Consumption of energy by sector

• Decreasing of energy consumption
• in 1990 - 1200 PJ
• in 2005 1040 PJ
• Energy import dependence of Hungary 78.
• The most important import rate of the natural gas
  - 82

Isolation

• 60 of the total energy we use in our households
  is used for heating. While 5,5-5,8kg insulator is
  used in the countries of the EU individually a
  year, we use only 1,2kg in Hungary. Though
  insulating materials are only cost 10 of the
  whole cost of a construction, Hungarian builders
  are tend to save on it, despite the fact, that it
  would be repaid in a few years. The most
  important thing would be the isolation of the
  roofs, as hot air usually goes up, so in those
  houses in which there is no isolation, 60 of the
  heat goes out through the roof.

Some useful tips how to cut back on energy
consumption in your house
17

• Switch your thermostal 1 degree lower!
• Install hollow wall-isolation!
• Isolate the attic!
• Energy-saving lightning
• Heating and hot water
• Energy-saving washing products
• Buy products with ESR signal/logo
• Dont use more hot water you need!
• Dont use cars for short trips!
• Dont leave TV, DVD player etc. switched on!
• Double coating, secondary glazing
• Correction of the cover
• Isolation of the floor
• for smaller ice cubes
• Isolation of the container and the tube

18
Some crumbs how to save energy

• Should the surface of the electric store be
  smaller or bigger than the bottom of the saucepan
  you put it on?
• Is dirty oven able to reflect less or more heat?
• Is it necessary to switch off the oven before our
  meal is ready?
• Why cant we put hot meal into the fridge?
• Why is it bad if our refrigerator is iced?
• What is useful to visit before buying a fridge?
• Why is it useful to empty the dustbag of the
  hoover before using it?

19
Questionnaire (1-3)

• When was your house built and from what kind of
  material?
• a. from traditional material before 1994
  
• b. after 1994 according to the regulations
• c. I dont know
• Have you ever done any thermal isolation works on
  your estate?
• a. yes
  
• b. no
• c. I didnt feel the need o fit
• d. I didnt have the possibility
• How do you produce hot water?
• a. with the help of gas
  
• b. with the help of electricity ( night tariff)
• c. PB gas
• d. in a mixed way

20
The result of questionnaire

• We answered 100 family.
• 75 of families answered that their house was
  built from traditional material before 1994
• 56 of families have done some thermal isolation
  works on their estate
• 44 of families produce hot water with the help
  of gas

21
Questionnaire (4-6)

• What do you heat with during the heating-season?
• a. wood
  
• b. natural gas
• c. electricity
• d. oil
• Do you use renewing energy sources in order to
  save
• energy?
• a. yes
• b. no
• c. what is that?
• Are you interested in the rational energy
  utilization?
• a. yes
• b. no
• c. Ill be interested in it

22
The result of questionnaire

• 56 of families heat with natural gas during the
  heating-season
• 93 do not use renewing energy sources in order
  to save energy
• 68 of families are you interested in the
  rational energy utilization

Higher capacity

• Floor-heating systems are only able to
  exotherming 80-100W/m, because the temperature of
  the floor can only be 29 degree, because of the
  sensitivity of our feet and health reasons.
• At the same time, by using wall heating, 45-50C
  degree hot water circulates in the 6mms outer
  diameter polyethylene tube.
• Thats why the surface temperature of the wall
  is much higher ( 38-40C), so the 200-240W/m
  exotherminity can also be guaranteed.

Energy-saving

• The opportunity to reduce the temperature with
  the help of the wall heating means 12-15
  energy-saving. Moreover as the temperature of the
  air in the room is much more equal in vertical
  direction than in the case of the convectional
  heating, the further saving is about 5-8.
• The regulation is much quicker compared to the
  floor heating, which also means 5 saving.
  Despite the fact that by heating the outer walls
  there is heat loss into the outer space, in
  total, we use less energy.

The compact flourescent tubes and traditional bulb
28
Do you know that light intensity is not in equal
with the power?

• The radiance of a 100W bulb is exactly the same
  as 6 pieces of 25W bulbs, so using a
  many-branched chandelier is an energy-wasting
  method. The compact flourescent tubes have come
  to the place of the traditional bulb. This
  compact fluorescant tube is a bended tube. It can
  be used instead of the traditional bulb, moreover
  it saves 80 energy inspite the fact that it
  radiances the same quality of lightning. Its
  length of life is 8-10 times longer.
• The heater filament bulbs change the 90 of the
  adopted amount of energy into heat, and only 10
  is devoted to the radiation of light. They are
  rather used for heating, not for lightning.
  Despite, the compact flourescent tubes change 50
  of the adopted energy to light. That is why a 20W
  compact tube radiates the same light as a 100W
  bulb with heater filament.

The project was successful because the families
who were participants in this job saved one-third
energy.
