waste. Very practical, renovation just needs the application of the most directly effective measures. The study clearly demonstrates that it was possible to double the existing frames from the inside (instead of replacing them with triple glazing). The character of the façade is well maintained, creating a buffer volume between the windows that keeps the heat in during the winter months and uses sunscreens in the summertime which cannot be seen from street level. The approach for dwellings (passive) is the opposite: contrast and visibility, rather than modesty and adaptability. The housing plans provide for a double orientation. Mainly open to the south towards the rue de la Loi, the rooms all face the interior. Playing with the technical constraints, such as the presence of the panel points and elevator shafts, the rooms are designed as lightweight steel structures, part of which are prefabricated, with the rest assembled on-site. The
breathable cover is banded with wood, including movable flaps clearly visible to the south. From a technical standpoint, the extra heat and hot water are provided by the renovated office facility.. ■
