Type of home : bungalow Usable floor area : 24,20 m² Rate of energy demand for heating : 14 kWh/m²

 Living room - 10,00 m²  Kitchen and hall - 11,78 m²  Toilet - 2,42 m²

In Poland, the cheapest method of obtaining a relatively large amount of energy for the house Requirements for small wind turbine: 12 m mast or tower within the existing building no obstacles to the west (the most frequent winds in Poland)
