The Multipurpose unit is an innovative emergency shelter developed inside the European project FP7 EU Project ‘S(P)EEDKITS- Rapid deployable kits as seeds for self-recovery and is the result of a successful collaboration between the design research group of Politecnico di Milano, our specialist team and the SRU (Shelter Research Unit from IFRC) experts. The Multipurpose Unit has been conceived for being removed or reused for other purposes later. It measures 48 m2 (6x8 m) and is designed to shelter between 10-12 people. This product can be adapted to different uses: first emergency shelter, medical ward, school, offices and so forth; moreover is fast-erecting and contains all the essential accessories in the basic kit package (shade net and groundsheet). Thanks to the vertical walls it facilitates the connections between units (both on the front and along the sides), allowing the creation of bigger spaces and camp infrastructures. The frame is composed by aluminium poles connected with steel rabbet joints, which are the same but rotate to facilitate the building procedures. The joints functions also as shade net antennas allowing the elimination of additional framework to support the layer; in this way the shade net can be integrated in the basic kit. Also the poles are all the same except for the hip of the roof, where an extension is provided. The fabric is hung from inside the structure in order to ease the assembling/dismantle operations. The Multipurpose Unit can be used in all climate types guaranteeing the users comfort in different conditions. The shelter has been tested to withstand snow load up to 30 kg/m2. For the application in hot climate, the attention is pointed on good ventilation and shading system.
