Ventilation 

The provision of ventilation in all types of buildings is a pre-requisite in order to comply with BUILDING REGULATIONS and promote a fresh, stable indoor environment. Depending on the application of a building the level and type of ventilation required will vary. 
Examples of ventilation needs may be: 
 
Occupational 
Odour dilution 
Combustion ventilation 
Smoke extraction 
 
Ventilation can be achieved in many different ways utilizing natural characteristics of a building or by mechanical assistance. 
 
With the correct design this can be combined with other systems, such as air conditioning, to further enhance to use of energy in a building and reduce the impact on the global environment.
