Earth sheltered building technology

Abstract

The earth sheltered building consists of a thin elliptoidal shell which is attached to a generally curvilinear top viewed foundation. The elliptoidal shell meets the foundation at a generally horizontal latitudinal plane which is spacially below and parallel to the equatorial plane of the elliptoid. The building has ingress and egress means defined generally by the intersection of a pair of latitudinal lines and a pair of longitudinal lines of the elliptoid. Ingress and egress means can also be obtained by the omission of any meridian surface section of the elliptoid or any section defined by a plane spacially parallel to a meridian plane. The building can also be elongated by placing a vaulted section of elliptic vertical cross section congruous with two hemi-elliptoidal shells. The building can be constructed by the use of predetermined inner and outer form panels which assemble into inner and outer form networks. These networks are spacially parallel and result in a form system having concavo-convex cavities into which building material is placed. The resultant thin shell elliptoidal structure from the use and method of use of the inner and outer form networks is optimal in distributing the forces that result when the structure is sheltered with earth components such as dirt, gravel, berming, etc. while, simultaneously, providing an interior space which can be optimally utilized for habitation.
