However, the generated heat island and their energy-environmental consequences emphasize the need to rethink the way of tree plantation in the city. Therefore, the goal of this study was to evaluate the effect of different urban-forest schemes on residential energy consumption. For that purpose, nine representative urban canyons were micro-climatically monitored in winter and summer and the thermal behavior of a prototype housing inserted in each urban canyon was simulated. The results indicate that the urban designs that control the solar radiation by means of an adequate distribution of the shade and that allow a better wind circulation, minimize the auxiliary energy consumption up to 30%. This allows generating feasible technical proposals to incorporate into urban codes and therefore, more efficient use of trees lined.","PeriodicalId":54981,"journal":{"name":"Informes De La Construccion","volume":"70 1","pages":"239"},"PeriodicalIF":0.6,"publicationDate":"2018-04-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48784696","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It was opened the 6 of June of 1918 after having suffered two collapses, one during the execution in 1916 and another during the load test made in 1917. Later the building was subjected to a satisfactory load test in 1918 that offered the necessary guarantees to authorize the inauguration. In 1921 the Governor decreed the closure of the building by alleged structural problems, being demolished in 1930 after a decade of oblivion. In this work are collected documents scattered in several archives, that allow to determine that the load test of 1918 was rigorous and that the behavior of the structure was correct, showing its strength even during the demolition.","PeriodicalId":54981,"journal":{"name":"Informes De La Construccion","volume":"70 1","pages":"240"},"PeriodicalIF":0.6,"publicationDate":"2018-04-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49435720","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The three-dimensional Urban Models are in themselves fundamental tools to manage the different phenomena that occur in smart cities. It is therefore necessary to generate realistic models, in which BIM building design information can be integrated with GIS and other space technologies. The generation of 3D Urban Models benefit from the amount of data from sensors with the latest technologies such as airborne sensors and of the existence of international standards such as CityGML.

Its use in nuclear power plants has increased with the new regulations to apply risk informed performance-based methods for the analysis and design of fire safety solutions. The selection of the cell side factor is very important in these kinds of models. The mesh must establish a compromise between the geometry adjustment, the resolution of the equations and the computation times. This paper aims to study the impact of several cell sizes, using the fire computer model FDS, to evaluate the relative affectation in the final simulation results. In order to validate that, we have employed several scenarios of interest for nuclear power plants. Conclusions offer relevant data for users and show some cell sizes that can be selected to guarantee the quality of the simulations and reduce the results uncertainty.","PeriodicalId":54981,"journal":{"name":"Informes De La Construccion","volume":"70 1","pages":"238"},"PeriodicalIF":0.6,"publicationDate":"2018-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47449523","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Using Bayesian networks, variables can be classified, predicted and diagnosed, being able to estimate posterior probability of the unknown ones based on known ones.
