The building sector is considered strategic to reach new scenarios for a low-carbon society. Beside this awareness, in the current trend there is not a real change to achieve targets set in terms of emissions containment defined by international agreements. Through an econometric model based on Choice Experiments, the present study aims to understand the individuals’ perceptions towards energy retrofit...

The inflow into aquifers of transition metals leached from muck disposed in quarries is a process that requires a detailed analysis in the framework of the environmental impact studies of dump sites. It is important to thoroughly examine the risks of potential contamination of pre-existing groundwater wells and, more in general, to assess the risk of qualitative deterioration of nearby shallow aquifers....

The proposal of a simplified hybrid Thermo-Hydro-Mechanical model to investigate poroelastic and thermoelastic stresses induced due to water injection and the different parameters affecting their evolution is presented. The operating mode of the numerical model is starting with a set of implicit fractures, with different adjustable random orientations, then an elastic continuum medium is built, and shear...

Geothermal Energy, being a clean and sustainable source of energy, is gaining importance worldwide due to various reasons. Geothermal power can be generated throughout the year on twenty four hour basis as it’s not much dependent on ambient temperature and weather conditions. Recently there is an increased interest in exploitation of low enthalpy geothermal resources for other applications such as geothermal space heating...

The management of health and safety at work is represented by the set of preventive and protective measures to minimize the exposure of workers to risks that may cause the onset of diseases or increase the number of accidents.

Data on occupational accidents...

Innovative tools are necessary to obtain the optimal operating conditions of the ventilation systems in a reasonable lapse of time and accurately. This can be achieved both with appropriate numerical approaches to the full domain as the model order reduction techniques and with the domain decompositions methods as the multi-scale physical decomposition technique. The reduced order mode techniques such...

The original implant map (OI) of Italian Cadaster was first made out of topographical measurements. These maps have never been used for public consultation, but they are the most accurate ones. The publicly accessible maps are named “visure maps” (VM) and were obtained from the original implant maps and consistently updated. However, these maps have suffered many deformations due to continuous...

The tunnel Piscopio I is a twin-tube tunnel, 750 m long, included in the works of the Maxilotto 2 DG21/04 of the new highway SS 106 Jonica (Calabria, Southern Italy). During the excavation of the Piscopio I tunnel, several lacks in the Geological Model of Reference emerged. Above all, the discovery of a complex landslide along the left hydrographic side of the Alessi River, which interfered with the tunnel...

The adoption of reinforced embankments for rockfall and landslide protection purposes is an effective intervention for the reduction of risk and damages to civil facilities. These earth structures are manufactured with layers of compacted soil alternated with geosynthetics (e.g. geogrids and geotextiles) that are anchored to the outer quarterdeck frame or wrapped around it. This paper discusses the results...

The paper provides an overview of the several scientific and technical issues and challenges to be addressed for underground storage of carbon dioxide, hydrogen and mixtures of hydrogen and natural gas. The experience gained on underground energy systems and materials is complemented by new competences to adequately respond to the new needs raised by transition from fossil fuels to renewables. The experimental...

Avalanches are natural events that can have consequences such as silvicultural losses, infrastructural damages, fatalities. In this paper, the attention is given to glide avalanches starting by a glide crack, a tensile crack that propagates at the crown – the upper release limit – due to the internal stress variation. However, the presence of a glide crack does not always give rise to a glide avalanche....
