Wei
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.

In 2020, the Chinese government made a clear international commitment to "carbon peak and carbon neutrality." The construction industry is a major emitter of greenhouse gases, posing a significant challenge to achieving the goal of "carbon peak and carbon neutrality." The development of low-carbon buildings can play a crucial role in reducing GHG emissions. China's low-carbon construction industry is experiencing continuous growth, and the building materials market is also evolving. To capitalize on the significant opportunity presented by the development of low-carbon construction, this paper delves into the background of the low-carbon economy. Firstly, the paper summarizes the impact of the low-carbon economy on the cost management of new green building materials. It then analyzes the current challenges facing the cost management of building materials in Chinese construction enterprises. Finally, it discusses strategies for enhancing the cost management of building materials within enterprises. This study aims to provide construction companies with valuable insights into the cost management of new green materials, enabling them to minimize capital expenditure through the implementation of scientific and strategic management practices.

Green Infrastructure as a Strategy for Building Resilience Against Stormwater in Ibadan
Rasheed Sekore Busari, Oludare Akeem Adedeji
Green Infrastructure provides cities with a wide range of benefits and solves myriads of problems facing the settlements. The study is aimed at examining the application of geospatial technologies to the environmental destruction problem facing Ibadan in the area of stormwater management. Data for the study were obtained from remote sensing, local observation and base map of the local governments making Ibadan core area. The data obtained were further validated using global positioning system for effective classification of the land uses and flooding classification. The analysis of the study made use of ArcGIS 10.3 and quantitative changes in land use pattern were obtained between 2000 and 2020 on a regular epoch of five years, Normalized Difference Vegetative Index (NDVI) and Digital Elevation Model (DEM). The infill development of Ibadan has drastically reduced the green space from 37.64% in the year 2000 to 22.84% in the year 2020 and built up rose from 51.97% in the year 2000 to 69.04% in the year 2020 and absence of green infrastructure in high flood zones areas .The continuous decrease in the coverage of green infrastructure due to increase in anthropogenic activities has actually disrupted the structural integrity of the greens for environmental sustainability of the city and areas with high flood zones were not covered with any green infrastructure. It is therefore recommended that reduction in the built up and paved areas, and adequate green infrastructure management in the city can reduce the excessive stormwater in various settlement patterns of the city, and build resilience against this problem.
