The sustainable residential complex GIOIA 22 is situated at the heart of the Porta Nuova district of Milan and, upon completion, will meet 65% of its annual energy requirements using renewable energy sources.
GIOIA 22, in Milan, Italy, is setting new benchmarks in terms of sustainability. The 120 m tall tower at the heart of the Porta Nuova district will meet 65% of its annual energy requirements using renewable energy sources. The 30-storey tall building will provide enough space for approximately 2,700 people, 350 parking spaces and 13 lifts. PERI provided support during the construction process for this project, using a combination of tailor-made formwork and climbing solutions. GIOIA 22 is the first building of its size in Italy to meet the NZEB standard (nearly zero energy consumption building). A characteristic feature of the building is its folded shape which is of ecological significance in addition to being aesthetically pleasing. Advanced technology and structural planning will allow the exterior and interior spaces to be used in an innovative manner. For example, the 225,000 integrated photovoltaic panels will generate enough electricity to supply the equivalent of approximately 300 households. Only two years after the founda36

Project-specific combination of system formwork The building consists of a main core with 26 floors and a secondary core with 13 floors. A special feature is that, from the second floor upwards, the tower starts to fold in on itself so that the slabs become wider with each passing floor. A project-specific combination of different system formwork was required to create the unusual shape of the building. Moreover, the construction work had to be completed as quickly and efficiently as possible, in order to meet tight deadlines. For these reasons, the decision was made to combine the SKYDECK Slab Formwork with an additional RCS P System Solution to realise the slabs from the second floor upwards. Systematic erection sequences and lightweight system components made it possible to complete an entire floor in a week.
