In the light of the recent intentions of the European Union, the issue of decarbonisation has become critically important in the building sector. The coherence between the attention of policy makers towards the issues of decarbonisation and urban regeneration and the higher academic interest can be linked to the current needs of sustainability and the climate objectives . The present review aims to provide a general framework of the state of knowledge on the broad topic, focusing on the investigation of the interrelationships existing between energy retrofit interventions, urban redevelopment and the consequent dynamics of the real estate market. The study has been developed as a systematic analysis of the existing literature on the topic in order to point out the main explored aspects, the geographical contexts, the investigated market segments and the most used methodological approaches. Specifically, 167 papers have been analyzed, whose 44 % investigates the relationship between energy retrofit and real estate market, 39 % explores the link between the urban regeneration and property sector and 17 % points out the effects of dynamics of the real estate market on urban transformation interventions. To summarize some of the most significant data regarding the estimated sample, approximately 75 % of the articles has been published after 2016, around 50 % focuses on the European context, more than half of the papers addresses the residential sector and the majority of the contributions (approximately 70 %) consists of scientific Journal articles. In particular, approximately 50 % explicitly indicates the increase in real estate value resulting from the implementation of an energy retrofit/urban redevelopment intervention. Descending from the above, the review provides a valuable reference to address the subjects involved in building and urban renewal operations towards profitable and effective choices.

Most of the expressions describing fire plumes reported in the literature are known to be based on experiments. Due to different experimental methods, the geometry of the fire sources, fuel types and surrounding conditions, it is difficult to derive a comprehensive picture of a plume with its temperature and velocity fields on the basis of existing theoretical work. Computational Fluid Dynamics (CFD), which is regarded as a practical engineering tool in fire engineering by the experts, is sure to be able to give more details of the plume behavior under various situations. Aerodynamics for thermally-induced plumes will be studied numerically with CFD. Four typical axisymmetric plume equations will be assessed in this paper, and investigations will be useful for fire engineers in designing smoke management systems in an affordable fashion. This is a critical point in implementing engineering performance-based fire code.

This paper discusses a visco-elastoplastic constitutive model to analyze the creep deformability of asphalt concretes at high service temperatures, finalized to improve the interpretation of permanent deformation phenomenon and performance design of road pavements. A three dimensional constitutive visco-elastoplastic model is introduced, in tensor as well as in numerical form. The associated uniaxial model is used to arrange a plastic element in series with the viscoelastic component. The latter is defined by an elastic spring placed in parallel with three Maxwell elements. Three different hardening laws, namely isotropic, kinematic and mixed hardening, are included in the constitutive model to compare the creep deformability. The proposed constitutive model has been calibrated and validated on the basis of uniaxial creep-recovery test results at 40℃. This is performed with a high performance hot mix asphalt concrete (HP-HMA) at different stresses and loading times. Depending on the hardening law considered, permanent deformation data predicted by the proposed model results are reasonably consistent with the experimental creep-recovery data. A rational constitutive model that is physically congruent with the creep phenomenon of asphalt concretes was developed and calibrated to achieve a deeper understanding of the stress-strain response of such materials. The fundamental relevance of an appropriate plastic response modeling, in the study of the creep behavior of asphalt concretes for highway and road pavements.

This study investigates the seismic performance of point-fixed glass façade systems (PFGFS) through a full-scale experimental campaign conducted at the University of Coimbra. Two façade systems were tested, accounting for two fixing configurations: fully drilled countersunk bolts and partially through (embedded) bolts. Each system consisted of nine glass panels arranged in a 3 × 3 configuration, with individual panel dimensions of 1490 mm × 1490 mm. The façade systems were subjected to quasi-static cyclic loading to assess their in-plane drift response and post-fracture behaviour. Results indicate that failure initiated in the middle row, yet the façade system remained functional, sustaining additional loading cycles without complete failure. Maximum lateral drift ratios were 2.12 % for partially through bolts and 2.28 % for fully drilled bolts. Deformations were accommodated through rigid body motion, bolt rotation, and sealant relaxation, with washer yielding acting as a sacrificial mechanism to absorb deformation. The lamination foil played a crucial role in retaining shattered glass, ensuring post-failure integrity, and preventing the release of hazardous debris. A finite element model (FEM), validated against experimental results, successfully captured the façade's force-displacement response, confirming progressive failure behaviour. These findings highlight the ductility of point-fixed glass façade systems and demonstrate their capacity to sustain lateral displacement while maintaining structural stability. The results provide valuable insights into the deformation capacity of glass façades, enhancing the understanding of their safety and resilience in seismic regions.
