General part

The course work is performed on the basis of a task containing schematic drawings of a residential building with basic construction parameters .

The building is 2-story with the orientation of the main facade on the South Caucasus. The ceiling height is 2.7 m.

The roof of the building is made of rolled materials.

External doors - double blind with a tambour.

Windows and balcony doors according to SNiP II379 *.

External walls: 1st layer: texture layer (concrete on natural stone gravel) 50mm thick;

Layer 2: foam plates GOST 2091675;

Layer 3: texture layer (concrete on gravel made of natural stone) 50 mm thick.

Construction district - Lviv.

Relative humidity in the room is 55%.

The heating system is a water double-tube with an upper location of the supply line.

Heating devices - radiators of M140AO type.

Heat supply source - urban heating network.

Coolant - water with parameters TG = 1450С, TO = 700С.

Pressure at the entrance to the building 40kPa.
