Hello everyone,
A quick question for you: What do you think about the new standards for new construction and what they might mean for all of us? It seems that the requirements for new buildings are increasing significantly. Policymakers are placing more emphasis on energy efficiency and sustainability, which of course also has an impact on construction costs. This could have considerable consequences for many of us who are thinking about building a new house or purchasing a property. On one hand, it’s good that we are building in a more environmentally friendly and sustainable way, but on the other hand, this might also push property prices even higher. What are your thoughts on this? How do you think these new standards will affect the real estate market, and should we as future homeowners or buyers pay attention to anything in particular?
Looking forward to your opinions! 😉

Haus Luni30 Jul 2024 11:49I see the new standards mostly as a double-edged sword.
Energy efficiency is theoretically beneficial for protecting the environment and reducing additional costs. However, achieving insulation with a large amount of polystyrene or extruded polystyrene foam, which is considered hazardous waste, is far from ideal. Unfortunately, alternative raw materials are simply too expensive.
For a KFW 40 house with subsidies, a photovoltaic system is a must. In theory, this idea is not bad. Many small (theoretically) green energy producers could provide a solution to managing the energy crisis in the long term. Photovoltaic modules have also become much cheaper and more efficient due to higher sales volumes. However, these systems are not profitable when electricity has to be purchased at 30 cents per kWh and can only be sold for 7 cents per kWh. Most modules come from China, so both their environmental impact and manufacturing conditions for workers raise concerns. I am also genuinely curious whether the modules will last 20 to 30 years in operation. If not, I am quite sure warranty claims will no longer be possible at that time because the company will likely no longer exist.
With most new standards, I feel that the government simply hopes the market will somehow regulate itself and find a solution. However, this does not really work well or only happens at the expense of the citizens. Many regulations conflict with each other, and in most cases, foreign countries benefit more than the country itself.
The willingness to perform personal labor has significantly decreased overall. However, it must also be said that legislation and many manufacturers are increasingly making it more difficult to do things independently. There are far too many regulations and permits required that did not exist in the past. Additionally, the "fear" of doing things yourself is strongly encouraged. It seems that you only hear and read that everything should be done by a professional company because it is considered highly critical, difficult, or dangerous to do it yourself.

I mostly see the new standards as a double-edged sword. They primarily apply to multi-family residential buildings. In that case, the sword is one-sided—when, out of fear of the technical regulations, 137 electrical outlets per apartment are “required” or floor slabs between stories must be at least 30cm (12 inches) thick.
Just as an example from the 2022 planning phase, when comparing how new floor slabs are constructed across Europe—all current recognized technical standards… (depending on the country)
This is exactly why there is a need to reduce the excessive regulations, strict adherence to DIN standards, and inflexible compliance with recognized rules of technology, without significantly compromising usability. The goal: more new housing construction at reasonable costs.
And many aspects of building type e, which is the focus here, achieve this. It also applies, for example, to vertical extensions, which are significantly eased.

Haus Luni30 Jul 2024 12:56I can easily imagine how something like this happens.
I’m not an active designer, but I am a mechanical engineering technician and have studied industrial engineering. During my studies, we had to calculate a shaft that needed to withstand 2 tons. First, you identify the weakest point and calculate the required diameter. That was around 12mm (0.5 inches). Then comes the safety factor! If human safety could be at risk, the safety factor is 4.5. This means 12mm (0.5 inches) x 4.5 = 56.25mm (2.2 inches). According to regulations, this diameter must then be selected.
I assume structural engineers have similar regulations.

thangorodrim9 Sep 2024 23:01A group in this forum has identified the exaggerated demands of homeowners as the reason why building seems too expensive for many. People no longer want to build without walk-in closets, KNX (home automation systems), and double garages. A question to this group: Why, then, have large housing companies like Vonovia stopped or reduced their residential construction and are waiting for better times (which, according to consensus here in the forum, will never come)?
Quote (August 1, 2024):
Why doesn’t Vonovia simply build smaller and without KNX?
Quote (August 1, 2024):
Vonovia emphasizes scaling up development as soon as the conditions for new construction allow reasonable costs and affordable rents again.
