🧪 Experimental Hive Microclimate Lab

About this simulation

Beyond the standard Langstroth box, experimental beekeepers trial tapered Warré hives with insulating quilt-boxes, long horizontal top-bar troughs, and even geodesic-dome "sundome" hives — each changing surface area, air volume and how the colony's own metabolic heat is retained or lost. This lab is a simplified cutaway model of that trade-off: bees generate a steady amount of heat, and the hive's shape, wall material, wall thickness and ventilation together decide how much of it stays inside.

How it works

• Internal temperature is estimated from a simple thermal-balance model: colony heat output divided by total heat conductance (wall conductance from material and thickness, plus ventilation conductance).
• Better insulation (thicker walls, higher-R materials like polystyrene) and less ventilation raise the internal temperature above the outside air.
• Thin walls, low-R materials (mesh, cob) or wide-open vents let internal temperature drift toward the outside temperature.
• The bee cluster visibly contracts into a tight winter ball when the interior runs cold, and spreads out — with bees fanning and "bearding" near the entrance — when it runs hot.
• Rising particles show the convective airflow current through the hive, faster and more numerous with a larger vent opening and a bigger inside/outside temperature gap.

Controls

• Hive design — swap between four experimental and conventional hive body shapes.
• Wall material — cedar wood, polystyrene foam, clay/cob render or open mesh screen.
• Wall thickness — how thick the insulating shell is, in centimetres.
• Ventilation opening — how much of the entrance/mesh floor is left open.
• Outside temperature — the ambient air temperature the hive sits in.
• ↺ Reset trial — restarts the airflow particles. Drag to rotate, scroll to zoom.

Did you know?

This is a deliberately simplified teaching model, not a validated thermal simulation — real hive microclimate studies use dataloggers placed at multiple comb heights over full seasons. The article this accompanies stresses running any unconventional hive as a small, monitored, side-by-side trial before converting a whole apiary.
