1. Why a renovation does not begin with works
Three reasons, all leading to the same conclusion. Support funds not the works but the result, and what matters is whether the building's energy class improves, as covered by the article on the logic of the support. The result is measured against the initial situation, so the initial situation must be known first. And some works may already have been done, which limits later options, as covered by the article on works already done.
Beginning from a list of works is therefore the wrong end. The right end is the building's present condition, in energy terms, in technical terms and in terms of the register data.
2. Three things that must be known beforehand
Each answers a different question, and the third is the most often left aside. It concerns the technical condition.
| What to know | What it answers |
|---|---|
| The building's current energy class | the baseline for measuring the result |
| Whether register data match reality | the precondition for applying |
| Technical condition | what actually needs doing |
The third is left aside because it is not directly tied to the support. What is eligible is not, however, the same as what is necessary: a leaking roof has to be repaired whether or not it raises the energy class.
3. What the baseline decides
Four things depend on the current class, and the first may end the exercise altogether. The class sets the class gain required.
Whether support is available at all, since according to professional sources it cannot be applied for where the building already has the best possible class. How large a gain is required, that is class C for full reconstruction and at least a one-class gain for partial. What volume of work that gain requires. And whether the full or the partial route is realistic, as covered by the article on the two routes.
None of these questions can be answered without the baseline, and commissioning a design before it risks a solution that does not meet the conditions. The baseline therefore comes first.
4. In what order to proceed
Five steps whose order saves money, and the fourth decides the programme. Reversing the order costs money.
| # | Step |
|---|---|
| 1 | Check the building register data (register data) |
| 2 | Establish the current energy class |
| 3 | Assess the technical condition (audits) |
| 4 | Check the support conditions and the position of the round |
| 5 | Only then commission the design |
The fourth step matters particularly because rounds open and close cyclically, as covered by the article on the rounds. Preparation must be ready when a round opens.
5. What happens when the order is wrong
Three typical consequences, and the second is the most frequent. It concerns redoing the design.
| Consequence | When it appears |
|---|---|
| The design is commissioned but does not meet the support conditions | at application, and the design has to be redone |
| The register data are wrong | the application is inadmissible until corrected |
| Works are partly done | this limits the type of support available |
The second is also the most easily avoided, since register data are not looked at until they are needed. Correcting them takes time, and that time does not exist once a round is already open.
Summary and four practical rules
A renovation begins not with works but with the building's present condition, because support funds a result and the result is measured against the initial situation. Before the design one must know the current energy class, whether the register data match reality, and the technical condition, of which the last is the most often left aside even though what is eligible is not the same as what is necessary. The order of the five steps saves money, and of the three consequences of getting it wrong the most frequent is discovering wrong register data when there is no time left to correct them.
Four rules: check the register data before anything else. Establish the class before commissioning a design. Assess the technical condition, including works the support does not cover. Check the position of the round before commissioning the design, not after.
