A simulation study of ventilation and indoor gaseous pollutant transport under different window/door opening behaviors

The window/door opening behavior of occupants is a very important factor in determining the airflows and ventilation conditions in buildings, on which indoor pollutant concentration and transport are highly dependent. A two-room residence model was simulated in this study to analyze the airflow characteristics and pollutant transport under different window/door opening behaviors. Airflows were unidirectional and the residence could not be treated as a well-mixed zone when there were no temperature differences.

IEA EBC Annex 68 - Indoor Air Quality Design and Control in Low Energy Residential Buildings – Setting the Metrics

This paper presents the initial reflections in the frame of Subtask 1 – Setting the Metrics of the IEA EBC Annex 68 – Indoor Air Quality Design and Control in Low Energy Residential Buildings. The first step of IEA Annex 68 aims at summarizing the current knowledge on target pollutants for residential buildings and at evaluating indoor air quality (IAQ), i.e. how to define indices that provide useful information allowing to achieve low risks for health in indoor spaces, and how to enable the comparison of solutions for achieving high IAQ taking into account energy efficiency.

Opening windows almost always reduces the risk of contamination with SARS-CoV-2. But it is important to be aware of low outdoor air temperatures that could affect the comfort of occupants and exacerbate related health problems. 

Although close contact transmission is the dominant transmission route, long-range airborne transmission through small size infected aerosols plays an important role in spreading COVID-19 in indoor spaces. Ventilation is air exchange between inside and outside; it dilutes the concentration of contaminants, and hence helps to control aerosol-based cross-infection risk of COVID-19.

AIVC Ventilation Information Paper #42: The Concept for Substituting Ventilation by Gas Phase Air Cleaning

AIVC's Ventilation Information Paper no 42: The Concept for Substituting Ventilation by Gas Phase Air Cleaning has just been released! The paper discusses and evaluates the pros and cons by partly substituting required ventilation by gas phase air cleaning.

VIP 42: The Concept for Substituting Ventilation by Gas Phase Air Cleaning

Worldwide, there is an increasing number of publications related to air cleaning and sales of gas phase air cleaning products. This puts a demand for verifying the influence of using air cleaning on indoor air quality, comfort, well-being and health. It is thus important to learn whether air cleaning can supplement ventilation with respect to improving air quality i.e. whether it can partly substitute the ventilation rates required by standards.
