Special Issue Information
Dear Colleagues,
Currently people spend approximately 90% of their time indoors, where the concentrations of some pollutants are often 2 to 5 times higher than ourdoor concentrations. Numerious studies have demonstated the importance of indoor air quality to human health, and addressed the importance of ventilation to indoor air quality. As an outcome, national and international standards have been developed to design ventilation to achieve acceptable indoor air quality. The present standards are based on the assumption of perfect air mixing; as a result, ventilation requirement is generally simplified to be the requirement for the amount of outdoor air, i.e. ventilation rate. However, in practice, a number of factors, such as ventilation design (the number and distribution of air inlets and outlets), occupancy condition, and indoor spatial configuration, can make a great difference to ventilation impact on indoor air quality. Sometimes, local ventilation rate may be much smaller than the ventilation rate designed for the whole room, resulting in high local concentrations of air pollutants. The advanced methods and technologies to detect and locate indoor air quality issues at a dynamic mode, then quantify and satisfy the requierement for additional ventilation, are a great charllenge in the field.
We also lack of knowledge to define the ventilation requirement to prevent aerosol transmission of respiratory diseases. The emergence of SARS-CoV-2 viruses, especially the most prevalent Delta variant which is extremetly fast-spreading and highly transmissible, presents a new and great challenge in indoor air quality. There is an urgent need for the revolutionary knowledge and technologies to develop the effective ventilation strategies against the spread of respiratory infectious diseases.
Ventilation efficiency is highly related to energy consumption in a building. A feasible ventilation strategy for a building must balance the requirements for air quality and energy-use. Moreover, during the pandamic, the requirement on social distance and the resulted reduction in indoor occupancy make ventilation efficiency more critic to a sustainable building.
At this point, we would like to invite all authors whose research concerns ventilation and indoor air quality in sustainable buildings. The main schope of this special issue is to highlight the ventilation impacts on indoor air quality in sustainable buildings, and the advanced ventilation technologies, including but not limited to:
- Original ventilation method, technology, and unit;
- Quantification of ventilation requirement for aerosol infection control
- New sensoring methodologies and tehcnologies to identify indoor air quality problem
- Ventilation design for suistanable building regarding indoor air quailtiy
- Case study of ventilation impact on indoor air quality

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Sustainability is an international peer-reviewed open access semimonthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
Benefits of Publishing in a Special Issue
- Ease of navigation: Grouping papers by topic helps scholars navigate broad scope journals more efficiently.
- Greater discoverability: Special Issues support the reach and impact of scientific research. Articles in Special Issues are more discoverable and cited more frequently.
