WP1: Foundations for next generation dynamic EPCs (dEPCs): Identifying challenges, needs and opportunities

  • D1.1: Comparative assessment of current EPC schemes and relevant emerging performance paradigms v1

    Due date: 31/12/2020 - Task leader: FRC

    Energy Performance Certificates (EPCs) are a mandatory requirement in the Member States when constructing, selling, or renting a building. This report identifies the methodologies currently used for the issuance of EPCs on a European level, explores the technological and market conditions where D^2EPC will be realized, as well as investigates the challenges of current EPC schemes.

    The methodology followed in this report consists of field research committed as a set of statements with questions relevant to challenging matters of (i) EPCs issuing, quality and control, (ii) EPCs calculation software and tools, (iii) EPCs indicators, and (iv) Qualified experts competence and skills, and desk research committed as a set of statements with questions relevant to challenging matters of EPCs. Concerning the field research, the extraction and circulation of a questionnaire to a list of stakeholders took place.

    The collective analysis of data for the specific features of EPCs revealed that among the twenty-seven (27) EU Member States, fourteen (14) have adopted the methodology exclusively based on calculated energy consumption. Penalties are rare and are mainly addressed to energy auditors. Based on the research of this report, it was revealed that the majority of EU countries do not employ by any means BIM documentation and literacy or digital logbooks for the issuance of EPCs. There is no provision, national requirement, or legal obligation of a Building Management System (BMS) existence in connection with the operational EPCs, and in most of the EU Member States information related to Geographic Information System (GIS) is not included in the EPCs, and consequently, it is not exploited for issuing, validating, monitoring, and verification processes of the EPC calculation. Additionally, analysis across the EU Member States revealed that energy-related financial indicators, as well as environmental/LCA related financial indicators, are not found to be included in current EPCs schemes and procedures in any EU Member State. Although provisions for indoor environmental quality are set in EPCs, there are not covered in current EPC regimes and are not included in the calculation procedure for certification of EU countries. There is no existence of a database describing the energy efficiency features of the building stock as a whole. One-third of EU countries do not have provision for systematic and regular evaluation/assessment of energy assessor’s competence and skills.

  • D1.2: Next-generation EPC's user and stakeholder requirements & market needs v1

    Due date: 31/01/2021 - Task leader: CLEO

    Energy Performance Certificates (EPCs) are important instruments for the enhancement of the energy performance of buildings. Notwithstanding the positive contribution that current EPCs have had on improving the energy performance of buildings, experience has unveiled a number of constraints and limitations. There is a need for a holistic framework for strengthening and improving the quality and application of EPCs, by introducing novel and cost-effective approaches of assessing the energy performance of building envelope and systems. This report aims to identify current drawbacks of EPCs and future trends of the market and relevant stakeholders. The results of this research are anticipated to identify the needs and requirements for the successful implementation of next generation EPCs.

    The report followed two types of methodologies including desk research and field research. The desk research committed as a set of statements with questions relevant to challenging matters of (i), Efficiency of EPC methodologies, (ii) Potential EPC methodologies to overcome past drawbacks (iii) Efficiency of EPC data collection tools and procedures (iv), penalties and sanctions currently in force for EPC non-compliance (v) current EPC databases and access. The statements were answered with as a set of questions relevant to current and future challenging matters of EPCs. Concerning the field research, the circulation of two types of questionnaire was conducted according to the ‘Stakeholder identification and prioritization’ section to a list of stakeholders. The purpose of the field research was to identify current drawbacks and future trends of EPCs from the end-users and technical stakeholder’s perspective. The results of both desk and field research resulted to a set of challenges and recommendations for the next generation EPCs.

  • D1.3: Aspects of Next generation EPC’s definition v1

    Due date: 31/01/2021 - Task leader: KTU

    Based on this report's research, it was revealed that the majority of EU countries do not employ by any means BIM documentation and literacy or digital logbooks for the issuance of EPCs. Even though there is the provision of BIM (Building Information Modelling) documentation and digital logbooks in some countries, these are used as a source of information for the EPC assessment procedure or energy simulations.

    Based on the findings of this report, it can be stated that BIM is considering as a significant part of DT (Digital Twin) with semantically rich and geometrically accurate data, both BIM and DT concepts are applicable to increase efficiency in AECO (Architecture, Engineering, Construction and Operation) industry throughout different building life cycle stages, BIM users can benefit from the reduction of energy due to energy performance-related components: building system analysis and management; asset and space management; simulations on design and operation stages; better decisions for investments; reduction of operational costs (energy as well)

    The introduction of novel aspects in the certification process includes the smart-readiness level of the buildings, human comfort-related indicators, and environmental aspects (LCA).

  • D1.4: D^2EPC Framework Architecture and specifications v1

    Due date: 13/04/2021 - Task leader: CERTH

    This report presents the results of Task 1.4 – Architectural Design, Functional & Technical Specification describing the D^2EPC system architecture. The overal goal of this report is to provide a holistic view on the D^2EPC system architecture, its building blocks, components, interdependencies among
    components and related constraints such as development methodology. Starting with the methodology, a brief overview of most commonly identified processes and standards are covered in order to understand and present the steps and the information that need to be covered towards presenting a system architecture that completely covers the needs of the D^2EPC framework. Following a four step methodology, the user and market requirerements extracted through previous WP1 activities are translated to business scenarions and technical users cases, along with functional and non-functional requirements. These are then used to update the overall concept and high-level conceptual architecture, which then guides the more careful and accurate definition of each individual component as a module and as part of the overall system.

    Out of the examined approaches, four initial viewpoints have been selected to be adopted from presenting the details of the D^2EPC architecture: i) Functional, ii) Deployment, iii) Information, and iv) Dynamic views.

    Throught the T1.4 activities 4 business groups have been identified, including in total six (6) business scenarios, further divided into 19 Technical Use Cases. At the same time, a more elaborate iterative approach, usinγ the JIRA framework revealed a first set of 44 requirements (34 functional and 10 nonfuctional), which are documented following the Volere Template. Both the Business Scenarios and the System Requirements, introduced technical aspects that led to the re-design of the D^2EPC architecture. Following a layered approach, the D^2EPC architecture has been divided into 4 layers, each hosting different D^2EPC components, as follows:
    - The Infrastructure or Physical Layer consists of one of the core layers for dynamic EPC, especially for the operational rating. Within this layer, all devices, sensors, actuators, and in general Internet of Things, and systems (i.e. Building Management System – BMS, Energy Management System – EMS, or even Supervisory control and data acquisition - SCADA) are included for collecting the necessary building information for all upper layers. As weather data are also required, in the absence of accessible weather stations on site, external weather APIs will be used to retrieve the necessary information.
    - The Interoperabity Layer consists of one main D^2EPC component, i.e., Information Mangement Layer. This component is responsible for communicating with the building assets from the physical layer, retrieving the necessary information, translating it to a commonly accepted format and streaming it to the D^2EPC repository to be further utilised in other D^2EPC layers.
    - The Service/Processing Layer consists of most D^2EPC components and sub-components responsible for delivering all the main functionalities envisioned:
          ◦ BIM-based Digital Twin,
          ◦ D^2EPC Calculation Engine
                ▪ Building Performance Module,
                ▪ Asset Rating Module, and
                ▪ Operation Rating module,
          ◦ Added-value Service Suite for D^2EPC
                ▪ Roadmapping Tool for Performance Upgrade
                ▪ Building Energy Performance Benchmarking
                ▪ Performance Alerts & Notifications
          ◦ Extended dEPCsApplications Toolkit
                ▪ Energy Performance and Credibility
                ▪ AI-driven Performance Forecasts
    - The Representation Layer constitutesthe layer that is offered for interaction with the endusers (engineers, building owners, registries, etc.) or third party platforms / tools (i.e. blogbooks, BIM desing tools, etc.). Within this layer, three D^2EPC components are included, namely:
          ◦ D^2EPC Web Platform
          ◦ D^EPC Web GIS, and
          ◦ Credibility UI.

    Based on this layered architecture, functional, deployment and information viewpoints have been provided, presenting for a more detailed analysis of each individual component, along their inbetween interactions.

    Finally, the dynamic view, covers several use cases per business scenario, each instantiated through specific requirements and sequence diagrams. The purpose of these sequence diagrams is to clarify how the D^2EPC platform will work and which components are relevant to achieve different tasks.

    As the project continues and the activities within technical workpackages progress, the technical aspects of the D^2EPC framework will become clearer and more specific. Hence, more elaborate details are expected to be delivered in the next versions of this report, with certain aspects to be reevaluated and refined.

 

WP2: Development of the Operational Framework for dEPC Schemes

  • D2.5: D^2EPC Information Model for Next Generation EPCs v1

    Due date: 09/09/2021 - Task leader: KTU

    The main aim of the task T2.5 D^2EPC Information model is to extend current standards/protocols used for issuing certificates and include Smart Readiness, Human-Comfort and Wellbeing, Life Cycle Assessment and Cost and Economic indicators delivered under tasks T2.1-T2.4. This report presents the IFC parser (API) guidelines in what way information for those indicators’ calculation will be extracted.

    Deliverable consists of two main parts:
    i. State-of-the-art analysis.
    ii. Guidelines for extracting required data (concerning KPIs: SRIs, HCWIs, EPIs, LCAIs and CEIs) from IFC.

    The methodology part revealed the differences between asset and operational ratings. The state-of-the-art analysis disclosed IFC’s importance in this project. It was decided to choose the IFC standard because it is an open BIM standard that provides information such as geometry, material, price, etc. In this D^2EPC project, it is crucial that IFC interoperability allows BIM to be integrated into the Internet of Things (IoT), and this data can improve this set of information by providing a dynamic real-time and recordable state of actual construction and performance.

    Data exchange using various BIM software industry fund class (IFC) schemes was offered by Building Smart International. Although IFC can define and transmit the physical geometry of a building, including energy characteristics and construction products and its properties, interoperability problems arise during two-way data flow.

    In the next section, Key performance indicators that are considered important within the EPC issuance process were described. Cost and Economic indicators will be represented later. For the extraction of the relevant data for indicators by using an open international standard, IFC parser (API) guidelines presented in this report are written in Python programming language using open-source IfcOpenShell-Python and Pandas modules. The detailed definition and the code of the application are presented in the report as well. The additional file is added and belongs to the report as additional documentation.

 

WP3: Building digitalisation and inverse modelling for implementing next generation dEPCs

  • D3.1: D^2EPC IoT Platform & Interfaces v1

    Due date: 07/07/2021 - Task leader: HYP

    The objective of D3.1 is to present the overall methodology of T3.1 and summarize the activities conducted until M10 towards the establishment of the D^2EPC IoT Platform. The aim of T3.1 "IoT and BMS interfaces to extract energy-related data" is to deliver the entire IoT framework planned to enable the continuous, seamless, and non-intrusive collection of energy consumption and ambient conditions data from the D^2EPC demonstration buildings, necessary to fulfil the project's objectives.

    Within D3.1, the D^2EPC IoT framework is described in detail, expanding the description provided in the D^2EPC architecture, as defined in T1.4 of WP1. Within T3.1, an optimized IoT topology per pilot building will be proposed taking into account the data requirements of the project and the infrastructure availability on site. Based on this topology, the finalized bills of materials per site with off-the-shelf IoT devices will be defined within WP5 activities. The high-level methodology that defines the per-pilot IoT infrastructure can be described as a step-bystep approach based on the requirements arising from the key performance indicators and the common information model (elicited within WP2), along with the information extracted from the pilot audits in WP5.

    Initially, the D3.1 provides a summary of the pilot Infrastructure. Due to limited information availability on the submission month (M10), the current version includes only a high-level description of the infrastructure available at the pilot sites, including their short description, assets, and existing metering equipment with the respective information retrieval method. The deliverable further dedicates a chapter to the components of the IoT Equipment Framework and the respective equipment evaluation criteria set to overcome the obstacles that occur during the definition and deployment of an IoT Network. The final chapter presents the Information Management Layer component along with its technological capabilities that address the challenges related to big data directly linked to the IoT
    domain. Lastly, the IML and the IoT Equipment Framework are defined within the D^2EPC System Architecture.

    The second and final version of the deliverable (D3.4, to be submitted in M16) will include information on the overall dynamic metric and system operation requirements defined by WP2 and a consolidated version with the IoT infrastructure requirements of the demonstration buildings. Furthermore, D3.4 will document the final specifications and topology of the distributed IoT components to be used, as well as the description and outcomes of the lab or/and remote trials of the proposed IoT equipment. Finally, the second version of this document will describe the incorporation of the Information Management Layer in the D^2EPC data model.

WP8: Project Management & Coordination

  • D8.4: Data management plan v1 & ethics

    Due date: 28/02/2021 - Task leader: CERTH

    The present report is the deliverable D8.4 corresponding to the first version of the project’s Data Management Plan (DMP). Throughout the document, the initial versions of the produced datasets are presented along with the following information:
    - Type and short description of the datasets to be produced, collected and processed;
    - Management processes of research data during and after the realization of the project;
    - Standards and formats concerning the metadata; and
    - Information about data sharing, exploitation and preservation.

    In the light of the required information and considering the guidelines for reports related to “Pilot on Open Research Data in Horizon 2020”, an appropriate dataset template was created and sent to partners who are responsible for specific components and their corresponding produced datasets. In the second part of this report, the procedures that all consortium members will adhere to concering the ethics requirements are presented.

    The D^2EPC project will examine how effective the envisioned solution is by collecting and analysing data in six pilot sites in Greece, Germany, and Cyprus. It is noted that during the realization of the poject procedures, ethical concerns may be raised regarding the privacy and confidentiality of data collection and processing. Such critical issues that may emerge, are considered quite typical in the cases of ICT and IoT projects and initiatives. The D^2EPC consortium has paid full attention in such issues and structured for this purpose an ethical management plan and a pilot ethical methodology following both the European Union (EU) and national legislations. Furthermore, this approach enables secure data exchange among the project members. Further information on these sections is provided within the report.
