Part III: Daily temperature cycles, east wing
This five-day period was a testing time for the unheated solar-passive house. Days were at their shortest, some nights were frosty, and overcast persisted for two days. It fell within a cold, wet, and cloudy winter.
This post is about the single-storied east wing of the house. It is the main part of the house, with most of the clearstory windows.

Observations
In this wing, seen on the left in the photo, five thermometer stations define a profile in height. They are:
Subsoil in the heat bank beneath the house;
On the floor slab;
On the room wall;
In the clearstory space;
OUTDOORS, in a Gill Screen, 1.5 metres above the ground and eight metres from the house.
During the five days I made 84 observations at each station at intervals as shown. They define the daily temperature cycles. I observed the amount of cloud in Octas (eighths of the sky) at the same intervals.
This table lists for each thermometer station the five-day values of the average, maximum, and minimum temperatures, and the temperature range.
