Les fenêtres à Lyon entre 1650 et 1900, des dispositifs techniques qui transforment la ville

Abstract : The window is a major element of a dwelling building. With the door, it is its main exchange and interaction device, particularly for light. It also materializes the technical possibilities of the moment and constitutes a social interface between interior private space and exterior public and street space. It is also a major climatic interface. Studying the way windows were made and lived as such an interface is not so much interesting as it deals with decors, but in how it evolved through time. Windows were more frequently modified than buildings, when adapted to new techniques and fashions. This evolution reveals also a profound anthropological transformation or urban space seen as continuity from the bedroom to the street landscape, as it also concerned the street climatic equipment, often subject to regulations: roofs, varied protections against light and rain, light dispensation. At Lyons, five main periods can be identified: - Before 1700: The window, generally a sliding one, is separated by a stone cross and adorned with oiled paper, which allows for only a feeble light inside and is not a very efficient thermal interface. - 18th century: glass, still prized, becomes widespread, making easier ocular exchange between interior and exterior. In the mean time, heating is easier for high classes. - 19th century: the window is made of complementary elements: large glassed panes letting a lot of light pass, exterior slatted blinds protecting from the sun, interior shutters for cold. Coal heating becomes available for nearly everybody. - From late 19th century: The windows is if desired the only interface between body and exterior, all intermediary climatic system ("alcoves" partitioning around the bed, interior shutters, slatted blinds...) being suppressed. Only exterior metallic blinds remain, for light and privacy. - From late 20th century: energy is more expensive, which leads to narrower windows and sophisticated technical solutions (double glazing, etc.). Many older windows are replaced. Heritage dealing with windows is very difficult, as they have been generally modified several times since the building's construction.
