Cooling accounts for a much larger percentage of global energy than heating. Stainless steel plays a key role in a new generation of adsorption chillers, the heart of environmentally friendly cooling equipment.
Sunscreens greatly reduce the need for air conditioning in buildings. The Federal Building in San Francisco was built with computer-controlled stainless steel sunscreens which, together with natural ventilation, reduce the energy needed to cool the building by two-thirds. The stainless steel is highly corrosion resistant and is specified for a design life of 100 years.
