The main role in a choice of a site for construction is played with soil conditions and subsoil waters. Low bearing{carrying} ability грунтов, a high level of subsoil waters can complicate so a design and a waterproofing of a construction, that construction can become irrational. The Great value has character of a relief as the choice of type of a building and its{his} degree depends on it{him} and from a level of subsoil waters in many respects заглубления. The steepness and orientation of slopes, the general{common} character of a relief define{determine} an opportunity of favorable orientation of the house. The slopes of southern orientation allowing effectively to use for heating of premises{rooms} a solar energy are most preferable. At the big steepness of slopes there is an opportunity of designing заглубленного at home in two levels that is preferable to economy of energy. Same the low level of subsoil waters promotes also.
At designing заглубленных at home in system of existing building it is necessary to consider need{requirement} in обваловке the houses, corresponding{meeting} breaks between buildings (especially if the construction has an internal court yard to avoid it{him} затенения), and also an opportunity of supervision from the next sites. Breaks besides should provide the fire safety, natural illumination{coverage}, инсоляцию, ventilation, creation of an aesthetic environment and conditions for rational operation of a building.
Towering houses have received the greatest distribution. They are erected at a flat relief or with a small bias in the southern party{side} if great volume of dredging is undesirable for economic reasons or is impossible on hydrological conditions of a site of construction. The building should tower above a level of a day time surface of a ground no more than on 30 %. Incomplete заглубление increases by 5...10 % теплопотери in comparison with completely заглубленным a variant (fig. 4, 5).
With one, usually southern, the parties{sides} soil обсыпку do not do{make} a towering house to provide an arrangement of window apertures of the premises demanding natural illumination{coverage}. Premises{rooms} in which natural illumination{coverage} is not obligatory, project{design} in depth. It can be kitchens{cuisines} and dining rooms, if they запроектированы as a part of premises. For maintenance of necessary light front the house should be extended at length. This lack can be eliminated{erased; removed} by an arrangement of premises{rooms} in two levels. The person who is being the house of a towering-заглубленного type, does not lose visual communication{connection} with world around that improves a psychological climate.
