Method of constructing passive that reduce heat loss of a building, as well as the costs and consumption of materials

Abstract

The method of the construction of passive foundation and, in particular, of connecting them with walls is characterised in that in order to improve the thermal insulation so as to limit the heat losses for a building or to simplify the structure or to reduce the building costs, the surface of the foundations or the contact surface of building materials/structural foundations ( 2 ) and building materials/structural walls ( 3 ) is purposefully reduced i.e. by being partly replaced with a column structure (made i.e. of reinforced concrete) ( 6 ) and partly with horizontal thermal insulation ( 7 ), whereas thermal insulation, which is an important objective of this operation, is placed under the walls of the building or between the foundation and the walls in places where the continuity of the foundations (walls) is limited/interrupted (between the columns). Horizontal insulation is therefore located under a considerable part of the walls, except for the surface of the poles.

1 . The method of the construction of passive foundation and, in particular, of connecting them with walls is characterised in that in order to improve the thermal insulation so as to limit the heat losses for a building or to simplify the structure or to reduce the building costs, the surface of the foundations or the contact surface of building materials/structural foundations and building materials/structural walls is purposefully reduced i.e. by being partly replaced with a column structure (made i.e. of reinforced concrete) and partly with horizontal thermal insulation, whereas thermal insulation, which is an important objective of this operation, is placed under the walls of the building or between the foundation and the walls in places where the continuity of the foundations (walls) is limited/interrupted (between the columns). Horizontal insulation is therefore located under a considerable part of the walls, except for the surface of the poles. 
     
     
         2 . The method according to  claim 1  is characterised in that the horizontal insulation or the reduction of the surface area of the walls may be made at different heights, in particular under the building wall, but also between the continuous footing and the foundation wall, at the height of the foundation wall or the height of the building wall. 
     
     
         3 . The method according to  claim 1  is characterised in that it is possible to completely eliminate the foundation walls and consequently their insulation and cover, and to replace the walls with a column/skeleton structure laid i.e. on continuous footing, or to reduce the amount of foundation walls, i.e. by lowering their height. 
     
     
         4 . The method according to  claim 1  is characterised in that foundation walls are replaced with only thermal insulation or other type of partition (metal sheet or mesh, precast elements) in order to reduce the transfer of heat or the amount of rodents penetrating into the area under the floor. 
     
     
         5 . The method according to  claim 1  is characterised in that the skeletal structure can be replaced with walls whose cross-sections are smaller, or with walls not extending along the entire length foundation but placed only as spots/sections. It is a matter of nomenclature whether these structures are defined as columns or walls. 
     
     
         6 . The method of constructing foundations according to  claim 1  is characterised in that it can include additional reinforcements, in particular to improve the resistance to bending of the column structure. 
     
     
         7 . The method of constructing foundations according to  claim 1  is characterised in that it can be used in connection with buildings and foundations of any shape. 
     
     
         8 . The method of constructing foundations according to  claim 1  is characterised in that the foundation can be of any kind i.e. as spots under the columns, without having to lay continuous footing. 
     
     
         9 . The method of constructing foundations according to  claim 1  is characterised in that the solution can be used for a variety of structures in the construction industry, i.e. in skeletal, metal, wood structures, or other light structures, or in industrial construction. 
     
     
         10 . The method of constructing foundations according to  claim 1  is characterised in that the structure of the foundations can be made of all sorts of materials including i.e. steel. 
     
     
         11 . The method of constructing foundations according to  claim 1  is characterised in that the cross-sections of columns or foundation walls can be of various shapes at different heights (e.g., can be conical or stepped), for example with a larger cross-section at the bottom of the column (area of contact with the footing) to provide better stability, and with a smaller cross-section at the top to transfer less heat or lower the costs of manufacturing.
