“…The computational fluid dynamics (CFD) technique shows size-dependent (PM 10 /PM 2.5 /PM 1 ) PM removal behavior. In addition, the increased ventilation rate is effective in the human bioeffluents such as CO 2 (Chen and Hsiao 2015;Emmerich 2006;Wargocki et al 2000). The mechanical ventilation air conditioning (MVAC) system causes reduction in particulate matter concentrations by forced exhaust and opened windows, together with the filtration process through the air filter in the building environment (Hanley et al 1994;Riley et al 2002;Wang et al 2006).…”

Particulate matter (PM) in buildings are mostly sourced from the transport of outdoor particles through a heating, ventilation, and air conditioning (HVAC) system and generation of particle within the building itself. We investigated the concentrations and characteristic of indoor and outdoor particles and airborne bacteria concentrations across four floors of a building located in a high-traffic area. In all the floors we studied (first, second, fifth, and eighth), the average concentrations of particles less than 10 μm (PM10) in winter for were higher than those in summer. On average, a seasonal variation in the PM10 level was found for the first, fifth, and eighth floors, such that higher values occurred in the winter season, compared to the summer season. In addition, in winter, the indoor concentrations of PM10 on the first, fifth, and eighth floors were higher than those of the outdoor PM10. The maximum level of airborne bacteria concentration was found in a fifth floor office, which held a private academy school consisting of many students. Results indicated that the airborne bacteria remained at their highest concentration throughout the weekday period and varied by students' activity. The correlation coefficient (R (2)) and slope of linear approximation for the concentrations of particulate matter were used to evaluate the relationship between the indoor and outdoor particulate matter. These results can be used to predict both the indoor particle levels and the risk of personal exposure to airborne bacteria.

“…Kajtár and Herczeg (2012) found that the diastolic blood pressure and heart rate was increased by a high (near 300 ppm) CO 2 concentration. Chen and Hsiao (2015) found that the increase in CO 2 concentration led to respiratory change and increased the respiration rate and body temperature. Apte, Fisk, and Daisey (2000) announced that the increase in CO 2 concentration also increased their study subjects' respiration and metabolism.…”

“…Recent technological advances enabled the measurement of the realtime monitoring data on physiological responses. As the physiological responses to the IEQ condition can indicate the maintenance of homeostasis against external stimuli, in this study, such responses were used as the occupant health index (Zhang, Wargocki, and Lian 2016;Kajtár and Herczeg 2012;Chen and Hsiao 2015;Cheng et al 1995;Budd and Warhaft 1966;Sun and Zhu 2013). The previous studies that used building occupants' physiological responses were also divided into three categories: (i) those that dealt with building occupants' physiological responses to the indoor air pollutant factors; (ii) those that dealt with building occupants' physiological responses to the indoor climate factors; and (iii) those that dealt with building occupants' physiological responses to their own activities (refer to Table 2).…”

“…Traditional assessments of the values of buildings and real estate were carried out through economic or environmental assessments (Kim, Hong, and Koo 2012;Hong et al 2015;Koo, Hong, and Park 2016;Jeong et al 2018;Kim et al 2015aKim et al , 2015bKoo et al 2017;Jeong et al 2017;Ji et al 2016;Hong et al 2016;Park et al 2016;Kim et al 2016bKim et al , 2016aHong et al 2013). Due to the environmental issues, however, reducing a building's energy consumption and providing an improved IEQ are the two major issues that building professionals the world over are dealing with (Aglan, 2003;Hamilton M, Rackes A, Gurian PL, Waring MS 2016;Park and Yoon 2011;Varjo et al 2015;Cheong et al 2003;Ravindu et al 2015;Lan et al 2011;Xue, Mak, and Ai 2016;Jaggs and Palmer 2000;Zhang, Wargocki, and Lian 2016;Kajtár and Herczeg 2012;Chen and Hsiao 2015;Cheng et al 1995;Budd and Warhaft 1966;Sun and Zhu 2013;Mehler et al 2009;Haapalainen et al 2010;Carayon 1993;Fisk and Rosenfeld 1997;Worrell et al 2003). First, according to International Energy Outlook 2016, the energy consumed by the building sector in the year 2016 accounted for about 20% of the total delivered energy consumed worldwide (Government Publications Office 2016).…”

The buildings' indoor condition called "indoor environmental quality (IEQ)" has become a major goal, all IEQ elements must be maintained within a certain range for the comfort and health of the occupants. To achieve this goal, the previous studies focused on building occupants' responses based on their activities and the changes in IEQ. Few studies, however, have comprehensively analyzed the above and reflected it in building design and operation. The study of this concept can be expressed as "human-building interaction management." This approach is a paradigm for the healthy, sustainable, and simultaneous management of people, IEQ, and buildings. This study conducted an in-depth literature review on the abovementioned studies. In addition, it ultimately proposed an intelligent planning unit (IPU), a new approach that can be used as a tool to apply the above human-building interaction concept to the practical design concept focusing on the planning phase. The IPU theory is designed to meet the customer expectations for the various objectives of a complex built environment. Eventually, it is expected that the proposed IPU concept will promote the spread of good health and environment-friendly buildings.
