Farm house located in Keldur, Iceland. Earth sheltering is the architectural practice of using earth against building walls for external thermal mass, to reduce heat loss, and to easily maintain a steady indoor air temperature. Earth sheltering is popular in modern times among advocates of passive solar and sustainable architecture, but has been around for nearly as long as humans have been constructing their own shelter.
Green facades are a contemporary take on something we have been doing for centuries: growing plants on walls. Climbing plants can shield your home, studio, or garage from direct sunlight, and are an effective way to reduce the internal temperature of a house in summer.
