Abstract [en]

The earth is our sustainer, the chain of ecologic survival. Renew ability is the key to our human continuum and our prime resource for architecture. Earth sheltering earth handling and earth escaping are more clearly pronounced in the vocabulary of architectural planning and design  . Many of us had percept the positive effect in underground tunnels by traveling through the metro. The vital and efficient sustainable energy which can be used by us is underground thermal inertia; we can become aware of that, the earth can serve in many climates as a heating or cooling source. Its high thermal capacity keeps the soil temperature, below a certain depth, considerably lower than the ambient air temperature during summer and higher than the ambient air temperature during winter. Seasonal variation of the earth temperature decreases with increase of depth, moisture content of soil and soil conductivity. It is estimated that a small number of meters below the earth surface, the earth temperature remains constant during the year. In regions with temperate climate such as Denmark, the temperature of the soil at depth of 2-3 meters can be low enough during summer or high enough during winter, to serve as a cooling or heating source. Using of the underground constant temperature can be useful for architects and designer because the temperature is between 8ºC-13ºC, and2- 3 m above the earth, can help us to find a competent solution which help us to controlled thermal comfort in houses.
