We based our proposal upon a traditional Chinese courtyard house typology. Each room and function is housed within an individual building volume, which are connected at the corners to remove the need for hallways and excessive circulation space.

The relationship of the house to the sun is critical. In a climate such as Ordos’ which experiences hot summers and cold winters, it is the architectural form which integrates the effects of the sun’s light and heat with the comfort of the occupied spaces. The house controls heat and light through two primary aspects: window placement and the solar chimney.

In the wintertime when the sun is lower and the need for internal heat greater, the windows and skylights, oriented towards the south, west and east, allow sunlight to enter. Passive heating is achieved as the masonry walls and floors absorb the accompanying solar radiation which then is released to heat the spaces.

In the summer, when the sun is higher and thetemperatures greater, it is more important to keep the occupied spaces cool. The deep window sills help to shade the interior spaces from the higher summer sun while still allowing in ambient light. Because heat rises, the solar chimney acts to draw hot air up and away from the occupied spaces, and the hot air is further removed through the operable skylights. Lower, cooler air is then drawn into the space at the occupancy level, further helping to cool the rooms. Furthermore, the masonry walls and floors slow and decrease the transmission of solar radiation into the interior spaces.
