Hybrid 4th Plenary meeting in Thessaloniki

Mar 14, 2022

After a year and a half of online calls, we were finally able to organize a hybrid meeting! On 8th and 9th March, we gathered in Thessaloniki, Greece for our 4th plenary meeting, where we discussed the progress of the project and defined our next steps.

On Tuesday morning we met on the premises of CERTH and connected with the rest of the partners who were not able to attend the meeting in person. We started with Project Management, where CERTH presented the overall status of the project and went through the actions and pending activities from the previous time. We continued with the WP2 and individual presentation of each of the KPIs, namely the Smart Readiness Indicators, the Human-comfort and wellbeing indicators, the Energy Performance & LCA indicators and the Cost and Economic indicators, presented by CLEO, HYP, FRC and DEMO respectively. We concluded the WP2 with the presentation of the D^2EPC Information model, by KTU. The progress on WP3 was presented by HYP, GSH and CERTH where they informed us about their findings on the IoT and BMS interfaces to extract energy related data, on the Development of a GIS scheme and Building digital twins for EPCs issuance. Further on we discussed the Building Performance Module, the Added value service suite and the Extended dEPC applications toolkit, which are tasks within WP4 and were presented by SEC, CERTH and HYP respectively. We concluded our meeting with the workshop on Asset and Operational Calculation Methodology and Digital Platform. Taking the advantage of being in Thessaloniki in person, we completed the day with a lovely dinner in the city centre.

The next day we were introduced to the D^2EPC guidance for auditing and implementation, the Case studies preparation and planning and the Demonstration and validation of NG dynamic EPC scheme. Those were presented by the task leaders within WP5, SGS, CERTH and CLEO respectively. Partners ASI and AEA informed us regarding the progress on the Updating of current standards towards dynamic EPCs and the Linking NG EPC with integrated national/regional certification schemes & choices. After the coffee break, we discussed the work within WP7, namely the Publicity and dissemination policy, planning and review, the Communication & dissemination activities & material, the Contribution to standardization activities and the Exploitation activities, IPR management and post-project sustainability. To conclude the day and the plenary meeting itself, we visited the CERTH's Smart House, which is one of the demonstration cases of the D^2EPC project.

Our hybrid meeting was a valuable experience as we were able to meet some of the partners in person for the first time. Such opportunities certainly strengthen the collaboration, and we hope we will soon be able to gather again.

The Working Group 2 met this Month

Sep 28, 2021

In the development of the D^2EPC project, as a part of T5.1 activities for auditing and guidance for D^2EPC implementation, two working groups have been formulated: Working Group 1 (WG1) on the Asset Rating of Energy Performance of Buildings in Europe and Working Group 2 (WG2) on the Operational Rating of Energy Performance of Buildings in Europe.

The aim of working groups includes the development and delivery of a tool dedicated to the asset energy performance rating of buildings based on EPBD standards (WG1), as well as the development and delivery of a methodology for the operational energy performance ratings of buildings (WG2).

Both groups have been working on their roles, and WG2 met on 8th September in order to discuss the content of the deliverable and organise the next steps.

Paris Fokaides (FRC) as a host of the meeting presented the progress of work implemented so far, the outcomes of WG 2 and initiated the discussion on how the WG could proceed from this point on. They highlighted the connection that exists between the WG2 and the needs of T5.1 as well as the content of WP2. The collection of primary material on operational rating (OR) methodologies in the EU Member States was debated, and the update of partners' input on the Member States using the OR methodology was discussed as well. They drafted the first conclusions and proposed a first version of the operational scheme.
 
The next steps for this WG are:
