1 Let’s start from ourselves

2 Why do we save energy? The answer is the only one:…..For ourselves and indirectly? -For the Earth (greenhouse effect?) -For fulfillling UE norms and requirements(3*20) -For our countryside (Czorsztyn) -For money -For the future generations -Because of our own reasons

3 Energy at home and at work is consumed for: cooking lighting,washing,TV, computers (electricity) Warm water heating Air conditioning The machine drive Energy for industrial technologies (e.g. biscuits covered with chocolate)

4 while cooking -Inductive board instead of ceramic one -Pressure cooker -Boil as much water as you really need Doyou know how many times you should pick up 1 kg of sugar for the height of 1 m to have a mug of hot tea? Answer: about _ 20_ thousand times Remember! Boil as much water as you really need! To diminish the consumption of energy You should use

5 In lighting The bulb (wolfram)- only 15% energy is sent as the visible radiation, the rest is the heat waste You should use 1. Halogen, mercury, glow tubes –savings from 50 to 80% of electricity 2. Switchers with sensors 3. The natural light To diminish the consumption of energy

6 Washing machines and fridges You should Wash in the low temperatures Use the warm water instead of the heater Use the full capacity of the washing machine defrost the fridge Close the fridgeuse the washing machines and fridges of energy saving types A To diminish the consumption of energy

7 We save the running water - Perlator (the mixture of water and air) e.g. The tap uses 10-15 dm3/min, and perlator 5-8 dm3/min -One handled tap: 25% of savings -Thermostatic tap: 50% of savings -Untouched tap: 60% of savings Additionally: The nocturnal limits for the circulation(the clock of circulating pump): 5% Thermostatic valves: 10% Thermostatic valves + circulating pump: 15% Insulating of the pipes with the running water: 5% Water meters Shaving, toothbrushing Why does the running water have the temperature of 60 Centigrade?

9 Heat receiver Pipe made of copper The double wall made of glass The hot steam goes up and the cool steam condenses on the bottom of the pipe

10 The collector’s effectivness Months of the year The amount of the solar radiation

11 The typical set of collector for the warm water 1 3 2 4 6 7 5 8 strych 4-6 bar

12 in HEATING: -Thermostatic valves (they lower the temperature about 1 Centigrade =6% less energy) -The weather regulator -The weekly/daily regulator -Methodology of airing the flats -check the activity of ovens (heat curve) To diminish the consumption of energy use

13 na grzejniku w pokoju The heat curve 90/70 Supply return The temperature outside The temperature of heated water

14 Let’s count on ourselves if we use properly : Running water 10% (shaving,tooth, perlator 12 zł) 6l/day=2m3/year=1GJ/year= 50kg C=100kgCO 2 Airing 4% 4%*50GJ/year= 2GJ/year= 100 kg C= 200kgCO 2 Thermostat 6% (jumper) 6%*50GJ/year= 3GJ/year = 150 kg C = 300kgCO 2 tea 0,2l/tea*10=2l/day=1GJ/year=50kgC=100kgCO 2 The result: 7GJ/year=350kgC=700kgCO 2 Within the year we can save… ?.. If…

15 Go on counting 7GJ*50 zł = 350 zł savings, so we buy: Bulbs 10 items * 35 zł = 350 zł 80W*10 items= 800W*2000h/year=1,6MWh (800 zł) =6GJ/year 6GJ*3 (electricity) = 18 GJ = 900 kgC = 1800 kgCO2 PLN=800zł-350zł=450zł 1 person = 25 GJ/year = 1250 kgC = 2,5MgCO2 How many people are there in the room? 100 people = 2500 GJ = 125MgC=250MgCO2=45000 PLN 2500 GJ = heating of 2 schools (after insulating) statistically The efficiency of Polish power stations 33% ton

16 Insulating of the roof 12 % Walls 15% Central heating – 12% Intake ventialtors 5% Savings altogether are about 50% At present energy savings are 0,9 GJ/m2 (300 kWh/m2/year) In future no more than 0,5 GJ/m2 Costs: 90.000 zł/2 = 45.000 zł Cost: 1.000.000 zł Thermal centre 10%

17 Intake ventilator

18 The relative humidity The flow

19 Topics for discussion cogeneration The thermal pump ESCO agreements white, green, yellow, red certificates The trade with CO2 emissions The thermomodernisation programs

20 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 MARCH 2010 IO
