Description - Figure 3 - Comparison between temperatures in a Montréal duplex and in the ambient environment, July 7-9, 2010

The graph is a comparison between temperatures in a Montréal duplex and in the ambient environment. Different colour lines indicate indoor temperature (green solid line) and outdoor temperature (orange dotted line) over a two day period, July 7-9, 2010. During the daytime, for both days, ambient indoor temperature reached levels above 34°C/93°F. At night, ambient indoor temperature stayed above 31°C/88°F, thus demonstrating a lack of indoor nighttime cooling. Alternatively, outdoor ambient temperatures exhibited a greater fluctuation over the two day period; temperatures dropped to 24°C/75°F at night and rose to a maximum of 32°C/90°F during the day.
