In 2009, the architect Sergei Tchoban, a passionate drawer himself and collector of historical architectural drawings, founded the Tchoban Foundation. The foundation aims to promote training in the classical drawing for up-and-coming talents and to open the exciting world of architectural drawing up to a wider public. The Museum for Architectural Drawing, which opened in 2013, constitutes a unique location in which the foundation can realise its objectives.
The museum is housed in a distinctive new building, the four storeys of which are stacked on top of one another like building blocks. The storeys are projected and recessed, which makes for an extraordinary silhouette and a recessed glass storey on top completes the construction. The magnified fragments of architectural sketches incorporated into the coloured concrete of the façade as a relief are another highly effective detail and, far from being confined to the museum exterior, the sophisticated design continues on the inside too. An important aspect of this is the lighting concept, the key element of which is a light line. Lines of light cover the walls of the stairwell, are incorporated into the banisters on the landings, flank the entrance and form the sole light source in the exhibition areas.
As well making for an impressive design, the light strips in the ceiling close to the walls in the exhibition areas constitute an excellent light engineering solution for illuminating the drawings. The LED light sources used are free of UV light and their luminous flux can be adjusted to the requirements of the changing exhibitions by means of a light control. This ensures stringent conservation requirements are met reliably while creating good visibility conditions for museum visitors at the same time. The rooms are lent a bright and spacious ambience, attained by means of the special light distribution from LED profile luminaires. Selux developed a special solution for this project based on its M family of luminaires. Uninterrupted light lines are integrated into an 80 mm cross section profile, with precisely calculated prismatic blocks installed in front of these as optics. For the exhibition walls, a wall washer optic system generates homogeneous light without any discernible shading, such as might occur with individual spotlights, meaning the exhibits can be freely suspended without the lighting having to be adjusted.
Project-specific LED-profile luminaires by Selux are also used in the museum's foyer. These are integrated as rectangular contours into the high gloss ceiling and fitted with downlight optics. Since the foyer also functions as a library, general lighting with sufficiently high horizontal illuminance at working plane was also required here.
With the Museum for Architectural Drawing, a light solution has been realised which meets the requirements of curators, visitors and museum managers. The lighting concept's strength of design and very low energy consumption with minimal heat load is highly impressive too. Such qualities were also appreciated by a jury of the German Light Design Prize 2015, which awarded the project a prize in the Museums category.
