EFFICIENCY IN THE DWELLINGS
We do not seem to get the expected benefits from the heating, cooling and illumination systems and devices that we use at homes despite to payment of very high costs for the energy consumed in their operations. There are three basic reasons for this. The first reason is the very high energy prices in our country especially for electrical energy and natural gas. The second reason is the inferior efficiency of the heating, cooling, illumination system and devices that we use at home and unconscious operation and use of these to cause efficiency reduction. As for the third reason is being the improper architectural design and insulation of our dwellings to provide protection against the cold and the heat and to provide sufficient illumination.
Approximately one third of the energy consumed in our country; is used with the purpose of heating, illumination and operation of the electrical equipment in the dwellings. A very big portion of the energy requirement of our country is imported as petroleum, coal and natural gas and the dependency on abroad are gradually increasing.
Therefore, as consumers; we shall be making a big contribution to the protection of our environment as well as providing a great benefit for both family’s and country’s economy, when we pay attention to the efficiency and energy saving aspects at our homes, when we select and operate the systems and devices to be used at home consciously and when we take the necessary precautions for the insulation of our homes.
THE PROVISION OF HEAT INSULATION AND ENERGY EFFICIENCY IN DWELLINGS
- The infiltrations from the windows and the doors must be checked. The points of infiltration must be sealed off with sponge and similar bands.
- The loose window panes must be secured to the frames by adhesive bands or paste or must be banded. There shoul be no void space between the window frame and the wall. If unable to cover the cost of installing double pane windows, some more loss of heat may be prevented by covering the windows with transparent nylon sheet during the winter months.
- The window frames that cannot be repaired must absolutely be changed.
- During the winter months curtains of the windows must be kept shut (in a manner not prevent heat circulation over the heating devices like radiators etc.)
- During day time the curtains of the windows that receive direct sunlight must be opened.
- The technologies that make use of energy in an efficient and effective way must be applied; one must make sure that in newly constructed buildings the TS 825 standard for the rules of heat insulation has been complied with.
- In case of non-insulation or insufficient insulation; the roof, the walls and the floors that are adjacent with unheated places must be insulated. When making the insulation; the suitable material for the regional climates indicated in TS 825 standard, must be chosen.
It must not be forgotten that with proper insulation in the dwellings, the heat loss can be reduced at least by the following rates:
- When the insulation of the roof is made: ~20%
- When the outer wall insulation is made: ~15%
- When the window-door insulation is made: ~15%
- When the precautions against leaks are taken: ~10%
- The hot water pipes traversing from unheated areas must be insulated.
- The heat emanating from the radiators by convection and radiation, heats the wall behind the radiator. In order to prevent the heat loss to the outside, heat insulation boards covered with aluminum folios must be placed between the wall and the radiator and the tops and fronts of the radiators must not be covered even for decorative purposes.
- The dwellings with square plan floors are more energy efficient than rectangular ones due to having less areas to loose the heat.
- If possible the sun panels must be utilized for the provision of hot water.
- The heating systems and devices to be used in dwellings must be chosen to provide the highest energy efficiency and savings.
- The device capacity (stove, combi, electrical heater, flat heater, boiler, air conditioner etc.) must be selected in accordance with the requirements of the heated/cooled area. While determining the device capacities, in large areas or big cities the geographic conditions and the structures of the construction material must be taken into the consideration.
- The devices with lower electricity and fuel consumption, higher efficiency must be preferred.
- Environment friendly devices (devices with low combustion emissions) must be kept at the forefront.
- The combustion and heat efficiencies (rated heat capacity), cooling and heating capacities (air conditioner) of the devices must be high.
- In the catalogues and brochures of the devices both the “combustion efficiency” and the “heat efficiency” must be indicated separately.
- The heater must possess the property of “not going out” in windy weathers.
- The heater/cooler which has the electronic temperature control (thermostatic) must be preferred.
- The silent working devices must be preferred.
- The electrical devices such as refrigerator, washing machine, and dish-washer must be selected from the A Class types.
- The electrical devices such as stove-furnace, electrical vacuum cleaner, iron having the maximum efficiency in energy utilization, must be preferred.
- In the illumination the electric bulbs with low energy consumption, with long life and compact type must be used.
