Embodied Energy Concrete, Steel and Glass.  The host for this show is Howard Wiig.  The guest is Linda Miki.

\nThe concrete, steel and glass in existing buildings is a treasure trove of energy.  The energy required to tear down a building, dispose of the rubble and then build with more concrete, steel and glass is enormous.  Repurposing buildings involves human, not material energy.  Repurposed buildings retain a sense of place and belonging in a city.
