Our mission is to completely regenerate the existing building making it adequate to the new housing needs, however without upsetting the existing urban fabric. Seismic adaptation, sustainability and renewable energies are the basis of the design choices. These were taken to obtain housing with 3 classes with more than seismic resistance and with a classroom Energetics A+ with almost zero emissions.
This result is obtained through the high degree of thermal insulation of the external cladding envelope, the use of efficient technologies for air conditioning and the use of sources renewable with consequent environmental protection, ensuring high internal comfort; the result is a considerable saving on energy consumption and therefore economic for the management of the single house.
SEISMIC IMPROVEMENT OF THE STRUCTURE
The building will undergo some substantial changes both in form, with the construction of large balconies and terraces, and in the structure. The latter will be integrated and improved by three seismic classes. The site conversions that contribute to this improvement are the construction of reinforced plaster, the demolition of the walls of the third floor and the reconstruction of the same with high-performance blocks and the reconstruction of the roof.
COVERAGE AND TERRACES
The roofing of the top floor and the stairwell is flat with a non-usable terrace. All terraces and balconies will be waterproofed in accordance with the best construction techniques, including waterproofing elastic mortar. The gutters and down spouts for the collection of rainwater from the terraces and balconies will be made with fire-painted aluminum pipes and will run along the facade.
FINISHING OF THE FLAPS WITH COAT INSULATION
The entire facade of the building will be covered with the "external coat" system. The wall will be thermally and acoustically insulated by means of rock wool panels of adequate thickness to guarantee the required energy performance, These are applied on the external side of the wall facing and fixed to it by gluing and mechanical anchoring with special plugs. The insulating panels will be protected on the external side by a layer of reinforced plaster with alkali-resistant mineral fiber mesh and by a surface finishing and painting treatment.
The system developed by Knauf ® used for the construction of partitions offers a valid alternative to traditional materials, as well as to solid masonry construction systems. It is able to face the most extreme climatic situations, both indoors and outdoors. And allows to optimize the thermal performance of the building, reducing energy costs even over 30%. The dry layered technology also lends itself to acting as a solution with regards to the aspects relating to acoustic insulation. The coated gypsum plates fixed to the profiles act as opposing masses and inside the air gap acts as a "spring" absorbing noise. A high-performance sound-absorbing material is inserted into the gap created between the metal frames to increase the insulation power. The internal partitions will be made with Knauf W112 partition or similar with soundproofing power characteristics higher than those required by the standards between one apartment and another. The wall is made up, in its essential elements, of a single frame with galvanized steel profiles; coating on both sides of the frame made with a double layer of Knauf sheets, the first GKB and the second Diamant type with high density and mechanical resistance; a double layer of 70 mm Knauf mineral wool insulating mat will be inserted in the gap between the uprights. The bathroom wall that will house the GEBERIT cistern will be made with Knauf W115 + 1 partition with sound insulation characteristics significantly higher than the minimum required by the standards. The wall is made up, in its essential elements, of a double frame with galvanized steel profiles; the external covering on both sides of the frame will be made with a double layer of Knauf sheets. The first GKB and the second Diamant type with high density and mechanical resistance; a single layer of Knauf GKB sheets will be installed on the inner side of the framework. And a double layer of Knauf mineral wool insulation mat 60 mm each will be inserted in the gap between the uprights.
WORKS IN PETRA
Windows, French windows and external wall covers will have a threshold in light-colored travertine stone with a stuccoed and smooth finish, 3 cm thick, with a drainer overhanging 2 or 3 cm with respect to the facing of the wall; the finish of the visible ribs will be straight and beveled. The travertine plinths, as well as the thresholds and the frames of the door and windows, will be restored as they are now, naturally replacing those deteriorated by time and / or which are in poor condition.
EXTERNAL AND INTERNAL WINDOWS
The fixtures will comply with the standards for thermal and acoustic insulation, made of white dyed PVC with KOMMERLING ELEGANCE 70 profile. This profile combined with double glazing allows to reach the highest required standards in terms of energy saving. All windows and French windows will be equipped with iron shutters treated with anti-rust and powder painting. The internal doors of GIO.MA. DOORS white, mod. Katia or similar, will have dimensions 80cm x 210cm or 70cm x 210cm, with a laminated fir wood frame with a section of 40mm x 100mm, covered with cpl foil glued with polyurethane glues and a satin gray handle. The panel made with perimeter frame in laminated fir wood with a reinforcement at the height of the lock. The internal honeycomb honeycomb structure on both sides is covered with a white 4 mm mdf panel and then veneered with real cpl laminate glued with polyurethane glues. Alternatively, the customer can choose the door color from the Gio.Ma Porte catalog, quoted separately based on type and model. The armored entrance door is equipped with a European cylinder, a draft excluder on the floor. And an internal covering panel of the same essence and finish as the internal doors.
