Coronavirus spread is more serious in urban metropolitan cities compared to rural areas. It is observed from the data on the infection rate available in the various sources that the cold and dry conditions accelerate the spread of coronavirus. In the present work, the existing theory of respiratory droplet drying is used to propose the mechanism of virus spread under various climates and the indoor environment conditions which plays a greater role in the virus spread. This concept is assessed using four major parameters such as population density, climate severity, the volume of indoor spaces, and air-conditioning usage which affect the infection spread and mortality using the data available for various states of India. Further, it is analysed using the data from various states in India along with the respective climatic conditions. It is found that under some indoor scenarios, the coronaviruses present in the respiratory droplets become active due to size reduction that occurs both in sessile and airborne droplet nuclei causing an increase in the spread. Understanding this mechanism will be very useful to take the necessary steps to reduce the rate of transmission by initiating corrective measures and maintaining the required conditions in the indoor built environment.

Infectious microbes can spread rapidly from fomites (contaminated surfaces) via hand touch, with prolonged residence time on surfaces increasing transmission risk by extending exposure periods and/or involving more susceptible individuals. Existing studies have focused on decreasing microbial contamination, but not on the need for rapid removal from surface systems. This study introduces residence time as the time that a microbe spends within the surface system.

In the context of population ageing, the age-friendliness of neighborhood built environment (NBE) is increasingly recognized as essential for enabling ageing in place. However, while much research has focused on the impact of NBE on the physical health of older adults, its relationship with mental health (MH) remains underexplored, especially the pathways through which NBE indicators influence MH. This study measured NBE using ten indicators across three categories: daily travel (including barrier-free travel, elevator, rest seat, diversion of pedestrian and vehicle, road surface and public toilet), healthcare services (including public canteen and elderly care), and social participation (including outdoor fitness space and indoor activity space).

The school built environment is closely related to children's health, and research on this topic is increasing. However, bibliometric analyses seeking to provide a comprehensive understanding of the research landscape and key themes in the field are lacking. This study comprehensively explored the global trends and research hotspots on the associations between school built environment and children's health.

Air-source heat pumps are popular in buildings to provide cooling and heating. However, how the air discharged by air-source heat pump outdoor units affects the dispersion of air pollutants in urban street canyons remains poorly understood. This study used coupled simulations to examine the effects that air-source heat pump outdoor units had on vehicle-induced indoor and outdoor air pollution in an urban street canyon and how these effects varied based on the arrangement of outdoor units or the presence of building envelope components (e.
