building method and buildings

Abstract

A method and designs of underground buildings for any purpose that do not introduce any element above ground level, thus allow agricultural use of the land by any agricultural machine or technology or using the land for recreational park.

1 . A method that allows using land for agricultural or recreational purposes and build building underground this land for human use comprises of:
 a. an underground building which is completely under ground level;   b. a layer of soil on top of said building, having top surface in about similar level of nearby soil so that the soil enables agricultural purposes or green park for recreational activities.   
     
     
         2 . A method according to  claim 1  where underground building has access tunnel which its exit is far from the underground building perimeter. 
     
     
         3 . A method according to  claim 1  where underground building has ventilation system that intake fresh air through pipe which its intake fresh air opening is not interfering with potential agricultural activity. 
     
     
         4 . A method according to  claim 1  where underground building has ventilation system that intake fresh air through pipe which its intake fresh air opening is far from the underground building perimeter. 
     
     
         5 . A method according to  claim 1  where underground building has ventilation system that comprises retractable intake air pipe. 
     
     
         6 . A method according to  claim 1  where underground building has ventilation system that comprises powered fan that cause fresh air entering and leaving the ventilation system. 
     
     
         7 . A method according to  claim 1  where underground building has ventilation system that comprises devices to increase or decrease the airflow within the ventilation system. 
     
     
         8 . A method according to  claim 1  where underground building has ventilation system that comprises devices that control the air-pressure within the underground building. 
     
     
         9 . A method according to  claim 1  where underground building has ventilation system that comprises high-pressure air tanks to provide fresh air to underground building occupants. 
     
     
         10 . A method according to  claim 1  where underground building has ventilation system that exhaust air through car access tunnel thus removing cars exhaust gases entering the underground building. 
     
     
         11 . A method according to  claim 1  where underground building has electric generator that provides electricity in case of public electricity failure. 
     
     
         12 . A method according to  claim 1  where underground building has emergency lift car and shaft that while not in use, do not interfere with potential agricultural activity of the land above the underground building. 
     
     
         13 . An underground building according to  claim 1  having a convex structure dome to carry soil load. 
     
     
         14 . An underground building according to  claim 1  having a basin that collects water seeping into the building. 
     
     
         15 . An underground building according to  claim 1  having a drainage system that removes water from water basin. 
     
     
         16 . An underground building according to  claim 1  having corridors connecting it to another underground building. 
     
     
         17 . An underground building according to  claim 1  having parking places for cars. 
     
     
         18 . An underground building according to  claim 1  having electric vehicles for transportation within the building.
