Startup Spotlight: Node offers airy energy efficient homes that aim for easy, pre-fab installation

It’s pretty ambitious to launch a business that’s trying to address one of the big challenges confronting the world. A Seattle startup called Node hopes to help tackle two of them — climate change and affordable housing — through its innovative home designs.

The 2-year-old company is developing what it’s calling “slide, click and lock” technology that will allow just three or four people to assemble energy-efficient homes out of components made from planet-friendly materials.

“What drives us is hitting the scale that will change the [housing] industry for sustainability and creating access for people trying to get housing,” said Node co-founder Bec Chapin. “We started Node because buildings account for 47 percent of carbon emissions, yet all of the technology exists for buildings to be carbon negative.”
