1 - ARCHITECTURE The plot is crossed by hiking path from the current 280 that comes from the present Fanton bivouac until the fork of Jau Tana. Hiking path means a path without technical difficulty. It's the kind of path most popular, accounting for 75% of the routes of the entire trail network of the region. All the trails are marked CAI along their route with a white-red code like a wire. The type of trail is of two types: vertical or horizontal. The first is generally represented by a table in the form of an arrow with red tip and tail white-red. It is used to indicate the direction of / and target location of the path and the time needed to reach the indicative / and for an average hiker. On the tail, in the white space, shows the number of the path. You can find it at the start of the route and at more important intersections. The second is represented on natural elements such as rocks or tree trunks. It's used to indicate the continuity of the path; is placed in the immediate vicinity of the junctions and every 2-300 meters if the path is clear, otherwise at closer range, taking into account the environmental characteristics. Our intervention strategy will focus in proposing an architectural element that acts as natural as well as refuge.
2 - SUSTAINABILITY We believe that a project can be defined as sustainable when it has the ability to self-renew and when able to transmit and generate comfort. The orography of the area has led to the study taking into account the volume of solar radiation and wind. We made a volume that could get the maximum energy efficiency and could also give feelings of pleasure and relaxation to hikers in the moment of rest. We have choosed to use sustainable materials and natural, such as wood, wood fiber, plywood and steel; these materials are durable, require little maintenance work and respect the environment. As regards the structure of the campfire, the initial design strategy was in the direction of technology useing X-LAM, but after accurate calculations we have seen that would not been the most economical solution and not even the most simple from the manufacturing point of view. Therefore, for reasons of economic sustainability, we opted for a frame structure by wood, with lighter weight in order to allow the assembly away from the site and its transportation by helicopter at once, avoiding excessive costs and limiting environmental pollution. Was also possible to achieve an architectural object self-sufficient from an energy standpoint, through the exploitation of solar radiation by means of a photovoltaic system that can generate enough power for the illumination of the internal environment and for the operation of a webcam for the control of the bivouac remotely.
