This paper makes an intensive study of the realizations and related key technologies in the 3D urban traffic simulation system. First, the system can quickly edit the scenes of the 3D urban, including buildings, roads, etc. It describes the roads using the graph structure, then, the constrained Delaunay algorithm is applied to reconstruct the mesh of the road and terrain. The most important, th...

The paper describes OptiHab study, done in the framework of the MARIE project. The objective of OptiHab is to provide technical and economic information to optimize the energy renovation of residential sector in Catalonia, ensuring the comfort of the users. The information of the study gives the criteria to develop regional strategies and policies to improve the energy efficiency of the residen...

This paper presents a contribution for the safety assessment of historical masonry buildings under seismic loading. Three different simplified safety indexes (in-plan area ratio, area to weight ratio and base shear ratio) are analyzed, taking into account a large sample of fifty-eight Portuguese churches. The sample of building has been organized according to the seismic zonation, from high to ...

The dataset presented in this paper constitutes one of the outcomes of RÉPENER, a research project co-funded by the Spanish National RDI plan. It contains integrated information of the Spanish territory regarding energy certification, building monitoring, and geographical data. The integration has been carried out by means of semantic technologies. The adherence to the Linked Data principles gu...

This paper summarizes the results of a recent investigation on the dynamic response of asymmetric-plan buildings with supplemental viscous damping to harmonic ground motion using modal analysis techniques. It is shown that most modal parameters, except modal damping ratios and dynamic amplification factors, are affected very little by the plan-wise distribution of supplemental damping in the pr...

The gap between the intended and actual energy performance of buildings is increasingly well documented in the non-domestic building sector. Recognition of this issue has led to the availability of a large range of initiatives that seek to ensure energy efficient building operation. This article reviews the practical implementation of three such initiatives in a case study building at the Unive...
