ᐅ Which type of façade is better?

Hello,

We are currently trying to decide which type of facade construction is preferable. The two facade options are as follows. It is assumed that the costs are the same, and any gains or losses in space can be neglected. The focus is solely on the advantages and disadvantages of the facade construction itself.

1.) 17.5 cm (7 inches) Poroton, mineral wool insulation, facing bricks. Total construction depth 44 cm (17 inches)

2.) 36.5 cm (14 inches) Poroton, brick slips. Total construction depth approximately 38.5 cm (15 inches)

In both cases, the result is a KfW 55 standard.
Is it possible to determine which construction is more valuable? Please explain.

Best regards,
Ralf

As I mentioned before, I first researched different types of façades and various bricks, and then I found a developer that fits those choices.

That’s the “atypical” point in your story: most people who want to compare two wall constructions come from a different situation – meaning the builder is already decided, and they only offer either red-white or white-red patterned options.

It’s nice to read that your situation is different here.

I think both options are basically good, so that’s why both are suitable for me. [...] The developer is generally quite versatile and also offers other solutions.

That also sounds good. Then, as mentioned, choose the option from your shortlist that the planners and builders have more experience with.

With that, I’ll leave it here for now – I’m looking forward to when and what you will tell us here about the house you’re planning to build. You asked about design software a few months ago, after all.

Funny that you still remember my question.
In the end, I used Sweet Home 3D, which was sufficient.

Indeed, some builders were quite surprised at how much thought we had already put into it. I also got the impression that they have an easier time selling their houses to many customers because those customers simply don’t care about the details...

For us, it ended up being a fairly standard family home, except the knee wall is a bit higher. Unfortunately, we are not allowed to build something significantly different, like a Tuscan-style villa that we initially wanted, because we have to conform to the surrounding development. That consists mainly of family houses with pitched roofs and bungalows.
Our concept, however, is more future-oriented—we decided to avoid gas and instead use an air-to-water heat pump. Of course, we will also install a mechanical ventilation system with heat recovery. On the roof, we will only place photovoltaic panels, no thermal collectors...

No, just check the post history, you know? I don’t have that completely memorized without support.

I assume you mean the "knee wall." In some regions, the terms get mixed up, and people call both the knee wall and the dwarf wall the same. Actually, the knee wall (raising the eaves purlins) is what you use to avoid the dwarf wall (internal low wall).

In a few years, you’ll probably be glad about that. Platform shoes and bell-bottoms didn’t stay in fashion forever; houses with flared skirts (and those with bright red painted projections) will go the same way. Glass bricks were once trendy. Or floor plans with 45° chamfered corners.

Please feel free to explain in more detail where exactly you differentiate between those.

One system generates electricity, the other produces hot water (photovoltaics vs. solar thermal)

I am aware that solar energy can be converted into electricity or heat, but the original poster was referring to "these collectors." These have existed since the time when gas heating was still common; and whatever they fed into the power grid was certainly not hot water.

While collectors can be optimized for either purpose, I would not decide on the roof what to use the solar energy for. Energy preservation is key – the longer it is stored in a universal form, the more practical it becomes.

You know exactly what is meant. Why make a fuss?
