Building Environment (IEQ)


The indoor environment quality (IEQ) accounts for the variables the occupants learn, work and play in. The better the conditions, the happier and healthier it is for the occupants.

This building improves the indoor environment quality by improving the following conditions:


Ventilation improves the indoor environment quality by providing fresh, clean air for the benefits of the occupants. Lack of ventilation and fresh air leaves people feeling tired and unproductive. Indoor pollutants (called Volatile Organic Compounds or VOC’s which come from artificial products such as plastics and vinyls) contribute to the occupants feeling unwell.

So critical to occupants health and wellbeing are the presence, or lack thereof, of Carbon Dioxide and VOC’s that is present in the building.

This building monitors both the CO2 levels and the VOC concentration of the indoor environment and increases the ventilation when required. Of course, full natural ventilation would be the ideal solution to avoid the build up of these two gases for most of the time, but this means little control over the indoor temperature – another indoor environment variable.

So it becomes a balancing act, maintaining healthy air as well as keeping the temperature comfortable. On the roof are ventilators that extract the warm expired air from the training floor to allow the fresh air to come in at low level. At full speed these ventilators can deliver XXX Litres of air per second. These of course can be shut off to prevent the loss of warm air in winter.
