Dear Colleagues,

People spend a significant amount of their time daily in their workplaces. New indoor environments are now being created in modern buildings as a result of international trends in urban design, residential, commercial and office building design, and reduced construction costs, following new standards, new construction materials and equipment and energy efficiency strategies (for lighting, heating, cooling, ventilation, etc.). Thus, the indoor environment quality (IEQ) is important for occupants’ health and comfort, and is determined by a set of parameters such as temperature, humidity, indoor air quality (IAQ)/air pollution, noise, lighting and ventilation conditions. Improving the well-being of and providing healthy, comfortable conditions for building occupants will become a very important issue in the coming years.

To achieve not only acceptable but also high-quality IAQ and IEQ levels in indoor environments, additional work should be carried out. Hygiene and IAQ with high health safety levels will be of priority after the experience of the COVID-19 pandemic in all types of indoor environments. An increasing concern about the IAQ will be raised not only in office buildings but also in residences due to the widespread implementation of teleworking. It should be noted that air renewal and high-performance ventilation will be demanded, and this will affect occupants’ perceptions of comfort and health. Beyond residences, offices, commercial or public buildings, other indoor environments, especially indoor microenvironments with occupants belonging to vulnerable groups (children, elderly, sick people), such as homes, schools, nursing homes, etc., should be investigated.

Therefore, this Special Issue invites research including, but not limited to, the following areas:

• Indoor air pollution monitoring/modeling;
• Ventilation/infiltration/air flow monitoring/modeling;
• Ventilation system/building design;
• Ventilation versus IAQ and indoor biological agents;
• Ventilation to combat COVID-19, investigations using natural or mechanical systems/usage of air purifiers, etc.;
• IAQ/IEQ comfort/health impact assessment.

If you are interested in this topic, please feel free to contact me, and I look forward to receiving your submissions soon!

Manuscript Submission Information

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. Applied Sciences 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 2300 CHF (Swiss Francs).
