Conference Paper
The effectiveness of care provided by EMTs is directly linked to the ability to ensure a controlled, coordinated, and safe patient flow through the post, especially in case of MCIs or disease outbreak. Currently, there are neither frameworks nor tools to analyze such flow that is often visualized on paper using arrows or simply connected to the car...
Article
Building maintenance needs in public buildings depend on occupant activities and presence. Research should understand how different types of occupant density patterns can be used to forecast the likelihood of specific kinds of maintenance requests. This research adopts a data-driven approach to evaluate experimental-based correlations between maint...

Full-text available
In hot-humid climates, porous external surfaces of the buildings with high water sorption capabilities could contribute to the surface temperatures reduction through the release of latent heat by evaporative cooling. On the other hand, compact and low permeable finishing materials could have mechanical and durability benefits respect to the underly...
Article
Floods are among the most destructive sudden-onset disasters affecting worldwide communities and society. Pedestrians can be forced to evacuate affected areas thus being exposed to multiple risks. Outdoor built environment flood risks analyses should be performed through rapid, easy, and sustainable tools to speed up and support risk assessment and...
Article
In the building management process, the collection of end-users' maintenance requests is a rich source of information to evaluate occupants' satisfaction and building systems. Computerized Maintenance Management Systems typically collect non-standardized data, difficult to be analyzed. Text mining methodologies can help to extract information from...
Chapter
When sudden-onset disasters occur in the urban Built Environment (BE), people must quickly leave the dangerous areas to reach safety. Floods in urban BEs surely represent a critical emergency, especially considering users who cannot evacuate upstairs, such as those placed outdoor. Management strategies focused on the evacuation planning could incre...
Article
In the aftermath of catastrophic events, lightweight construction systems are often used to build temporary emergency architectures. However, if suitable environmental control systems are not present, as may occur in post-disaster scenarios, these buildings provide poor indoor thermal conditions, especially in hot climates, which may jeopardize the...

Touristic cities will suffer from COVID-19 emergency because of its economic impact on their communities. The first emergency phases involved a wide closure of such areas to support “social distancing” measures (i.e. travels limitation; lockdown of (over)crowd-prone activities). In the second phase, individual’s risk-mitigation strategies (facial m...

Urban Built Environments (UBE) are increasingly prone to SLow-Onset Disasters (SLODs) such as air pollution and heatwaves. The effectiveness of sustainable risk-mitigation solutions for the exposed individuals’ health should be defined by considering the effective scenarios in which emergency conditions can appear. Combining environmental (includin...

University buildings are one of the most relevant closed environments in which the COVID-19 event clearly pointed out stakeholders' needs toward safety issues, especially because of the possibility of day-to-day presences of the same users (i.e. students, teachers) and overcrowding causing long-lasting contacts with possible "infectors". While wait...
Article
Urban floods are becoming more and more intense and frequent allover the world. Extreme events are the main triggering factors of such floods, and merit attention for what concerns the urban planning and emergency strategies. Numerical models aimed at investigating the optimal paths for evacuees escaping a flooded urban environment may be used by l...

Preprint
Restarting public buildings activities in the "second phase" of COVID-19 emergency should be supported by operational measures to avoid a second virus spreading. Buildings hosting the continuous presence of the same users and significant overcrowd conditions over space/time (e.g. large offices, universities) are critical scenarios due to the prolon...

Internal insulation is a typical renovation solution in historic buildings with valuable façades. However, it entails moisture-related risks, which affect the durability and life-cycle environmental performance. In this context, the EU project RIBuild developed a risk assessment method for both hygrothermal and life-cycle performance of internal in...
Chapter
The exploitation of Building Heritage generally leads to sustainability issues in terms of environmental preservation and tourist enjoyment. When these requirements are not jointly respected, occupancy issues can provoke degradation phenomena on indoor environment (i.e., building materials and surfaces with artistic and historical value) or conditi...
Chapter
Gli ambienti ipogei di valore culturale spesso possono ospitare artefatti, come graffiti, pitture e rilievi. Questi ambienti sono caratterizzati da condizioni microclimatiche aprticolari a causa dell'isolamento con l'ambiente esterno e spesso da dimensione ridotte. La combinazione di questi due elementi richiede una strategia ad hoc che garantisca...

Article
In the light of the regulations on buildings energy performance, the designers face the need to choose among alternative design solutions, having to assess their effectiveness according to several -sometimes conflicting- points of view, such as the energy saving, the indoor comfort, the environmental and economic impact. This paper reports the resu...
Chapter
The tourism exploitation of architectural heritage generally leads to preservation issues. Human presences inside indoor spaces indirectly provoke sudden and high variation of environmental parameters: such hygrothermal fluctuations are responsible for hygroscopic materials decay. Our research defines a "mart" low-impact system for improving surfac...
