For a room without a window
When a room has no windows, you can open the room door and place a fan or similar device to enable the flow of air outside the room. The air from other rooms is also effectively discharged outside the house by operating a ventilation fan for a bath, lavatory, or toilet.
Yes, you can have a utility room without direct external ventilation, but it's essential to manage airflow and moisture effectively to prevent problems such as damp, mould growth, and poor air quality.
Extract ventilation can be intermittent or continuous. Your extractor fan should be installed as high as is practicable in the room — and a maximum of 400mm below the ceiling. Minimum intermitted operation extract systems (in litres per second) are 30l/s in a utility room.
An exhaust fan is a good idea in a bathroom, particularly one with no window. It will take the highly humid air out of the room, which helps prevent mold and mildew, and fogged mirrors.
Air is essential to proper combustion and that is why proper utility room ventilation is essential to make a furnace, boiler, or water heater work properly and safely.
CO2 levels that are higher than 1150 ppm will typically occur in bedrooms that are not fitted with a ventilation system and where windows and doors are closed. Above 2600 ppm: Insufficient ventilation—both sleep quality and next-day performance are adversely affected.
Cooler Room
Your washing and drying machines can give off a lot of heat when they're running, increasing the temperature of your laundry room. To keep things cool, you'll want to install a laundry room ceiling fan.
Can you do that? No, you can't. According to Section R310 of the International Building Code (and most other building codes), every bedroom needs an operable window that can act as a second means of egress during an emergency—so landlords can't count windowless rooms as bedrooms.
So, once you've installed a sink, appliances, worktops, and plenty of storage, all you need is a small, cupboard-sized space that comfortably fits a toilet and cistern. If you're particularly short on floor space, remember to make the door open outward into the utility space rather than inwards.
Laundry room ventilation is important as it can be a major source of contaminants in your house. A poorly ventilated laundry room will have moisture buildup. During the hotter summer months this is a recipe for mold growth, bacteria, and dust mites.
Passive ventilation methods are driven by natural principles. The two main ones are wind-driven, which uses the wind to move air through a building, and buoyancy-driven, which is based on the fact that hot air rises, and is replaced by cold air. Joanna Hunter.
Cross ventilation (single spaces): Being unsophisticated and efficacious, this type of ventilation is a horizontal process that is driven by pressure differences between the windward and leeward sides of the occupied indoor environment.
Health Implications of Poor Ventilation
Prolonged exposure to these airborne contaminants can trigger or exacerbate respiratory problems, such as asthma, allergies, bronchitis, and chronic obstructive pulmonary disease (COPD).

Ventilation. Ideally, a utility room will have a window to assist ventilation and bring natural light in, but this may not be possible, for example in a garage. Heat and moisture from washing and drying clothes needs to be tackled to prevent dampness and mould.
Typically, habitable rooms provide the living accommodation of the dwelling. They include living room, dining room, study, home office, conservatory and bedrooms. They exclude the bathroom, WC, utility room, storeroom, circulation space and kitchen (unless it provides space for dining).
While some home designs include another form of ventilation for the room, “closet-style” laundry rooms should allow heat to escape through a vented door. If you don't go with a vented door, keep the laundry room door wide open while you run the machines.
In windowless bathrooms, use ventilation systems and dehumidifiers. Plants play a significant role in the bathroom, beyond their decorative function. Green plants are a real plus for a healthy indoor atmosphere as they act like a sponge, soaking up excess moisture.
Ductless bathroom fans pull air out of the bathroom and run it through a charcoal filter. The charcoal filter removes moisture and odor from the air which provides a number of benefits for the bathroom.
Using a Floor Duct Vent
In bathrooms without outside access, duct vents can be used to ventilate bathrooms if ceiling venting is not possible. A floor duct vent is a special machine that uses floor grates to remove moisture and bad air from your bathroom.
