Igloos:

On the outside, temperatures may be as low as −45 °C (−49 °F), but on the inside the temperature may range from −7 °C (19 °F) to 16 °C (61 °F) when warmed by body heat alone.

I can't readily find a source with details, but traditional desert cities were located on high ground and the streets oriented to catch the winds such that daytime street temperatures were pleasant.

We used to design buildings and cityscapes to work with the local climate. Now, we slap up cardboard boxes, inject insulation and add HVAC systems, counting on technology to keep things comfortable in place of good design. In reality, well designed buildings are more comfortable and probably less likely to suffer from sick building syndrome.
