Workshop: BIM4EEB: A BIM-Based Toolkit for Efficient rEnovation in Buildings

Abstract

On October 29th the workshop corresponding to the mid-term conference of BIM4EEB (Acronym of BIM Based Toolkit for Efficient rEnovation in Buildings, Horizon Project under grant agreement N. 820660 ) project was held during the Sustainable Places 2020 event. The main focus of the workshop was a general introduction of the project combined with vertical insights on the single tools that have been developed or are still in development. BIM4EEB grows from simple consideration: according to a BPIE analysis on EPC data, about 97% of building stock, currently not in A level, must be upgraded to achieve 2030 decarbonization objectives. As the biggest energy consumers, buildings consume about 40% of energy and they are responsible for 36% of CO2—they are strategic in order to reach the set of environmental goals and subjected to renovation and refurbishment during their lifecycle according to a specific schedule. Refurbishment becomes the crucial point of sustainability not only in construction but also in the environment in general for the coming years. The BIM4EEB project focuses on implementing a complete BIM (Building Information Modelling)-based toolkit to be adopted in the renovation of existing residential buildings to make the flow of information efficient, to enhance communication and data transfer decreasing intervention working time while improving building performances, quality, and comfort for inhabitants. The platform that controls all the tools developed for the best performance of renovation is BIMMS (Acronym of Building Information Modelling Management System platform), namely a management system linked to an operational and multifunctional toolkit for different AEC stakeholders, offering tools for increasing the adoption of BIM in renovation businesses based on an interoperable flow of information. During the workshop, six development tools have been explored in addition to the BIM Management System: BIM4EEB Fast Mapping of Buildings Toolkit, BIM4EEB BIMeaser tool, BIM4EEB BIM4Occupants tool, BIM4EEB Auteras tool, BIM4EEB BIMcpd tool, and BIM4EEB BIMPlanner tool

The Development of a BIM-Based Interoperable Toolkit for Efficient Renovation in Buildings: From BIM to Digital Twin

“…Collecting and managing information about existing buildings is crucial for the building renovation, in all stages of the construction process, i.e., design, construction, and operation. Hence, the BIM4EEB Project integrates a group of digital tools within a web-based platform, i.e., an innovative BIM management system (BIMMS) for designers, construction operators, and inhabitants, to facilitate the renovation processes through collaboration [15]. Exploiting linked data, this toolset integrates the management of different activities that can be developed by different stakeholders of the renovation process, from designers, constructors, supplies, and public authorities, to end users and operators [29].…”

“…BIM4EEB, a BIM-based fast toolkit for the efficient renovation of residential buildings, focuses on the implementation of a complete Building Information Modelling (BIM)-based toolkit to be used during renovation of existing residential buildings, in order to increase the efficiency of the information flow, decreasing intervention working time while improving building performances, quality, and comfort for inhabitants. Among its main objectives are the reduction of at least 20% of renovation time, 15% of the average renovation cost, 10% of net primary energy use for a residential flat, and the reduction from 3 to 1.5 working days required for a deep energy audit [15]. Given these objectives, to assess their achievement the project uses a validation methodology based on key performance indicators (KPIs).…”

“…A multidisciplinary approach was adopted within the project, relying on the collaboration and integration of different skills, competences, and needs, considering buildings' and informatics competences, public and private research, small-and medium-sized enterprises (SMEs), large enterprises, technology providers, end users, inhabitants, and the European umbrella organization representing all 600,000 European architects present within the consortium [15].…”

“…BIM4EEB is developing a BIM management system, an open, integrated BIM-based collaboration environment, enabling the continuous updating, enhancement, improvement, and enrichment of available models by the AEC industry stakeholders based on robust modeling guidelines that will be provided by the project, to ensure the sustainability of project developments and enhance its exploitation potential even after the end of the project [15].…”

“…From a technological point of view, BIM4EEB will offer an easy, practical, operational, and multifunctional tools set for different actors of the construction industry, merging tools for improving BIM adoption in renovation works based on an interoperable flow of information [15].…”
