4 new zones of light climate in Ukraine: Ternopil became the first
The updated State Building Standards (DBN) for natural and artificial lighting came into force on February 28, 2019. According to them, the territory of Ukraine is divided according to the light climate into 4 zones (previously there were 2). This zoning will allow more accurate calculations when designing buildings and calculating the minimum area of windows, which is necessary to improve insolation and increase the comfort of the premises. According to the current DBN, Ternopil region is included in the first light-climatic zone.
Now, to calculate the required level of natural light in the premises, for each region of Ukraine will use the appropriate light climate data. It has already been mentioned that so far Ukraine has been divided into only 2 zones. The first included Odessa region and the Autonomous Republic of Crimea, the second - other regions. This division was not very convenient. Therefore, the map of light-climatic zoning was significantly specified and expanded to 4 zones.
So, the new light-climatic zones now look like this:
- Zone I - regions: Ternopil, Khmelnytsky, Rivne, Lviv, Ivano-Frankivsk, Volyn, Zhytomyr;
- Zone II - oblasts: Kyiv, Cherkasy, Chernivtsi, Zakarpattia, Vinnytsia, Chernihiv, Sumy, Kharkiv, Poltava;
- Zone III - regions: Luhansk, Donetsk, Dnipropetrovsk, Kirovohrad;
- Zone IV - the Autonomous Republic of Crimea, regions: Kherson, Odessa, Mykolaiv, Zaporizhia.
The new State Building Standards as an alternative to those that have been in force since 2006. Their observance is obligatory when designing new and reconstruction of existing buildings, quarters, microdistricts according to their purpose.
DBN of February 28, 2019 apply to the design of lighting in residential, civil, industrial buildings and structures, in industrial and agricultural enterprises, outdoor lighting of settlements, including streets, roads, parks, beaches, building facades, adjacent areas, playgrounds, etc.
