We built our first house in 1997, installing a gas condensing boiler at the time. We used Ytong blocks, installed double-glazed windows, and had standard insulation under the roof, with a living area of about 180m² (1,938 sq ft). We never had any issues with ventilation or damp walls, and the heating system has worked without problems to this day, consuming around 15,000 kWh of gas per year.
Since the kids have been out of the house for years, we decided to sell it and build a new one in a bungalow style, meaning everything on one level. Apart from the significantly increased construction costs since 1997, we are also dealing with the question of the energy saving regulations.
We plan to have a timber frame house built by the local carpentry business. We have known our preferred floor plan for a long time but struggle with all the energy saving regulation requirements. The rules in this regulation must have been decided by someone not in their right mind. Just yesterday, there was even an article on the T-Online website stating that the KfW allegedly keeps studies secret, which prove that KfW standards are disproportionate to the enormous investment costs and basically uneconomical.
We have held this opinion for a long time. We would like to install just a gas condensing boiler with a stove, plus a controlled residential ventilation system with heat recovery. My builder says this is not possible; at least a solar system must be included; otherwise, we won’t meet the requirements of the energy saving regulation.
Okay, that may be true. But is it actually mandatory to build according to this energy saving regulation? Who enforces this? The local building authority? We asked about this, and the head of the building authority replied that he is not aware of this regulation, that it doesn’t exist, and that no one can be forced to follow such rules—it would be like communism (...a fair and accurate observation :cool 🙂.
So what actually happens if you don’t build according to the energy saving regulation?
Thank you in advance for your answers.

As I said, my focus is on potential self-sufficiency, a geothermal heat pump combined with a properly sized solar system and a home battery. I would keep the stove as a backup just in case and at the same time start planting my own little forest.Building self-sufficiency on fossil fuels is contradictory. It might still be manageable for the next 5-6 years, although I strongly doubt gas will become cheaper. In 20-30 years, it can only work well if enough people have already changed their approach.
My dream house:
geothermal heat pump, properly sized solar system, home battery, electric car. The fact that I won’t have all of this quickly, but rather one step at a time, is only a matter of money, not willingness.
Gas and oil (diesel) are only temporary solutions for me...
