Wallenmahd Elementary School, Dornbirn (AT)

The new concept for this school and gymnasium is largely based on the original plans. The two-story annex to the back of the school building, the janitor’s building and the annex to the gymnasium where equipment is stored had to be demolished. The janitor’s building was replaced by a new, one-story structure with a barrier-free entrance, day care center and the library. This annex was planned as an exposed concrete structure with interior insulation. The building envelope of the existing school building was renovated while at the same time keeping the character of the building intact.
A glazed corridor and a shed roof connect the school and the gymnasium. The shed roof defines a shielded break area. A suspended acoustic ceiling reduces the noise in the classrooms. In the corridor area, this accommodates conduits and air ducts for controlled ventilation. The staircase was upgraded with a fire-resistant glass enclosure to provide an emergency exit.
An elevator was installed next to the staircase to guarantee a barrier-free access for all. A thermal insulation optimizes the building envelope. The windows and glazing made of triple-pane insulated glass offer a high G-value, and are largely equipped with exterior blinds with light guidance for shading. The building services engineering controls the degree of shading.
