Hello dear forum community,
I wasn’t quite sure which subforum would be best for our question and hope I chose the right one :-)
As mentioned in another thread, my wife and I are currently planning a bungalow with two separate living units together with her parents. Besides the question about the heating system, we are also considering what type of ceiling to install over the garages. For the living areas, we plan to use concrete ceilings.
But what should we use for the garages? We have been advised by some people to go with a timber beam ceiling for cost reasons. However, since there will also be a utility room behind the garage, others say we should definitely use a concrete ceiling there as well. With a concrete ceiling, it is possible to install enough empty conduits during construction to make it easier to add electrical installations later on. That is difficult to do with a timber beam ceiling. Also, one must not forget the ring beam needed for a timber beam ceiling. In the end, the cost savings might not be that significant...
Now we are really at a loss for what to do...

WilderSueden30 Jun 2023 22:27These are two different things. Heat recovery helps to bring in fresh air that is not 30°C (86°F). But if it is warmer outside than inside, it cannot work miracles. However, it cannot eliminate solar gains or the heat generated by occupants and equipment inside the house.

Allthewayup1 Jul 2023 19:37We also covered the garage with precast concrete elements and used thermal break baskets to eliminate thermal bridges toward the house. Our general contractor wanted about 2,000 euros more for a pitched roof on the garage. The empty conduits ran from the house through the raw ceiling over to the garage to any desired location and were then filled with concrete. I would definitely do it this way again. For the garage door and lights, sockets were already installed in the precast elements at the factory. Everything went smoothly. A professional handled the sealing of the garage's flat roof, and from what we saw in between, it looked very good. If the roof ever leaks, repairs can be made quite easily without damaging the structure.
