Directed to the APPEARANCE FACADE ENTRANCE TO THE BUILDING STAIRWELLS / ELEVATORS 26 Different characteristics of new facade (shapetexture-color) corresponds to different dwellings' types Improvement of housing differentiation; Vertical-horizontal extension/contraction of dwellings; Improvement of performance of existing envelope (like thermal and sound insulation, ventilation, day light and shadings); Improvement of total energy consumptions. Local regulation (in Italy size and number of rooms of social dwellings are subjected to restrictions provided by law); Local regulation with respect to its integration with the surroundings; Structural capacity of the block (in many Italian residential blocks, like Laurentino 38, tenants made inner changes. Alterations they made, like moving of walls and/or big openings, have to be calculated to design the combinations); Technical restrictions if used the tunnel technology (anchorages of extensions restricted to location of walls/floors of the tunnel, and its horizontal tie-rods; better new structures hanged to the tunnel to prevent overloading of existing floors; thickness of new horizontal structures needs to be compatible with existing floors). *** Better appearance if using materials that remind good quality housing (no cheap materials like masonry or plastic) High degrees of differentiation could result in a 'patchwork' at the expense of the appearance; Repetition of the same solution (like shape and material) could replicate initial problems; Short lasting materials shorten 'wow effect' of renovation Improvement of sense of identification with own block and dwelling; New appearance could improve orientation in the neighborhood; The block could function as a landmark Effectiveness of renovation design could be subjected to preferences of people; Relevant transformation of appearance could be used as a window sponsoring the restructuring of the area; Could be used as a selling point Attract different target groups could be difficult even when the appearance substantially change; Relevant transformation of the appearance could be subjected to the approach undertaken by the housing association; In Laurentino38 the concrete panels of the façade were prefabricated in situ. When placed by using a crane they were fixed by means of concrete casting. Cutting the reinforcements to detach the panels might be technically difficult and expensive. 27 Covering with new light colored materials (masonry) If cladding with special technical performances: improvement of quality of existing envelope (like thermal and sound insulation, ventilation, daylight and shadings); Improvement of total energy consumptions. Critical deterioration of the envelope; Local regulation with respect to its integration with the surroundings; * Break of repetitiveness especially when colors and textures are changed; Better appearance if using materials that remind good quality housing (no cheap materials like masonry or plastic) Repetition of the same solution (like shape and material) could replicate initial problems; Lack of integration with the surroundings; Short lasting materials shorten 'wow effect' of renovation Improvement of sense of identification with own block and dwelling; New appearance could improve orientation in the neighborhood; The block could function as a landmark 28 Openings into existing walls Contribute to the differentiation of accessibility; Restrictions due to the tunnel technology if openings into outside walls; 29 Substitute existing walls with glazed surfaces Contribute to the differentiation of accessibility; Restrictions due to the tunnel technology if openings into outside walls; Structural capacity of the block (in many Italian Structural capacity of the block (in many Italian residential blocks, like those in Laurentino 38, tenants residential blocks, like those in Laurentino 38, tenants made inner changes.

Local regulation with respect to its integration with the surroundings; ** Break of repetitiveness; Better appearance if using materials that remind good quality housing (no cheap materials like masonry or plastic) Repetition of the same solution (like shape and material) could replicate initial problems; Lack of integration with the rest of the block; Short lasting materials shorten 'wow effect' of renovation Decrease of sense of anonymity: residents can identify themselves with their own dwelling; Improvement of orientation within the neighborhood by distinguishing single entrances to the block Effectiveness of renovation design could be subjected to preferences of people; Relevant transformation of the appearance could be subjected to the approach undertaken by the housing association; PHYSICAL ASPECTS (technical-functional) APPEARANCE SOCIAL ASPECTS FEASIBILITY S W S W S W S W

Radical solutions might rather be attractive to certain groups as artist-like people that are very important in improving livability of the neighborhood; Effectiveness of renovation design could be subjected to preferences of people; Relevant transformation of appearance could be used as a window sponsoring the restructuring of the area; Relevant transformation of the appearance could be subjected to the approach undertaken by the housing association; 34 Cover with new light colored materials (masonry, wood, green, stones) 35 Add movable shadings If cladding with special technical performances: When the structure supprting the shadings is attached improvement of quality of existing envelope (like thermal outside the block it prevents overheating in summer; and sound insulation, ventilation, daylight and Shading the facade people can regulate themself; shadings); Improvement of total energy consumptions.

Alterations they made, like moving of walls and/or big openings, have to be calculated to design the extension); Local regulation with respect to its integration with the surroundings; ** Break of repetitiveness. Transformation of massiveness and silhouette S W Repetition of the same solution (like shape and material) could replicate initial problems; Short lasting materials shorten 'wow effect' of renovation W If they are attached to a glazed facade wrapping shared spaces (like galleries and terraces) they can stimulate better social cohesion: people would use those spaces because their livability; People might really think it is important that sustainable issues are implemented. Societal awareness. The design should be subjected to preferences of people: architectonic characteristics of the shadings might not be appreciated by residents. Leads to the improvement of the dwelling's quality; Could improve market position of dwellings; No special expertise is required; Renovation works could be very quick; Tenants can stay their dwellings during the works; Relevant transformation of the appearance could be subjected to the approach undertaken by the housing association; Limited energy savings. However, they do not constitute a financial return for the housing association but only for tenants; Energy savings for renovation of existing social housing estates is not compulsory, but it will be in the next future; 'Sustainable renovation' is an investment on the long run; PHYSICAL ASPECTS (technical-functional) APPEARANCE SOCIAL ASPECTS FEASIBILITY S S W S W
