When do we ventilate the buildings?

Ventilation awareness in buildings

We all spend 100% of our time breathing air. Therefore, the indoor air environment plays a vital role in health, comfort, and productivity. Ventilation is one of the most important engineering controls in offices, schools and other environments. And good ventilation can save energy while improving indoor air quality.

When do we ventilate the buildings?

Provide …

-When we want to create a comfortable, healthy and safe environment for people – in homes, offices, schools, and other environments.

-When we want to improve the productivity of an employee in office buildings and the performance of students in schools.

-When we want to reduce sick time, i.e. sick days at offices and absenteeism in schools.


-When we want to enhance comfort for buildings occupants, i.e. control temperature, humidity and other parameters of the indoor environment.

-When we want to control occupants exposure to air contaminants, i.e. remove or dilute airborne contaminants.

-When we want to ensure energy-efficient and sustainable operation of a building and also regulated costs, i.e. investment, operating and maintenance costs.


-When the outdoor climate is more extreme, for example in cold climates or hot/humid climates.

-When the close proximity creates problems, i.e. to other outdoor conditions surrounding the buildings such as noise from traffic, location near polluting industries or seasonal issues with dust and pollen, etc.

-When we want to avoid heat build-up in more demanding time periods in a year, for example during hot spells at very warm summers.

-When the building envelope is too airtight and sealed, especially true for newly built buildings and/or renovated buildings.

-When we need to maintain specific conditions due to the purpose of a building, i.e. hospitals and laboratories, etc.
