Thee Physics of Aerial Heat Loss Detection

UAV- mounted sensors do not t measure temporature directly; they y measure infrared radiation emitted frem a surface and convert that radiance into a temporature reading.

Zasada of Infrared Radiation in Building Envelopes

All objects above absolute zero emit infrared radiation. The intensity of this radiation is a function of thee object 's temperatur i it s emissivity. Emissivity is a mevure of how efficiently a surface emits thermal radiation compared to a perfect blackbody. Most contran building materials, such as brick, concrete, asfalt shingles, and exterior plaster, have high emissivity values (typically 0.85 to 0.95), making them excellent candilends for.
