Dealing with (affected by) ventilation

1. The importance of good ventilation - The main reasons for ventilation are all about people ⁠— for us and about us.

2. Who and how is affected by ventilation? - Interaction with ventilation, degree of control, effects of ventilation

3. Who is dealing with ventilation? - Building occupants, owners, manufacturer...

Scientific research shows that ventilation is not only about 'window opening' or 'fresh air from the outside', but it rather deals with the notion of creating 'a good indoor environment'.

Who needs ventilation?

Simple answer is everybody - from animals to people. Ventilation is important for everyone - from the basic physiological need to 

Where the ventilation is needed?

Cars, airplanes, and ships also frequently have ventilation passageways and systems that help control air quality and circulation. And one of the most dependent on ventilation are the closed structures located in spaces without the natural occurance of air (and other substances).   submarines and of course spaceships.

Who deals with ventilation?

Ventilation is all about air - heating/cooling it and changing it and get it clean.

Occupants interactions with ventilation

Occupant impact on ventilation, i.e. how occupants react to and/or are affected by the indoor environment

All about occupants´ perception about ventilation and indoor climate in the buildings they live/sleep, work and leisure.

The degree of control

A key consideration is the degree of control that occupants have over the indoor environment. This very much depends on the type of building and on the adequacy of control measures provided.

  • In single homes, the occupant has virtually total access to the various mechanisms available (heating, ventilation controls, window opening etc.).
  • On the other hand, in multi-storey dwellings, offices, shops, public buildings and industrial premises, direct control may not be available to occupants or, if accessible to individual users, they may influence the environment for adjacent occupants. Unless there exist more individual controlled environment - based on the zoning of the spaces/buildings or the demand controlled control systems, etc.

The effects of occupants interaction

Basically, it can be stated what are the effects of occupant interaction on several issues:

  • the influence that occupants have in controlling their environment
  • factors beyond the control of occupants
  • thermal comfort, and or draught
  • health, well-being and productivity
  • energy use and environmental impact

What we all can do, i.e. outdoor air quality control

The steps towards achieving good indoor environment starts with outdoor pollution, source control (via legislation), location of air intakes (design and guidelines), building location (proximity to pollution sources), envelope insulation and airtighness (legislation and guidelines), filtration of particles (i.e. starting with source control + air filters and so on).  And delivering clean supply air.

In essence these steps are primarily within the domain of legislation and requirements imposed on the designer and builder to ensure that the occupant is protected
