Study and Application of Earthen Air Tunnel in Abhalmaya Office Building, Sangli, Maharashtra

The phenomenon of mean earth temperature is the property of earth that at a depth of about 1.5 to 2 m, the temperature of ground remnants nearly constant all through the year. This constant temperature is called earths undisturbed temperature which remains higher than surface temperature of earth in winter season and lower than surface temperature in summer. For effective utilization of heat capacity of earth, the earthen air tunnel heat has been introduced to building. The earthen air tunnel are considered as one of the most passive system due to its ability to provide both the effects; heating in cold months and cooling during warm months. They use the earths near constant subterranean temperature to warm or cool air for residential, agricultural or industrial used. This paper reviews the learning outcome from the case study Studio 8-8-8 Abhalmaya an Architect Office in Sangli Maharashtra which represent the internal temperature difference of about 10% as compare to external temperature which are very much beneficial in a place like Sangli where average annual temperature is about 25.4 °C and average summer temperature is about 30 °C.
