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!

Our utility room does have a window, but it is never opened. However, we have a central controlled ventilation system for the living spaces, with the utility room connected as an exhaust area.

If you don’t have a central controlled ventilation system, you’ll need to install a decentralized ventilation unit—no matter the type. However, these usually pass through the exterior wall and would probably open into the garage, right?!

You can manage all of that with a controlled mechanical ventilation system. Personally, I would be more bothered by the pitch-dark room on the ground floor where I (well, not me directly 😀 ) sort laundry and so on.

Please show the floor plan that’s currently with the architect. 😉

Our utility room combined with the HVAC room is located in the basement, where there is only a small slot window in the shaft. However, since it is connected to the mechanical ventilation system (no surprise, as the unit is also located there), we don’t miss anything at all. Install a good flat panel light (LED panel with ≥ 4000 lumens, neutral white), and the lighting will be sufficient even without a window.

If you don’t have a mechanical ventilation system, you can still plan for a decentralized ventilation solution.

I don’t have any plans yet; they are currently being prepared.

A room adjacent to a garage can certainly have two external walls. The fact that it is next to a garage alone is not a reason to exclude a window.
