The contribution presents the results of field research aimed at assessing the effects of the Phlaegrean Bradyseism phenomena on a building system located in the historic centre of Pozzuoli (Italy). The study falls within the scope of building fa & ccedil;ade vulnerability analyses conducted by the authors to support the Public Administration in managing bradyseismic emergencies. Considering that the seismic-deformation phenomena connected to Bradyseism affect the performance and integrity of fa & ccedil;ade components, the research focused on studying its impact on the technical elements within the Technological Unit Classes of Load-bearing Structure, Enclosure, and External Partition, which directly project onto the external environment and collectively constitute the Building Envelope. The methodology for impact assessment was developed by correlating data acquired from a monitoring system installed on the fa & ccedil;ade of a surveyed building with characteristic parameters related to seismic events and soil deformations in a specific reference period. The analyses conducted excluded any significant impact of these seismic-deformation forcings on the building's Load-bearing Structure, both in terms of displacements and damage. On the other hand, significant impacts were found on the technical elements of the building envelope, which, due to their lower resistance and ductility, represent a constant hazard for the exposed urban system's safety, configuring a Building Risk scenario.

The construction industry plays a significant role in shaping our environment and economy. However, it also substantially impacts the environment, including the depletion of natural resources, increased energy consumption, and waste generation. The green building trend has recently gained significant attention in recent years to mitigate the negative impacts of the building industry, focusing on sustainable materials and practices. One of the primary materials used in this field is clay brick, which leads to soil depletion over time. In this context, this study explores the potential of sawdust waste as a partial replacement for clay in brick production, aiming to reduce the depletion of natural resources while enhancing the properties and performance of the produced bricks. The study consists of two main phases: experimental and simulation. In the experimental phase, clay brick samples were produced by adding sawdust at different ratios (1%, 2%, 4%, 8%, and 10% of the raw weight), and various physical and mechanical properties of the produced samples were tested to ensure their suitability for construction use. Also, the thermal properties of the proposed brick were measured to investigate the effect of sawdust addition on brick thermal insulation. Consequently, thermal conductivity and specific heat were measured. In the simulation phase, DesignBuilder software (version 7.0.2) was used to investigate the impact of the proposed material on building envelope's performance and heat gain reduction. All experimental and simulation results were compared with the traditional clay brick measurements, which reveal a significant improvement in brick properties and performance with an increase in comprehensive strength of up to 192.3% and a reduction in energy consumption reaching 11.27%. The study results showed significant improvement in the properties and performance of the produced bricks, indicating the potential of using sawdust waste as a sustainable material for green buildings.
