ᐅ Utility room without windows – is a ventilation system sufficient?

Hello everyone,
Our floor plan is currently with the architect. We want to build an urban villa with an attached garage. The garage will be built from masonry. Since the garage is directly adjacent to the house wall, one room will inevitably have no window.
This will be the utility room with the heating system, washing machine, dryer, and other technical equipment.
However, I am a bit concerned about the heat and possible moisture these appliances might produce.
Would a 24-hour ventilation system (like those used in interior bathrooms) help, or would a small window—only opening towards the garage—be better?
Maybe someone else has a similar windowless utility room and can offer advice.
Thank you!

It's exactly as I suspected!

Accordingly, it is right in between. For example, the utility room is 4 m (13 feet) and the garage is 8 m (26 feet). 🙄
So the only option here is to wait for the plans.
Ok, so air conditioning is an additional system.
We planned to use a heat pump as the heating system. I have read that it can be combined with a controlled mechanical ventilation system.
Can anyone share some insights on this?
Also, I would be interested in a rough estimate of the initial costs.

Our heat pump Alpha Innotec WZSV 62K3M costs €12,094.67 net, including installation and commissioning. The controlled ventilation system Maico WS 320KB costs €6,897.44 net, also including installation. However, we carried out the ventilation ductwork from the air distributors ourselves (it’s not rocket science).
Additionally, there is a drilling of 110 meters (360 feet) at €5,280 net, since it is a ground-source heat pump. We expect that the Passive Cooling (PC) option, combined with wall and roof construction using materials that each provide high protection against summer heat, as well as appropriate shading with venetian blinds on all windows, will ensure tolerable indoor temperatures even during the peak of summer.
Of course, there is no single “best” heat pump or “correct” controlled ventilation system. A professional (preferably an energy consultant and a plumbing specialist) needs to be involved to carry out proper sizing. From what we have heard, heat pumps are often significantly oversized, which apparently negatively affects both efficiency and lifespan. Even if you plan to install an air conditioning system, I would not neglect the points of shading and building materials regarding protection from summer heat. Investments in the aforementioned aspects are one-time expenses, whereas air conditioning always consumes electricity (operational costs). Even with your own photovoltaic system (unused feed-in tariffs are basically money spent). 😉
