To solve climate change, we need to get rid of every area of emission.
People think a lot about electricity and transportation, but a lot less about buildings.
The challenge is not just how we build new buildings, but what we do with all the buildings we have now.
So one great innovation in this space is about windows.
Today's windows let the heat come in or the heat go out.
You have to run your heater during the winter a lot more.
It costs you money.
It's bad for climate change.
Well, so what Luxwall did, as they said, can't we make a window that has a couple layers of vacuum in there that block the heat and so your house stays warm with far far less energy.
Another company, Aeroseal, has a solution for the problem of buildings leaking energy.
