Energy Transitions

Steel Zero is an architecturally attractive building façade system that harnesses the sun’s energy for use within a building’s heating, ventilation and air conditioning system.

Steel Zero heats air by drawing relatively cold outside air through a spectrally selective solar heated steel sheet. This solar heated air is then ducted into the building, reducing the building’s space heating demand.

Steel Zero is the world’s first solar air heating with a long-life spectrally selective (low emissivity) coating. The high air temperatures that can be generated by Steel Zero also has uses in agriculture and industrial drying.

To create Steel Zero, Energy Transitions have used the latest advancements in sustainable air-flow engineering. These engineering advances enables each new Steel Zero collector to consistently delivery high efficiency solar air heating.
