The transformations created about the design activity by the several challenges started by the economies crisis, climate change and environmental emergencies, together with the impact of the Web and ICT on social and productive systems, highlight many critical issues, but also significant prospects for updating concerning places, forms, contents and operating methods of “making architecture”, at all levels and scales.

In the built heritage context, BIM has shown difficulties in representing and managing the large and complex knowledge related to non-geometrical aspects of the heritage. Within this scope, this paper focuses on a domain-specific semantic-enrichment of BIM methodology, aimed at fulfilling semantic representation requirements of built heritage through Semantic Web technologies. To develop this semantic-enriched BIM approach, this research relies on the integration of a BIM environment with a knowledge base created through information ontologies.

The present contribution deals with an ongoing Italian research which includes several steps and it is approaching to its final stage. The main goal is analysing and testing the feasibility of municipal waste reuse for designing building envelopes for Near Zero Energy Buildings (NZEB), so as to contribute to the decreasing demand for energy and improve eco-friendly waste management in urban areas.

The relationship between users and the built environment represents a fundamental aspect of health. The factors that define the properties linked to health and well-being are increasingly becoming part of building design. In these terms, building information modelling (BIM) and BIM-based performance simulation take on a priority role. Among the key features for the design of Healthy Buildings, indoor air quality (IAQ) plays a central role. There are numerous indoor pollutants with significant health effects; volatile organic compounds (VOCs) are to be mentioned among these.

Gli studi condotti in questi ultimi decenni hanno documentato un progressivo aumento in assoluto delle sostanze
inquinanti nell’aria indoor. Tra le esigenze di benessere, si è ormai consolidata l’importanza di igiene
e salute degli utenti, dato che la popolazione trascorre in media oltre il 90% del proprio tempo all’interno degli
spazi costruiti, essendo quindi particolarmente esposti a presenza di inquinamento indoor e scarsa qualità
dell’aria a fianco di criticità termoigrometriche, che nell’insieme possono avere importanti impatti sulla salute.

The development and the prospect of future cultural heritage should certainly be confronted with the development of new technologies applied to the arts which, from a legal point of view, implies mainly three important aspects.1. Copyrights for software: this seems to be the least interesting for the jurists as many aspects have already been addressed and solved, and therefore on will just quickly list some of them.

Nell’ambito delle nuove applicazioni digitali dedicate allo sviluppo del progetto architettonico, appare ultimamente imperativo l’uso del BIM Building Information Modeling, applicativo dedicato all’organizzazione e relazione dei dati componenti il progetto e, nella sua declinazione, è interessante la specializzazione nel sistema HBIM (Historical Building Information Modeling).

Il modello progettuale di un sistema costruttivo aperto si basa sul concetto di sistema edilizio come integrazione di molteplici soluzioni tipologiche e di prodotti disponibili sul mercato. Attraverso una matrice di integrabilità tra le componenti tecniche, i progetti di costruzione possono essere sviluppati adottando di volta in volta le specifiche soluzioni tecniche a catalogo predisposte all’interno della gamma di prodotti adottati dal sistema.

Il volume raccoglie i contributi dei ricercatori, dei professionisti e degli operatori del settore, sullo stato della ricerca nell’ambito del 3D Modeling &BIM. È interessante verificare come, analizzando le “Keywords” presenti nei contributi, siano presenti quelle più comuni e fondanti il tema, come i termini BIM, HBIM, 3Dmodeling, VR, AR, Interoperabilità.

The study on the functioning of HVAC systems and hydraulic circuits in buildings has highlighted the energy limits of a static management of the parameters that regulate them. The main recurring problems regard inadequate maintenance, failures, losses and malfunctions. With the development of new digital methodologies on the management of data flows (BIM and IoT) it has been demonstrated how the dynamic analysis of the sys-tems functioning parameters can lead to wide margins of improvement in terms of ener-gy use and containment of energy costs.
