In order to increase the efficiency of the heating do place the radiators in suitable places throughout the room.
Keep the windows fully open for shorter periods of time. The practice of keeping windows semi-open does let some fresh air in, but leads to the loss of a lot of heat.
Do not completely cool the premises at night but it is advisable to slightly reduce the temperature of the heating appliances.
The doors and windows need to have good sealing.

By replacing an old TV with a new one up to 80% of the electricity consumed by the appliance can be economized.
The old appliances in stand-by mode consume about 150 kWh of electricity on an annual basis. In comparison the new appliances are much more energy efficient.
Turn off the radio or TV whenever you are not actively using them to save money.

We highly recommend the use of energy saving luminaires. An equivalent amount of light can be devised by an energy-saving lamp with a power of only 20W as a 100 W incandescent lamp.
Important: The frequent on and off switching of a lamp adversely affects its service life.

Only when it is necessary preheat the oven. Optimal heat transfer is achieved when the diameter of the pan matches the diameter of the hob as much as possible.
Do fully utilize the residual heat in the hobs by switching them off somewhat before the end of boiling /cooking.

Using a microwave is faster and more energy efficient compared with a hot plate if the portion that requires heating is up to 400g.
However, if you are going to quick fry meat, do use a pan. The special meat dishes, one can place in the microwave, require heating at full power for up to 8-10 minutes.
When preparing coffee the usage of a coffee machine will be 50% cheaper than boiling the water on a hot plate.
Up to 25% energy can be saved when one uses a fryer compared to an electric stove.
Using an egg cooker to boil eggs saves up to 50% electricity in comparison to doing it in a pot on the hob.
The usage of a toaster consumes about 70% less energy than if one bakes slices of bread in the oven.

Do not place refrigerators near a heater or a stove.
Unheated and well ventilated rooms contribute to the lowest electricity consumption.
The appliances with a lower part and the stationary appliances with a ventilation grille must be kept unobstructed - this is how the heat being released from them gets dissipated optimally.
Monitor and don’t exceed the optimal temperature for the refrigeration units in the warehouses: -18° C is sufficient in the freezer and + 7° C are in the refrigerator.
Before being refrigerated and frozen the food should be wrapped properly.
Use the super/turbo mode of the cooling unit only when cooling large quantities of products.
Promptly replace defective doors and sealing.
Regularly defrost the appliances to save energy.

Use the short or economy program if the dishes are just slightly dirty.

The 60° C or the energy saving washing program is sufficient for normally soiled white laundry.
Only heavily soiled clothes need pre-washing.
Load the washing machine to its full capacity.
When you have a few smaller pieces of clothing, which require separate washing, choose short programs. Something to keep in mind though - these washing modes consume twice as much water and electricity as a single run of the standard program.
When the washing program is finished, preferably run an additional spin program - best at 1200 rpm, but as minimum 800 rpm. Only then transfer the laundry to the dryer machine. Dividing the laundry in two halves will consume approximately 30% more electricity – put it all in the dryer at once. It is advisable to clean the air filter (powder mass mesh) on the dryer after each use. The buildup of dirt and particles leads to unnecessary longer drying time.

Taking a shower rather than using a bathtub is recommended. A full bathtub requires approximately 140-180 liters of water and consumes about 3x more energy in comparison with a 5 minute shower. Approximately 1500 liters of drinking water can be saved in addition to the electric energy. Thus the overall energy efficiency of the building gets increased.

Retrofitting is a complex process, whether of a building or of a house. It is a combination of various construction and repair activities - thermal insulation, replacement of window frames, replacement of waterproofing, preventive maintenance of the heating system, etc.

The service life & exploitation period of the building get increased and its main functions preserved and in the case of a family home its overall “life” gets prolonged.
What gets optimized are both the comfort & convenience of the living and the resistance of the building to external atmospheric influences.
There is a reduction of the harmful emissions and the ecological environment is protected.
The costs for electricity and heating are significantly reduced thus increasing the economic efficiency.
An effect thereof is the increase in the property value, resulting in faster return of the initial investment.

By the partial thermal insulation of an apartment unit there is not much freedom, as the thickness, color, material of the adjacent insulation is to be taken into account. More autonomy for designing the exterior exists when renovating family homes.
The most commonly used thermal insulation materials in Bulgaria are stone or glass wool, XPS and EPS.

There are two types of thermal insulation systems that can be used - external and internal. It is advisable to research the advantages and disadvantage of both before proceeding with the renovation.

Probably the most important step in the construction and/or later retrofitting of any building is the waterproofing. It is a required for the optimal functioning of all the other systems and materials so that there is no risk of disintegration. The highest energy saving indicators can be utilized when a complete thermal rehabilitation and retrofitting, including waterproofing, is undertaken.

• Replacement of the window systems (frames, glass)
• Replacement of the electrical installation
• Replacement of the plumbing installation
