SESEN-ATEN TEMPLEPassive Thermoregulation with Unreinforced Masonry
Aurimas Bukauskas | Phillip Hu
The Sesen-Aten Temple was inspired by Guastavino’s thin unreinforced masonry vaults, and Eladio Dieste’s doubly-curved concrete shell structures. Our design explores the ability of unreinforced masonry forms to perform passive thermoregulation in a desert climate.
A central oculus, 20 feet in diameter, allows direct sunlight and precipitation into the building. Some light enters through the solar chimney.

This �ow of hot air draws air up and out of the building, �ushing it constantly. Air passes underground to cool before it enters the building.

Oculus Sizing
Dome Sizing
The walls of the dome are 24” thick near the base, providing su�cient thermal mass and thermal resistance to reduce temperature �uctuations between day and night.
The masonry �ns act as a solar chimney by absorbing solar radiation and heating the air around them, creating a convective updraft.
