The Greenest Home in the World [Video]

I was noodling some recent journalist potshots about headlines for “the greenest …” when I landed on this video piece from the Nightly News. NBC’s Kiko Itasaki wonders if this home in Unst, one of the northern Shetland Islands of Scotland, is the greenest in the world.

Wood-Panel Passivhaus in British Columbia

Marken Projects is working on another Passive House in British Columbia.  This 3,500-square-foot home, made with a panelized prefab system like the Rainbow Duplex, will house two families and three generations under the same roof in Surrey, British Columbia.  The aim is an affordable structure that uses 90% less energy for heating and cooling than a standard home.  It’ll have triple-pane windows, an HRV, solar hot water, rainwater harvesting, no-VOC materials, and the ultra-efficient and airtight shell.   Construction will take about five months, and I’ll provide an update with more detail at that time.
