ᐅ Technical room in the attic, issues with soundproofing?

External technical building

I should have done the same in our case. Unfortunately, I realized this too late.

I find the idea of the external building appealing; I would need to check if it is feasible in terms of space.

We have an insulated wooden floor ceiling.
On top of it stands a 300-liter (79 gallons) hot water tank.
The ventilation system and gas heating are also located in the attic. These are mounted on a wall made of tongue-and-groove boards, which I built between two roof beams.
We have now been living in the house for two weeks, and you can’t hear a thing! Even though I am very sensitive to noise...

(presumably heat pump, gas condensing boiler system, controlled ventilation with heat recovery, air conditioning).

Wouldn't it be better to design the house in a way that most of these systems are not necessary?

What is your suggestion?

From my perspective, recently too much emphasis has been placed on insulation and too little on thermal mass. If you build the house using materials with good heat storage capacity, such as expanded clay aggregate (Liapor), and maybe construct a solid brick roof, the indoor temperature won’t drop immediately in winter when you ventilate thoroughly, and in summer you won’t need air conditioning. It should also be possible to size a heat pump (are you thinking more about deep ground drilling or horizontal collectors?) in a way that completely eliminates the need for a gas connection and a chimney. Personally, I would prefer a wall heating system over underfloor heating in that case, but of course, that is a matter of taste. And of course, the electricity for it should come from the roof.

So, in my opinion, even though I am a fan of technology, it shouldn’t be overdone in the house. Everything costs a lot of money, requires maintenance, can break down frequently, and you end up constantly chasing every trend, trying to solve the problems caused by the previous technology with even more technology. Not a good development...

Ideally, you only need photovoltaic panels on the roof and a heat pump with either deep drilling or horizontal collectors. Everything else should be handled by physics alone. In summer, the system can also operate in reverse mode.
