What matters most when renovating a building?

Your answers are converted into numerical weights used to compare renovation options — balancing energy, costs, comfort and safety. There are no right or wrong answers. Estimated time: 15–25 minutes.

Responses are analysed in aggregated form per stakeholder group and country. Name and contact details are optional.

The reference building — please keep it in mind throughout

Please answer all questions with the following typical building in mind — it represents the kind of building this methodology targets in your country:

A multi-family residential building built between 1960 and 1975, typical of the national housing stock: 3–5 storeys with 10–30 dwellings, an uninsulated or poorly insulated façade and roof, windows only partly replaced, central heating using fossil fuel, energy class D–E. No major renovation has been carried out so far. The building was designed before modern seismic codes and stands in an area of seismic hazard typical of your country.

The renovation options under consideration range from a medium energy renovation (e.g. windows, roof, heating system) through a deep energy renovation (full envelope + systems, towards a nearly zero-energy standard), up to a deep renovation combined with seismic strengthening.

How to answer the comparison questions

Each question shows two criteria, A (left) and B (right). Pick one value per row: the middle 1 means both are equally important; values towards a side mean that side is more important — 3 moderately, 5 strongly, 7 very strongly, 9 extremely.

Try to be consistent: if A matters more than B, and B more than C, then A should also matter more than C. The form checks your consistency as you answer and will point out where to have a second look.

Part F — What encourages and what blocks renovation?

F1. How strongly would each of the following encourage you (or the owners you represent) to renovate? (1 = not at all, 5 = very strongly)

F2. How strongly does each of the following discourage or block renovation in practice? (1 = not at all, 5 = very strongly)

Part G — Your renovation situation

G1. Your relation to buildings like the reference building above G2. Has your own building undergone a major renovation in the last 10 years? G3. If you were shown a clear renovation plan with costs, savings and financing options, how likely would you be to invest within the next 5 years? (1 = very unlikely, 5 = very likely)

G4. Familiarity with the Energy Performance Certificate (1–5)

G5. Familiarity with the Building Renovation Passport concept (1–5)

G6. Would a step-by-step renovation roadmap help you decide on renovation?

Part I — Anything to add?

Is an important aspect of sustainable renovation missing? Any comment on the questions?
