10.3 Elements, parts, equipment with service lives shorter than the expected service life of the building must be replaced in accordance with the between-repair periods established in the project and taking into account the requirements of the design assignment. The decision to use less or more durable elements, materials or equipment with a corresponding increase or decrease in overhaul periods is established by technical and economic calculations.

At the same time, materials, designs and technology construction work should be selected to ensure minimal subsequent repair, maintenance and operating costs.

10.4 Structures and parts must be made of materials that are resistant to possible exposure to moisture, low temperatures, aggressive environments, biological and other adverse factors in accordance with SNiP 2.03.11.

If necessary, appropriate measures must be taken to prevent the penetration of rain, melt, and groundwater into the thickness of the load-bearing and enclosing structures of the building, as well as the formation of an unacceptable amount of condensation moisture in the external enclosing structures by sufficiently sealing the structures or installing ventilation of enclosed spaces and air spaces. The necessary protective compounds and coatings must be used in accordance with the requirements of current regulations.

Equipment and pipelines must be secured to the building’s building structures in such a way that their functionality is not affected by possible movements of the structures.

10.7 When constructing buildings in areas with difficult geological conditions, subject to seismic influences, underworking, subsidence and other soil movements, including frost heaving, utility service entries must be made taking into account the need to compensate for possible foundation deformations in accordance with the requirements established in regulatory documents for various engineering networks.

11 ENERGY SAVING

11.1 The building must be designed and constructed in such a way that, while meeting the established requirements for the internal microclimate of the premises and other living conditions, the efficient and economical use of energy resources during its operation is ensured.

11.2 Compliance with the requirements of energy saving standards is assessed by the thermal characteristics of building envelopes and engineering systems or by a complex indicator of the specific consumption of thermal energy for heating and ventilation of the building.

11.3 When assessing the energy efficiency of a building based on the thermal characteristics of its building structures and engineering systems, the requirements of these standards are considered met under the following conditions:

1) the reduced resistance to heat transfer and air permeability of enclosing structures is not lower than those required by SNiP 23-02;

2) heating, ventilation, air conditioning and hot water supply systems have automatic or manual control;

3) the building's engineering systems are equipped with metering devices for thermal energy, cold and hot water, electricity and gas with a centralized supply.

11.4 When assessing the energy efficiency of a building based on a comprehensive indicator of specific energy consumption for its heating and ventilation, the requirements of these standards are considered to be met if the calculated value of specific energy consumption to maintain standardized microclimate and air quality parameters in the building does not exceed the maximum permissible standard value. In this case, the third condition 11.3 must be met.

11.5 In order to achieve optimal technical and economic characteristics of the building and further reduce specific energy consumption for heating, it is recommended to provide:

The most compact space-planning solution for the building;

The orientation of the building and its premises in relation to the cardinal points, taking into account the prevailing directions of cold wind and solar radiation flows;

Application of efficient engineering equipment of the corresponding range with increased efficiency;

Utilization of heat from exhaust air and wastewater, use of renewable energy sources (solar, wind, etc.).

If, as a result of the above measures, conditions 11.4 are provided with lower values of heat transfer resistance of enclosing structures than required by SNiP 23-02, then the heat transfer resistance of walls can be reduced compared to the established standards.

The thermal characteristics of the building and the energy efficiency class are included in the energy passport of the building and subsequently clarified based on the results of operation and taking into account energy saving measures.

11.6 In order to control the energy efficiency of a building according to standard indicators, the design documentation must contain a section “Energy Efficiency”. This section should contain the energy passport of the building in accordance with SNiP 23-02, information on the assignment of the energy efficiency class of the building, a conclusion on the compliance of the building design with the requirements of these standards and recommendations for increasing energy efficiency if it is necessary to finalize the project.

6 LOAD-LOADING CAPACITY AND DEFORMATIVITY OF STRUCTURES

6.1 The foundations and load-bearing structures of the building must be designed and constructed in such a way that during its construction and in the design operating conditions the possibility is excluded:

destruction or damage to structures leading to the need to cease operation of the building;

unacceptable deterioration in the operational properties of structures or the building as a whole due to deformations or the formation of cracks.

6.2 The structures and foundations of the building must be designed to withstand constant loads from the own weight of load-bearing and enclosing structures; temporary uniformly distributed and concentrated loads on floors; snow and wind loads for a given construction area. Standard values of the listed loads, taken into account unfavorable combinations of loads or corresponding forces, maximum values of deflections and displacements of structures, as well as values of safety factors for loads must be adopted in accordance with the requirements.

The additional requirements of the customer-developer specified in the design assignment must also be taken into account, for example, for the placement of fireplaces, heavy equipment for public premises built into a residential building; for fastening heavy elements of interior equipment to walls and ceilings.

6.6 If, during reconstruction, additional loads and impacts occur on the remaining part of the residential building, its load-bearing and enclosing structures, as well as the foundation soils, must be tested for these loads and impacts in accordance with current standards, regardless of the physical wear of the structures.

In this case, it is necessary to take into account the actual bearing capacity of the foundation soils as a result of their changes during operation, as well as the increase over time in the strength of concrete in concrete and reinforced concrete structures.

6.7 When reconstructing a residential building, changes in its structural design that arose during the operation of this building should be taken into account (including the appearance of new openings additional to the original design solution, as well as the impact of repairs to structures or their strengthening).

6.8 When reconstructing residential buildings with a change in the location of sanitary facilities, appropriate additional measures should be taken for hydro, noise and vibration insulation, as well as, if necessary, strengthening the floors on which the equipment of these sanitary facilities will be installed.
