Well that's the end of our #PassivhausChallenge there was almost zero solar gain today so putting the heated towel rails back on in bathrooms. Could probably endure going longer without but that's not the point, we'll use very little energy to stay comfy 🙂

A few notes after the #PassivhausChallenge
- we didn't change our behaviour for this experiment, we simply turned the heating off
- house remained comfortable as long as there was some ☀️ to top up the heat
- it's unlikely we'd last nearly 10 days in much colder/ overcast weather

#PassivhausChallenge notes (cont)
- #FuelPoverty is real and many people cannot afford to heat their homes, they simply have no choice
- we did this from a very privileged position
- I wish everyone could live in a home which stays comfortable with very little cost
