Abstract

Lighting design for museum and exhibition today sets itself the objective of creating a balance between the natural light and the emphasis lighting, focused on given objects on display. For a long time artificial luminaries were used, without any actual study of lighting effect on the artworks or on the viewers. Lighting design today wants to create a perfect balance between natural light coming through windows and skylights, and artificial light, in order to set a comprehensive design plan. I discussed a thesis concerning the lighting design in the reuse of a historical museum, Fondazione Magnani Rocca in Traversetolo, Parma, whose exhibition rooms have to be re-arranged, because of inappropriate lighting levels, so the plan requires suitable lighting technology project, which could be adapted readily to new arrangements also in order to reduce drastically artificial lighting, creating a shading system that allow diffuse light and block direct sunlight. This is the reason that has led to definition of self-supporting, movable, modular opal-glass panels, to be displayed in front of windows and independent of the walls of the historical building. Panels are molded using a lighting calculation software, which allows to evaluate all parameters (considering the most suitable form, inclination, size and complex morphology of glass panels) including artificial and natural lighting effects on 3D surface, displaying different solutions. The software estimates luminance of surfaces, the correct quantity of lighting, according to different hours of the day and season, to assure proper lighting levels for each room (about 200 lux in case of exhibits susceptible to light damage). The presence of panels allows the exact amount of natural light to filter through curved glass panels, as well as the daylight that penetrates from the windows is screened using opal glass. Curved glass panels can be also backlit, with a diversified artificial lighting system, hidden in the back of glass so the floodlights can be fitted in a flexible way, to adjust lux level in the room, completing the illusion that there is much more daylight in the space than is actually present. Artificial lighting control system will read the external lighting conditions, by timing or occupancy sensors in order not to exceed 200 lux, providing for gentle transitions between different lighting states. The renovation lighting design project wants to elaborate a scheme which follows a standard procedure for each room, to capture natural incoming light, spreading it trough curve panels, to enhance exhibited works in the best way possible. The project wants to create a flexible apparatus, with an architectural dynamic lighting technology, by modeling suitable surface, that allows natural indirect light coming in to enlighten exhibition rooms, whereas the presence of curved glass panels grants the diffusion both of artificial and natural lighting when required.
