How can you measure door-opening effects per route?

Do not assume fixed energy per opening; link duration, conditions, and temperature response to stop records.

Short answer

Do not assign one fixed energy cost to every container-door opening. Match opening count and duration on a route with ambient and internal temperature logs, load state, and closure time. Compare similar routes and observe changes in the temperature trace; a logger alone does not measure the amount of heat entering.

An opening's effect depends on aperture, duration, inside and outside conditions, and load layout. Therefore record the time, open-to-close duration, section opened, and load state at each stop.

Place a temperature logger at a point suitable under the product procedure and monitor ambient conditions too. Align stop records with changes in the trace by time; the trace alone does not quantify heat exchange.

Test different workflows on the same route with a comparable load, such as completing preparation in advance or grouping openings. Compare duration, temperature profile, and exceptions; leave product-band decisions to the authorised quality owner.
