What if upgrading your home to be climate-friendly was as simple as scanning it with your phone?

In this week’s episode of the Climate Confident Podcast, I talk with Grant Gunnison, founder and CEO of Zero Homes - a former NASA and MIT engineer who’s now tackling one of climate tech’s toughest challenges: decarbonising existing homes. His company uses smartphone scans and digital twins to design fully-scoped, permit-ready electrification plans - no site visit, no clipboard, no chaos.

You’ll hear how Grant’s team is cutting out the “truck rolls” that make home upgrades expensive and slow, saving homeowners money while helping contractors stay profitable. We dig into why electrifying 60 million U.S. homes is both an engineering nightmare and a golden opportunity, and how technology, not policy alone, can finally make it scale.

We also unpack the human side: what really motivates homeowners to switch to heat pumps, why induction cooking is a secret health win, and how removing the awkwardness of having strangers poke around your home can actually accelerate climate action.

🎙️ Listen now to hear how Zero Homes is reshaping the future of home electrification - making sustainable living smarter, faster, and far more comfortable.
