PCI Residence

Designed by Pb Elemental Architecture. The PCI Residence glows, literally — the home's exterior is made up of 100-percent recyclable polycarbonate walls, which illuminate the home from dawn to dusk, as well as a custom LED lighting system. Chris Pardo, cofounder of Pb Elemental Architecture, says the design "was based on the concept of interacting with and utilizing nature." Among other green building techniques, the home incorporates rooftop solar panels, in-floor radiant heat, a rainwater-harvesting system and low-impact materials such as raw concrete and raw steel.
