Large buildings are occupied by workers as well as visitors. A visitor could be from other businesses or could be a customer seeking service or products. Examples of such buildings could be a bank, Entertainment centres, Government administration buildings, Large business enterprises, Hospitals, University classrooms, schools   or other educational facilities etc. 

The employees housed in these building produce value for  the organisation which pays the salary for the employees and incur cost of operating the building in terms of energy, utility, safety, Cleaning services, compliance requirements etc.  

It is therefore imperative that all the costs must be optimised for improved productivity. Typically the biggest cost is the salary expense of the employees or the occupants of the building. It is well known that the productivity of a building occupant is highly influenced by his/her perception of the Indoor Environmental Quality (IEQ). IEQ is in turn related to the Indoor Air Quality  (IAQ).

The IAQ tool that has been developed measures building occupants’ perception of the IEQ from a set of questions that can be accessed using a QR code. The tool also deploys a set of sensors in the building to independently monitor IAQ in the building. 

The tool uses these two unrelated datasets and relates occupants’ perception with the measured physical parameters. Using a proprietary algorithm occupants’ perception of the IEQ can be related to the measured physical parameters of IAQ. The conclusions are presented in a dashboard. 

The information in the dashboard can be used to optimise operating parameters of the physical plant of the building to attempt an improvement of the occupants’ perception of the IEQ which in turn would improved the productivity in the building
