Since Riga, Latvia has a distinctive quality of light, the concept of the terminal is to create a dynamic skin by parametric modeling that will respond to the light. Parametrically the skin could be open both horizontally and vertically and three attractor points control the openings. The vertical openings are highest around the middle of the terminal and it decreases as it moves towards the piers and the horizontal openings are the opposite. The extruded skin will help to prevent direct light into the building. Both the Schengen and Non-Schengen sides of the terminal are identical that the entire passenger could enjoy the same experience. The arrivals people are greeted by the grand scale arrival zone and it gives them a friendly welcome.
