RENEWABLE ENERGY SOURCES FOR THE PROJECTZones of wind in Poland

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)

Realistically, you can get 400 – 700 KWh/m2 It gives you coverage of needs for:

hot water – 60 – 80% central heating – 10 – 20 %

Ventilation must be designed so that it draws a minimum of:• from the kitchen from 30 do 70 m3/h (depending on whether the kitchen with a window, the number of people, kind of stove), • from the bathroom 50 m3/h, • from a separate toilet 30 m3/h, • from a room without windows (eg. dressing room) 15 m3/h, • from living rooms (in some specific situationns) 30 m3/h.
