are equipped with a mechanical supply and exhaust ventilation system that mini-
mises energy losses through heat recovery. The required heating energy is provided
by a two-stage heat pump system. A large groundwater heat pump in the nearby
lido that the entire campus area is supplied with heat through a cold local heating
network with minimal losses. A second heat pump in the building itself provides
the necessary temperature level for the underfloor heating and hot water for the
showers. The operating energy for this system is generated by a photovoltaic system
of approximately 250 square metres on the building’s roof. The project budget was
modest, so costly cladding for the technical installations was deliberately avoided.
Only in the circulation areas, suspended ceilings made of clay panels were installed
to create a visually calm space. This contributes to a simple aesthetic and facilitates
maintenance and revision of the systems. The solid wood and clay surfaces of the
building were left unclad after the completion of the shell construction phase. Elec-
trical cables and outlets were integrated into the cross-laminated timber walls during
the construction phase, so no subsequent chiselling or plastering was required. The
rammed earth wall also allows for the invisible installation of empty conduits and
outlets, which were placed directly into the formwork and incorporated during con-
struction. This forward-thinking planning reduces future labour costs and subtly inte-
grates the technical components into the natural aesthetics of the materials used.
The result is a compelling contrast between archaic clay and wood surfaces and
modern technical installations.
