REPORT ON SOCIETAL IMPACT

BIM4EEB is a project introducing a BIM-based toolkit for efficient renovation. The aim of the project is to ease the process of building energy renovation, which provides benefits for many stakeholders such as owners, tenants, designers and many other third parties. Through a BIM Management System (BIMMS) and its interfaces, the actors of the process can interact with the building models, sensor data and construction information. The effect of an intervention on the built environment can be categorized in three main impacts, i.e. environmental, economic and social impacts. While the first two ones are relatively easy to assess with quantitative analysis, also sustained by BIM-oriented technologies, it is much different to assess impacts on individuals and the society. This document proposes a Social Impact Assessment (SIA) method to measure the effect of BIM4EEB on the stakeholders involved by it. This framework will be then used and validated at the end of the project.

List of Designers’ Needs and Requirements for BIM-Based Renovation Processes

Key elements in the renovation process are the performance based building design in the early phases, where the most important decisions are made according to costs and performance, and enhanced collaborative design work. All tools should comply and support this approach. The performance based building design process assumes that design selections are validated against the Owners Project Requirements (OPR’s) in each design stage before moving to a following design stage. The BIM Assisted Scenario Simulator will tackle the complexity of the energy and indoor climate design by speeding up the decision making, enhancing the collaboration between the design domains and enabling the cross domain transparency of the technical details in the design team, that results in better indoor climate and energy selections in the renovation.

List of construction companies’ needs and requirements for BIM-based renovation processes

The construction sector (AEC) has been facing several changes related to technology and innovation in order to improve the building process. Some enterprises are already making moves towards digitalization and are achieving good results, but some barriers exist when trying to adopt a new approach. The goal of the research presented in this deliverable is to identify construction companies’ needs to promote the development of an efficient and effective way to exchange information. An online questionnaire was sent to construction companies in Europe in order to figure out the best way to help the companies to satisfy their needs. The respondents profile shows that they are responsible for different roles in the construction process and that they work with different types of projects. It has been proven that the exchange of information can be improved by using different management tools and by practicing collaboration between all the actors. It is possible to say that the companies’ main needs are the improvement of the exchange of information, by using better or more specific software of data management, as well as, by updating the drawings as soon as possible to avoid change during or after the construction phase. The results presented are valid not only for new buildings, but also for renovation practices. Renovations can be very complex from the point of view of data collection and information exchange, however there are technologies and team work collaboration methods already applied in new buildings project, that would improve the process and increase the quality of the deliverable if applied also to renovation projects.

List of owners’ and inhabitants’ needs and requirements for BIM-based renovation processes

The scope of deliverable D2.5 is to identify the needs and requirements of the building owners and inhabitants in respect to renovation interventions, considering them as stakeholders of the BIM4EEB project and end-users of the proposed toolkits. This deliverable supplement the activities undertaken in Work Package 2, which details the definition of requirements for an efficient renovation process, through the utilisation of the BIM4EEB platform. The extraction of the building owners and inhabitants requirements is based on a “hybrid” engagement approach; driven by the feedback received from questionnaires circulated in the preselected pilot sites of Italy, Poland and Finland, along with engagement of the pilot site representative partners in semi-structured interviews (ALER & Reg Lomb being responsible for the Italian site, Prochem being responsible for the Polish site and Caverion being responsible for the Finnish site). The outcome of this document resulted in the documentation of the building owners and inhabitants requirements including some technical and non-functional requirements, as well as pilot specific requirements and ethical, legal barriers as identified from the pilot site representative partners. The final list of the extracted requirements will form the basis for the design and development of the work packages of the BIM4EEB project, as well as provide the required inputs for the definition of the BIM4EEB technology framework architecture and specifications.

A BIM-BASED FRAMEWORK FOR BUILDING RENOVATION USING LINKED DATA

Accurate and efficient renovation projects require better management and utilization of information about existing buildings, objectives of renovation, designs of end results and performance of the building construction plans, and progress of execution. BIM4EEB uses the Linked Data approach as a glue between different data sources at technical and syntactic levels to make data interlinked and accessible. The goal of WP3 is to adapt the Linked Data approach at the semantic level to the renovation domain, through the identification and development of appropriate vocabularies. Task 3.1 introduces the overall Linked Data framework, outlines the vocabulary requirements in the renovation domain, analyses existing ontologies covering specific areas of the required vocabulary, and identifies gaps where new ontologies should be developed, or existing ones be extended or refined. To facilitate the shared ontology work, it also specifies the tools and practices for ontology development, publication and documentation.

AN ONTOLOGY FOR REPRESENTING DATA

Deliverable D3.3 focuses on BIM data representation in different Levels of Detail (LOD) corresponding to the renovation process modelling. The modelling approach in this deliverable corresponds to the renovation workflow processes specified in Task T 2.1 of BIM4EEB. It aims to address the current deficit in specifying the varying scope and detail of product models over the different lifecycle stages. This difference of scope and detail results from the various information requirements of the distinct stakeholders being actively involved in the several building lifecycle phases.The development goal is a Digital Construction Lifecycle (DICL) ontology which describes the different activities, tasks, and sequences and their interrelations to stakeholders involved and the information required.

HARMONIZED COMMON DATA EXCHANGE FORMATS

Communication between designers, builders, users and owners, transfer of data between domain-specific platforms and information storage and management together represent fundamental aspects of the complex topic of interoperability in the Architecture, Engineering and Construction (AEC) sector. The well-known Industry Foundation Classes (IFC) standard is the most important standard proposing a data model for the built environment, modelling both geometrical and non-geometrical information on a common format. Nonetheless, the expressivity of IFC is addressed as one of the causes for a limited application on the market. Recent research works, though, suggest the implementation of Semantic Web technologies, in particular the use of ontologies for knowledge representation, in order to overcome the linking and communication of data from different domains and sub-domains. This document aims at harmonizing the results from previous Tasks of the same Work Package, by analysing the existing standardization framework and recent research efforts and, finally, highlighting possible features for a new data exchange standard to be presented at European level (CEN TC 442).

AN ONTOLOGY TO REPRESENT RENOVATION WORKFLOW

The ongoing digitalization of construction industry is changing the methods for managing renovation projects. This deliverable describes a set of ontology modules – for Contexts, Variables, Entities, Processes, Agents, and Information, belonging to Digital Construction Ontologies (DiCon) – for the representation of processes in the delivery phase of renovation projects. They make it possible to represent the connections between activities and the various kinds of entities that can be directly observed – building objects, information objects, delivery teams, task teams, locations and workspaces, equipment, materials, and external conditions – thus paving a way to systems that can related real-time sensors data to renovation activities. The ontology also addresses the dynamic evolution of information during project execution: information can be represented at multiple different contexts and additional metadata can be provided about the information, supporting change management. The ontology builds upon the standards that address the digital exchange of information in construction domain (ISO 16739 IFC, ISO 19650 BIM/IM, ISO 21597 ICDD), ontology standards (ISO 21838 BFO), and other established ontologies.

INTEGRATED LINKED DATA

This Deliverable presents the BIM4EEB approach for the development of a Linked Data Modelling and Sharing Framework to be used in renovation projects for residential buildings aiming to improve the present renovation scenarios, example workflows, energy efficiency, ..etc. One major “road block” to organize the planning, design, and execution of renovation activities holistically and comprehensively is the lack of efficient data and information sharing. The work in Task 3.6 in WP3 of the BIM4EEB-project aims this deficit. The proposed approach using the concept of Modular Ontologies will support the integration of available knowledge repositories, describing the “pre-renovation” status of buildings. Thus, decisions about what and how to renovate can be made faster and in an “informed way”. Secondly, it is known from the literature that user behavior impacts the energy consumption of buildings. Therefore, a substantial part of the ontologies developed in WP3 focuses on “occupant behavior modeling” and “user comfort modeling”. A third pillar in the development of the BIM4EEB modular ontology is the knowledge management for “workflow and process management”. The achievement presented in this deliverable is a Linked Data Modelling and Sharing Framework based on a “Modularly Networked Set of Ontologies” (Digital Construction Ontologies) consisting of ontologies developed by BIM4EEB complemented by ontologies developed by “Third parties” and already well established in the W3-community.

Report of Existing Techniques and Recommendation of Mapping Technique

Fast mapping of buildings is a key factor in the renovation process. This report investigates different mapping techniques and gives a recommendation for the use in BIM4EEB project. Recommendations of fast mapping technique depends on how fast the mapping needs to be and also how good accuracy that is needed. The accuracy decided in the project goals should be not more than 1 cm deviation. Only one solution tested for this report actually matched the project goal of reducing the time for mapping a building. That was the the app called Magic floor plan. In this app the user is aided with image recognition and AR technology to select only the important features of a room (such as corners). This data is then instantly converted to a 3d model (but with a low accuracy). In terms of scanning walls, investigations of different sensing technologies has been done. Because none of the products meet the requirements themselves, the recommendations are to combine technologies and positioning systems. A solution that automatically create a model from scanning has not been found

Methods and tools for selecting devices and linking them to the generic model

This deliverable D6.2 covers Research and Development (R&D) results and explains the supporting tools for relative stakeholders involved in renovation of existing buildings at the post-procurement phase. The outcome is based on the existing AUTERAS tool suite. That tool suite was initially developed by the TUD and originally designed to outline new Room Automation Systems (RAS) during the planning phase of their development. RAS are part of Building Automation and Control Systems (BAC). The limitation of RAS results is based on the availability of semantical functionality descriptions, which are currently only available for RAS functions. Furthermore, this report summaries enhancements of the AUTERAS suite in order to fulfil new renovation tasks. Some main improvements include an IFC importing for existing building data – a new methodology to cope with retrofit scenarios and for replacement of the existing device search algorithms. This works for the automatic design generation which had to be revised to enable it to handle the renovating task. The “IFC importer” enables an AUTERAS’ user to reutilize existing data about those buildings under renovation. It is designed as a “web-service interface” to access IFC documentation (located in the BIM Management System, BIMMS) allowing an automated rebuild of the known building’s structure within the AUTERAS tool. To properly integrate this information with the AUTERAS suite for the new scenario of retrofit, the following had to be considered: new user guidance; handling design generation requests; and representation of results. Thus, the device-search algorithm, as the core component of the automatic design generation process, had to be enhanced in order to handle existing designs on the initial planning phase. The reworked design generation option was integrated into the new workflow to improve users’ experience when selecting, replacing and linking devices in the existing layouts of generic model

Ambient User Interface

The main purpose of this deliverable is to develop a user-friendly web-based application dedicated to building occupants (i.e. Inhabitants and Owners), enabling them to be part of the BIM4EEB project ecosystem. More specifically, the building occupants should be able to provide input regarding their comfort preferences towards the extraction of their accurate comfort profiles, enhancing that way the personalization of the different applications developed in the BIM4EEB project. In addition, through the provision of context analytics dashboards, building occupants can get insights about their personal comfort preferences and further comfort related context analytics; as well as monitor their energy consumption on the way to raise occupant’s awareness in energy efficiency and their buildings energy performance. Upon consideration of the main requirements identified in the project complemented by the BIM4EEB pilot site representatives’ partners’ feedback; the developed application offers the following three major functionalities for building occupants: 1. Visualisation of both real time and historical information regarding individual comfort related parameters such as indoor/outdoor temperature, humidity, air quality and Illuminance; supplemented with context analytics. 2. Occupants input provision regarding their thermal and visual comfort status against set values of temperature, illuminance 3. Visualisation of energy consumption at apartment level, through a user-friendly dashboard, supplemented with context analytics Different views are available for the two stakeholder types: inhabitants and owners taking into account the level of details on the available information. Also, the overall framework is developed in a modular approach ensuring the proper visualization of information considering the level of data availability on each building site. The above-mentioned functionalities are provided with the context of the developed application, named as: BIM4Occupants - An application for building occupants engagement and interaction. Additional views are incorporated in the app (under the context of T7.2) towards setting a holistic building management framework for building occupants and building owners.

Open format and formalised requirements specification for procurement

Before the procurement of components of a system, the system must be planned as technology- and manufacturer- independent. The planning process of new building, as well as their renovation, is a very complex procedure. As mentioned, many different trades have to work together, while different terms and notations impede these collaborations. This has an impact not only on complete processes’ planning, but also on the resultant effectiveness of the Building Automation Systems. Electricians, system integrators, lighting experts, heating engineers and many more professionals have to work very closely together in order to achieve a result in the form of energy-efficient buildings with a high level of comfort. The tool suite AUTERAS (Technische Universität Dresden, 2013) supports planners to design Room Automation Systems (as part of Building Automation Systems) with a semi-automated process of functional requirement survey and generation of functional block-based designs, which use standardized symbols to ensure a high comprehension from stakeholders in different trades. The resulting designs can be used directly to form bills of quantities for the procurement process. Therefore, the specification of functional and non-functional requirements is explained in this D6.1 report with use of current AUTERAS-based high-end knowledge and achievements. To ensure a high energy efficiency of the resulting Room Automation Systems, special attention was taken to the consideration of Energy Efficiency Classes as an example for non-functional requirements. Furthermore, the common web-based system model for the designs of the Room Automation Systems was established, so that other subsequent stakeholders will be able to re-use them directly.

Report on management of real Best Practice Examples

The research activities for Demonstration in relevant environment (WP8) started from defining how to manage tools and methods on the three best practice examples selected for BIM4EEB validation. These pilot sites will allow testing and demonstrating the features of the different tools, according to a designed testing methodology and consequently a selected hardware topology. In order to manage such validation activities, the report shows the gathered information about existing residential building and explains the reason why some apartments were selected for the validation of the developed tools: on one hand, the selection of apartments considered the availability of residents of individual apartments for demonstration activities and diversification due to their exposition; on the other hand, this selection was based on detailed analyses of the technical condition of individual apartments. Moreover, it shows the testing methodology applied on the chosen pilot sites to check if functionalities of the different tools within the BIM4EEB toolkit work and, thanks to the use of Key Performance Indicators (KPIs), how much they can improve efficiency the renovation process and comfort conditions. The hardware topology described in this report was defined for addressing the task requirements about: • Thermal and visual comfort (i.e., temperature, relative humidity, occupancy, luminance); • Indoor air quality (i.e., CO2, PM2.5, PM10, VOC - Volatile Organic Compound); • Electric power consumption (i.e., electricity meter); • Gas consumption (i.e., gas meter) Sensors and devices that measures such parameters are then linked to a system gateway, thanks to the connection to its API, data can be stored into the BIMMS. Eventually the report describes the validation methodology with the respective KPIs in order to validate the level of success and assess the BIM4EEB project results.

Report on demonstration in Finland

The Finnish pilot building is a five-floor apartment building built in 1992 and located in Espoo, Finland and represents a typical technology which has also been used in many other apartment buildings, constructed in 1970’s and 1980’s. Installing an exhaust air heat pump (EAHP) was found to be the most suitable measure to improve the energy-efficiency of the building. Four of the BIM4EEB toolkit tools were demonstrated on the pilot. BIM Management System (BIMMS) was used as a common data environment to store the building’s BIM model, documentation, sensors streaming, activities and alerts. Fast Mapping Toolkit demonstrated visualizing and modelling features and BIM Early-Stage Energy Scenario tool (BIMeaser) collected the available data for semi-automatic energy modelling. Construction production management tool (BIMPlanner) demonstrated how the renovation project activities can be monitored using BIM based location breakdown structure. The monitored and simulated results in energy efficiency improvement and expert estimates for other indicators are very promising. The renovation works enhanced the energy efficiency during the measurement period by 33% of the total facility energy compared to the baseline consumption. According to the simulations the yearly savings in facility energy consumption could be 35%. Analyses of the energy renovation time revealed that a potential time saving in similar projects would be up to 33%.

The methodology that is applied in this report is centred on four pillars: 1. The recognition of relevant standardization bodies, technical committees and standards 2. Definition of strategy in relation to the standards 3. Roadmaps and internal processes 4. Liaison and communication Each of these steps is applied to the individual key exploitable results or research results that were identified during the preliminary phases of the BIM4EEB project with the objective of obtaining: • Selection of standards bodies and forums that are developing the world leading standards in the identified technical areas • List of relevant and prioritized standards affecting project results • Which components or parts of research results is most affected by the identified standards with particular emphasis on specific project tasks • Gap analyses of current standards and an assessment on whether or not research results can constitute the basis for standards extensions • The establishment of project internal processes for standards strategy and contribution development, alignment and review • The identification of delegates for targeted standardization bodies in case of need for liaison for standards creation and extension This process will provide a development foundation for all research efforts with possibilities for benchmarking developments and outlining the different requirements that exploitable results are subject to. Moreover, it will help highlight the truly innovative areas of the project through the identification of potential standards extensions.

Dissemination and Communication Plan - Annual revision 24 M

Communication and dissemination through targeting the different audience and consumer groups are the aim of the BIM4EEB approach. This plan aims to make a summary of the past year activities and present the next actions to fulfil the dissemination and communication KPIs established in the project. At the beginning of 2020, the pandemic outbreak required a new approach to the dissemination and communication activities. All actions were shifted to BIM4EEB digital channels. Overall, planned events were highly impacted, as some were cancelled, and others postponed and shifted to online platforms. This deliverable gives the opportunity to have a glance at the activities performed and plan the upcoming activities. Therefore, the involved partners can better align their activities. The project second year has been the “Tools’ development year”. During the third, we disseminate them and measure their impact.
