	The perforated cladding on the outside of the building is heated by the [[solar radiation]] from the Sun. Because of this, ~~the~~ solar walls are generally very dark or black ~~in colour to reduce~~ the amount of [[radiation]] that is reflected from this wall. The system must be hooked up to the ~~buildings~~ HVAC system, as ventilation fans are used to create negative [[pressure]] in the air channel between the walls. This negative pressure pulls ~~the~~ air warmed by the Sun into the building.<ref name="RE1"/> Cool air is expelled from inside the building into the air channel through a vent located at the bottom of the wall. Once this air is warmed it begins to rise and is then fed into the HVAC system through a vent located at the top of the wall. The warm air is supplied to and distributed in the building via the HVAC system intakes.<ref name=Article1> H. Chan. S. Riffat and J.
