Energy Efficiency

One of the more interesting ideas in cooling technology has a surprisingly small source of inspiration: the Saharan silver ant.

Hong Kong company i2Cool has developed passive cooling materials inspired by the insect’s ability to survive extreme desert heat. Its coatings aim to keep building surfaces cooler without electricity powering the cooling process.

The science behind it is real. Research published in 2015 found that the ant’s distinctive silver hairs help reflect sunlight and release body heat through infrared radiation. Essentially, nature gave these ants a way to manage heat long before anyone fitted a split system.

i2Cool applies similar principles to building materials. Its coatings combine high solar reflectivity with the ability to release heat as infrared radiation. The company reports solar reflectivity of up to 95% for its cooling coating—meaning much of the incoming sunlight is reflected rather than absorbed. That figure describes reflectivity, not a 95% reduction…

Discover how differential pressure control and VSD tuning can cut chilled water pump power use by up to 30% in Australian HVAC plants.

Chilled water systems are among the biggest consumers of electricity in large facilities.

By fine-tuning differential pressure (DP) setpoints and verifying sensor calibration, operators can ensure pumps only work as hard as needed.

Adding VSD logic control through your BMS (e.g., 180 kPa setpoint with floating adjustments) can dramatically lower consumption.

Regular testing of DP sensors, valve operation, and auto staging logic prevents energy spikes and stabilises flow rates across the building.
