Indoor Environment Quality

The amount of time people spend inside buildings is significant. Indoor environment quality deficiencies in some of these buildings may affect the health of its users. Therefore, a systematic literature review has been conducted to assess the quality of indoor environments in existing buildings in Latin America. The objectives of this review are (1) identifying countries and building types whose indoor environment quality has been analyzed the most, (2) identifying most used evaluation strategies, (3) identifying comfort types and most evaluated variables, and (4) determining whether or not Latin American buildings are comfortable and what local factors contribute to that effect. From the 100 selected papers for this analysis, it was noted that Brazil and Argentina led the studies on residences and schools. It was also noted that hygrothermal comfort was the most analyzed comfort type, with temperature and humidity leading the number of studies. Finally, this review shows a lack of studies including buildings whose users are sensitive to indoor environmental quality, such as nurseries, senior homes, or health facilities. Additionally, there is a sustained discrepancy between objective measuring methods and user perception. Furthermore, a detailed analysis of 88 buildings shows that in Latin America, 67.5% of buildings are uncomfortable; thus, it is necessary to improve the designs and regulatory standards, to educate users, and to improve building monitoring management at the operational stage.

The State Of Kuwait

In this study, indoor quality and environmental comfort were investigated in secondary school buildings located in the State of Kuwait. Comfort variables such as temperature and relative humidity (thermal comfort), noise (acoustic comfort), illumination (visual comfort), as well as allocated classroom floor area per student (spatial comfort) were measured. Data was collected over a 7-month period on a spot basis during school hours in student-occupied classrooms at 46 selected schools. The measured data was then compared to international guidelines and standards related to indoor environment quality. The data for noise and allocated space were shown to be in the comfort ranges in all the schools. However, 11% of the schools are not adequately illuminated, 33% had temperatures not within the recommended limits, and 22% of the schools had humidity levels either higher or lower than the recommended levels. Also, 9% of the schools had low illumination readings.In addition, during the data monitoring, a survey was conducted by which the student occupants completed a questionnaire so that subjective and objective evaluations could be compared. The findings of the questionnaire displayed significant correlations between the measured data and some ailments and other complaints experienced by the students.Ultimately, the results found in this research will provide a baseline for comparison with future indoor environment quality assessments in buildings. Furthermore, recommendations are suggested in order to improve the environmental quality problems encountered in some of the schools, which may be beneficial for policymakers, facilities managers, and design engineers.

The present study emphases the numerical investigation of the change in the overall indoor environment of a mechanically heated room, due to alteration in direction of the cold air stream at the inlet. This study is important to find the correlation between the configuration of altered geometry on the indoor environment quality and human comfort. Different case studies have been studied by altering the direction of the flow of the unidirectional velocity vector (U) by turning clockwise around the Z-axis and keeping other geometry parameters unaltered. Numerically simulated observations have been analyzed to study the effect of changed airflow direction at the inlet on indoor environmental quality Slight variations in the indoor environment were observed due to changed inlet angle set from 0°-60°, but for the largest angle setting of (80°), considerable changes were observed ins temperature and flow patterns. When the inlet vent angle increased from 0°-80°, the airflow and thermal pattern in room changes. More swirls and circulation observed in the case of higher inlet angles. PPD values for subsequent cases were found under control for all the set of inlet angles. The lowest PPD and PMV values observed for an 80° inlet angle setting. The outcomes of the research would be valuable for the design and optimization of local buildings and more energy can be hoarded by proper installations of equipment and inlet vent location

Health And Well Being

Indoor environments have a large impact on health and well-being, so it is important to understand what makes them healthy and sustainable. There is substantial knowledge on individual factors and their effects, though understanding how factors interact and what role occupants play in these interactions (both causative and receptive) is lacking. We aimed to: (i) explore interactions between factors and potential risks if these are not considered from holistic perspective; and (ii) identify components needed to advance research on indoor environments. The paper is based on collaboration between researchers from disciplines covering technical, behavioural, and medical perspectives. Outcomes were identified through literature reviews, discussions and workshops with invited experts and representatives from various stakeholder groups. Four themes emerged and were discussed with an emphasis on occupant health: (a) the bio-psycho-social aspects of health; (b) interaction between occupants, buildings and indoor environment; (c) climate change and its impact on indoor environment quality, thermal comfort and health; and (d) energy efficiency measures and indoor environment. To advance the relevant research, the indoor environment must be considered a dynamic and complex system with multiple interactions. This calls for a transdisciplinary and holistic approach and effective collaboration with various stakeholders.

There is limited research that considers students with migratory background cultural characteristics within vocational counseling processes in high schools of the United States, Latin America, and South Europe. A systematic literature review was made, guided by the question: In young migrants and second-generation migrants, how vocational counseling influences the achievement of being admitted into a university, comparing their life trajectories during secondary and high school? A total of ten articles, out of three hundred eleven initially found, were selected based on a protocol for the literature review (available on request). All these articles belong to the United States context. One also considered the Spain reality. Based on the protocol used, neither another Southern Europe article, nor any article on the Latin American context was selected. All the analyzed articles pointed up the central role of counseling processes regarding students' vocational decisions. Nonetheless, there is not much attention to counseling processes given to students with a migratory background and their specific needs. Among others, this fact reveals one of the failures of the system in giving post-secondary opportunities to these students. Limitations and recommendations to improve the vocational counseling processes and their influence on the achievement of admission into a university for these students are presented. Besides, some gender differences and the transcendental role of families in the vocational decisions of students are analyzed within the literature review.

AbstractResearch about indoor comfort in future years will increasingly be guided by the pressing need for decarbonizing the built environment due to climate change. Health, efficiency, and satisfaction of work and the feeling of comfort are largely determined by the interior criteria. The sustainable indoor environment is a result of complex factors: air conditioning (ventilation), indoor temperature, heating methods, lighting, and acoustic. This chapter explores and analyzes climatic, cultural, and behavioral factors that play an important role and have an influence on technology for an indoor regenerative environment. This chapter is based on an explorative literature review and reflects indoor environmental quality, users’ expectations, and users’ behavior from the perspective of different scientific disciplines. Current standards are based on a rational approach to thermal comfort, and indicators are determined on the measured subjects’ reactions during stabilized conditions in climatic chambers. It is concluded from these results that people in different environmental conditions react similarly to everyday life. Nevertheless, survey results suggest that achieving the optimal level of the indoor environment is possible when climatic, cultural, and social context is taken into account.

Window Design

Windows are elements of great incidence on building consumption and therefore with great saving potential. When designing high-energy efficiency windows, it is possible to negatively influence the indoor environment quality. To ensure indoor environmental quality, hygrothermal comfort, acoustic comfort, luminous comfort, physical-chemical and microbiological contaminants in the air, and the electromagnetic environment must be considered.  Of all these aspects, windows intervene in four of them:  hygrothermal comfort, luminous comfort, acoustic comfort and air quality. In order to carry out a comprehensive design, designers should study in detail the variables mentioned for each particular case and, consequently, act. This, due to the means and the deadlines with which the prescriber usually counts on, is currently not viable. This research responds to current deficiencies by proposing the development of a product indicator through an integrative procedure for window design that simultaneously contemplates indoor environmental quality, energy efficiency and cost, integrating environmental and socio-economic aspects. The indicator proposed here provides information substantially superior to that currently available to technicians, to be used as a decision making tool.

Level Of Importance

This study investigated the level of management’s perception of the importance of indoor environment indicators at longterm care facilities as well as the differences between the level of perceived importance and the level of implementation. This study also analyzed the indicators for improving indoor environments. This study selected Taiwanese longterm care facility managers as its subjects to whom questionnaires were distributed by mail. Descriptive statistics, a one-way analysis of variance (ANOVA), and an importanceperformance analysis were used to conduct analyses on the data retrieved from the questionnaires. The results indicate that, of the indoor environment indicators of four facility spaces, bedrooms had the highest perceived level of importance. The lounge was the easiest space in which to implement the indicators. Differences were found between the perceived level of importance and the level of implementation for six of the indoor environment indicators of the four facility spaces. In these four spaces, the ventilation indicator was the most important, whereas implementing the temperature and humidity indicators was the most difficult. The highest priority for indicator improvement was given to the temperature in the bedrooms and bathrooms, whereas control over temperature, humidity, and sound had a low priority. The indicators seen as requiring continuous maintenance were lighting and ventilation. Facility managers had a high level of awareness and competence in implementing the ventilation indicator. However, although they were aware of the importance of the temperature, humidity, and sound indicators, their implementation was difficult, suggesting that they needed to be improved.

Indoor Environment Quality

This study aimed to evaluate the link between health problems, demographic factors, and the indoor environment quality of residents in Indonesia. We conducted a cross-sectional design study through a questionnaire survey with 443 respondents aged between 12 and 81 years. The questionnaire was concerned with previous health problem occurrences associated with thermal discomfort experiences, indoor environments, economic conditions, and basic anthropometric factors. Logistic regression with the odds ratio (OR) was applied to evaluate the tendency of different respondent groups to suffer from certain health problems, when compared to reference groups. Furthermore, structural equation modelling (SEM) was used to incorporate certain factors (economic conditions, thermal discomfort experiences, and perceived indoor environments) into a single model to understand their direct and indirect effects on health conditions. The results indicate that economic conditions are the most significantly associated with health problems. Furthermore, we found that the low-income group was the most vulnerable to health problems, including coughing, puking, diarrhoea, odynophagia, headaches, fatigue, rheumatism, fidgeting, skin rashes, muscle cramps, and insomnia (OR: 1.94–6.04, p <0.05). Additionally, the SEM suggested that the respondents’ economic conditions and thermal discomfort experiences had significant direct effects on their health problems with standardized estimates of -0.29 and 0.55, respectively. Additionally, perceived indoor environment quality, which is possible to cause thermal discomfort experience, indirectly affect health problems. These findings contribute an insightful and intuitive knowledge base which can aid health assessments associated with demographic and physical environments in developing sustainable and healthy environment strategies for the future.

Comfort Criteria

The research discussed the application of indoor health and comfort criteria that needed to be reviewed to create good indoor environmental quality and reduce the transmission of the Covid-19 virus where people spent most of their time indoors. A confined area, which was poorly ventilated and reliant on air conditioning, helped transmit the Covid-19 virus easily as air recirculation was the main cause of office clusters. One of the categories of Greenship Interior Space, Indoor Health and Comfort (IHC), could be used as a guide for creating better indoor quality. The method used for the research was a systematic literature review to define, study, analyze, and classify all available research relating to adaptation of indoor health and comfort criteria to mitigate the transmission in the workplace. The results show the adjustment to IHC criteria in IHC 1-10, which focus on providing good air quality by introducing outside air, stopping air recirculation, reducing indoor user capacity, and reducing indoor biological and chemical pollutants. To illustrate the implementation of the new normal, Ciputra University workplace was being observed, as the findings of the results, some strategies that are in line with the objectives of IHC 1, IHC 2, and IHC 5. Adjustment of these criteria must be supported by implementing health protocols through basic hygiene routines, fitness screening, and maintaining physical distancing.
