RENOVATION WAVE & NEXT-GENERATION EPC

▪ Digitalisation is the only way to get the "renovation wave" done. EPC should be a driver.

▪ Compliance, transparency & reliability is must to gain trust

▪ Future EPC: digital (building passport, BIM, measured data), comprehensive/holistic (incl. IEQ and comfort) indicating in-use performance

Enhance EPC assessment, certification, and verification, regarding

(1) the quality and cross-EU convergence of Energy Performance Certificate (EPC) schemes, including building assessment and EPC issuance, design, verification, and use;

(2) the link between EPCs and deep renovation.

• QualDeEPC will stimulate such changes by

(1) intensive dialogue involving the important stakeholders at all levels from the

very beginning

(2) implementing consensus elements as far as possible and

(3) disseminating its findings among the relevant target audiences in Europe

COMMON CHALLENGES

Jonathan Volt, Project Manager, BPIE

• Diverse EPC approaches across the EU

• Questionable reliability and quality

• Limited understanding of the EPCs

• EPC data – a missed opportunity?

• Renovation recommendations –preaching to deaf ears?

Common challenges:

Diverse EPC approaches across the EU Challenge (1):

• Asset vs operational ratings• EPC software• Data gathering• Methodology• Calculation/weighting

Diverse EPC approaches across the EU Challenge (1):

• Asset vs operational ratings• EPC software• Data gathering• Methodology• Calculation/weighting

There are more than 30 calculation methodologies in the EU!

Diverse EPC approaches across the EU Challenge (1):

Many options to tailor to national/regional contexts:

Questionable reliability and quality

Source: X-tendo

Austria: “Acceptance from thetenant and buyer point of view, lackof understanding on the seller andrenter side”.Flanders, Belgium: “EPC is generallywell accepted. EPC for newlyconstructed and renovatedbuildings is linked to theapplication of the building permitand is legally mandatory.”Poland: “General opinion is thatEPCs have little value. The formand information on the EPCs areunclear for the final user.”Romania: “The content of EPCs,with the exception of the coloredscales, is not connected to thecommon understanding of whatenergy consumptions are.

Roadmap

Strategy

48

1. Improving the renovation recommendations of EPCs towards deep energy renovation• Development need: concrete set of recommendations, focus residential

2. Online tool for comparing recommendations of EPCs to deep energy renovation recommendations (residential buildings)• Development need: master version of the tool in English, adapted to national

situation and language (new tool or improving existing tool)

3. Creating Deep Renovation Network Platforms (= One-stop shops plus networking of supply-side actors; online platform or physical hub)• Development need: overall concept;

decision if new Deep Renovation Network Platform has to be developed or cooperation with an existing one is possible

Priorities for the development of next generation EPC schemes (1)

49

4. Regular mandatory EPC assessor training on assessment and recommendations required for certification and registry• Development need: policy proposal on mandatory periodic training, a

curriculum for regular mandatory training, training content; focus on renovation recommendations

5. High user-friendliness of the EPC • Development need: identification of information most important for users

and how to present it; including recommendations and links to further information

6. Voluntary/mandatory advertising guidelines for EPCs and7. Controlling and enforcing the mandatory use of EPCs in real

estate advertisements• Development need: concrete proposal for advertising guidelines and for

routines of control and enforcement

Priorities for the development ofnext generation EPC schemes (2)
