Requirements to Choice of Site for CPI

· Accessibility for population - radius of service in microdistrict is 300 m;

· Optimal hygienic conditions on the site (optimal microclimate, absence of air pollution by chemical and physical factors, presence of green plantations).

Requirements to Site of CPI

· The site area is 30-40 m2 per child;

· There should be 2 entrances – the main and economic; the form of the site should be rectangular;

· There should be special functional zones on the site based on principle of group and age isolation: zone of building; zone of group playgrounds; zone of sports grounds; economic zone; zone of green plantations.

Requirements to Functional Zones on CPI Site

Zone of Building up

Systems of CPI building up may be:

· Centralized (it is not optimal from the hygienic point of view as all groups and economic premises are in one building);

· A pavilion type of building up (it requires a lot of place, the construction is expensive);

· Block building up (modern projects include blocks of, for example, day nursery, kindergarten, gymnasium, economic block).

The building should be located not closer than 25 m from the site border, be surrounded with green plantations (trees - not closer than 10 m, bushes – 5 m from the building to preserve the normal natural light exposure).

Zone of Group Playgrounds

The area of group playgrounds should be 7.2 m2 per child, a shadow canopy - 40 m2, game and sports equipment should correspond to age. Calculation of the necessary number of playgrounds should be made proceeding from one playground per two day nursery groups or four kindergarten groups. The playgrounds are separated by a zone of green plantations.

Zone of Sports Grounds

Zone of Green Plantations

It should occupy not less than 50 % of the site area. Plants with prickles producing irritating and allergenic action, poisonous wild-growing plants should be excluded.

Requirements to Layout of CPI

The major principle of layout is the principle of group isolation which provides:

· prevention of infectious diseases;

· possibility to carry out quarantine measures;

Microclimate: the air temperature is 21-22ºC (in a day nursery) or 18-20ºC (in a kindergarten), air humidity - 40-60 %, speed of air movement – 0.1-0.3 m/sec.

Ventilation: frequency rate is 3, volume of ventilation per child is 20 m3/h, CO2 content - up to 0.1 %.

Illumination: natural - LC 1/4-1/5, CNI – 1.5 %, light angle on desks - 27º, corner of aperture – 5º. Artificial common illumination - 150 lux.

Premises for general use: gymnasium and music hall (75 m2 each), methodical room; additional premises: a swimming pool, hall, study for hand work and drawing.
