Energy renovation
Focus on energy and economy (quantitative values)
- Improve energy performance of the building
- Economically interesting
Qualitative aspects are often seen as secondary benefits

In 2010, we had in the European Union:
• < 1% of the building stock renovated yearly
• ~95% were minor or conventional energy renovations
• ~5% were deep energy renovations
Until 2050, in order to comply with the EU goals, we need:
• ~2,5% of the building stock renovated yearly
• ~90% of deep to nearly zero energy renovations
• ~10% of minor or conventional energy renovations
Potential in the energy renovation sector

Barriers to energy renovation
– Politico-economic barriers
– Technical barriers
– Behavioural barriers
9
www.cena1212.wordpress.com
Politico-economic barriers are being addressed by policy makers and market developers.
Most technical barriers are being addressed by the building industry.
Behavioural barriers directly impact building owners, occupants and professionals.
![Page 10: Den Integrerede Renovering Proces (IRP) · –Can we get this modern look in “Scenario 2”? –What would be the cost of integrating the finishing materials of “Scenario 3”](https://reader033.vdocuments.pub/reader033/viewer/2022041516/5e2b5cdc6b35041522599f40/html5/thumbnails/10.jpg)
Examples of behavioural barriers
• Limited knowledge
• Lack of interest
• Lack of guidance
• Lack of confidence
• Lack of social and emotional understanding
10
![Page 11: Den Integrerede Renovering Proces (IRP) · –Can we get this modern look in “Scenario 2”? –What would be the cost of integrating the finishing materials of “Scenario 3”](https://reader033.vdocuments.pub/reader033/viewer/2022041516/5e2b5cdc6b35041522599f40/html5/thumbnails/11.jpg)
Hypotheses
11
Could a more holistic methodology be the key in overcoming behavioural barriers to high performance home renovation? Could we integrate the home occupants in the centre of the decision-making process using an adapted language?
![Page 12: Den Integrerede Renovering Proces (IRP) · –Can we get this modern look in “Scenario 2”? –What would be the cost of integrating the finishing materials of “Scenario 3”](https://reader033.vdocuments.pub/reader033/viewer/2022041516/5e2b5cdc6b35041522599f40/html5/thumbnails/12.jpg)
Overcoming barriers to energy renovation
• Need for contributions from all parties • Need for interdisciplinary collaborations
12
![Page 13: Den Integrerede Renovering Proces (IRP) · –Can we get this modern look in “Scenario 2”? –What would be the cost of integrating the finishing materials of “Scenario 3”](https://reader033.vdocuments.pub/reader033/viewer/2022041516/5e2b5cdc6b35041522599f40/html5/thumbnails/13.jpg)
The concept of sustainable renovation
• More holistic approach
• Better integrate building occupants
• One-step and stepwise renovation
13
More focus on immaterial aspects of sustainability
![Page 14: Den Integrerede Renovering Proces (IRP) · –Can we get this modern look in “Scenario 2”? –What would be the cost of integrating the finishing materials of “Scenario 3”](https://reader033.vdocuments.pub/reader033/viewer/2022041516/5e2b5cdc6b35041522599f40/html5/thumbnails/14.jpg)
Decision-making problem
What is the best renovation scenario?
– Non-expert decision makers
– Homeowners very involved
– Homeowners very emotional
– Small project with few resources
14
![Page 15: Den Integrerede Renovering Proces (IRP) · –Can we get this modern look in “Scenario 2”? –What would be the cost of integrating the finishing materials of “Scenario 3”](https://reader033.vdocuments.pub/reader033/viewer/2022041516/5e2b5cdc6b35041522599f40/html5/thumbnails/15.jpg)
Decision support methods applicable to sustainable renovation
SEMI-STRUCTURED PROBLEM
Selection of the best renovation scenario
CRITERIA Multiple conflicting
Both qualitative and quantitative Candidate to be solved by multi-criteria decision-making
methods (MCDM)
15
![Page 16: Den Integrerede Renovering Proces (IRP) · –Can we get this modern look in “Scenario 2”? –What would be the cost of integrating the finishing materials of “Scenario 3”](https://reader033.vdocuments.pub/reader033/viewer/2022041516/5e2b5cdc6b35041522599f40/html5/thumbnails/16.jpg)
What are multi-criteria decision-making methods used for?
• Purpose: Identify the most appropriate solution out of a set of
alternatives • Specificity: Alternatives are characterised by multiple and possibly
conflicting attributes. • Categories: Support or optimisation
– Organise information for decision situations – Add structure to decisions – Interact between decision makers – Expand the decision maker's horizons

The Integrated Renovation Process (IRP)
![Page 18: Den Integrerede Renovering Proces (IRP) · –Can we get this modern look in “Scenario 2”? –What would be the cost of integrating the finishing materials of “Scenario 3”](https://reader033.vdocuments.pub/reader033/viewer/2022041516/5e2b5cdc6b35041522599f40/html5/thumbnails/18.jpg)
The Integrated Renovation Process
18
• Decision support tool
• Adapted to non-expert decision makers
• User customised
• Makes benefits from quality renovations clear and assessable
• Encourage communication between project stakeholders
• Encourage knowledge discovering
![Page 19: Den Integrerede Renovering Proces (IRP) · –Can we get this modern look in “Scenario 2”? –What would be the cost of integrating the finishing materials of “Scenario 3”](https://reader033.vdocuments.pub/reader033/viewer/2022041516/5e2b5cdc6b35041522599f40/html5/thumbnails/19.jpg)
The Integrated Renovation Process
Iterative process in 3 phases:
• Study of homeowners’ values and house profiling
• Generation and evaluation of renovation strategies
• Synthesis & selection of the best strategy
19
![Page 20: Den Integrerede Renovering Proces (IRP) · –Can we get this modern look in “Scenario 2”? –What would be the cost of integrating the finishing materials of “Scenario 3”](https://reader033.vdocuments.pub/reader033/viewer/2022041516/5e2b5cdc6b35041522599f40/html5/thumbnails/20.jpg)
Study of homeowners’ values and house profiling
20
• Semi-open questions
– Functionality
– Aesthetics
– Usability
– Safety
– Economy
– Indoor environment
– Artistic values
– Degradation & obsolescence
– Etc.

Evaluation of prospective buildings
• Open dialogue
– What type of spatial configurations can I get in “Scenario 2”?
– Could we insert the demolition of the inner walls in “Scenario 1”?
– Can we get this modern look in “Scenario 2”?
– What would be the cost of integrating the finishing materials of
“Scenario 3” in “Scenario 2”?

Konklusioner
• Hjemme-coaching: HJEM, ikke HUS!
• Husejerne:
• Var mere informerede og mere interesserede
• Følte i kontrol samtidig med at beslutte
• De forstod og fornemmede de mange fordele
• De fandt sprog veltilpasset
• De valgte den bedste renovering strategi ifølge dem
• Flere case undersøgelser er stadig nødvendige for at teste
værktøjet…
