Hands up, who else is stuck in an uninsulated and poorly ventilated housing situation?
I barely survived when we had 40c, it reached 50c in my flat and the humidity was truly horrific, it was like living in soup.
I have a dehumidifier now and lots more fans, but I'm still struggling in this heat we're currently having as this building is entierly uninsulated and the bedsits it's divided up into are very poorly ventilated. The heat rising from the floors and radiating through the internal walls is like being in an oven.
You're welcome to crash in my 150 year old 2-foot thick stone wall house with fuck all insulation that's unbearably freezing year round.
It's one way or the other in this country. Sweaty new-builds with no air con, or ancient glorified caves that wouldn't heat up if they were on fire.
We're slowly getting there. MVHC imo is going to be the next big one that goes in the regulations.
The concept is, you seal the house up so that airflow doesn't happen unless you want it to.
Then set up heat exchangers with ducting between the rooms.
So fresh air can be brought in, cooled/heated by the stale air going out.
And it also lends itself well to aircon systems.
There is also Part O of the building regs, which uses calculated shade on south-facing windows to minimise solar gain in the hottest months.
