    INTESA (INTegrazione ed elevata Efficienza con sistemi a Secco per l’Abitare, Integration and high efficiency with drywall technology for building envelopes) is an innovative solu-tion of a drywall façade embedding electrical, plumbing and HVAC systems, especially de-signed for residential needs. The INTESA system is usable either for new and retrofit design and is competitive with the traditional wet technology made of clay bricks or blocks. Since the early stage of the project, an integrated approach has been the key element to design the wall system in order to obtain an easy and efficient way of assembling, a perfect integration of the plants, as well as high thermal and acoustical performances. In-field INTESA perfor-mances were tested in laboratory and in a real case study through the construction of a proto-type building located in Calliano d’Asti, near Turin, where the following acoustical parame-ters were measured: the apparent sound reduction index (R’), the standardized sound level difference of a façade (D2m,nT) and the vibration sound reduction index (Kij), a quantity relat-ed to the vibrational power transmission over a junction between structural elements

    INTESA System: A New High-performance and Highly Integrated Drywall Façade

    INTESA is an innovative vertical envelope for residential, industrial and service tertiary buildings. It is a drywall façade system with high thermal and acoustic properties, embedding electrical and plumbing systems. The system was developed over two years by a multidisciplinary team, which involved researchers, manufacturers and consultants. An integrated approach has been the key element to design and prototype an innovative double cavity drywall façade, composed by plasterboard layers and blown-in cellulose flakes, with and without a thin layer of Phase Change Material. Thermal and acoustical properties have been optimized through laboratory measurements and simulations and later tested in a prototype building
