Our construction supervisor (BU) is very honest, and we, as well as others, trust him a lot.
However, he is not a fan of ventilation systems.
Here are the prices he quoted. Are there
1. Solutions that are more integrated into the wall or similar, to avoid additional height increases, and
2. Is the price reasonable?
Total area is 187 sqm (2013 sq ft), including about 40 sqm (430 sq ft) of an extension. The rest is spread over two levels in a town villa style.
There is a ceiling opening of about 9 sqm (97 sq ft) to the first floor, which is not included in the 187 sqm (2013 sq ft).
Attached is the text from the BU.
Pluggit Avent fresh air unit with heat recovery included.
Aluminum cross counterflow heat exchanger
Including air ducts, supply and exhaust air outlets, silencers, distributor, cover grilles in standard white plastic, supply and install 14,192.58 €
Blower door test mandatory when installing ventilation system 476.00 €
Increase of total floor construction height from 14 cm (5.5 inches) to 18 cm (7 inches) on the upper floor
By adding 3 cm (1.2 inches) more styrofoam insulation 2,988.97 €
Enthalpy exchanger and summer bypass
No costs yet

HeimatBauer11 Dec 2023 13:33The original poster is free to share their detailed construction specifications and added items here and ask where it might make sense to cut costs. As I mentioned before, I saved a five-figure amount just on the bathrooms alone. And so on.
I have become skeptical about motorized roller shutters. For budget reasons, I only installed four of them, and looking back, that was my biggest mistake. At least all the ones on the south side should have been motorized, if only to automate them. Not to mention thermal bridging and the issues with manual operation (because the kids like to slam the shutters up for fun).

In return, everyone rushes to the gym because they don’t get enough physical activity. You don’t seriously want to claim that airing the house once a day burns off the daily portion of cookies (with chocolate!)? You definitely need to do a lot more than that. And we don’t chop our own wood anymore just because it provides more exercise.
And yes, price is a factor. On the other hand, I only partially accept that argument, because even well-known budget builders like Danwood and Town & Country have been including ventilation systems as a standard feature for some time. So the costs are skyrocketing elsewhere.

Yes, but honestly: one minute isn’t really airing out, it’s just opening the window.I never claimed otherwise. 30 seconds to open, then you can do something else, and after 15 minutes or however long, you close the windows again in 30 seconds.
If you allow 5 minutes per day for just opening and closing, that’s a generous estimate.
Of course, if you always have to clear plants off the window first, that will naturally take longer.

That sounds cute, and you can probably laugh about it, but this is exactly what you want to avoid. Not that the child chats, but that energy escapes uncontrolled from the house and you need to reheat because of it.Wouldn’t they do the same with a mechanical ventilation system? That would just mean additional air exchange, which is already factored into our calculations 🙂
Of course, we also remind people, but I can take it much more relaxed than someone with a ventilation system.
I already mentioned my heating electricity consumption... so what savings could the ventilation system realistically provide?

That was my argument regarding the lack of electrical operation of my roller shutters. You have to weigh what extras you add on top or what is built as standard. But I do understand your final point about construction costs: everyone complains, but builds nice-to-have features worth 50,000€ when you include the additional square meters for pantry, dressing room, and kids’ bathroom.We consciously chose to build modestly and without frills at the time, and we managed to stay within prices that were already considered unrealistic here on the forum. On the other hand, we made many extra repayments. With each extra repayment, our total debt decreased by more than double the repayment amount. We will be done paying off in 1.5 years. We never wanted to work just to pay for the house.

HeimatBauer11 Dec 2023 14:10Extra repayments can be useful, but they are not always the best option – if I currently have extra money, I prefer to invest it at 4% rather than save 1% in interest.

What significant savings should a ventilation system really provide?The question is (because a ventilation system doesn’t replace heating): how much electricity does a ventilation system consume?Musketier schrieb:

Extra repayments can make sense, but don’t have to—if I currently have spare money, I’d rather invest it at 4% than save 1% interest by paying down the mortgage.We’ve already discussed this. It doesn’t work because you don’t get those interest rates right from the start or continuously. Look, when @Musketier and I built, those rates didn’t exist. Now you might get them for 3 months as a new customer, possibly for a year. But that’s just a drop in the bucket. And for those who see that you no longer pay interest on money you’ve repaid early, it’s a bad deal. This is always misunderstood. You can’t get financially healthy by paying interest on money you still owe.H
