2. Building thermics
Here, we'll simply describe the useful elements of static (steady-state heat exchange) and simplified thermography of the building envelope during the heating season, in order to deduce how thermography fits into the process of observing and monitoring energy performance. Later, we'll take a closer look at the permanent risk inherent in the interpretation of thermal inertia, and thus the history of the building, its operation and the influences of its environment. To understand thermography, the thermal engineer will have to unravel the all-too-common simplistic approach.
2.1 Temperature and the three modes of heat transfer
"Thermal" comes from the Greek word thermè (heat), which gives us "thermometer" and "thermography"; the relationship with temperature is...
