For a longer time I have applied myself to buildings, which have influenced human health. New knowledge has enabled me to complete some information that is why I have returned to this object. Like objective instrument I have made an octagonal plot of construction whereat I have demonstrated energy situation inside and outside the construction. I have chosen the octagon because it is easy to find out from it zonal configuration of two opposite walls and even zones of square and rectangular plot. Zones of circular construction can be located just as easy. In most of cases must be completed the inner raster by zones of roof. It is impossible to map them into the plan because it will become unnoticed. So we will take into account that inside a building the raster is more concentrated. Along the experiments with octagonal plot I have understood the function of small circular buildings called rotundas. Semicircular outbuilding on one of them has indicated it to me. Builders of rotundas known energy quality of circular plot and when they needed an expansion of energy, they solved it by semicircular outbuilding - by apse. By the half graph of octagon can be proved the energy of apse, which we can find on ritual constructions of all kinds. The rotunda functioned so like family serve unit - people obtained there the energy. In most of churches the apses pile up energy of altars. It is interesting that apses have not the origin in basilicas but it is possible to find them even on the objects from much elder era. For ritual construction architects chose places with larger concentration of energy, e.g. in inner bend of watercourses (graph of energy in inner and outer bend of watercourses is identical with a half of graph of octagon), in the place of crossing energy zones or above deposits of metal ores, minerals etc. Characteristic signs of certain sacred places on the world are replicate reconstructions at the identical place. On some Gothic cathedrals is evident that construction of towers was not finished. From that follows that along construction the constructors watched its energy and after achievement of planed value the mass of towers could not be magnified. Experimentally tested finding of my research is the reality that every mass, including organisms, has its fundamental energy value. If the mass falls to contact with energy component of major charge, then takes from it energy. By organisms it is identical, cellules receive energy from inner overstrain of buildings. Physician biophysics has mentioned that cellular membrane has the capacity microfarad for square centimeter. The total area of cellular membranes creates so certain reservoir of energy for electronic of human body. It is generally known that any electronics is constructed for certain tension and a deviation of it makes breakdowns. So we can presuppose that to resembling effect will happen in human body - changes on cellules will evoke health disorders, too. From it has followed that the ritual buildings of all religions from menhirs, dolmens, cromlechs, mounds, till cathedrals, mosques, synagogues and other buildings were built for stabilization of tension on cellules and thereby for repair of human health. Historic buildings by the influence of power stations, distribution of high voltage, large towns and other sources, obtained larger energy value than was primary proposed. Over modern buildings the designers have been not even engaged by energy of constructions. Statistics has indicated some buildings like "cancerous houses" and has called attention to some hospitals with major mortality. But that cannot be judged by empirical method, thereto will be requirement of new measuring instruments.
