Retrofitting can be defined into two major categories

HVAC System and Controls

​The proper control of an HVAC system (as shown here for an aquatic centre) can supply the air, in a specialised manner, such that there is:

• no condensation  

• lower humidity 60%  

• less chemical input  

• less water evaporation  

• less smell of chlorine  

• less maintenance
