Cook: This is what sustainable building looks like

Build two rooms.

One, the old way: standard building techniques, modeled on outdated codes from a decade ago, before Lebron had even left Cleveland.

Sure, the room may keep out the rain. But it leaks air. The insulation is poor. The framing is short-sighted.

So, build a new, second room. Based on the most forward-thinking and advanced building and insulating techniques, this room is different. Warm in the winter, cool in the summer, the room also uses less fossil fuel energy. And it’s more affordable.

Then, take these two freestanding rooms – old room, new room – and put them on display in a public place.
