"NATURAL AND ARTIFICIAL LIGHTING. SNiP 23-05-95" (approved by the Decree of the Ministry of Construction of the Russian Federation of 02.08.95 N 18-78)

BUILDING REGULATIONS Introduction

SNiP 23-05-95 was developed in accordance with common system regulatory documents in construction and is part of complex 23 (Appendix B of SNiP 10-01-94).

The document establishes the norms for natural, artificial and combined lighting of buildings and structures, as well as the norms for artificial lighting of residential areas, enterprise sites and places of work outside buildings.

1 area of ​​use

These standards apply (with the exception of cases specified in other chapters of the SNiP) to the design of lighting for the premises of newly built and reconstructed buildings and structures for various purposes, places of work outside buildings, sites of industrial and agricultural enterprises, railways of enterprise sites, outdoor lighting of cities, towns and rural settlements. The design of local lighting devices supplied complete with machines, machines and industrial furniture should also be carried out in accordance with these standards.

These standards do not apply to the design of lighting for underground workings, sea and river ports, airfields, railway stations and their tracks, sports facilities, medical institutions, premises for storing agricultural products, placement of plants, animals, birds, as well as for the design of a special technological and security lighting when using technical means of protection.

On the basis of these standards, industry lighting standards are developed, taking into account the specific features of the technological process and construction solutions for buildings and structures of the industry, which are agreed and approved in in due course.

2. Regulatory references

These rules and regulations refer to the following documents:

SNiP 2.01.01-82 "Construction climatology and geophysics".

SNiP 2.05.09-90 "Tram and trolleybus lines".

SNiP 2.07.01-89* "Urban planning. Planning and development of urban and rural settlements".

3. Definitions

In these rules and regulations, terms are used in accordance with Appendix A.

4. General provisions

4.1 The normalized values ​​of illumination in these standards are given at the points of its minimum value on the working surface inside the premises for discharge light sources, except for specified cases; for outdoor lighting - for any light sources.

The normalized values ​​of the brightness of road surfaces in these standards are given for any light source.

Normalized values ​​of illumination in lux, differing by one step, should be taken on a scale: 0.2; 0.3; 0.5; 1; 2; 3; 4; 5; 6; 7; 10; 15; 20; thirty; 50; 75; 100; 150; 200; 300; 400; 500; 600; 750; 1000; 1250; 1500; 2000; 2500; 3000; 3500; 4000; 4500; 5000.

4.2 Requirements for room lighting industrial enterprises(KEO, normalized illumination, permissible combinations of glare indicators and pulsation coefficient of illumination) should be taken according to Table 1, taking into account the requirements of clauses 7.5 and 7.6.

The requirements for lighting the premises of residential, public and administrative buildings (KEO, rated illumination, cylindrical illumination, discomfort index and illumination pulsation coefficient) should be taken according to Table 2.

4.3 The safety factor Kz when designing natural, artificial and combined lighting should be taken according to Table 3.

4.4 Artificial and combined lighting should be designed taking into account the requirements for ultraviolet irradiation in accordance with current sanitary standards and guidelines"Prophylactic ultraviolet irradiation of people (using artificial sources of ultraviolet radiation)".

5. Natural light

5.1 Premises with permanent residence of people should, as a rule, have natural lighting.

Without natural lighting, it is allowed to design premises that are defined by the relevant chapters of SNiP for the design of buildings and structures, normative documents By building design buildings and structures of certain industries, approved in the prescribed manner, as well as premises, the placement of which is allowed in the basement and basement floors buildings and structures.

5.2 Natural lighting is divided into side, top and combined (top and side).

In small rooms with one-sided lateral natural lighting, the minimum KEO value is normalized at a point located at the intersection of the vertical plane of the characteristic section of the room and the conditional working surface at a distance of 1 m from the wall farthest from the light openings, and with two-sided side lighting - at a point in the middle of the room . In large industrial premises with side lighting, the minimum KEO value is normalized at a point remote from light openings:

1.5 heights of the room for works of I-IV categories;

"2" ""V-VII"

"3" ""VIII"

In case of upper or combined natural lighting, the average KEO value is normalized at points located at the intersection of the vertical plane of the characteristic section of the room and the conditional working surface (or floor). The first and last points are taken at a distance of 1 m from the surface of the walls (partitions) or the axes of the columns.

It is allowed to divide the room into zones with side lighting (zones adjacent to external walls with windows) and zones with overhead lighting, normalization and calculation of natural lighting in each zone are made independently of each other.

In industrial premises with visual work of I-III categories, combined lighting should be arranged. It is allowed to use overhead natural lighting in large-span assembly shops, in which work is carried out in a significant part of the volume of the room at different levels from the floor and on work surfaces differently oriented in space. In this case, the normalized values ​​of KEO are accepted for ranks I-III, respectively, 10, 7, 5%.

5.3 Normalized values ​​of KEO, eN, for buildings located in different areas (Appendix D) should be determined by the formula

eN = eH mN, (1)

where N is the number of the natural light supply group according to Table 4;

eH - the value of KEO according to tables 1 and 2;

mN - light climate coefficient according to Table 4.

The values ​​obtained by formula (1) should be rounded to tenths.

Notes:

1 For the sub-category of norms from Ia to IIIc, one of the sets of normalized indicators given for this sub-category in columns 7-11 can be taken.

2 Illumination should be taken taking into account paragraphs 7.5 and 7.6 of these standards.

3 The smallest dimensions of the object of distinction and the corresponding categories of visual work are established when the objects of distinction are located at a distance of no more than 0.5 m from the eyes of the worker. With an increase in this distance, the category of visual work should be set in accordance with Appendix B. For extended objects of distinction, the equivalent size is selected according to Appendix C.

4 Illumination when using incandescent lamps should be reduced according to the illumination scale (clause 4.1 of these standards):

a) one step with a combined lighting system, if the rated illumination is 750 lux or more;

b) the same, general lighting for categories I-V, VI;

c) in two steps with a general lighting system for categories VI and VIII.

5 Illumination when working with luminous objects with a size of 0.5 mm or less should be selected in accordance with the size of the object of distinction and referred to the subcategory "c".

6 The glare indicator is regulated in column 10 only for general lighting (with any lighting system).

7 The pulsation coefficient Kp is specified in column 10 for a general lighting system or for local lighting fixtures with a combined lighting system. Kp from general lighting in the combined system should not exceed 20%.

8 It is allowed to provide a general lighting system for categories I-III, IVa, IVb, IVc, Va only if it is technically impossible or economically inexpedient to use a combined lighting system, which is specified in industry lighting standards agreed with the State Committee for Sanitary and Epidemiological Surveillance of the Russian Federation.

9 In areas with the temperature of the coldest five-day period according to SNiP 2.01.01 minus 27 ° C and below, the normalized KEO values ​​\u200b\u200bwith combined lighting should be taken according to Table 5.

10 In premises specially designed for work or industrial training of adolescents, the normalized value of KEO is increased by one category according to group 3 and must be at least 1.0%.

On the basis of these standards, industry standards for lighting are developed, taking into account the specific features of the technological process and construction solutions of buildings and structures of the industry, which are agreed and approved in the prescribed manner.

References to the following documents are used in these rules and regulations:
SNiP 2.01.01-82 "Construction climatology and geophysics".
SNiP 2.05.09-90 "Tram and trolleybus lines".
SNiP 2.07.01-89* "Urban planning. Planning and development of urban and rural settlements".

3 DEFINITIONS

In these rules and regulations, terms are used in accordance with Appendix A.

4 GENERAL

4.1 The normalized values ​​of illumination in these standards are given at the points of its minimum value on the working surface inside the premises for discharge light sources, except for specified cases; for outdoor lighting - for any light sources.

The normalized values ​​of the brightness of road surfaces in these standards are given for any light source.

Normalized illumination values ​​in lux, differing by one step, should be taken on a scale: 0.2: 0.3; 0.5; 1; 2; 3; 4; 5; 6; 7; 10; 15; 20; thirty; 50; 75; 100; 150; 200; 300; 400; 500; 600; 750; 1000; 1250; 1500; 2000; 2500; 3000; 3500; 4000; 4500; 5000.

4.2 Requirements for lighting the premises of industrial enterprises (KEO, rated illumination, permissible combinations of glare and pulsation coefficient of illumination) should be taken from Table. 1 subject to the requirements of paragraphs. 7.5 and 7.6.

Requirements for lighting residential premises. public and administrative buildings (KEO, rated illumination, cylindrical illumination, discomfort index and illumination pulsation coefficient) should be taken according to Table. 2.

4.3 The safety factor Kz when designing natural, artificial and combined lighting should be taken from Table. 3.

4.4 Artificial and combined lighting should be designed taking into account the requirements for ultraviolet irradiation in accordance with the current sanitary standards and guidelines "Prophylactic ultraviolet exposure of people (using artificial sources of ultraviolet radiation)".

5 NATURAL LIGHTING

5.1 Premises with permanent residence of people should, as a rule, have natural lighting.

Without natural lighting, it is allowed to design premises that are determined by the relevant chapters of SNiP for the design of buildings and structures. regulatory documents for the construction design of buildings and structures of individual industries, approved in the prescribed manner, as well as premises, the placement of which is allowed in the basement and basement floors of buildings and structures.

5.2 Natural lighting is divided into side, top and combined (top and side).

In small rooms with one-sided lateral natural lighting, the minimum KEO value is normalized at a point located at the intersection of the vertical plane of the characteristic section of the room and the conditional working surface at a distance of 1 m from the wall farthest from the light openings, and with two-sided side lighting - at the point in the middle of the room -schenie. In large industrial premises with side lighting, the minimum KEO value is normalized at a point remote from light openings:

1.5 heights of the room for works of I-IV categories;

"	2	"	"	"	V-VII	"
"	3	"	"	"	VIII	"

In case of upper or combined natural lighting, the average KEO value is normalized at points located at the intersection of the vertical plane of the characteristic section of the room and the conditional working surface (or floor). The first and last points are taken at a distance of 1 m from the surface of the walls (partitions) or the axes of the columns.

It is allowed to divide the room into zones with side lighting (zones adjacent to external walls with windows) and zones with overhead lighting, normalization and calculation of natural lighting in each zone are made independently of each other.

In industrial premises with visual work of I-III categories, combined lighting should be arranged. It is allowed to use upper natural hanging in large-span assembly shops, in which work is carried out in a significant part of the volume of the room at different levels from the floor and on work surfaces differently oriented in space. In this case, the normalized values ​​of KEO are accepted for categories I-III, respectively, 10, 7, 5%.

5.3 Normalized values ​​of KEO, e N , for buildings located in different areas (Appendix D) should be determined by the formula

e N = e H m N (1)

where N is the number of the natural light supply group according to Table. 4;
e H - the value of KEO according to the table. 1 and 2;
m N - coefficient of light climate according to table. 4.

The values ​​obtained by formula (1) should be rounded to tenths.

ON THE APPROVAL OF SP 52.13330 "SNIP 23-05-95*

NATURAL AND ARTIFICIAL LIGHTING"

In accordance with the Rules for the development, approval, publication, amendment and cancellation of sets of rules approved by Decree of the Government of the Russian Federation of July 1, 2016 N 624, subparagraph 5.2.9 of paragraph 5 of the Regulations on the Ministry of Construction and Housing and Communal Services of the Russian Federation, approved by the Decree Government of the Russian Federation dated November 18, 2013 N 1038, paragraph 42 of the Plan for the development and approval of codes of practice and updating previously approved codes of rules, building codes and regulations for 2015 and the planning period until 2017, approved by order of the Ministry of Construction and Housing Public Utilities of the Russian Federation dated June 30, 2015 N 470 / pr, as amended by order of the Ministry of Construction and Housing and Communal Services of the Russian Federation dated September 14, 2015 659 / pr, I order:

1. Approve and put into effect 6 months from the date of publication of this order SP 52.13330 "SNiP 23-05-95 * Natural and artificial lighting" in accordance with the appendix (not given).

2. Since the entry into force of SP 52.13330 "SNiP 23-05-95 * Natural and artificial lighting" recognize as not applicable SP 52.13330.2011 "SNiP 23-05-95 * Natural and artificial lighting", approved by order of the Ministry of Regional Development of the Russian Federation of December 27, 2010 N 783, with the exception of paragraphs of SP 52.13330.2011 "SNiP 23-05-95 * Natural and artificial lighting", included in the List of national standards and codes of practice (parts of such standards and codes of practice), as a result the application of which on a mandatory basis ensures compliance with the requirements federal law"Technical Regulations on the Safety of Buildings and Structures", approved by Decree of the Government of the Russian Federation of December 26, 2014 N 1521 (hereinafter referred to as the List), before the relevant changes are made to the List.

(see text in previous edition)

3. The Department of Urban Development and Architecture, within 15 days from the date of issue of the order, send the approved SP 52.13330 "SNiP 23-05-95 * Natural and artificial lighting" for registration to the national body of the Russian Federation for standardization.

4. The Department of Urban Development and Architecture shall ensure the publication on the official website of the Ministry of Construction of Russia in the information and telecommunication network "Internet" of the text of the approved SP 52.13330 "SNiP 23-05-95 * Natural and artificial lighting" in electronic digital form within 10 days from the day registration of the set of rules by the national body of the Russian Federation for standardization.

Natural and artificial lighting in the premises is regulated by the norms of SNiP 23-05-95, depending on the nature of visual work, the system and type of lighting, the background, the contrast of the object with the background. The characteristic of visual work is determined by the smallest size of the object of distinction (for example, when working with instruments - the thickness of the scale graduation line, when drawing work - the thickness of the thinnest line). Depending on the size of the object of distinction, all types of work related to visual tension are divided into eight categories, which, in turn, depending on the background and the contrast of the object with the background, are divided into four sub-categories.

Artificial lighting is normalized by quantitative (minimum illumination Emin) and qualitative indicators (blindness and discomfort indicators, illuminance pulsation coefficient kE).

Separate rationing of artificial lighting has been adopted depending on the light sources used and the lighting system. The normative value of illumination for gas-discharge lamps, other things being equal, due to their greater light output, is higher than for incandescent lamps. With combined lighting, the share of general lighting should be at least 10% of the rated illumination. This value must be at least 150 lux for gas discharge lamps and 50 lux for incandescent lamps.

To limit the glare of general lighting fixtures in industrial premises, the glare index should not exceed 20 ... 80 units, depending on the duration and category of visual work. When lighting industrial premises with gas-discharge lamps powered by alternating current of an industrial frequency of 50 Hz, the pulsation depth should not exceed 10 ... 20%, depending on the nature of the work performed.

When determining the norm of illumination, one should also take into account a number of conditions that necessitate an increase in the level of illumination selected according to the characteristics of visual work. An increase in illumination should be provided, for example, with an increased risk of injury or when performing intense visual work of I ... IV categories throughout the working day. In some cases, it is necessary to reduce the illumination rate, for example, when people stay indoors for a short time.

Natural lighting is characterized by the fact that the created illumination varies depending on the time of day, year, meteorological conditions. Therefore, as a criterion for assessing natural lighting, a relative value is taken - the coefficient of natural illumination of the KEO, which does not depend on the above parameters.

KEO is the ratio of the illumination at a given point inside the room Evn to the simultaneous value of the external horizontal illumination En, created by the light of a completely open sky, expressed as a percentage, i.e.

KEO = 100 Eur/En.

Separate rationing of KEO was adopted for side and top natural lighting. With side lighting, the minimum value of KEO is normalized within the working area, which must be provided at points furthest from the window; in rooms with overhead and combined lighting - according to the average KEO within the working area. The normalized value of KEO, taking into account the characteristics of visual work, the lighting system, the location of buildings in the country:

en = KEO ts,

where KEO - coefficient of natural illumination; determined according to SNiP 23-05-95;

m - coefficient of light climate, determined depending on the location of the building in the country;

c is the coefficient of sunshine of the climate, determined depending on the orientation of the building relative to the cardinal points;

coefficients m and c are determined according to the tables of SNiP 23-05-95.1

Combined lighting is allowed for industrial premises in which visual work of I and II categories is performed; for industrial premises under construction in the northern climatic zone of the country; for rooms in which, according to the conditions of technology, it is required to maintain stable parameters of the air environment (areas of precision metalworking machines, electroprecision equipment). At the same time, general artificial lighting of the premises should be provided by gas-discharge lamps, and the illumination standards should be increased by one step.
