Passive houses work both ways. 33Deg CÂ* 22Deg C

How do you get such a large temperature difference?

Insulation, insulation, insulation and/or bury your house.

Not insulation. Thermal Mass.

te huge lumps pf masonry in my chinmneys and the huge cast concrete
ground floor, all end up at the average tempearture beytween day and
might. Around 26C

By day, draw the curtains and shut the windows. at night reverse that./

Passive houses have both.
Thermal mass and lots of insulation round the outside.
I also have 100mm insulated shutters and doors.
