Open ALL doors & windows
First thing in the morning, throw the whole house open and flush it with the cool overnight air while it's still free.
By 10am (or the second I leave) → close everything
Shut every door and window before the day heats up. Lock the cold in, lock the heat out.
Close all shades & blinds
Block every beam of direct sunlight. No free solar oven today, thanks.
Downstairs holds ≤ 26°C all day
The sealed, shaded ground floor stays a cool 26°C while the outside world cooks.
Stay sealed & shaded
Outside is still equal or hotter. Keep the house buttoned up tight.
↻ keep checking the temp gap…Half a degree colder out there → GO
The moment outside drops even 0.5°C below inside, it's harvest time. Fling the windows open.
🌀 The Negative-Pressure Power Move
Park the big fan in a window pointing OUTWARD. It blasts hot inside air out, dropping the house's air pressure. The whole place becomes a vacuum that sucks cool outside air in through every other open window — a free, whole-house cross-breeze on demand.
Meanwhile, the dumbass neighbors…
…have every window flung wide open at high noon, just letting that 39°C heat pour straight in. Free entry for the furnace. Bless their little thermostats.
Backup unit · upstairs bedroom
That cheap-but-helps A/C I bought ~3 years ago. Not glamorous, but it earns its keep upstairs.
🔥🍔 Step 10 · Exile the cooking heat too
Do not fire up the stove and dump heat straight into the sealed fortress. Grill the burgers OUTSIDE so every bit of cooking heat stays the fuck out of the kitchen. The house never even finds out dinner happened.
Also… you get to have burgers
Cold house and burgers. Cooling strategy that feeds you. There is no downside here. None.
Be smug as fuck.
House at 26°C. Burger in hand. Energy bill barely moved. Neighbors melting. You won.
