The project establishes a new bioclimatic school complex integrated into the urban fabric, characterised by a compact building form and flexible learning spaces. The building incorporates an integrated passive ventilation strategy: the use of wind chimneys generates a stack effect which, combined with cross-ventilation, ensures natural air exchange and reduces summer cooling loads without relying on energy-intensive mechanical systems. The technological approach is based on circular economy principles, employing low-embodied-energy materials sourced from the local rice production supply chain. The timber structure is complemented by infill panels made of compressed rice straw, lime-and-rice-husk plasters, and lightweight screeds, providing thermal time lag and natural hygrothermal regulation. The integration of green roofs and photovoltaic panels further enhances the building’s energy performance, reducing CO₂ emissions and operating costs throughout its entire life cycle.
Il progetto definisce un nuovo comparto scolastico bioclimatico integrato nel tessuto urbano, caratterizzato da un volume compatto e spazi didattici flessibili. L’edificio adotta una strategia di ventilazione passiva integrata: l’impiego di "camini del vento" attiva la stack ventilation che, combinata alla ventilazione trasversale, garantisce il ricambio d’aria naturale e l’abbattimento dei carichi termici estivi senza ricorso a sistemi meccanici energivori.Il profilo tecnologico è improntato all'economia circolare attraverso l’uso di materiali a bassa energia incorporata derivanti dalla filiera risicola locale. La struttura in legno è completata da tamponamenti in paglia di riso pressata, intonaci in calce e lolla e massetti alleggeriti, assicurando sfasamento termico e regolazione igrometrica naturale. L’integrazione di coperture verdi e pannelli fotovoltaici ottimizza l’efficienza del manufatto, riducendo le emissioni di $CO_2$ e i costi operativi lungo l'intero ciclo di vita dell'opera.

Abstract
The project establishes a new bioclimatic school complex integrated into the urban fabric, characterised by a compact building form and flexible learning spaces. The building incorporates an integrated passive ventilation strategy: the use of wind chimneys generates a stack effect which, combined with cross-ventilation, ensures natural air exchange and reduces summer cooling loads without relying on energy-intensive mechanical systems. The technological approach is based on circular economy principles, employing low-embodied-energy materials sourced from the local rice production supply chain. The timber structure is complemented by infill panels made of compressed rice straw, lime-and-rice-husk plasters, and lightweight screeds, providing thermal time lag and natural hygrothermal regulation. The integration of green roofs and photovoltaic panels further enhances the building’s energy performance, reducing CO₂ emissions and operating costs throughout its entire life cycle.| File | Dimensione | Formato | |
