Mirrored ductwork extends daylight

Mirror Duct System – post on Transmaterial about a duct system that’s lined with reflective aluminum mirrors which can “extend light as much as sixty feet inside a structure.”

Developed by Tokyo-based Material House, Mirror Duct System is a completely passive technology that contributes to CO2 reduction by decreasing electric power usage for lighting as well as the additional cooling often required.

See a diagram of an installation at Toyota Motors Main Building here and more general information about the use of mirror ducts in Singapore here.
