Phoenix has been a concrete jungle for as long as I can remember. It’s consistently hotter than Tucson despite being 100 miles north and only 1000 feet lower in elevation.
I sometimes wonder how much the city could do to help itself by drastically changing its urban planning process.
Add trees (mesquite does well in Tucson) where possible. Cover any blacktop with solar. Use highly reflective/white paints or rock for exposed surfaces. Implement reasonable public transit… except it’s notoriously hard to design for such sprawl.
Another fun idea would be to dig deep and create large subsurface buildings to reduce AC usage.
There are so many buildings in the southwest that are built to withstand the temperature differences 100 years ago. Seems like a new standard needs to be adopted.
- csb6 2y agoUnfortunately much of Phoenix is covered with a hard layer of soil known as caliche that is expensive to dig through, meaning that most houses don’t even have basements. But if it saves a lot of money on cooling it might be worth it.

- mlinksva 2y agoWonder if adding ~8 feet (a typical basement dig depth) of fill could be less expensive? After basement floor is built? Perhaps a development could be planned around this. Or, the lower floor of entire neighborhoods could be turned into basements, with stories added as desired. Areas of cities have been raised in similar manner, for different reasons, eg after a flood in Sacramento, after a fire in Seattle.
- imoverclocked 2y agoBurying a basement layer above existing grade is interesting. I hadn’t considered the possibility of backfill to create more thermal mass but it makes sense to me. It would require importing a fair amount of material though. I would need to understand where that material comes from and the overall impact it would have to do it at scale.
- yowzadave 2y ago> Implement reasonable public transit I agree this is the right idea, but you may have seen other commenters in this thread talking about how Phoenix is fine because you can just go from your AC car to your AC garage without having to walk in the heat. Imagine how people like this will react when you tell them they'll have to walk to a train stop!
