The building aims to provide a dwelling space that protects people from the sandstorm and for people to have social activities even during the sandstorm period. The project aims to change people’s lifestyles in terms of social life with sandstorms and the local hot weather. The main construction method is rammed earth. The thickness and the material used for the rammed earth structure contain large thermal mass which insulates the heat from sunlight. The challenge of the project is to apply curvature and tilting angles on rammed earth wall. The curvature will create soft shadow and the tilting angle will create sharp shadow. The criteria are whether the residence is welling to enjoy the social life in the project instead of staying indoor during sandstorms. In the technical aspect, the criteria are about whether passive cooling can replace the use of air conditioner completely, and whether its structure and experience can promote the atmosphere for social activities. The outcome of the project is a condo that provides social communication space during sandstorms and provides a more environmentally friendly living method.
