1. General information

1.1. Investment designThe structure is family house dimensions 12 x 8,2 m with basement ground floor and garret.

Main target in design was low energyconsumption family residence.

2. Bearing system

2.1. General descriptionThe structure is family house with: concrete basement, wooden structure with steel frame of the ground floor and wooden structure of the garret.

Prefabricated outside walls as timber frame.

2. Bearing system

Outside walls as timber frame with the final configuration:

1. Contact facade: 0,6 cm2. Fasade plate: Agepan THD 6 cm3. Timber frame structure with blown-in wood fiber insulation: 16 cm 4. OSB plate: 1,5 cm5. Instalation channel with blown-in wood fiber insulation: 5 cm6. 2 layers of gypsum plaster board: 2 x 1,25 cm

2. Bearing system

2. Bearing system

3x steel beam on steel columns due the earthquake loading, HEA 160, S235JR

2. Bearing systemRoof support.

3. Actions on structure

Applied actions on structures for the calculation:

1. Dead load2. Live load p = 2.0 kN/m2

3. Snow s0 = 1.27 kN/m2

4. Wind on roof w0 = 0.16 kN/m2

5. Wind on wall w0 = 0.45 kN/m2

6. Acceleration of the foundation 0,20 g

3. Actions on structure

Applied actions of structure on the foundation plate.

4. Erection

Wooden structure and steel reinforcement of the ground floor is placed on the reinfored concrete plate (15 cm) covered with the hydroinsulation (1 cm), followed with thermal insulation XPS (20cm), PE foil and reinfored concrete plate (20 cm).

Load carrying outside walls were prefabricated frames covered with OSB plates on one side.

Wooden structure of the garret and roof.

4. Erection

Thermal insulation of the foundation plate

4. Erection

Assembly of the structural elements

4. Erection

Covering with the fasade plates.

4. Erection

Final shape.

5. Technical parameters

Ground plan size: 12 x 8,2 mNumber of above-ground floors: 2

Type of roof construction: 35º

Construction of external walls: Timber frame with OSB on the one side and fasade plates on the other side filled with the blown-in wood fiber insulation.

Reinforcement of the ground floor: 3 x steel beam on two steel columns for the earthquake loading, HEA 160, S235JR

Thermal transmittance for external walls:

U = 0,13 W m-2 K-1

Thermal transmittance for roof: U = 0,10 W m-2 K-1

Heat loss at project temp. -16oC Qloss = 5.370 W.
