In January, my house construction will begin.
Something I am wondering about is how they install all the spiral ducts for ventilation to all the rooms in the ceiling?
The house is a single-story. The thickness of the ceiling will be around 500-600mm. (gable roof)
Do they hole-saw in the beams for the spiral ducts? If they do, doesn't that weaken the construction?
Now, I don't know the diameter of the ducts, but let's say if it's, for example, 160mm, that's quite large holes.
Does anyone know?
You can remove a MAX of 20-30mm on tokstolar without affecting the construction of the roof trusses, to run any water pipes. Preferably, you shouldn't do it.
If the construction from the beginning is such that there is no room for ducts elsewhere, the trusses must be sized for openings of this size. Likewise, duct routing through trusses, which are often spaced at cc-1200, falls at the very bottom in terms of tasks. It is most common that the truss itself is not 500mm high in solid wood unless there are extreme spans, but instead of a truss construction or a scissors truss, and then ducts are routed in the spaces between the top chord and bottom chord.
I haven't received a ventilation drawing yet, but I've received a construction drawing for the roof trusses and they had to be quite "sturdy" apparently since the house is 14.4m wide. In the middle, there will be a glulam beam which I believe was 115mm * 500mm, around 16 meters long. Then some form of glulam beams as the roof trusses, since they will be about 8m long from the outer wall and then resting on the center beam that's about 4m high. 1200cc, if I remember correctly.
Just one of my 2 million thoughts running through my head daily about the house construction
I'll take a closer look at how they have planned the ventilation, etc.
Ps. Great feeling today when they parked a big excavator on the plot and my self-designed house will soon begin
There is a VP (heat pump) in the laundry room. Have you chosen a heating solution? If it is an exhaust air heat pump like Nibe 750, it gives some clues about the ventilation.
Was initially going to have ground source heating, but it will be geothermal heating instead. The idea is to have a pump with exhaust air. What do you mean by clues for vent?
If you are only going to have an exhaust air heat exchanger connected to the geothermal heat pump, it is primarily exhaust air ducts that should be installed. So if the ridge goes from lower to upper edge in the picture, you should run a duct along the roof trusses from the WC on the left, a duct from the bathroom in the middle of the house, and then some local routing in the utility room with the laundry room.
You should run exhaust ducts from the WC and bathroom into the laundry room. I assume the bathroom extends all the way up to the ridge in the middle? It seems suitable to run the ducts in the insulation between two rafters, roughly where the line that cuts through the three rooms on the plan is.
Then you need a duct to the kitchen. It should be able to run in a similar way, just a bit further down in the picture and into the bedroom at the bottom right.
