Why Do We Need To Learn About Healthy Buildings?
To a human-being the walls of a building can be regarded as a third skin (the first is our own skin, the second is our clothing). Most buildings do not breathe like our natural skin and unfortunately in the USA this has been shown to lead to a build-up in radioactive radon gas and reduce the benefits of passive solar energy in spring and autumn. If a building is to be sealed (which most are) then it needs to be well ventilated to remove unhealthy pollutants.
Many buildings contain hazardous materials or substances without the owner's knowledge. Freshly constructed cement homes have high levels of moisture, homes built in the 60's contain asbestos cement which is known to be carcinogenic and old piping systems are frequently painted with lead paints. In addition to the household disinfectants, fly sprays, paints, varnishes, and other fumes released from a large range of furnishings and commodities are of no benefit to the occupant's health.

- Explain the affect of space perceptions may have on human health, in a visited interior workplace.
- Evaluate the psychological impact of the interior environment in two distinctly different offices, upon the people who work in each of those offices.
What Affects the Inside Environment?
The climate of an internal living space can be determined by things such as:
• installations and furnishings
• noise and acoustics
• lighting and colours
• radiation, avoiding disturbed areas
• radioactivity
• space, form and proportion
• physiology and psychology of living and working
• city planning with biological, ecological and sociological aspects.
How Important is Ventilation?
Ventilation in a building serves many purposes but mainly serves to remove undesirable components in the air such as carbon dioxide, smoke, vapours etc and to allow the renewal of fresh air. In addition to this ventilation can also help control temperature, humidity and velocity of the air.
When provisioning ventilation there are actors that need to be considered:
• Energy conservation, especially if the air being removed has previously been heated. Losing this heat could dramatically increase energy consumption.
• Noise;
• Fire control
• Volume of air required
• Air movement and distribution to different areas of the structure
• Temperature changes
• Humidity changes
• Control
• Filtration
What Else is Important to Understand?
This is a complex area of study, which mankind is still only starting to learn about; but nevertheless very important to human health and wellbeing.
