Buildings must, in their functional purpose, respect (essentially given) normalized difference between desired internal temperature and real temperature of the external environment. For residential and service buildings we ask what the largest enclosed space with the least possible surface of casing, on the contrary for cooling buildings, we demand the greatest possible surface, regarding the necessary volume of buildings. From the energy-saving or a technical point of view, in the buildings it essentially depends on the ratio of\content of the surface of the building envelope to his enclosed space". Complementary of this basic requirement is the second criterion, namely respect for the thermal insulation shell of objects. If the thermal insulation properties of the object coating material are considered to be a matter of physics (especially thermodynamicsthrn proportional-geometric properties are pure stereometric indicators. The submitted papers deal with these spatial geometric properties of some elementary shapes of objects, in terms of their optimal functional usability, and discuss mostly inevitable contradiction between their thermal energy advantages and associated spatial or architectural negatives (in terms of material savings or in terms of production-implementing).
