The new residential tower will have 1,700 square meters of vegetation, distributed on the floors so that the flora and forna will change the colours of the building as the seasons change. The vegetation will absorb 14 tons of CO2 and produce 9 tons of oxygen per year, like a 10 thousand square meters forest. With 2,770 square meters of photovoltaic panels, the tower will be able to self-produce 65 percent of its energy needs. The building includes structural parts in wood that will decrease its carbon footprint. The project will redesign the separating ‘wall’ on Via Melchiorre Gioia by creating a new hub for events, shows and exhibitions, with meeting and wellness areas and a biodiverse greenhouse space as an extension of the Biblioteca degli Alberi that will be a dedicated laboratory to provide an immersive, educational, interactive and innovative experience among various plant species. Pirelli 39 will be the first Italian project fully measurable according to ESG criteria (LEED Platinum, WELL Gold, WiredScore certifications etc.).
