A buddy from IT is thinking about taking over and renovating his parental home. Unfortunately, the density of energy consultants with a good website is alarmingly low. And if they have top-notch sites, I'm almost skeptical.... His mantra is that he doesn't even approach anyone with a bad internet presence. I told him, then my house wouldn't exist. Only the general contractor had a homepage that went beyond the imprint and a displayed phone number.

With us, everything was planned in advance by the energy consultant and the trades have to adhere to that. We also do a lot of work ourselves and arrange individual contracts.
It is also not relevant exactly what is installed (for example, no specific heat pump or air conditioning) because the values are kept very general. We have to balance our air conditioning with the photovoltaic system.
Much more detailed for us was the entire construction of the wall, floor slab, roof, etc.
The energy consultant calculated the building components based on my wishes (for example, I only wanted wood fiber insulation for the roof and walls or glass foam gravel under the floor slab) and this was all determined. With the data, I went to the companies and got my offer based on the building components.
