Since it's only used for three weeks for an annual sporting event, the prefabricated Lake Rotsee Refuge has to be protected from the elements for the remainder of the year. Designed by AFGH Architekten, the three story prefabricated tower features retractable sliding shutters that help to achieve this goal, while also contributing to the structure's energy efficiency while it is in use.
Floated on concrete pilings and connected to the lakeshore by a bridge, Lake Rotsee Refuge is the first building to be used for a future rowing club that is expected to be complete by 2016. In the meantime, its sentimental qualities as a natural, timber structure hovering silently above this pristine lake environment serves as an identity marker for the team.
The entire tower, which rests on a concrete foundation, is constructed out of timber. Windows provide ventilation and natural light, while the shutters allow control over solar gain. When not in use, which is most of the time, the shutters protect the structure and also prevents the possibility that birds will strike the reflective glass windows.
