Innovation actions reinforcing and complementing the current building energy performance schemes

Jun 01, 2021

​With the Renovation Wave Strategy, the European Commission aims to at least double renovation rates in the next ten years and make sure renovations lead to higher energy and resource efficiency. For supporting this overarching aim the European Commission plans to further improve the EU Energy Performance of Buildings Directive (EPBD), reinforcing the role of Energy Performance Certificates (EPCs). In favour of the evolution of EPC schemes, the four ongoing Horizon 2020 Innovation Actions for the Next Generation EPCs, including D^2EPC, participated on 19.05.2021 in a lively and informative panel discussion moderated by EuroACE and hosted in the BUILD UP portal, sharing insights on "What is needed to strengthen the information role of EPCs?", "What is needed to improve the quality of EPC?", "What is needed to improve the coverage of EPC?".

2nd Plenary meeting

Apr 21, 2021

The consortium of D^2EPC had a two-day online 2nd Plenary meeting that took place on 21st and 22nd April 2021. Meeting was led by Project coordinator CERTH. The main purpose of the meeting was to update each other on the progress of our work, discuss issues and set goals for the future. We started with work progress of WP1, where all the first parts of the tasks are already completed. After coffee break we continued with WP2 which has recently started. We had a discussion regarding all the open issues and concluded with a workshop about the Architecture Consensus. On the second day we were introduced with the progress of tasks in WP3, WP5 and WP7. It was indeed beneficial to have the opportunity to groupthink, review, debate and consult with all the partners and share our ideas. We concluded the two-day meeting with a workshop on EPC calculation methodology for asset and operation rating. It was great seeing you all!

Partners involved in WP2 have held an internal workshop

Apr 15, 2021

The key point of the workshop that took place on 15th April 12:00-13:30 and was led by KTU was to present an overview of the WP2 "Development of the Operational Framework for dEPC Schemes". We discussed the KPIs, tasks progress, working plans and the interactions between the tasks.

This WP2 which started in M6 and will last throughout the life of the project, has the following objectives:

  • To analyze and define a set of indicators to be included in the next generation EPCs, including SRI, LCA and economic indicators and taking into account user driven models (thermal/vision comfort, occupancy).
  • To deliver the system's information model to optimally support information flow among the various components.
  • To deliver the necessary requirements and steps for ensuring a common way for auditing and implementation.

Each of the task leaders of this work package have highlighted the most important aspects of the tasks and the progress made so far.

T2.1: Smart Readiness indicators Analysis for EPCs, led by CLEO, the objective is to establish the framework and scope of SRIs integration in the dynamic EPC scheme.

T2.2: Human-comfort and wellbeing Indicators Elicitation, led by HYP, the objective is to adapt, configure algorithms and models for the definition and extraction of several profiles that impact the overall dynamic building performance mainly from the user's comfort and wellbeing point of view.

T2.3: Energy performance & LCA Indicators Analysis for EPCs, led by FRC, the objective is to propose additional indicators, which demonstrate the environmental performance of buildings, for their introduction in the next-generation EPCs. The idea is to assess the existing indicators and try to justify them to be incorporated in D2EPC.

T2.4: Analysis of cost and economic indicators for EPCs, led by DEMO, the objective is to propose additional indicators, which will enable the financial assessment of buildings energy upgrade measures. This task has not started yet, it will start on the M10, and the steps to be realized include the documentation of the economic indicators which may be employed in EPCs.

To conclude KTU leader of T2.5: D^2EPC Information Model has presented the information flow that will lead to the extension of the current standards/protocols used for certificate issuance including all the new features proposed by the D^2EPC framework, and the additional indicators delivered under T2.1-T2.4.

D^2EPC project for next generation EPCs

Oct 23, 2020

The H2020 project D^2EPC aspires to set the grounds for the next generation dynamic Energy Performance Certificates (EPCs). The aim is to cause energy-efficient behavioral change and stimulate smart buildings. The D^2EPC digital platform will enable the issuance of next generation EPCs on a regular basis and will be armored with additional services.

On September 10th and 11st 2020, the D^2EPC project 'Next-generation Dynamic Digital EPCs for Enhanced Quality and User Awareness' held its online kick-off meeting. This project has received funding from the European Union's Horizon 2020 Research & Innovation programme under Grant Agreement No 892984. It is coordinated by Dr Dimosthenis Ioannidis representing CERTH, Centre for Research & Technology Hellas, one of the leading research centres in Greece with important scientific and technological achievements.

Digital twin BIM

D^2EPC aspires to set the grounds for the next generation dynamic Energy Performance Certificates (EPCs). The proposed framework engages actual measured data coming from smart devices and introduces a set of novel and user-friendly indicators. For this we make use of 6D Level 3 BIM for producing a building's digital twin representation. The proposed indicators for smart-readiness, sustainability, environmental, human comfort and financial aspects will make EPCs a realistic, accurate and comprehensive information source that can induce energy efficient behavioural change and stimulate towards smart buildings. The D^2EPC digital platform will enable the issuance of next generation EPCs on a regular basis and will be armored with additional services. The project will last 3 years and will conclude in August 2023.
