Innovative Tools and Methods Using BIM for an Efficient Renovation in Buildings Innovative Tools and Methods Using BIM for an Efficient Renovation in Buildings

This open access book describes a BIM-based toolkit that has been developed according to the latest research activities on building information modelling and semantic interoperability to optimize the building process. It highlights the impacts of using such new tools to fast renovation activities starting from the decision-making and design stages to the construction site management with the possibility to monitor occupants' and owners’ feedback during the realization process. In this process, a framework has been developed and implemented to allow stakeholders involved in a renovation project to efficiently compile, maintain, and add data about (i) building elements, (ii) building services systems, (iii) tenants, operators, and owners of the building, and (iv) current and predicted performance of the building from the various data sources available. The framework applies and specializes the existing practices in the Semantic Web, Linked Data, and ontology domain to the management of renovation projects. It has been designed to be open so that any system which implements the required functions and uses the specified conventions will be able to achieve semantic interoperability with other framework-compliant systems in the renovation domain. Finally, this book represents the validation process of the toolkit that has been held in three demo sites: a social housing building in Italy and two private residential buildings in Poland and Finland. The outcome shows that the toolkit facilitates the renovation process with relevant reductions of time, costs, and energy consumption and that the inhabitants can take advantage of the increase in building performances, quality, and comfort.

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

Nowadays, buildings renovation is a subject of special interest since the building and construction sector is the main body responsible for energy consumption and emissions. Hence, it is necessary to concentrate on refurbishment to achieve Europe’s climate neutrality by 2050 according to European Agenda goals. The BIM4EEB Project, a BIM-based fast toolkit for the efficient renovation of residential buildings, directs the attention toward developing an exhaustive toolkit based on Building Information Modeling (BIM) to be adopted in the renovation of existing residential buildings, to make the flow of information efficient, decreasing intervention working time while improving building performances, quality, and comfort for inhabitants. BIM4EEB is developing a BIM management system connected to an operational and multifunctional toolkit for various architecture, engineering, and construction (AEC) stakeholders, integrating a set of tools for improving BIM adoption in renovation environments based on an interoperable flow of information. This paper presents the Horizon2020 Project and the framework used to develop the toolkit. In addition, the first outcomes of the toolkit development are outlined. The validation procedure in real environments has started to demonstrate the efficacy and applicability of the methodology and tools. Although the project is still in progress, benefits connected to the framework and the BIM-based toolkit result in an enhanced building renovation process.

Check and Validation of Building Information Models in Detailed Design Phase: A Check Flow to Pave the Way for BIM Based Renovation and Construction Processes- Check and Validation of Building Information Models in Detailed Design Phase: A Check Flow to Pave the Way for BIM Based Renovation and Construction Processes-

Model checking of building information models is gaining interest for academic and industrial fields. However, several limitations can be identified in the practical application of model checking processes. One of the main limitations is the unavailability of detailed guidelines describing how these checks should be developed. The research presented in this paper focuses on the development of a check flow that can be applied to any type of building project answering to three main questions, namely what to check, when to perform the check, and who should perform the check. During the research a complete guide for checking activity has been developed identifying the subjects responsible for each specific check during the process.

Ontological approach for LOD-sensitive BIM-data management ldac 2021 Ontological approach for LOD-sensitive BIM-data management  ldac 2021

Since the last decade, LOD is a promising approach for efficient representation of semantically rich BIM data in different levels. Despite the improvement, there is a lack of effi-cient implementation in building lifecycle functionalities, because of their fun-damental heterogeneity, versatility and adaptability. The proposed approach en-ables the representation of LOD-sensitive BIM data through the formal defini-tion of ontologies. The paper validates this approach based on the concept of competency questions and their respective SPARQL queries. With the demon-stration and validation, the paper provides the conceptual proof for the practical application of the developed approach. The proposed solution can also be easily adaptable and applicable to the present BIM process since the representation of BIM data in different ontologies (BOT, ifcOWL, etc.) are within reach.

The BIM process is highly focused on the enrichment and management of domain data and its interoperability between fields. Many developments were proposed for data integration and sharing in terms of common data environments (CDE), multi-model approach, and open data standards (IFC, IDM), etc. However, often the information in BIM models is still managed in other proprietary formats. In April 2020 ISO 21597 (Information Container for Linked Document Delivery - ICDD) was introduced to enhance the semantic connection of heterogeneous data and document structures in the Architecture, Engineering, Construction and Operation domain (AECO) where the usage of different data formats is still of great diversity. Within this paper, we analyse ICDD capabilities, propose a standardised workflow for ICDD deployment and present a use case demonstrating these abilities of ICDD. Finally, an evaluation of the developed workflow is carried out based on Competency Questions and related SPARQL query profiles.

Along the building process the cooperation among several stakeholders and the integration of information during the whole project life cycle, whether it is a new project or a renovation intervention, are two key essential factors. In fact, in AEC sector the loss of information, the lack of data and the improper or repetitive exchange of information are common issues that may cause delays and cost increase. To enhance communication and data transfer, an appropriate rationalization of information flows is necessary. Starting from the outcomes of BIM4EEB, an ongoing Horizon2020 project, the paper analyses the workflow processes to understand how to optimise information workflows among different actors and along different stages by the use of ICT and BIM-based tools. Particular attention was payed to individualise the differences between public and private works in order to provide methods and apply the BIM4EEB approach to renovation process in both cases.

Enhancement of BIM Data Representation in Product-Process Modelling for Building Renovation. PLM 2020 Enhancement of BIM Data Representation in Product-Process Modelling for Building Renovation. PLM 2020

Building Information Modelling (BIM) has the potential to become a technology which will help to use a holistic information repository to generate and represent relevant information in different building life-cycle stages (BLCS) to dedicated groups of stakeholders. However, the scope of model components of BIM data (e.g., IFC meta-data) is limited and some parts of it are not modelled in a manner that supports the diversity of engineering use cases. This paper aims to address this deficit by identifying the capability to formulate inference rules as one of the major benefits in the ontology-based information modelling approach. However, before one can formulate inferencing rules a detailed and in-depth understanding is required on how stakeholder information needs are defined in different BLCS and on how available, open-BIM meta-data models support these information requirements.

A Semantic Data Model to Represent Building Material Data in AEC Collaborative Workflows- PRO-VE 2020 A Semantic Data Model to Represent Building Material Data in AEC Collaborative Workflows- PRO-VE 2020

Building material information plays a vital role in design decisions by enabling different simulation processes, such as energy, acoustic, lighting, etc. Utilization and sharing of building material information between stakeholders are some of the major influencing factors on the practical implementation of the BIM process.However, these schemas have their own constraints to enable efficient data sharing amongst stakeholders. This paper explains these constraints and proposes a methodological approach for the representation of material data using semantic web concepts aiming to support the sharing of BIM data and interoperability enhancements in collaboration workflows. As a result, the DICBM ontology was developed which improves the management of building material information in the BIM-based collaboration process.
