When considering the thermal insulation of bee hives, we also have to consider the honeycomb construction with its air layers in between. These layers themselves act as thermal insulation. The more honeycombs between the bee cluster and the side wall, the higher the insulation. I.e. with regard to the side thermal insulation, the broad constructions of the modern hives are quite helpful.
In December 2017 I took measurements on a beehive with a Diffusion-lid for 2 weeks to get an overview of the average temperature below the lid. For this purpose, 7 temperature sensors were installed as shown. The values given are the average temperature difference between the sensor and the outdoor temperature. The average temperature difference … Read more
