system. It also allows us to control the supply and extracting points. The heat recovery is achieved through a heat exchanger which cools and/or dehumidified the warm fresh air with the cool outgoing air. Figure 9 below shows a basic layout of a simple extract-andsupply system with heat recovery.

The fresh air also needs to be filtered in order to avoid pollutants being transferred in the building, compromising the supply air quality. In addition to the heat recovery system, a control system is considered, which monitors the CO2 levels inside the building and regulates the flow of fresh air accordingly. This control system could save energy when certain areas of the building are less occupied or not being used.

Hence, the requirements for the ventilation system are:  Extract and supply system  Heat recovery  Filtering  Control system adjusting air flow rate according to CO2 levels
