The concept was realized considering, first and foremost, efficiency and sustainability; it consists of two macro project areas. A master plan of the entire lot and an architectural focus on the main building, called precisely “Architectural focus.” The sustainability strategies included in the concept were inspired by LEED® protocol guidelines. In particular, the Architectural Focus building was designed to achieve LEED® certification, LEED® Gold level. The open spaces were designed to provide the building’s occupants with the opportunity to relate to the outdoors to improve their well-being and productivity. For the green areas, a selection of plant species was made: native, adapted and drought-resistant plants that were selected in order to reduce the need for irrigation, and the use of chemical fertilizers and pesticides. In addition, the landscape was designed to minimize effects on microclimates by reducing the heat island effect.
The concept emphasized the goal of maintaining the natural water cycle, reducing runoff volume and improving water quality, this by replicating the natural hydrology and water balance of the site. Stormwater was designed to be treated as a resource rather than a waste product, encouraging its infiltration, filtration, storage, and reuse.
In addition, a phytodepuration system, that is, a natural wastewater purification system consisting of an impermeable pond with a gravel bottom and vegetated by aquatic plants, has been provided. From the treatment, purified water complying with legal limits is obtained, without sludge production. Purification occurs through the combined action of gravel substrate, plants, wastewater and microorganisms.
Al fine di ottimizzare la manutenzione e le operazioni legate all’energia e all’efficienza degli impianti è stato progettato un polo tecnologico dedicato al solo Focus Architettonico, con apparecchiature termiche, frigorifere ed elettriche ad alta efficienza. Questo polo tecnologico è stato progettato per l’alloggio di pompe di calore condensate ad aria, apparecchiature di trigenerazione per la produzione contemporanea di acqua calda e refrigerata ed elettricità, pompe di calore, torri di raffreddamento, sottostazioni elettriche, quadri elettrici, sistemi antincendio. Gli spazi all’interno dell’hub sono stati ottimizzati per ottenere facile accesso e manutenzione.
Il comfort termico negli spazi occupati è stato concepito conforme alla classe B secondo ISO 7730: 2005. La temperatura e la velocità dell’aria sono state analizzate con l’analisi CFD, mentre il comfort luminoso è stato analizzato con il calcolo della luce diurna.
In the concept of the architectural focus, the following LEED® strategies were involved: high efficiency of HVAC equipment, low LCGWP (life-cycle global warming potential), control of local thermal comfort, lighting comfort due to LED lamps with CRI> 80 (color rendering index), renewable energy production, mechanical ventilation, reduced potable water consumption due to efficient drain and flow equipment, and finally metering devices for water consumption and energy consumption.
In terms of materials, the concept focused on the selection of building materials with high pre and post-consumer recycled content and low emissions and VOC content; materials were selected by maximizing regional sourcing characteristics. Finally, dedicated areas were provided for the collection of waste during operation; particularly for paper, glass, plastic, batteries, and electronic waste.
