Timber construction, passive house standards and multistorey atrium
Convinced of the importance of designing schools, Dietrich | Untertrifaller Architects successfully developed a harmonious overall solution incorporating three important concepts: Timber construction, passive house standards and a multistorey atrium.
The new secondary school of Klaus was built to replace the existing school, and designed with highest possible energy efficiency and lowest possible budget in mind. After a record construction time of only 18 months, the school opened in 2003. In a second step (2013-2014), a multifunctional hall replaced the no longer appropriate sports facilities. Both buildings now create a protected square, from which the school, gymnasium and library are accessible.
The building – constructed entirely in wood – fulfills Vorarlberg passive-house guidelines and consumes less than 15 kWh/m² total energy per year. Compared to conventional solid construction, the costs for this innovative and sustainable project were only 3 % higher, while the energy costs have been reduced by 70 %, compared to the old school building.
The spatial concept of the L-shaped building includes three main functions: school, gymnasium and library. The long front facade orients to the street and houses the library, recess areas and the covered entrance. The classrooms and administration are located in an adjacent wing, creating an exterior courtyard to the northeast. A glazed transverse-bar connects the school with the gymnasium tract and offers acoustic protection for the classrooms and courtyard.
A wide three-storey atrium is located in the center, lit from above, rhythmically interrupted by the foot bridges providing access to the classrooms. The classrooms are bright and on the east side they benefit from the sky light of the central building section. Exterior solar shading prevents glare and generation of heat. To maintain sufficient view a low ribbon glazing positioned toward the inside is placed just below the tall window sills and permits a good view while providing shading. The developed areas of the central section are divided into small spaces between the foot bridges by sky lights and tall lockers that provide screening, thus transforming the long corridor into a lively meeting place during recess.
The building unit housing the classrooms is equipped with a controlled ventilation system that generates heating or cooling as required. An additional heating register facilitates temperature control in each room. In summer and winter the air is pre-heated or pre-cooled, respectively, to 18° Celsius via Earth Coupling. Heat is generated by a calorific value gas tank. A number of other measures ensure high energy efficiency, which is further optimized by the facility manager via a special computer software. As a successful pilot project the school building received several awards in the categories of architecture and energy efficiency.
