Moving towards a Robust Definition for a "Healthy" Indoor Microbiome

Area of Science:

• Environmental Health
• Microbiology
• Building Science

Background:

• Buildings significantly impact human health through microbial exposures.
• A clear definition of a
• healthy
• indoor microbiome is currently lacking.
• Understanding indoor microbiomes is vital for vulnerable populations, including children with asthma.

Purpose of the Study:

• To define the characteristics of a healthy indoor microbiome.
• To explore the link between building design, occupant behavior, and indoor microbial communities.
• To inform the development of assessment methods for indoor microbiomes.

Main Methods:

• Literature review on indoor microbiomes and building design.
• Analysis of existing data on microbial exposure and health outcomes.
• Conceptual framework development for a healthy indoor microbiome.

Main Results:

• Current understanding of indoor microbiomes is insufficient for defining
• healthy
• environments.
• Building design and occupant behavior are key modulators of indoor microbial ecosystems.
• There is a need for standardized methods to assess indoor microbiomes.

Conclusions:

• A robust definition of a healthy indoor microbiome is essential for future building design.
• Developing assessment tools will empower occupants and professionals to improve indoor environments.
• This research highlights the interdisciplinary approach needed to create healthier indoor spaces.
