Passive solar design is something that some people close to me are looking at for a new home.

Homes constructed as passive solar design use the natural movement of heat and air to maintain comfortable temperatures, operating with little or no mechanical assistance.

Basically, passive solar uses the sun to heat a home, using things like “thermal mass” (large amounts of brick, or water, or some such) to catch heat which can then radiate, convect or conduct out) and then heat the surrounding interior.

The article here does a great job of outline this, and other essential components of passive solar design.

There’s a lot more to be said about this, but it’s definitely a greener, more off-grid solution for the future: a great thing if there’s a solar storm!
