Abstract
A thermally-regulated building structure including a foundation for supporting the thermally-regulated building structure on the surface of the Earth, and one or more coaxial-flow heat exchanging structures installed in the Earth, for facilitating the transfer of heat energy between (i) an heat energy exchanging system maintained within the thermally-regulated building structure and (ii) the Earth environment. Each coaxial-flow heat exchanging structure includes an inner tube section being substantially straight and having an outer wall surface extending between the proximal and distal ends, and a thermally conductive outer tube section, disposed coaxially around the inner tube section, and having an inner wall surface extending between the proximal and distal ends. An outer flow channel is provided between the outer wall surface of the inner tube section and the inner wall surface of the outer tube section. A turbulence generating structure is disposed along a portion of the length of the outer flow channel so as to introduce turbulence into the flow of the heat exchanging fluid flowing along the outer flow channel, thereby improving the transfer of heat energy between the heat exchanging fluid and the Earth along the length of the outer flow channel.
