Air Quality and the Built Environment, 2nd Edition

Dear Colleagues,

Air quality across indoor and outdoor environments plays a fundamental role in shaping human health, well-being, and urban sustainability. As people spend most of their time indoors, buildings serve not only as passive receptors of outdoor air pollution but also as dynamic systems where pollutants are generated, transported, transformed, and removed. Meanwhile, urbanization, climate change, and evolving building technologies are intensifying the interactions among outdoor pollution, indoor air quality, building operation, and human activities, leading to complex exposure patterns and environmental feedbacks.

Air quality in the built environment is governed by multi-scale and multi-physics processes involving pollutant emissions, ventilation, air cleaning, building design, and occupant behavior. Outdoor pollutants penetrate indoor spaces through infiltration and ventilation, while indoor-generated contaminants are released back into the urban atmosphere, forming a bidirectional exchange between indoor and outdoor environments. Understanding these coupled mechanisms is essential for developing integrated strategies that improve public health, enhance comfort, reduce energy consumption, and support low-carbon development.

This Topic aims to gather cutting-edge research that advances the measurement, modeling, assessment, and control of integrated air quality across indoor and outdoor environments. We particularly encourage interdisciplinary contributions that bridge building science, environmental engineering, atmospheric science, public health, urban planning, and data science, fostering holistic solutions for healthy, energy-efficient, and climate-resilient built environments.

We encourage submissions on topics including (but not limited to) the following: (i) sources, transport, and transformation of air pollutants across indoor and outdoor environments; (ii) advanced sensing, monitoring, and data fusion techniques; (iii) coupled indoor–outdoor modeling and exposure assessment; (iv) innovative ventilation, air purification, and intelligent control strategies; and (v) human–environment interactions and health impacts under urbanization and climate change.
