1. Receiving digital data:
Measuring devices must have a communication system in accordance with the standards. Thanks to this communication system, users are not disturbed by entering the house, an appropriate communication system is established and the consumption values of the measuring devices are read regularly without any intervention or error. More than 90% of the projects in our country are read via digital communication.
2. Manual data acquisition:
If a communication system has not been established for the measuring devices and if there are old, incomplete or non-standard applications, the values of these measuring devices can be read and recorded manually by a personnel. In projects with this system, human error, user discomfort and slowness may occur.
Daf team, which has established and commissioned the measurement and communication systems of many large and small projects with centralized measurement systems in Turkey, always reads the meter values with the most suitable application for your project. Provides the necessary support for the relevant installation and development for deficiencies.
In the heat cost sharing system, savings are indisputably provided for the entire building.
Natural gas rates of buildings that prefer this system have decreased by at least 20% and at most 60% in the old system.
These figures have been determined as fixed by our company as a result of comparing the monthly natural gas expenditures on the natural gas bills of the buildings transferred to the system before the transition to the system, and the expenditures after the transition to the system.
As stated in the answer to the 3rd question, savings are achieved for the entire building in the heat expense sharing system. However, if you do not take any savings measures in your individual use, the share calculated for your flat from the building’s main bill may be higher. In this case, we recommend that you review your usage and save more effectively.
On the other hand, if you are living on a new site, if the session rate in your project is below 50%, the session rate may need to be above 70% to achieve the real savings rate.
By law, space temperatures cannot be set below a minimum of 15 C. This is also not a suitable method for saving money. The cost of completely cooling and reheating the home is much higher than the cost of keeping it warm.
In addition, in terms of equity, this practice causes our neighbors to consume more energy than necessary due to the heat loss caused by this apartment.
Article 18 of the Condominium Law No. 634: Flat owners are mutually obliged to comply with the rules of correctness, especially not to disturb each other, not to violate each other’s rights, and to comply with the provisions of the management plan when using their independent sections, extensions and common areas.
Central Heating Expense Sharing Regulation No. 26847 Official Gazette Article 5- (6) The space temperatures in the independent sections heated by central systems are adjusted to be at least 15 ˚C.
According to our legislation, 30% of your building fuel expenses are distributed as heat expenses arising from common areas, system losses, minimum heating and operating expenses, according to the indoor usage areas of all independent sections, regardless of whether they consume heating or not.
Additionally, according to our legislation, space temperatures do not need to be adjusted to a minimum of 15 C. For this reason, the heating system of the flat cannot be completely turned off. As a result, the share of heating consumption to provide 15°C temperature in your empty flat will also be accrued as an expense to your flat.
If the site management board has taken a decision on the subject for independent sections where the heating system is turned off, an equivalent consumption calculation can be made for these independent sections.
This is valid for projects using heat stations. Since the sanitary hot water is heated by the heat station in projects with a heat station, the heating expense you pay in the summer months is the equivalent of the heating energy consumed by the heat exchanger in the heat station to heat the water.
Firstly; In our calculations, it is not possible for us or your site-building management to determine a fixed unit price.
Our company does not sell or supply energy or water and does not issue invoices. Our company only makes the necessary calculations to distribute the collective invoices issued by energy and water suppliers such as İGDAŞ, İSKİ, BEDAŞ to the central system of your building to the flats in accordance with the legal legislation and management plans.
Unit costs stated on the Expense Sharing Documents; It is calculated by dividing the invoice amount issued by the supplier company to your building by the total consumption we measured, and is stated to inform the consumer and ensure control of the account.
As a result, expense sharing calculation is based on a sharing logic.
Unit cost is found by dividing 70% of the building heating expense by the total energy consumed by all flats in the building during that period. Therefore, the residence rate in the building varies depending on many variables such as building insulation and the number of days of the semester.
Let’s think like this: Natural gas, whose kWh unit price is 0.15 TL, is burned in the building’s boilers and heats the installation water. The kWh value we measure is an energy value calculated according to the inlet and return temperatures in front of your door. In other words, the water heated in the boiler has lost its energy by the time it reaches your apartment. This applies to the entire building. Due to the efficiency of the boiler and mechanical installation of the block you live in, the losses between the hot water heated in the boiler and reaching your flat affect the cost of heating energy in direct proportion.
We can also think like this: For example, we live in a building with 100 flats. The capacity of the boiler is calculated for 100 flats, but our building is new and only 10 flats can accommodate it. While the hot installation water heated in the system circulates in the mechanical installation for 100 apartments and loses energy, only 10 apartments use it. Therefore, you can estimate how much the energy cost has increased here.
Each block’s indoor areas, geographical conditions and location, gas and water meters, number of occupants, and hot water and heat usage by residents are different. In addition to this difference, the meter reading dates of the providers also vary, sometimes meter readings are not made due to insufficient consumption and/or other reasons and the bill for that period is received in the following period. In this case, the unit price may be low due to the invoice not included in the sharing specified in the regulation, and the unit price may be high in the next month due to the inclusion of the previous month’s invoice.
Expense statement is not an invoice and cannot be used as an invoice. Expense notification is a document containing measurement values regarding your flat’s share of the fuel bill received by your building’s central system and how this share is calculated. It can be considered as an extract.
If sanitary hot water is also provided centrally in a central system, this is provided by two different systems that vary depending on the mechanical installation structure of your building. In both systems, common expenses are calculated in summer and winter.
The first of these is the sanitary hot water heating system with boiler tank. In these systems, common expenses during the summer months are calculated with a function in the legislation.
The second system is the heat station system. In the heat station system, as in the 12-month heating system, 30% of the total heating expense of the building is shared as a common expense in proportion to the closed usage areas of the independent sections.

No. It is not correct to evaluate the meter values as they are for an accurate bill sharing.
Smart measuring devices, due to their technology, record all measurement-related information and store it in their memories. All values measured according to usage areas should be analyzed in many aspects such as manipulation, malfunction, leakage, leakage, high consumption, and expense sharing calculation should be made as a result of these analyses.
On the other hand, data analysis also provides important information for the energy efficiency of the building.
The constantly updated software infrastructure, developed by Daf Energy Management with its expertise and experience, automatically performs these analyzes and ensures that expense sharing is done accurately and fairly.

Article 7 c) In buildings with central heating systems, central or local heat or temperature control devices and systems that allow sharing of heating costs depending on the amount of heat usage are used. Projects prepared contrary to this will not be approved by the relevant authorities.
PROVISIONAL ARTICLE 6 – (1) Subparagraph (c) of the first paragraph of Article 7 of this Law shall not apply for five years from the date of publication of this Law, for buildings that existed before the publication date of this Law and buildings that are under construction but have not yet received a building use permit. This period expired in May 2012.
CONDOMINIUM OWNERSHIP LAW NO. 634
Article: 42 (Amended 4th paragraph: 5627 – 18.4.2007 / art.16) Upon the request of one of the flat owners, thermal insulation, fuel conversion of the heating system and conversion of the heating system from the central system to the individual system or from the individual system to the central system, the number and land of the flat owners. It is made upon the decision made by the majority of the shareholders. However, in buildings with a total construction area of two thousand square meters and above, the conversion of the central heating system to an individual heating system is made upon the unanimous decision of the flat owners in terms of number and land share. The expenses of the joint works to be carried out in this regard are paid according to the land share ratio. The procedures and principles regarding the sharing of heating expenses in central heating systems are regulated by the regulation to be put into effect by the Ministry of Public Works and Settlement.
REGULATION ON SHARING THE HEATING AND SANITARY HOT WATER EXPENSES IN CENTRAL HEATING AND SANITARY HOT WATER SYSTEMS
ARTICLE 1 – (1) The purpose of this Regulation; To determine the procedures and principles regarding the distribution of heating and sanitary hot water expenses to users of independent sections in existing and new buildings with more than one independent section, central or regional heating system and sanitary hot water system.
ARTICLE 5 – (1) This Regulation applies to the distribution of the following expenses to users of independent sections provided with heat or sanitary hot water. a) Operating expenses of central heating systems, b) Expenses for the use of heat and sanitary hot water by independent departments.
(2) Spaces are equipped with measurement equipment to measure heating and sanitary hot water consumption. Users of independent sections are obliged to allow the works and transactions to be carried out for this purpose. Except for malfunctions and maintenance, independent section users cannot intervene in the measurement equipment.
(3) The building owner, building manager, building management board, energy manager, authorized measurement companies and regional heat distribution and sales companies measure the consumption of heat or sanitary hot water monthly or at certain periods and issue expense sharing documents for independent section users.
(5) In order to limit the energy consumed, thermostatic radiator valves in accordance with TS EN 215 are used in buildings where central heating systems are used.
(6) Space temperatures in independent sections heated by central systems are adjusted to be at least 15 ° C.
ARTICLE 7 – (1) The building owner or building manager or building management board ensures that heat and sanitary hot water expenses are distributed to independent section users in accordance with consumption measurements and Article 8.
(2) Heat expenses arising from common areas, system losses and operating expenses are shared among independent section users in proportion to the closed usage areas.
(3) If thermometers are used in consumption measurements; A thermometer is installed on each radiator group used in independent sections, and measurements are made from all thermometers to determine the consumption of independent sections.
(4) If a heat meter is used in consumption measurements; In independent sections, measurements are made from heat meters to find the consumption of independent sections.
(5) In case different measurement equipment is used in consumption measurements of building or site users; By first measuring all consumption, the shares of user groups whose consumption is measured with the same equipment are measured.
ARTICLE 11 – (1) If the heat or sanitary hot water shares of the independent sections cannot be determined due to an equipment malfunction or inability to measure accurately due to a similar reason in the period when the expense sharing certificate is issued, the shares shall be calculated according to the shares of the independent sections in question in the previous periods when similar expense sharing certificates were issued. It is determined by the building manager, building board of directors, energy manager, regional heat distribution and sales companies or authorized measurement companies, based on their consumption or the consumption of other similar independent sections in the period when the expense sharing certificate is issued.

Although there are many data acquisition systems depending on the features supported by the meters, more than 95% of the meters and share meters used as central system equipment are read either by wired communication system or wireless communication systems. In other words, users of independent sections are not disturbed to get counter values.
In the wired communication system, meters are connected to a main line with cables depending on a communication protocol called m-bus. Values can be taken from the central reading board by computer or automatically via the internet.
In wireless reading systems, meters and share meters can be read by walking around the building and its corridors using a handheld computer and reading antenna, and they can also be read automatically via the internet with data collectors installed between floors and gateway devices placed in the center.
The central heating system provides much more comfort and efficiency than the combi boiler system. If you live in a building with a combi boiler, your neighbors will turn off their combi boilers completely, causing you to consume much more heat energy.
However, according to the heat expense sharing legislation, space temperatures in a building with a central system must be adjusted to a minimum of 15 C. You will not experience heat loss.
On the other hand, since hot water is provided from a single boiler in the central system, higher savings are achieved throughout the building. The central system boiler is operated and maintained by a professional team. In this respect, it is also much safer than the combi boiler system.
Yes, it is legal. If it is technically detected that any violation has occurred in the expense sharing systems; It is considered that action can be taken regarding the amounts to be paid by users of independent sections who engage in manipulation, with the decision to be taken by the “Board of Flat Owners” within the scope of the Condominium Law No. 634 or with the “Decision of the Board of Directors” authorized by the Board of Flat Owners on the relevant issue.
According to the heat meter inspection regulations that came into force in 2018, it has become mandatory for heat meters to be inspected every year by inspection laboratories authorized by the Ministry of Industry.
The determining factor for the inspection period of the meters is the production year coded with M code on the meter. For example, if you see the M16 value on your meter or on its label, this meter will be sent for inspection by your site management in 2021.
If the authorized laboratory determines that the meter is within the measurement range specified in the legislation as a result of its inspection, it approves the meter; if it is not within the measurement tolerance range in the legislation, it does not approve the meter. It may be possible to calibrate this meter according to its brand and model. If it is not possible to calibrate, this meter must be replaced with a new meter. Otherwise, it is not legally possible to use it and a fine of over 2,500 Liras is imposed by the Ministry of Industry officials.
If you do not want to wait for a periodic examination, you can request a complaint examination according to this legislation. For this, you need to apply to the authorized laboratory of the Ministry of Industry. Or you can get the support of our company for such a request.
It is very simple to check if water meters are not measuring correctly. Although it may seem a somewhat primitive method, this control can be achieved with a demijohn of known volume, for example 19 liters. For this purpose, the value of the meter in liters is taken, it is filled into the carboy, and after filling, it is possible to check how many liters the meter has advanced.
