> You’re one air con fuckup from asphyxiating on your own CO2 by the looks of it.
You might as well say the same thing about any sealed building, like virtually every skyscraper, or honestly most hotels I've stayed in (without exterior windows that you can open).
Buildings have air ducts for forced air flow. This isn't any different. Each capsule has one vent for fresh air, another that removes the air. It's the same way regular rooms work.
And oxygen and CO2 diffuse through air and ducts anyways, passively, even if blower fans fail. Plus there are additional gaps anyways for safety. You're not going to suffocate. They do actually think about these things in building codes. You're not allowed to build rooms that would suffocate someone if mechanical fans failed.
Ventilation for accommodation in the UK is extremely poorly regulated, or not at all, from what I can tell. I've been given rooms with a hermetically sealed window and no A/C unit.
I stayed at a brand new Hyatt the other day and the A/C had no "fan" only option (ie to avoid dry throats), and when off, provided no passive ventilation as far as I could tell. No opening window. And this was an aparthotel with a cooker etc. Absolutely ridiculous.
Premier Inn's budget 'Hub' brand chain have sealed windows and just wall-mounted A/C (not fed fresh air from a central duct). Should be illegal
I think legally they're allowed to use the 1 inch space under the door as ventilation...
You actually need a lot of ventilation in hotels because they often use very harsh chemicals especially in the linen
