CHAIR COMMUNAL HYGIENE AND HEALTH. L ECTURES ON ENVIRONMENTAL SANITATION 5 COURSE Hygienic bases PLANS RESIDENTIAL BUILDINGS LECTURER PROF. Iskandarova GT

Designing of residential buildings should be carried out in strict accordance with the climatic and socio-demographic features of the region Projects of houses as mass (typical) and individual housing should include such architectural and planning solutions that would ensure:

The lack of separation into the air space and in the atmosphere of harmful or strong-smelling substances and excessive heat input from both internal sources and external; The lack of an unpleasant blast, tangible difference in air temperatures both vertically and horizontally; The absence of elevated levels of heavy ions of both signs (positive and negative), bacterial contamination, humidity and temperature;

No or acceptable levels of noise, vibration, ultrasound, electromagnetic waves, radio frequency, static electricity; High quality sound insulation; Replace the heat capacity of building structures less heat capacity; Replacement of fixed shading devices on the window openings and the openings on the transformable summer premises;

The materials used and the design of shading devices on their thermal properties should approach the tree (with ionizing radiation equal to 5-7); Replacement of window openings without vents on window frames with transoms and vents; A complete set of built-in furniture, cabinets, mezzanines.

R EQUIREMENTS FOR PUBLIC PREMISES PUBLISHED IN RESIDENTIAL BUILDINGS The choice of sites for construction of residential buildings, as well as placing them in the houses provided under Chapter KMC-94 for construction of urban and rural settlements, and the requirements of these regulations. The territory is determined to build on non-agricultural land or unsuitable for agriculture It is strictly forbidden to construct buildings and communications..

R EQUIREMENTS FOR PUBLIC PREMISES PUBLISHED IN RESIDENTIAL BUILDINGS The residential buildings are not allowed public facilities, have harmful effects on human Facilities for public use, built-in residential buildings must have inputs, isolated from the living area.

Requirements to the internal layout of residential buildings In the design of residential buildings and construction type planning structure should be possible to respond to the specific climatic and social conditions, the demographic composition of the population, to take into account the duration of the adverse weather conditions.

P LANNING REQUIREMENTS RESIDENTIAL BUILDINGS Requirements to the internal layout of residential buildings In the design of residential buildings and construction type planning structure should be possible to respond to the specific climatic and social conditions, the demographic composition of the population, to take into account the duration of the adverse weather conditions.

REQUIREMENTS G ARBAGE D ISPOSAL Residential buildings must be equipped with garbage, arranged in accordance with the applicable building codes and regulations (other permitted waste disposal systems, subject to agreement with the authorities and institutions of the State Sanitary and Epidemiological Service).

R EQUIREMENTS FOR HVAC In residential buildings should include heating and exhaust ventilation with a natural impulse through the vents and air ducts. Exhaust channel openings must be provided in the kitchens, bathrooms, toilets and a drying cabinet. The unit of the ventilation system must exclude the flow of air from one apartment to another. Not allowed to join the ventilation ducts of kitchens and sanitary facilities with residential facilities.

Period of the year Air temperature, 0 С Relative humidity, % Mobility of air not exceeding m / s Warm ,2-0,25 cold ,1-0,15

W ATER SUPPLY AND SEWERAGE In residential buildings with centralized water supply should provide water supply with hot and cold water, fire hoses and sanitary sewer. In the absence of a centralized system of water supply, sewerage and heat and gas supply should focus on stand-alone systems engineering equipment (rural houses).

R EQUIREMENTS FOR NATURAL A RTIFICIAL LIGHTING AND INSOLATION In the design of natural and artificial lighting in residential and ancillary facilities should follow the requirements of sanitary norms and rules.

DIRECTION OF RESIDENTIAL BUILDINGS. Natural light and insolation separate functional premises of apartment houses and public buildings, their thermal comfort is largely dependent on the correct orientation and placing them in the territory of the village.

P ERMISSIBLE NOISE LEVELS Sanitary norms of permissible noise penetrating into the premises of residential and public buildings from internal and external sources, and acceptable noise levels in residential areas must be observed without fail in accordance with the "Sanitary norms of allowable noise in residential and public buildings and in residential areas."

REQUIREMENTS A RCHITECTURAL E NGINEERING Building materials used in the construction of residential buildings must meet the following stringent requirements: Has low thermal conductivity and provide sufficient thermal resistance and heat resistance barriers. Have good air permeability and porosity. Being a non-hygroscopic and has a low sound conductivity.

To ensure durability, fire resistance, durability ( years) facilities. Not released to the environment volatiles, creating odors and concentrations that may have a direct or indirect impact on human health. Do not encourage the development of microflora growth of fungi and algae.

Being accessible treatment and disinfection. Building materials used in housing, can be divided into two groups - natural and artificial. A special group of man-made building materials are synthetic polymeric materials (plastics).
