3. Results
3.1. Thermal stress
Thermal stress is created when thermal expansion, or the change in size or volume of a given mass
with temperature is constrained. It is caused by difference in temperature or by differences in thermal
expansion [5]. The results of the four measured points show a higher thermal stress in the traditional
house during nighttime or early morning, while it is higher in the modern building during the
afternoon (Fig.4).

3.2. Temperature
The results show a surprising better behavior of a traditional house in terms of temperature in
comparison with a modern building even if the window had only a single glass. That is because of the
material used in the walls, ignimbrite stone, which can gain heat in the afternoon and retain it during
the evening much better than brick and concrete. Also, a double‐glazed window had a better
performance during the afternoon compared to that of a single glazed window, however the difference
is insignificant during early morning and nighttime (Fig.5).
