The nearly passive building

The nearly passive building

The building has not got the traditional central heating.

The energy consumption is 20 % less than in traditional house

The cost of building is not much higher than the traditional one

The cost of energy is 5 times less

The comfort of life is higher than in traditional house


The nearly passive building

The average annual energy consumption

in kWh/m2 of the surface in the buildings

Which were built in Poland in different periods

(acording to changing rules) and in the currently

built energy saving buildings.

W kWh/m2/year

The energy saving

20-40

The flat 70 m2


The nearly passive building

The qualities of the energy saving building

Location– insolation, shields, green area

The form of the building–

Walls, roof, floor–thermal layer of 20-30 cm, elimination of thermal bridges

Windows and doors–hermetic,small wastes

Shutters or outer blinds

Ventilation:gravitational, mixed, mechanical

Warm water– solar collector

The test of tightness of the building+thermo invading camera


The nearly passive building

Heating

Low temperature (e.g.on the floor)

The thermal pump

Heat ground exchanger

Recuperator

The fireplace

gas/oil/liquefied gas/electrical/local provider

Mixed heating


The nearly passive building

How does it work?

Cold air

Cool air

Warm air

The used air

The heated air


Recuperator

Recuperator

Exhaust ventilator

Fresh air

The used air

Intake ventilator

Recuperator —it is the device used in the systems of ventilation, which enables to recover the thermal energy from the air which is blown outside of the building Recuperator is the thermal exchanger. Different types of recuperators are used to recover the energy from the exhausted and intaken air.

The work of the exchanger in winter

The continuous work for 24 hours-

the flow of the air is 2/3 of the output

The recommended method of installing the window in the passive house

insulation

window

The fastening anchor

The wall must be monolithic


The nearly passive building

Thanks to such installation of the window we can use every material for the wall (the most important thing)

My changes to the passive house

A. Jurkiewicz

  • Tightness of the building

  • The lack of additional air ventilators

  • Insulation of walls +accumulation of walls

  • Insulation of the ground floor

  • The natural blinds- ivy+ artificial ones

  • The electrical outer blinds

  • Elimination of the thermal bridges

  • The supportive heating (mats)

  • The electrical floor heating

  • Mixing buffor

  • Emergency aggregate

  • The work of recuperator winter/summer

  • The cventilation cables

  • Full automatization

  • The fireplace with the closed buffor for combustion

  • Solar collectors(cwu – warm water)

  • The cost of the building of the house(windows; 25 cm; recuperator; automatization) is comparable with the cost of traditional house

The presentation has been made for the FOCUS project

Based on the materials retrieved from MrA. JURKIEWICZ and photos taken during the trip to the nearly passive house
