Read the envelope from the air.
The whole envelope inspected without a scaffold, with the wet and the loose already marked on the elevation: roof moisture, standing water and hot switchgear after sundown, sealant, spalling and glazing read at 2 cm on the face. No swing stage, no rope crew, no shutdown.
What it does
The pass reads what the eye cannot: wet insulation still giving back the day's heat after sundown, a roof drain that never drains, a breaker running 14 °C above its neighbours. Every reading carries a temperature rather than a colour — pick a point weeks later and the number is still there.
The facade pass reads the elevation instead of the plan: the whole face at 2 cm, every finding tied to a grid line and a level. Defects mark on the elevation drawing, not on a photograph nobody can locate again in March.
In practice
- 01
Fly the right window
Thermal goes up after sundown, when wet build-up is still releasing the day's heat and the roof around it is not. The facade pass flies in flat light. Both are saved plans, so the next inspection repeats them line for line.
- 02
See the hot spot and the thing that is hot
The temperature and the picture of what is warm arrive together, at 2 cm on the face, so nobody argues about which bay the reading belongs to.
- 03
Mark it on the elevation
Findings pin to a grid line and level on the facade, or to a roof area on the plan, and go to the record as observations with an owner, a due date and the frame that proves them.
