“…Moreover, the economic increment in productivity can be higher than the annual energy and maintenance costs [69]. Al Horr et al [70] studied also workers' health and well-being in offices, concluding that SBS and thermal, visual, and acoustic comfort cannot be neglected in green building design. Kim et al [71] suggested that users' control over spatial variables can be a key aspect affecting people's satisfaction, self-reported productivity, or health in workplaces.…”

Abstract:In this work, the literature about the relationship between thermal comfort and productivity in workplaces is reviewed and explored by means of a co-citation analysis-i.e., a factor analysis applied to the mutual citations of the most relevant contributions. A structure of three main clusters of papers describing the relationships between workers' thermal comfort and productivity were identified according to the factor analysis and then confirmed with a multidimensional scaling. Results indicate that comfortable indoor thermal conditions can have beneficial impacts on workers' well-being and productivity, such as higher operational rates, lower production losses, fewer sick leaves, and reduced health related costs. Some authors proposed analytical and empirical expressions for the quantification of the impact of thermal comfort on productivity; nevertheless, due to the broad spectrum of activities and their applicability, the literature is still far from reaching a general consensus on the potential impact of comfort/discomfort on productivity and proposed models can vary significantly in the different studies.

“…This is a positive development in Malaysia, not only for the welfare of the citizens, but also for the economy of the country and its developers. However, the increase in the quantity of affordable housing does not guarantee improvements in the quality of the indoor environment (IEQ), which commonly affects people's comfort, health and productivity (Haghighat & Donnini, 1999;Lai et al, 2009;Frontczak & Wargocki, 2011;Al Horr et al, 2016). For example, one of the aspects of IEQ that influences residents' well-being is the thermal comfort of the space, such as temperature and ventilation (Persily, 2015;Nimlyat & Kandar 2015).…”

Malaysia is currently focusing on providing affordable housing all over the country, as part of the plan to tackle the problem of the rising costs of house ownership due to reasons such as the economic crisis and land limitations. However, a limited number of methodical studies have been conducted on residents' feedback on the indoor environment of affordable housing. Indoor Environmental Quality (IEQ) is an important aspect of occupants' wellbeing, as it affects their health and productivity. Therefore, evaluating residents' feedback on IEQ is an important step in gauging building performance and conditions. In addition, the health and productivity of residents needs to be evaluated in order to identify the effect of IEQ on them. A questionnaire survey was used to achieve the study objectives and to gain access to the respondents' views and feedback. The pilot questionnaire study was conducted at two housing apartments in Kuala Lumpur, Malaysia, and the data collected were evaluated and analyzed using SPSS software. The outcome of this pilot study is significant, as it shows the residents' dissatisfaction level towards IEQ factors such as noise, glare and privacy, and other aspects of IEQ that are important, such as ventilation. Additionally, it has been found that the IEQ of the residents does affect their health and productivity. It is anticipated that the outcome of this study will serve as an indicator of building performance improvements needed to achieve a better indoor environment quality for affordable housing in Malaysia.

“…In this context, a large amount of research has been developed for buildings of different types, with the major ones being offices, commercial buildings, and educational buildings. In 2016, Yousef al horr et al [2], reviewed the scientific literature of office buildings with the aim of establishing the complex relationships between IEQ parameters and the health and welfare of the occupants. The results determined that it is important to monitor the performance of the building and the occupant during their operations in order to identify comfort and welfare needs that can be incorporated into the design processes.…”

A key factor for achieving healthy environments in residential buildings is the provision of high indoor environmental quality (IEQ) with respect to the acceptance by its occupants, based on levels of the physical parameters which contribute to IEQ. This research focuses on defining the comfort standards of indoor environments of urban dwellings in the city of Cuenca-Ecuador. It takes into account factors such as temperature, air quality, and natural lightning through a mixed method of quantitative and qualitative measurements. Results determined the following values: a comfort temperature (T n ) of 20.12 • C (with ranges from 16.62 • C to 23.62 • C for an acceptance of 80% and from 17.62 • C to 22.62 • C for an acceptance of 90%), a relative humidity between 40-65%, a maximum CO 2 concentration of 614.25 ppm, a day light factor of ≥5 for the social area and ≥4 for the bedroom, and a minimum illumination level of 300 lux. With these results, it was observed that the comfort levels of temperature, CO 2 concentration, and lighting accepted by local users differ from the standards established in local and international regulations. The determined data constitutes a methodological basis for carrying out similar processes in other localities.
