Twenty Eight Point Eight Degrees
This morning I woke at 4 to have a shower, have breakfast, and then drive to Morges for a 6am run. As a result I had no opportunity to open windows, aerate or anything else. I kept every room closed so each room is a compartment.
The result, is that the temperature in my flat has been completely flat, varrying by .01 of a degree throughout the day, rather than huge fluctuations.
