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.

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.

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.

The current report is the deliverable D1.6 which aims to present the aspects of the next generation EPC schemes, as defined within D^2EPC. As a second deliverable version, it steps on and further updates the findings of the previous version (D1.3) submitted in M5. D^2EPC aims to analyse the quality and weaknesses of the current EPC schemes and identify technical challenges that currently exist to overcome them, and set the grounds for the next generation dynamic EPCs.

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 considered 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). The monitoring of buildings' actual energy consumption will enable the development of motivational schemes, which will enforce the continuous improvement of buildings' energy performance. Polluter pays and reward policies will be developed and introduced for those EPC owners who either do not meet or exceed their certificates' expectations, in a similar rationale as with the ETS scheme, aiming
to motivate energy consciousness.

The proposed D^2EPC scheme is expected to transform EPCs into a user-friendly, reliable, and cost-effective informative tool for both the wide public (building users, occupants, owners, etc.) and professionals (building managers, engineers, designers, etc.), as well as to establish the grounds for turning EPCs registries into consistent policy feeding mechanisms. The third and final version of the deliverable is due to be delivered on M36 and will include the complete information, concluding the work under Task 1.3.

This report presents the results of T2.2 – Human Comfort and Wellbeing (HC&W) Indicators Elicitation that delivers the methodology for the extraction of user behavioural profiles that influence the building’s dynamic performance from the scope of occupant’s comfort and wellbeing. To achieve this, the HC&W profiles definition depends solely on streaming and historic data collected by the finalised IoT infrastructures, deployed in the D^2EPC pilots. The document describes the key performance indicators (KPIs) that contribute to the monitoring of the building’s progression, the algorithms and models utilised for the calculation of the indicators and lastly the desirable boundaries of the building operation in regards to various environmental metrics examined within D^2EPC.

Towards a successful assessment of the human comfort and wellbeing, the corresponding performance indicators are formed on well-defined and measurable environmental metrics originating from the building’s raw data. The overall approach is envisioned to be purely data-driven based exclusively on timeseries elements in an attempt to eliminate intrusiveness.

The comfort and wellbeing indicators framework steps on three separate Indoor Environmental Quality domains, i.e., the Thermal comfort, the Visual comfort and Indoor Air Quality (I.A.Q.). Thermal and visual comfort correspond to the occupant’s level of satisfaction with the indoor thermal and visual conditions while I.A.Q. examines the parameters that affect the human respiratory system function as well as the building’s ability to refresh the inhaled air. D^2EPC’s HC&W framework is aligned with European and national environmental and sustainability standards which emerged after a thorough research in the literature. Specifically, Level(s) is heavily considered, which is a European voluntary framework gradually adopted by building specialists towards measuring and reporting a building’s environmental performance.

The literature findings and the envisioned data-driven approach are integrated into a hybrid methodology that delivers the complete framework. On the one hand, KPI reporting methodologies and relevant environmental variables along with their recommended operation limits are obtained from the standards/frameworks. On the other hand, if it’s deemed feasible, the limits are substituted with personalised boundaries extracted from a comfort profiling engine that identifies patterns and trends in the user data. The engine comprises of state-of-the-art clustering algorithms and introduces several innovations in the D^2EPC.

This deliverable is the result of Task 2.3 Energy Performance & Life Cycle Assessment (LCA) Indicators Analysis for Energy Performance Certificates (EPCs), which was created to provide environmental and energy indicators for the next generation of EPCs. The project’s proposed set of indicators aims to improve EPC user-friendliness and raise user awareness by giving more knowledge.

A literature review was conducted in order to get an initial overview of the state-of-the-art, which included searching at existing standards, legislation, and schemes. On this foundation, the suggested approach was created. On this foundation, the approach was created. The goal was to give users a realistic view of the building’s energy efficiency by comparing the conceptual design to the construction and operational stages, accounting for future needs and demands. Users will be able to evaluate the performance of their building based on this comparison. Environmental indicators will not only affect the building’s energy class but will also be offered to the user as supplementary information. The guideline for obtaining required data concerning environmental and energy indicators and providing instructions for the calculation to all interested parties is the result of this task, as described in this deliverable.

The D^EPC indicators, which show how buildings perform in terms of energy and the environment, are proposed for inclusion in the next-generation EPCs. The Level(s) approach was used to develop the D^EPC environmental indicators. It’s a useful foundation for improving environmental performance and resource usage, as well as reducing the impact of the built environment on global resources. The use of real-time data for the generation of energy indicators for EPCs contributes considerably to maximizing energy savings and achieving carbon reductions in buildings, as well as complementing SRIs, social, and economic indicators for the issuance of truly sustainable EPCs. The calculation of the energy indicators was conducted with the use of actual monitored values in the New Wing pilot building of Frederick Research Center (FRC), referring to the total power, heating, cooling, lighting, and electrical appliances of the building. The step-by-step representation of these indicators is shown in the Appendix.

Environmental and energy indicators for the next generation EPCs display energy efficiency values based on actual data consumption, as opposed to existing EPCs, which base some environmental indicators on design values and assumptions and do not include energy indicators at all. The second half of the task, which will take place in M34 – M36, will strengthen the present technique and test the methodology on a real-life example through the development of the project.

This deliverable is an outcome of Task 2.4 Analysis of cost and economic indicators for EPCs which had a goal to deliver financial indicators for the next generation EPCs. The aim of the developed set of indicators in the project is to increase user awareness by providing additional information and enhance the user-friendliness of EPCs.

An initial overview of the state-of-the-art was performed through a literature review, where existing standards, regulations, and schemes were examined. Based on that the methodology was built. The purpose was to provide users with a real-time image of the monetized performance of the building by comparing the design phase with the operational phase and including the future values. Such comparison will allow users to allocate the performance of their building. Financial indicators will not impact the energy class of the building but will be presented as additional information for the user. The outcome of this task, presented in this document, is the guideline for extracting required data concerning the financial indicators and providing instructions for the calculation.

The calculation process was first thoroughly described including the extraction of the required data from the IFC and required inputs from the user and then put into practice using the demonstration case of Frederic University. Data examination of the measurements provided an insight into the
structure of data and served as a basis for methodology modifications. Due to lack of available data (the measurements started only recently) the example of the KPI calculation was introduced using made-up whole-year values. Next, the predicted values and expected costs for building systems were calculated using the user’s input.

Finally, the results were graphically presented. Such representation will allow users to better understand their energy performance and plan their future expenses for building systems.

Financial indicators for next generation EPCs show monetary values of actual data consumption, compared to existing EPCs where financial indications are based on the design values and assumptions. Following the development of the project, the second part of the task, which will take place in from month 34 to month 36 of the project, will improve the existing approach and test the methodology on a real-life example.

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.

Within D3.4, the D^2EPC IoT framework is described in detail, expanding the description provided in the D^2EPC architecture defined in T1.4 of WP1 [1]. According to this description, the IoT framework was separated into conceptual layers describing both its hardware and software infrastructure. The physical layer contains the smart monitoring system comprising a set of IoT sensing devices and building management systems that communicate through wireless communication with the components in the interoperability layer. The interoperability layer consists of the Information Management Layer (IML) component responsible for collecting, processing, and streaming the data from the physical layer to the project's repository, where they are stored and distributed to other D^2EPC components. The IoT Gateway is the local hardware component acting as a bridge between the physical and the interoperability layer. The Gateway is capable of integrating a plethora of multiprotocol IoT devices and providing a common interface to the IML.

Within T3.1, a comprehensive list of equipment is proposed for the pilot buildings, taking into account the data requirements of the project and the infrastructure availability on site. Based on the proposed list, 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 equipment can be described as a step-by-step approach based on the requirements arising from the key performance indicators and the operational rating methodology (elicited within WG2), along with the information extracted from the pilot audits in WP5. More specifically:

- Identification of the metrics & respective measurement granularities necessary for the KPI and operational rating calculation, which helped shaping the requirements in terms of IoT infrastructure per pilot building
- Detailed and in-depth analysis of the audits on the pilot sites (performed under WP5), which allowed a complete picture of the available devices, the limitations per site, the areas to be included in the D^2EPC activities etc.; Through this information, the individual needs in IoT equipment per pilot site were highlighted.
- Based on the above, extensive testing were conducted to ensure both the effectiveness and applicability of the proposed off-the-shelf products and the interfacing with the available infrastructure whenever possible.

Initially, the second version of the deliverable dedicates a chapter on the overall dynamic metric and system operation requirements as extracted from the work conducted under WP2 and WG2. It further provides updated information on the D2EPC pilot sites along with a summary of the available infrastructure, including the assets, and existing metering/sensing equipment with the respective measuring interval and information retrieval method. D3.4 is further dedicated to the components of the IoT Equipment to be deployed on the pilot premises and describes the trials performed locally on Hypertech’s testbed towards the evaluation of the proposed IoT devices. The final chapter presents the Information Management Layer component along with its technological capabilities that address the challenges related to big data collection and analysis directly linked to the IoT domain. The definition of the IML and the IoT Equipment within the D^2EPC System Architecture that highlights the interactions between all relevant components, has already been provided in the previous version. This version is enriched with the interfaces as defined to realize the information exchange between the IML and the pilot infrastructure or other external data bases.

This document is the first version of the D^2EPC Added Value Services Suite. D4.2 provides a thorough description of the main components that comprise the Added Value Services Suite, namely, the RoadMapping Tool, the AI-driven Performance Forecasts, and the Performance Alerts and Notifications. Furthermore, it provides information about their current development status, describing the work that has been carried out up to this point (M25) in the project. The interconnection between the examined sub-modules and other core components of the D^2EPC architecture is also analysed.

In the first part of this deliverable, a literature review is presented, analysing state-of-the-art methods and best practices with regard to the three sub-modules. Some of these methods are selected and experimented towards investigating whether they present a good fit for the D^2EPC ecosystem.

The second part provides the reader with more specific information about the applied methodologies along with software-specific implementation details. The document provides information about aspects such as the required inputs and the necessary preprocessing that is applied to the collected data, as well as, the general workflow of these tools in order to achieve the desired results.

In the case of the RoadMapping Tool, the already existing building documentation from the Building Digital Twin module is leveraged to diagnose the building’s current state and strategically recommend the right renovation actions to increase the asset’s energy efficiency. The analysis is performed both in terms of the building’s envelope as well as of the installed technical systems that serve the asset’s requirements. Finally, the tool examines the use of Renewable Energy Sources to reach net zero energy consumption goals.

The operational characteristics and behaviour profiles in terms of the asset’s energy consumption and indoor conditions are examined by the AI-driven Performance Forecasts. The module relies on temporal data, namely the day of the week and the month of the year, weather data such as the daily average, maximum and minimum temperature, and historical consumption data. It becomes evident that the successful integration of these modules will be aligned with the data quality that they receive, and the techniques that will be deployed to tackle the issue of missing or corrupted data.

This report is the first version of the Extended dEPCs Applications Toolkit. D4.3 v1 delivers a detailed description of the D^2EPC toolbox that provides a series of invaluable services to the end-user. The respective modules correspond to the “Energy Performance Benchmarking” and the “Energy Performance Verification and Credibility” and are thoroughly discussed within the deliverable.
D4.3 initially presents a conceptual overview of the application’s toolkit to be integrated into the D^2EPC architecture along with the literature research which preceded the design of components. Then, the report dives into the sub-modules that constitute the two main components of the toolkit, providing insights into their overall operation and functionalities to be delivered to the end-users and other stakeholders.
Starting from the Energy Performance Benchmarking, the module comprises two separate sub-modules, the Classification and Benchmarking Tool. The Classification Tool is equipped with the appropriate modern data mining algorithms able to extract information from operational and temporal building characteristics. Its main focus is to generate distinct classes for the categorisation of the buildings under study. On the other hand, the Benchmarking Tool steps on the generated classes and materialises the benchmarking service. This service contributes to the evaluation of the building performance by establishing a set of performance criteria – built upon the comparison of buildings- to be satisfied by future EPC users.
The large number of installed devices and the huge volumes of generated data raise the need for specific applications to check the operation of IoT equipment and the quality of extracted data. For this reason, the D^2EPC Applications Toolkit includes the Energy Performance Verification & Credibility module which is equipped with the appropriate software to undertake the device monitoring and data quality assessment. The Network Monitoring Tool keeps track of the operational status of deployed devices and delivers a network representation to the end-user via a Credibility UI. Meanwhile, the Data Quality Tool performs tailored checks on the collected data to ensure their adequacy prior to their utilisation from other project components.
Beyond the components’ description, the report includes the development status of the modules and presents some validation results, part of the works conducted as of M26 of the project. Lastly, the deliverable wraps up the insights provided and concludes with what will be included in the second and final version, D4.7.

This report presents the results of Task 5.1 D^2EPC guidance for auditing and implementation activities, aiming to provide guidance for the implementation of the D^2EPC methodology. The overall goal of this report is to provide an overview of the different aspects of the D^2EPC scheme and introduce the different steps for the implementation of the D^2EPC principles. Starting with EPC calculation methodologies, an overview of the asset energy performance rating methodology has been presented based on the ISO 52000 series of standards while it has adopted several features from national asset rating calculation framework. The input parameters for the calculation have been described in detail documenting the

- Assessed object general information (Object type; Building/ space category; Climatic data);
- Thermal zones division: the spaces in a building or building unit should be grouped into thermal zones (according to their thermal characteristics), in order to proceed with the asset rating
- Analytical descriptions of the elements that comprise the building’s envelope: Depending on their visual transparency, the building elements are divided into two main categories, the “opaque and transparent” building elements. A second distinction is done according to the placement of the element on the building topology (e.g., internal, external in contact with the ambient air or external in contact with the ground etc.)
- Installed technical systems: the different categories include technical systems for heating, cooling, domestic hot water, lighting, solar thermal collectors, photovoltaics and automation and control.

Following the asset rating, the methodology for the operational energy performance rating of buildings has been described. A key value for the EPCs’ classification and issuance is the thermal energy per unit of conditioned building area (kWh/ (m2a)). Apart from this value, the following values can also be given: (a) annual energy per unit of conditioned building area (kWh/(m2a)), (b) annual electricity supply per unit of conditioned building area (kWh/(m2a)), (c) annual primary energy for the operation of the building per unit of conditioned building area (kWh/(m2a)), and (d) annual CO2 emissions due to the operation of the building per unit of conditioned area of the building (kg /(m2a)). An example of the Frederick University pilot building has been also included. In particular, the methodology proposed provides a well-defined process presenting:

- The indicators of the D^2EPC operational scheme (e.g., heating, cooling, lighting, appliances, domestic hot water, total),
- The reference values, based on which the rating will be calculated. The actual, degree-dayadjusted heat consumption and the annual real electricity consumption are used as the basis for the classification of each building on the energy label scale, instead of a reference value, which depends on building type with different demand of energy performance.
- Issuance frequency. Once issued, the operational energy dEPC is valid and should be renewed every six months according to weather normalization procedures. This allows an improved energy performance of buildings to be achieved.
- Normalization practices for operational values. The operational rating dEPC has a degree-day indicator for heating/cooling energy consumption.
- Methods of measurement of actual consumption and details (e.g. instruments, responsibilities, etc.).

The additional set of indicators to be included in the next generation EPCs, namely SRI, energy and LCA, human comfort and economic indicators have been introduced and documented. The extraction of those indicators through a BIM file has been discussed. In particular:
- The development of D^2EPC SRI assessment is based on ‘‘Method B’’ of the final SRI technical study conducted by a consortium consisting of VITO NV and Waide Strategic Efficiency and concluded in June 2020.
- The Human Comfort and Wellbeing indicators step on three pillars of indoor environmental quality i.e. the thermal comfort, the visual comfort and the indoor air quality.
- The development of the D^2EPC environmental indicators is based on the Level(s) scheme, the EU sustainability assessment for constructions outline. The operational rating scheme is used for the calculation of the energy indicators and a complete list of 25 data results, from 4 categories, is presented.
- The set of financial indicators was developed based on the literature review of wellestablished standards and schemes, aiming to translate the individual elements of buildings’ energy performance into monetary normalized values.

Finally, the major D^2EPC components that are utilised for the implementation of the D^2EPC framework have described. In particular, the D^2EPC BIM-based Digital Twin enables the unification of various forms of user-provided data with dynamic information while the WebGIS tool enables various analysis and visualisation options of the available data. The unified D^2EPC Web platform will host the presentation of all the results from the various components and sub-components, such as the EPCs, the KPIs, and the additional services. Through the web platform, the user will be able not only to adjust and configure certain components but also to request directly the execution of certain processes ad-hoc.

The technical features of the D^2EPC framework will become clearer and more explicit as the project progresses and the technical activities proceed. As a result, the next version of this report is expected to have more detailed information, with certain elements being re-evaluated and refined.

One of the most important requirements and effective features (regarding providing information to the end-user) of the Energy Performance of the Buildings Directive (EPBD) is the Energy Performance Certificate (EPC). The purpose is to increase the demand for buildings with excellent energy efficiency performance and the use of renewable sources, both in new construction and renovation. Therefore, EPCs became mandatory at the point of selling and renting or for a construction permit in the Member States of the European Union.

Several years have passed since the first publication and implementation of the EPBD in Europe. The EPBD has been adapted and amended since its first application and an adapted EPBD is on the way and will be published soon. For sure, there will be many changes regarding the requirements for buildings by 2030, 2040 and 2050 in order to decarbonise the built environment. New features and requirements as well as adaptations are going to be added to the already existing ones. This report concentrates on the implementation of a few aspects of the EPBD and its amendments until 2021. Nevertheless, new changes will remain relevant for the implementation of the project D^2EPC.

The research carried out within the project shows that some of the Member States have adapted the EPC schemes since their first implementation in order to make them user-friendly. There are different methodologies currently used to issue an EPC at the European level. In some countries, the EPC is issued based on calculated energy demand (asset rating) or on real energy consumption (operational rating). Some Member States store the EPCs in a database at national or regional level. The information available in these databases is being used for different purposes – mostly for research and quality control of the EPCs. Some countries have obligatory education and trainings for the experts issuing EPCs. In the light of the new EPBD, the qualification of the EPC issuer gains more importance since the new set of indicators as well as renovation measures for a roadmap are going to be in part of the EPC scheme.

This report not only gives an update on the implementation of some aspects of the EPBD, such as quality control of EPCs or education of the EPC issuer, but also addresses further aspects, such as Smart Readiness Indicators, market acceptance, use of smart meters, connection of the EPC database to other databases and use of digital models, which are part of the project and its outcomes. For this purpose, a questionnaire was developed for the experts in the participating countries to gain an overview on these subjects. The questions address the following issues: i) Smart Readiness Indicators; ii) use of EPCs beyond provision at the point of selling, renting or construction; iii) methods of checking the application of renovation measures; iv) use of digital models, use of EPC databases; v) education of EPC issuers; vi) use of smart meters and finally; vii) market acceptance of EPCs.

Since the engagement of stakeholders – especially for the project exploitation and usability – is crucial, different aspects of the project’s outcome for a “digital dynamic EPC” will be discussed and both advantages and opportunities for application will be determined within the workshops and meetings with relevant stakeholders (identified during the first project period). The feedback and the results of these interactions with stakeholders will feed into the work implementation of the project. The aim is to compile a recommendation report for the Next Generation of (dynamic) EPCs according to the latest version of the EPBD at the end of the project.

D6.3 EPC and Building Renovation Passport is the outcome of task 6.3 Linking EPCs with building passports and renovation roadmaps. The objective of the task was to clarify how EPCs can be integrated within the Building Renovation Passports. The aim was to identify, consolidate, and present in a meaningful way, the outcomes and experiences of D^2EPC that can potentially strengthen the development and standardization of BRP. The idea is that the new EPC results can be summarized in a document that can be used as a baseline and benchmark for the definition of renovation activities. D^2EPC’s outputs were matched with the key components of BRP and demonstrated in two case studies. To maximise the impact the generic guidelines and technical advisory were prepared to stimulate deep renovation and BRP promotion at various levels.
