Upstairs temperatures (Hobos 13, 14, and 15) are shown in combination with north outdoor temperatures (blue; Hobo 23) before and after brick installation. Unexpectedly, thermal variations even at this distance from the bricks showed quite similar results to those recorded downstairs: temperature lows were delayed by several hours relative to outside temperatures, and peaks and valleys smoothed noticeably, especially on March 14 and 15.
