Infrared thermography Infrared thermography, a non-destructive technique, was applied to evaluate the southern façade of the Tamentfoust heritage building on 19 September, 2024, at 10:15 a.m., capturing surface temperature variations (24.9–33.2°C, mean 28.3– 29.9°C) (Fig. 20), to identify degradation patterns, including cracks, moisture, and heat anomalies, influenced by stone emissivity, humidity, and atmospheric conditions. Requiring 1.5–3 hours of solar exposure and an inspection distance of
