Item Collaborative platform based on standard services for the semi-automated generation of the 3d city model on the cloud(CRC Press/Balkema, 2018) Prieto, I.; Izkara, J. L.; Mediavilla, A.; Arambarri, J.; Arroyo, A.; Karlshøj, Jan; Scherer, Raimar; Tecnalia Research & Innovation; LABORATORIO DE TRANSFORMACIÓN URBANA; DIGITALIZACIÓN Y AUTOMATIZACIÓN DE LA CONSTRUCCIÓNThe urban 3D model is increasingly recognized as the adequate support to integrate, harmonize and store the information of a city and make it accessible to all stakeholders (citizens, city managers, companies or researchers). These models facilitate the cooperation of experts in different areas, contributing their knowledge in the generation of a single model. Urban 3D models will allow transforming urban management processes. One example of such processes is the Special Interior Reform Plans (PERI). These urban management processes are developed by the administration, but require the collaboration of different agents. In addition, they represent a clear example of the need to advance in the integration of heterogeneous data at different scales (building and city). The solution proposed in this article presents a platform based on web services for the collaborative generation of urban 3D models. The platform is composed of an information system based on standard data models (IFC and CityGML) and a web services infrastructure that manages the information and relationships stored in the information system at different levels. Besides, a prototype of 3 applications based on the service infrastructure and developed to support the urban management process is presented. The platform is used and tested in the collaborative generation process of the 3D model of the historic district of the city of Vitoria-Gasteiz (Spain) during the definition, editing and monitoring of the PERI of the historic center of the city.Item EIGAPEV, integrated environment for automatic managing of building projects(2006) Mediavilla, A.; Pérez, J.; Azaola, C.; Del Canto, J.; Olalquiaga, A.; SGIn spite of the increasing usage of the Information and Communication Technologies (ICT) in the Construction world, one of the main current challenges is to obtain the interoperability of the different applications used throughout the entire life-cycle of a construction process. EIGAPEV Project is conceived in order to develop a system which integrates the design and management of the building process in a common framework, making use of the power that the interoperability provides. In addition, the system will be integrated in an existing ERP tool used by the professionals of the sector. The modules developed in this system include the direct importation of a CAD 3D design in a budgeting utility, the integration with the scheduling module, being able to simulate and analyse the evolution of the building process and an automatic code-checking module for a local regulation on social houses in the Basque Country.Item Multiscale building modelling and energy simulation support tools(CRC Press/Balkema, 2016) Romero, A.; Izkara, J. L.; Mediavilla, A.; Prieto, I.; Pérez, J.; Christodoulou, Symeon E.; Scherer, Raimar; EDIFICACIÓN DE ENERGÍA POSITIVA; Tecnalia Research & Innovation; LABORATORIO DE TRANSFORMACIÓN URBANA; DIGITALIZACIÓN Y AUTOMATIZACIÓN DE LA CONSTRUCCIÓN; SGBuilding and district modelling (BIM, CityGML…) are key technologies for the deployment of energy efficiency strategies at building and district level, from the initial stages of planning and design to the operation and maintenance ones. These technologies allow satisfying the interoperability requirements that facilitate the cooperation among the multiple stakeholders and provide the framework to develop more intelligent tools. This paper introduces five complementary European R&D projects in which TECNALIA is collaborating, very good examples of innovative systems based on these concepts. MOEEBIUS enhances passive and active building elements modelling approaches enabling improved building energy performance simulations. HOLISTEEC focuses on building multi-physical simulations considering the neighborhood context. FASUDIR exploits the high potential of GIS tools for urban sustainability analysis and accurate building energy performance evaluation. EFFESUS integrates district and building scales in historic districts. OPTEEMAL develops a platform at district level, based on an IPD approach.Item Renobim: Collaboration platform based on open bim workflows for energy renovation of buildings using timber prefabricated products(CRC Press/Balkema, 2018) Mediavilla, A.; Arenaza, X.; Sánchez, V.; Sebesi, Y.; Philipps, P.; Karlshøj, Jan; Scherer, Raimar; DIGITALIZACIÓN Y AUTOMATIZACIÓN DE LA CONSTRUCCIÓN; Tecnalia Research & Innovation; EDIFICACIÓN DE ENERGÍA POSITIVAAEC industry is by far one of the most fragmented industries, with still important data and process silos. This paper presents an innovative platform developed in H2020 funded BERTIM project to overcome this barrier in the field of building energy renovation using timber prefabricated products. It supports the overall process from BIM creation using laser scanning techniques, assessment of the renovation project feasibility and selection of the most cost-effective alternative to be then produced by CNC machines. It follows the decision-making methodology developed in the project, involving several stakeholders (service provider, designer, manufacturer and potential client of the renovation process), as support their collaboration, with relevant time savings and better knowledge sharing. The platform implements Open BIM workflows through the interoperability of tools using IFC files, linking custom developed decision support tools, existing energy simulation engines (Energy Plus) and CAD/CAM tools, with secondary objectives like running cloud energy simulations by non-expert users. Simulation models are automatically created in two approaches: procedurally created models from user inputs (for early deci-sions), as well as an advanced IFC to Energy Plus conversion in detailed phases. Additionally, the user can quickly define the façade splitting configuration to be added to the existing IFC and conveyed to the CAD/CAM tool for manufacturing. 3D model visualization is supported using Web3D technologies. The final platform is easily adaptable to different manufacturers’ processes and products.
