Periodic Reporting for period 2 - BIM4EEB (BIM based fast toolkit for Efficient rEnovation in Buildings)
Periodo di rendicontazione: 2020-07-01 al 2022-06-30
The EU has set an 80% reduction goal in primary energy consumption by 2050, but the overall improvement in energy efficiency is offset by the low renewal rate of the existing buildings (about 1% annually) compared with the target (2,5%) necessary to redevelop the entire EU asset. BIM4EEB propose methods and tools for overcoming barriers arising in different stages of the renovation process through different connected tools. The project objectives are:
OBJ 1 - TO MAXIMISE EFFICIENCY IN BUILDING RENOVATION
BIM4EEB covers each stage of a renovation considering: time reduction; cost saving; building quality control and net primary energy use decrease; disturbance experienced by the inhabitants decrease. Detailed and interconnected information enables smoother data flows and interaction between parties and through: faster survey, BIM modelling and checking, clash detection, energy audit and efficient time management. An improved accuracy leads to reduction of unexpected variations, work suspensions and re-works costs. The centralization of all data allow quality driven corrective actions during and after renovation processes, such as speeding up the comparison process between different renovation options.
OBJ 2 - TO ACCELERATE THE MARKET UPTAKE ACROSS EUROPE TOWARDS A DIGITAL BUILT ENVIRONMENT
BIM4EEB has developed an innovative set of products for the building renovation sector in the form of a methodology and technological platform, providing practical solutions for deriving advantages of BIM implementation within the retrofitting industry. The project has new synergies and centralised modes of interaction, enabling an increase in building renovation rates, alleviating technical barriers with Information and Communication Technology (ICT), lowering financial barriers, and enabling accurate energy savings forecasts. Linked data Geo Positioning enhanced as-build BIM models with additional information and a Digital Logbook store all data, related to the building, and to be exploited mostly in the operational phase.
OBJ 3 - TO SPEED DATA GATHERING AND PROCESSING
Data gathering and processing has been speeded-up through an AR tool for fast mapping of buildings geometry and services. An additional Innovative software platform, connected with BIM models, supports the automated configuration, design, and layout of Building Automation and Control Systems (BACS), through an holistic and standardized data exchange process. User’s preferences about comfort, and feedbacks from building occupants are also collected and inhabitants get insights about building comfort levels as well information about the renovation process.
By analysing data from different perspectives, BIM4EEB speeded-up decision-making for different renovation scenarios.
OBJ 4 - TO ENSURE INTEROPERABILITY AMONG DIFFERENT STAKEHOLDERS AND TOOLS, HARMONISING AND PROVIDING COMMON DATA EXCHANGE FORMATS
The link created between data sources establishes channels of interconnection and communication between parties and relevant stakeholders, reducing the coordination problems caused by the fragmented nature of renovation projects. The BIM management system enable the controlled publication of building data on the Web and the integration of models and datasets using loosely-coupled cross-model linking and a semantic interoperability framework based on Linked Data and Digital Construction Ontologies (DiCon). The central platform provides different services for managing information collected in renovation processes (i.e. BIM models, data coming from sensors, information about the renovation process…) and avoids information redundancy and losses.

Technical specifications of BIM4EEB, coming from stakeholders’ requirements, were completed and the final version of the toolkit was released, for both public and private works, and to be used for renovation processes.
The main methodological and technological advances encompass:
• Digital Construction Ontologies (DiCon) –based on a linked data allowing semantic interoperability among actors and tools;
• A BIM management system - BIMMS - providing features for building data re-use, storage space, aggregation of data coming from different sources for making data interchangeable and interoperable;
• Fast mapping of buildings with an augmented reality tool combining different measurement techniques;
• A standardized data exchange connecting BIMMS with Building Automation and Control Systems (BACS) and a novel occupants’ profiling mechanism;
• Tools supporting the construction production management to organise, plan, and track site operations, and efficiently record the as-built data for implementing digital logbooks, such as to evaluate the energy performances at the design state;
The renovation process was demonstrated to have a reduction of working time (at least 20%), a decrease in costs (at least 15%), in energy audit time (at least 50%), primary energy use (at least 10%) and an improvement in quality control.
Project technical activities have been supported by management, communication, dissemination, and exploitation activities.
BIM4EEB project has been widely communicated, stakeholders have been involved in project activities, technical explanations and demo videos have been created to make BIM concepts and tools easily understandable and cooperation with other research projects continued. In total BIM4EEB dissemination and communication activities reached 324.600 people through 224 activities.
BIM4EEB has initiated a standardization process at European level and has ensured the compliance with existing standards and ontologies, has collaborated with the sister projects in ontology domain, and has evaluated the results in the market at different levels (from the national market to the European one). Market opportunities and barriers have been identified and business models and exploitation strategies have been defined.

BIM4EEB project developed an attractive and powerful BIM-based toolkit able to support designers in design and planning phase; construction companies to efficiently carry out the work, and service companies to provide attractive solutions for building retrofitting.
The case studies have significant energy retrofit potential and the applied retrofit strategies are scalable and replicable.
The toolkit acts on the different stages of renovation processes (from field survey, initiation and design to construction and management) and the project developed guidelines for BIM implementation and providing an easy, practical and operational platform and connected tools.
The impact to the project is manifold and encompasses economic and societal areas. The project promotes the acceleration of the market uptake of BIM solutions and high percentage of renovation business based on BIM for construction companies. The adoption of BIM will increase: renovation rates and growth rate for the sector while decreasing energy consumption; an increment of high-profile workers; and entrance of new innovative SMEs in the construction sector; the increase in the quality standard of buildings. For public bodies managing social housing, BIM usage mean direct saving in the renovation and management of buildings stock, and indirect advantages such as less disturbance of vulnerable people, better living and conformity at lower costs.
