“…For example, indoor concentrations of fine particulate matter do not correlate closely with outdoor concentrations [5]. Elevated concentrations of ozone (O 3 ) in the outdoor air do not typically penetrate indoor environments, but can enter dwellings more effectively by mechanical and open windows [6].…”

During the 20th century, air pollution control technologies grew at an amazingly rapid rate. Air quality in much of the industrialized world greatly improved as the efficiencies of these technologies improved. This continued improvement in pollution control has more recently been complemented with measures to prevent the emission of air pollutants. The previous, exclusive focus on treatment requires systems thinking. This review provides a framework for this Special Issue of Sustainability by describing the new tools that are needed to support this new, broader focus, including life cycle assessments, exposure models, and sustainable design.

“…Similarly, I/O ratios for PM 2.5 were found to be higher at the trafficked site than the residential site [153]. A comparative study by Lai et al [154] found that the I/O ratio of ozone for using natural ventilation is significantly higher than for using mechanical ventilation with filtrations. Moreover, Rivas et al [155] reported that the indoor levels of traffic sourced pollutants, such as NO 2 , equivalent black carbon (EBC), ultrafine particles (UFP) and stibium (Sb), are very similar to those recorded outdoors.…”

a b s t r a c tMany buildings in urban areas are more or less naturally ventilated. A good understanding of the current status and issues of indoor environmental quality (IEQ) in naturally ventilated urban buildings and the association with urban microclimate is fundamental for improving their IEQ. This paper reviews past studies on (a) the microclimate in urban street canyons, (b) the potential influence of such microclimate on IEQ of nearby naturally ventilated buildings, and (c) the real-life IEQ status in these buildings. The review focuses mainly on studies conducted by on-site measurements. The microclimate in urban street canyons is characterized by low wind speed, high surface temperature difference, high pollutant concentration, and high noise level. Insufficient ventilation rates and excessive penetration of outdoor pollutants are two key risks involved in naturally ventilated urban buildings. Existing knowledge suggests that reasonable urban planning and careful building envelope design are the primary methods to ensure acceptable IEQ and maximize the utilization of natural ventilation. However, quantitative studies of both microclimate in street canyons and IEQ in buildings are still highly insufficient in many aspects, which make cross comparison and influencing factors analysis currently impossible. Based on the limitations of previous studies and the current issues of naturally ventilated urban buildings, suggestions are made for future studies to better understand and improve IEQ in naturally ventilated urban buildings.

“…Related penetration research is usually carried out in two ways: field measurement and laboratory simulation. Field experiments are always conducted in real buildings such as school classrooms, dormitories, and offices (Chao et al, 2003;Chatoutsidou et al, 2015;Cong et al, 2018;Hu et al, 2018;Hussein, 2017;Lai et al, 2015;Liu et al, 2018;Zhao et al, 2019;Wang et al, 2019;Chen and Zhao, 2017), while a test chamber or a building brick is usually used as the object to simulate the indoor or outdoor environment in laboratory simulations (Chen and Zhao, 2017;Lai and Nazaroff, 2000;Li et al, 2017;Liu and Nazaroff, 2001;Lv et al, 2018;Wang et al, 2020). The difference between laboratory simulation and field testing is a greater control of the conditions in a laboratory setting.…”
