inomhus

Inomhus, a Swedish term meaning indoors, refers to spaces and activities inside a building rather than outside. In everyday usage the term is used to describe the indoor environment and conditions within homes, workplaces, schools, and public buildings.

It encompasses the indoor climate, including temperature, humidity, air quality, ventilation, lighting, acoustics, and ergonomics. The goal is to provide a comfortable, healthy, and energy-efficient environment for occupants.

Ventilation exchanges air with the outdoors to control pollutants, moisture, and CO2 levels. Poor indoor air quality can result from emissions from building materials, furnishings, or activities; common indicators include elevated CO2, particulate matter, and dampness that can lead to mold.

Building design, construction, and operation influence the inomhus environment. Standards and guidelines for indoor air quality and thermal comfort are provided by national and international bodies, and many jurisdictions require ventilation and filtration practices as part of building codes and energy standards.

Optimal inomhus conditions support health, comfort, and productivity, reduce absenteeism, and mitigate sick building syndrome. Occupant behavior, such as opening windows or adjusting thermostats, affects the indoor environment.
