Tips for Energy Efficient Buildings

·         Insulation in windows and doors should be increased.

The windows and doors are causing the loss of one of the four heat in your home. Heat loss in windows with double glazing or heat is reduced by half. In this respect, building materials with a high saving rate should be preferred. Sealing in windows and doors is important in heat loss. To identify air leaks; If a burning candle is moved around the edges of the window and the candle flame is moving to the left or right, then there is a leak in those areas. Window strips and sponges should be used to prevent air leaks.


·         Attention to curtain use.

In the winter months, the curtains in the windows that directly receive the sunlight should be open, while others should be kept as closed as possible. Pay attention to the curtain lengths as long curtain radiators will block heat flow.

·         Attention should be paid to roof insulation.

As the warming air rises and tries to escape from the roof, the roof must first be insulated.

·         Heat loss from the radiator backs should be avoided.

As a result of studies on thermal losses made with thermal cameras, it is seen that there is very little heat loss on the insulation side of the building and there is a lot of heat losses behind the radiator and windows on the uninsulated side. The heat from the radiators through convection and radiation heats the wall behind the radiator. To prevent heat loss to the outside, aluminum foil covered heat insulation panels can be used on the radiator backs.

·         If the temperature of the rooms increases, the radiator spout may be turned off instead of opening the windows.

The buildings have large temperature differences due to sunlight, especially on the north and south facing sides. If the temperature of the rooms increases, the radiator spout can be turned off instead of opening the windows.



·         Thermostatic radiator valve should be used in radiators.

When the room temperature is adjusted with the thermostatic valve, the water circulation in the radiator is cut off and the energy is saved by preventing the room from heating more than normal value. To increase the room temperature by 1 ° C, about 6% more fuel is needed.

·         Inspection of the integrity of declared insulation values and application values during the construction phase should be ensured.

The materials used in the buildings do not have the isolation properties declared in the majority. In some of the materials with appropriate insulation level, incorrect or incomplete application due to inadequacy of education cannot give expected performance. In this respect, the educational implications of construction intermediaries must be removed.

·         Designers and engineers should pay attention to energy saving and renewable energy usage in buildings.

To educate architects and engineers who do not pollute the environment and who are interested in producing all kinds of renewable energy (wind, sun, thermal, bio, hydro etc.) that do not cause CO2 emission as much as possible and design energy saving by passive and active energy methods in building designs. and the use of renewable energy should be emphasized.

·         Mechanical systems play an important role in energy efficiency.

By creating automation scenarios, it is necessary to make the systems work in compliance with the projects and scenario by carrying out the tests of the commissioning, measurement and verification of the systems.

·         Buildings and insulation materials to be used in building construction should pay attention to the standards.

Care should be taken to ensure that the construction and insulation materials U and SF values to be used in building construction are equal to or less than the thermal conductivity values given in addition to TS 825 with high solar control glass and joinery systems.

·         Energy efficiency should be considered in heating system designs.

Today, when the building shell is well insulated, temperatures can be made to be 70/55 ° C or lower, while formerly heating system designs are made at 90 ° C boiler outlet and 70 ° C boiler return temperatures. In this way, boiler sizes are getting smaller, their costs are decreasing, their productivity is also increasing. The energy consumption can be reduced by insulation of the distribution pipes and collecting pipes and valves in the basement of the heating installation.

·         In order to use energy efficiently in houses, it is necessary to reduce heat losses, i.e heat insulation.

External heat insulation should be preferred on the walls. Thus, the heat storage capacity of the wall material is utilized and the risk of choking is reduced in the wall section as well as in the wall interior due to the presence of heavy mass at high temperature.

·         Devices with an energy label rating of at least "A" should be preferred on new purchases.

·         There should be no objects blocking the heat flow on the heating devices such as radiator or fan coil.

·         Radiator and fan coil maintenance should be done before the heating season.

·         Temperature or temperature control systems should be used to keep the ambient temperature constant.

·         The radiator can be registered with the radio / thermometer system which calculates the heat consumption value by means of surface temperature, room temperature and water flow measurements.

·         Care must be taken to ensure that buildings comply with energy efficiency standards in architectural design.

·         Implementation should be made according to the projects arranged according to the standards.
