Large-Eddy Simulations of Wind-Driven Cross Ventilation, Part 2: Comparison of Ventilation Performance Under Different Ventilation Configurations

open access: yesFrontiers in Built Environment, 2022
Natural ventilation can contribute to a sustainable and healthy built environment, but the flow can be highly dependent on the ventilation configuration and the outdoor turbulent wind conditions.

Public toilets with insufficient ventilation present high cross infection risk [PDF]

open access: yesScientific Reports, 2021
Due to insufficient ventilation, public toilets present high risks for cross-infection. The study investigated 61 public toilets to identify the causes and locations of biological contaminated sources. Airborne and surface bacterial contamination, carbon

Evaluating cross contamination on a shared ventilator [PDF]

open access: yesEmergency Medicine Journal, 2020
BackgroundDisasters have the potential to cause critical shortages of life-saving equipment. It has been postulated that during patient surge, multiple individuals could be maintained on a single ventilator. This was supported by a previous trial that showed one ventilator could support four sheep.

Study of the low moving efficiency of bioaerosol with insufficient air inflow and exhaust in the public toilets [PDF]

open access: yesE3S Web of Conferences, 2023
Due to insufficient ventilation, public toilets have become incubators for cross-infection during the pandemic. WHO has proposed an approach to improve indoor ventilation, including ventilation in isolated spaces like toilets, by applying the 10L/s ...

Passive Night Cooling Potential in Office Buildings in Continental and Mediterranean Climate Zone in Croatia

open access: yesBuildings, 2022
The envelope is one of the most important driving factors in the energy efficiency of buildings. Typical for office and commercial buildings, curtain wall facades allow solar heat gains to be used during the winter but can lead to difficulties in ...
