The insulation thicknesses normal for this type of single-family home will be optimized further
with a view to the solar heat gains. In case of a current project an insulation (WLG 040) of
5 cm each is provided on the inside and on the outside so that the absorption of solar energy
via the outside walls is perceptible. In addition, a temperature barrier will also be installed
within range of the roof areas which are relatively large as compared with the outside wall
surfaces, so that comforting and controllable temperatures will be achievable via the temperature
barrier also in rooms having no and/or very few outside walls.
During construction of the building numerous measuring heads or probes will again be installed
so as permit documentation by way of the measuring results as to how the reduced
insulation thicknesses and the additional temperature barrier in the roofing influence the corresponding
march of temperatures.
5. Prospects
The advantages of the two approved processes of solar engineering and utilization of geothermal
heat are combined in an amazingly simple form by the utilization of solar energy in
connection with the near-surface geothermal energy. Many examples already realized in all
climatic zones verify the efficiency of this system extremely favourable in regard to both manufacturing
and operating costs. In order to optimize and also to be able to "calculate" this
building technology, further research and development are necessary. The objectives of further
investigations are to gain control of the calculation of heat exchange processes and to
optimize insulation thicknesses. The experience already gained, however, permits an ecofriendly
and economical application of the Terra-Sol building technology already today.
