Structured review of your documents and assumptions.

3. Analysis

Comparison of options based on costs and impact.

Prefer to describe your case first?
You can send a structured request instead.

Send a written inquiry

I review each request individually and get back to you.

This is useful if you are facing a concrete renovation decision
and want to compare different options before committing.

Typical cases include:

heating system replacement
insulation vs. system upgrade
partial vs. full renovation
evaluating investment impact

If you are still at a very early idea stage, a short initial call is usually sufficient.

You receive a structured comparison of relevant options, including:

investment costs
expected financial impact
key assumptions and uncertainties

The result is not a recommendation in the sense of “do this”,
but a transparent basis that allows you to make your own decision.

The process is straightforward:

Short initial call (free, ~15 minutes)
Structured data collection
Analysis of relevant options
Clear presentation of results

You stay in control at every step — no obligations beyond the agreed scope.
