The document describes several types of traditional dwellings from around the world that provide natural temperature regulation:
1) The Uros people live on reed islands in Lake Titicaca in Peru and make their houses, boats, and islands entirely from reeds, which help insulate them from the cold.
2) Korean Ondol houses have underground heating systems that circulate warm air to keep occupants comfortable without drafts during cold winter nights.
3) Cueba houses dug into valleys in Andalusia, Spain maintain a comfortable 40 degree temperature underground even in winter.

above sea level. About 2,000 Uros people live
on 50 artificial reed islands. The Uros people
make a living by fishing and tourism. The
houses, boats and islands are all made out of
reeds.
