Elementary school building of the German School of Athens (GR)
Colourful large louvre blades as design elements
Spatial restructuring, structural addition and visual harmonisation through the façade were among the key objectives of the most recent extension to the German School of Athens (Deutsche Schule Athen). The architect responsible for the design, Alexandra Kalliri, varied the appearance of the façade by offsetting the fine, horizontal structure of the slimline natural timber units against the vertical arrangement of the wide, brightly coloured large louvre blades of the active Schüco Large Louvre Blade System ALB.
Founded in 1896, the German School of Athens is a German international school comprising a kindergarten, an elementary school and a high school which is split into a German and a Greek section. German and Greek teachers at the school teach around 1150 pupils of both nationalities. Following the successful Federal-State Inspection of German Schools Abroad (BLI) in 2013, the German School of Athens was awarded the quality seal of “Excellent German School Abroad”, which currently around 110 of the 140 German international schools are entitled to bear.
Fourth extension since 1988
Before the most recent extension, the existing building of the German School of Athens was characterised by its three different construction phases. During the first phase, the single-storey initial building was constructed (1988); in the second phase, another storey was added (2001); in the third phase, the building was structurally reinforced (2009). Due to the different construction phases, Athens-born architect Alexandra Kalliri was faced with a complex, heterogeneous building as the basis for her design. This resulted in the complicated task of not only creating a new building, but also incorporating the functional and design aspects of the existing structure into a homogeneous school ensemble. The general stylistic specifications of the client and education board, the German School Association of Athens, stipulated contemporary, sustainable and above all environmentally-friendly architecture.
The entrance hall was relocated and enlarged, so that it reflects the new size and increased capacity of the school. It is now directly linked to the schoolyard and to a new multi-purpose space, which also opens out directly onto the schoolyard. Due to the two existing stairwells, the new third floor follows the structure of the storeys below it.
Colourful large louvre blades characterise and structure the façades
The building has an L-shaped floor plan. Each wing has a different colour – blue for the entrance wing, red/orange RAL shades for the vertical wing. The building was designed to be bioclimatic, with the thermally insulated external walls being fitted with a new timber curtain wall throughout, which is divided into storeys by ribbon windows with sun shading louvre blades. The elektromechanically controlled louvre blades manage how much sunlight enters the classrooms – they optimise the amount of natural light and provide effective protection against overheating in the warmer months.
The interplay of colour, materials and structures in the façades has a lively yet orderly effect. The slimline timber panels lend the surfaces a fine horizontal structure; a “micro scale” which, according to the architect, is particularly popular in pre-schools and elementary schools. The wide, vertically arranged sun shading louvre blades form a contrast to this in terms of structure and material and, through the interplay of colours and their movement in relation to the sun, they breathe constant life and variety into the façades.
A ventilation system provides the rooms with fresh air in winter. The lighting in the classrooms is controlled automatically depending on the amount of natural light. In the adjoining rooms (e.g. the toilets), the lighting is controlled by motion sensors.
The outdoor spaces and the building were re-designed to have step-free access throughout. The garden was replanted and equipped with a new play area, where the pupils can have lots of fun between lessons.
Finger-trap protection through individual system programming
When the external sun shading was being designed, a great deal of attention was paid to the range of motion of the individual louvre blades. The most important consideration in this regard was preventative finger-trap protection. It was possible to implement this essential safety function by individually programming the Schüco sun shading control system to ensure that the louvre blade groups never completely close.
Behind the louvre blades and elsewhere in the building, Schüco system technology also provides lighting, visibility and security. The window units are from the Schüco AWS 65 system family and for the doors, single and double-leaf system units from the Schüco ADS 65 HD range were used. Finally, multiple fire-resistant door units from the Schüco ADS 80 FR60 series were used to form fire zones, which offer protection from fire, smoke and heat radiation for 60 minutes in the event of a fire.
On 16 June 2016, the new elementary school building of the German School of Athens was officially opened.
