Regulations on heat insulation in buildings
| From the Ministry of Public Works and Settlement: REGULATIONS ON HEAT INSULATION IN BUILDINGS PART ONE Objective, Scope and Basis Objective and Scope ARTICLE 1 - These regulations have been prepared to reduce heat loss in buildings, achieve energy saving and define application guidelines. These regulations are applied in buildings in all settlements, including municipalities within scope of the Law No. 3030 on the Amendment and Enactment of the Statutory Decree on Administration of Metropolitan Municipalities. These regulation provisions cannot be applied in buildings such as warehouses, armories, stables, animal pens and similar buildings which are constructed separately and do not require heating. Public institutions and organizations, annexed budget administrations, provincial special administrations and municipalities which are within scope of Article 32 of the Statutory Decree No. 180 on the Organizations and Duties of the Ministry of Public Works and Settlement that is amended by Statutory Decree No. 209 are liable for complying with and applying these regulations. Basis ARTICLE 2 - These regulations have been prepared on basis of Article 2/n of the Statutory Decree No. 180 on the Organizations and Duties of the Ministry of Public Works and Settlement that is amended by Statutory Decree No. 209. PART TWO General Project Design Guidelines Temperature Zones ARTICLE 3 - Our homeland has been divided into four temperature zones in regard to heat insulation applications in buildings and the cities and districts in these zones are shown in the list in ANNEX 1-A and the four groups on the map in ANNEX 1-B. The municipalities that are not on the list will consider the values for the districts they are affiliated with. In the buildings that will be built in zone one, the limit values given for zone two will be valid in the heat insulation projects to be applied in such buildings if a central air conditioning system is to be implemented. Yearly Heating Energy Requirement ARTICLE 4 - Buildings will be insulated at levels that are in accordance with the environmental conditions and requirements in regard to heat loss. The calculated yearly heating energy requirements of buildings should not exceed the yearly heating energy limit values given in Table 1 according to zones. Thermal Conductivity Value and Thermal Conductivity Resistance ARTICLE 5 - The thermal conductivity calculation values and internal and external surface thermal conductivity resistance values for the various construction materials and components to be used in calculations will be taken from TS 825 while the thermal transmittance resistance values of air strata and the thermal transmittance coefficients of windows and external doors will be taken from TS 2164. The Thermal Transmittance of Flooring ARTICLE 6 - In new buildings where heat insulation calculations are made, the Ut value to be taken for flooring in heated areas can be chosen to be 25% lower than the Ut value recommended in the standard at most. Project Obligation ARTICLE 7 - In accordance with the provisions of these regulations and as per the calculation method specified in the TS 825 standard, the “heat insulation project to be prepared by the authorized mechanical engineer is demanded by the relevant authorities together with the installation project at the stage of acquisition of the building license as per the relevant regulations. Special Circumstances ARTICLE 8 - In regard to new and existing buildings of up to 2 floors and with a total surface area of less than 100m2 (excluding balconies, terraces, stairs and passages outdoors) outside of municipality borders and adjacent areas, located in the village settlements and hamlets of those registered at village populations and residing permanently at villages: The “Heat Insulation Project” specified in article 7 will not be mandatory if the thermal transmittance coefficients of construction elements are equal to or lower than the construction element U values specified in Table 2, the total window area is equal to or lower than 12% of the heat-losing external wall area, and the constructions and details that ensure these are shown in the architectural project and specified in the “Machinery Installation Report”. In such a case, a “Heat Insulation Project” that shows that the conditions above are met will be enough. However, if any " U " value is greater than the values given in (Table 2), a thermal insulation project for these buildings should be prepared. In case of thermal insulation in the existing buildings within municipal boundaries and adjacent areas, the insulation project of the building should be prepared by using the calculation method stated in TS 825. Documents Required for a Project ARTICLE 9 - The following information should be present in the heat insulation project. Heat losses, heat gains, gain/loss ratio, gain use factor and the amounts of the monthly and annual heat energy requirements should be provided in the form of graphs that are similar to the examples in the “Original Heat Loss of the Building” and “Annual Heat Energy Requirement” graphs; it should also be shown that the calculated annual heat energy requirement (Q) is is not higher than the limit value to be acquired from the annual heat energy requirement (Qı) formula in Table 1. In calculations that will be made in buildings used for purposes other than residence, if the temperature difference between the different sections of the building are over 4 K and an annual heat energy requirement is to be calculated for more than one section in the building, the borders of the sections should be drawn schematically and the temperature values of these should be shown. The materials used in the exterior walls, ceilings and floors/flooring of the building`s heat-loss surfaces, the arrangement and thickness of these materials in the element, the areas and the " U " values of the wall, ceiling and floor/flooring elements and should be specified. The type of window and frame used in window systems, the separate window areas for all directions, and the " U " values and the number of air changes (nh) required for the frame system should be specified. The type of ventilation must be specified. In the heat insulation project, the condensation which may occur on the heat-loss surfaces of the building should be verified as specified in TS 825-ANNEX 6. All reinforced concrete elements (columns, beams, girders and curtain walls, etc.) located on the outer surfaces must be absolutely insulated. Infilled walls shall be insulated if necessary according to the results of calculations. Repairs, amendments and joints shall be subject to the provisions of this regulation in whole or in independent parts of the building. While calculating the heating energy requirement (Q) of the buildings to be constructed in areas of adjacent arrangement projects (house rows, twin houses) the adjoined wall sections are also considered and taken into account as external walls. In other matters not specified in this regulation TS 825 will be complied with. Heat Insulation Principle Details ARTICLE 10 - Heat insulation principle details are given in Annex: 2/1-24. Details are given in order to guide the preparation of the Heat Insulation Project. Details will be made certain according to the material thicknesses that will be found at the end of the calculations. The basic principle in detail is to prevent the formation of heat bridges. Precautions should be taken for this. New materials to be included in the standards according to technological developments can also be used in details. Architectural Application Project ARTICLE 11 - The architectural application project and system details should be in accordance with the details of the materials and points in the thermal insulation project and should include details of roof-wall, wall-window and floor / floor-wall composition to provide continuity in thermal insulation. Heat Requirement Identification Certificate ARTICLE 12 - The "heat requirement identification certificate" given in (Table 3) must be included in the building manager`s file after being filled and signed by the authorized thermal insulation projector and the machine engineers performing the application and after approval by the municipality or the governorate. A copy should be hung at the entrance of the building. PART THREE Principles of Application in Buildings with Central Heating Boiler Rooms and Flues ARTICLE 13 - The following points shall be observed in the construction of boiler rooms and flues. A- Boiler Rooms Boiler rooms must be sized according to fuel type. The boiler rooms should be arranged as to have two doors that swing inwards and outwards. Boiler room doors should be made of non-combustible material. The boiler room door should not be opened directly to the stairwell. In order to prevent smoke from entering the building in case of leakage and fire, a small entrance room should be built and the doors of this room should be sealed and a threshold should be placed at the bottom. The front and back of the boilers and the right and left sides should have openings to allow any kind of maintenance, repair and intervention. The necessary ventilation must be provided in the boiler room in order to provide the fresh air necessary for the fuel type and to eliminate the exhaust air. An areaway should be made for this process to be completed healthily. With this application, it will be possible to make channels for gas-fired devices. If the wall of the boiler room is the outer wall or if the heat center has a separate building, the windows should be placed on the outer walls to be 1/12 of the boiler room floor area. Ensure that the fresh air inlet port is at the level of the floor outlet of the dirty air port is at the ceiling level. On the condition that the section of the fresh air suction port is not less than 50% of the smoke flue section in a facility with solid and liquid fuel, the exhaust ports section should be 300 cm2 until 50 kW (43000 kcal/h) and about 25% of the smoke flue section at the value, found by addition of 2.5 cm2 for every KW. In the case of gas-fired boilers, fresh air intake vent, smoke pit and exhaust pit sections should be determined according to the procedure and calculation values of gas companies and related gas distribution companies. In cases where natural ventilation is not possible in boiler rooms, induced ventilation should be applied. In this case: a- In liquid fuel, this ventilation capacity should be 0.5 m³ / h for every kW of the boiler. b- In liquid fueled boiler rooms with induced ventilation; Ventilator capacity = (burner fan capacity + aspirator capacity) must be x 1.1 and the fan must be operated at the same time as the burner. c- Solid fuels must have natural ventilation. d- In gas-fired boiler rooms, these choices shall be made according to the criteria of gas companies and gas distribution companies. This type of system is not applicable since there will be negative pressure in the boiler rooms with semi-induced ventilation, which are only with suction or exhaust. 10. If there are different fuel boilers in the boiler room, the highest value of flue and ventilation criteria should be taken as basis. 11. In cold areas and boiler rooms which are not used frequently, the ventilation shutters should have equipment that close them automatically. 12. The height of the boiler room should be calculated according to TS 2192. 13. Boiler users should be trained and certified according to the type of fuel used. 14. In the case of the use of liquid and gaseous fuels, the boiler houses may be installed in the roof provided as long as the necessary precautions are taken. In this case: a- In case of static calculations, the effect of the boiler room should be taken into consideration. (Approximately 1000-2000 kg / m²) b- Sufficient acoustic insulation should be applied in order to avoid undesirable effects to the places under the roof and areas beside it. Bases with vibration insulation should me made under boilers. c- Proper stairs should be made for exiting the boiler room. The doors and windows should be unlocked and arranged so that they can be opened easily in the escape direction. d- Fuel pipeline should be arranged to be close to a vertical installation channel or stairwell with natural ventilation that can be intervened with easily. e-Ventilation and other criteria should be the same as basement boiler rooms. B- Flues: A separate flue will be made for each boiler in accordance with its standard. However, in gas-fired boiler flues, the common flue can be applied according to the criteria recommended by gas companies or gas distribution companies. Boiler flues cannot be connected to flues of other devices such as water heaters, combi boilers, room heaters and generators. If possible, flues should be in the building. In case of necessity, if the boiler is built outside the building, the heat insulation and external protection necessary for cooling should be done. Flues with solid and liquid fuels should be made of solid bricks (filled with plaster) or fire bricks while boilers with gas fuels should be made of materials resistant to condensation effects with suitable production techniques. Precautions must be taken to ensure that the combustion noise is not transmitted in metal flues and the flues must be grounded. There should be a cleaning hatch at the bottom of the flues. In gas-fired boilers, a drainage arrangement must be made in addition to the cleaning hatch. Flues must be installed in such a way that they will not be affected by buildings and obstacles beside them, they must be at least 1 m high from the top point of such obstructions or the roof ridge in individual buildings; there should be flue caps on top. The chimneys should be made as vertical as possible, and in case of necessity, only one deviation should be permitted with a minimum angle of 60° at the horizontal. Smoke ducts must be made from and insulated with steel material. Stainless steel should be preferred in gas-fired boilers. The ducts should be arranged so that they can be easily cleaned, and measurement holes should be left for gas analysis. The horizontal length of the smoke ducts should not be more than 1/4 of the vertical volume, the channel should be connected directly to the main body with a rising inclination of 5%, there should be no more deviation from the two 45 ° angles and the 90 ° angle should never be used. Insulation materials in accordance with TS 901 must be used in the flue and smoke ducts. Precautions have to be taken in the flues of high buildings, for expansion and for the self-supporting of the flue. The flue section must be circular unless otherwise is mandatory. Radiators ARTICLE 14 - Reflection panels or film covered insulation panels should be placed behind the radiators mounted on the outer walls. Automated Control ARTICLE 15 - For energy saving, boilers with liquid and gas fuels should be preferred to be used with automatic control systems. According to the principles determined by gas companies and related gas distribution companies, a gas leakage control system should be established. PART FOUR Miscellaneous Provisions Conformity of Building and Insulation Materials to the Standards ARTICLE 16 - Thermal conductivity calculation values (lh) of construction and insulation materials are given in TS 825. TSE brand and Turkish Standard Certificate of Conformity should be documented in the building and insulation materials to be used in building construction with a report to be obtained from the laboratories accredited by TSE or TSE when it is necessary to comply with the value of lh thermal conductivity calculated for the materials to be used. However, if the calculated values of the thermal conductivities to be taken from the said institutions are lower than the values in TS 825 ANNEX-5, the lh values in TS 825 ANNEX-5 shall be used in the calculations. Heat Insulation Inspection ARTICLE 17 - The inspections on heat insulation at every stage of construction are carried out by municipalities within municipal borders and adjacent areas, and governor’s offices in settlements outside of these boundaries. The technical supervisor responsible for the control of the thermal insulation of the building reports to the municipality or the governor’s office by checking the insulation applied to the floor/slab, wall and ceiling phases of the building, after checking compliance of these with the details given in the project. Annulment Article 18 - With the coming into force of these regulations, the Regulations on amendment of the Building Bylaws of Certain Municipalities and Addition of New Articles to Such Bylaws which were published on Official Gazette No. 18637 of 16/1/1985 have been annulled. Provisional Article 1 - The provisions of these regulations shall not be applied in the public buildings of which construction work tender is declared before 14/6/2000 and in the private buildings where the construction license is obtained. Effectiveness Article 19 - This regulation will become effective on 14/6/2000. Enforcement Article 20 - The provisions in these regulations will be enforced by the Ministry of Public Works and Settlement. |
