Overview of the possible causes of SBS and recommendations for improving the internal environment

Included in this chapter are some of the possible causes of SBS and possible ways of eradicating these problems. Problem areas have been identified from research carried out extensively on a worldwide basis. Much research has been carried out to try to prove conclusively the cause of SBS. This unfortunately has not as yet been achieved, with many of the previously held ideas being disproved. Heating and ventilation systems, air quality, noise levels, humidity and temperature will be investigated for their contribution to SBS.
