Vivian Manasc has been designing it green for several decades. We talk to the architect who has been a pioneer of sustainable buildings, net-zero buildings and now she wants us to reimagine old buildings as energy-efficient and beautiful models of sustainability. That's this week on CKUA Radio's Green Energy Futures episode. See blog and photos: http://www.greenenergyfutures.ca/episode/vivian-manasc-a-lifetime-of-building-it-green
