Encycle - Termite Swarm Logic HVAC Optimisation — Encycle

Biological model: Termite swarm collective behaviour

Company: Encycle

Termite swarm coordination logic inspires decentralised building HVAC systems that optimise energy without central controls.

The challenge

Building HVAC systems waste 30-40% of energy through centralised thermostat control that cannot respond to local microclimate variations. Smart buildings require expensive distributed sensors and sophisticated algorithms. Simpler, more resilient control approaches are needed.

Nature's strategy

Termite colonies maintain mound climate through collective decision-making based on local environmental cues and pheromonal communication, with no centralised control.

What was emulated

Distributed decision-making; local environmental sensing; chemical communication analogues; collective optimisation; resilience to individual failures; adaptive behaviour.

The innovation

Distributed vent network using termite-inspired local rules and pheromonal-analogue signalling, optimising HVAC without centralised control or complex algorithms.

Full case study

Termite colonies maintain precise temperature and humidity within their mounds despite external temperature swings of 40°C+, using only passive airflow and pheromonal signals—no central control, no energy input. Individual termites follow simple local rules: open vents when CO2 rises, close them when temperature exceeds threshold. Collectively, these local decisions create global optimisation, maintaining homeostasis across the entire structure. There is no termite CEO directing airflow; the colony operates as a distributed intelligence system. Encycle recognised that building HVAC systems mimic this structure-scale problem perfectly: maintain indoor climate efficiently without centralised control that requires expensive sensors and computational infrastructure. The company developed a network of 'smart vents' deployed throughout a building, each following termite-like rules: measure local temperature, humidity, and CO2; decide locally whether to open or close; signal neighbours through wireless mesh. No central thermostat, no complex algorithms—just termite-inspired pheromonal-analogue signalling. Field trials in office buildings show Encycle systems reducing HVAC energy consumption by 15-25% versus conventional thermostat-based systems, whilst maintaining tighter temperature control and superior air quality. Critically, the system scales: adding rooms requires no recalibration, and failures cascade gracefully—a failed vent triggers neighbouring vents to compensate automatically.
