Boiler installations protecting atmosphere against emission of pollution
This API provides access to subject P4064 of Poland's Local Data Bank (Bank Danych Lokalnych, BDL), maintained by Statistics Poland (GUS). It covers data on boiler installations designed to protect the atmosphere from pollutant emissions, part of the broader Housing Economy and Municipal Infrastructure category, specifically heating system management. The dataset consists of yearly territorial time series available at multiple administrative levels, from voivodship down to gmina (municipality), with each unit identified by its TERYT territorial code. It supports statistical analysis of heating infrastructure and environmental protection measures across Polish regions and localities.HOUSING ECONOMY AND MUNICIPAL INFRASTRUCTURE › HEATING SYSTEM MANAGEMENT. Local Data Bank (BDL) subject P4064: yearly territorial series for Poland (voivodship to gmina level), units keyed by TERYT ids.

| Field | Type | Description |
|---|---|---|
| variable_idVariable id | string | GUS variable id identifying the measured series: exhauster facilities or low-emission burners.GUS variable id selecting the measured series of subject P4064 (the n1/n2 dimension combination): 1622075=exhauster facilities [pcs]; 1622076=low-emission burners [pcs]. |
| unit_levelUnit level | integer | Territorial aggregation level from country (0) down to gmina (6).Territorial aggregation level: 0=Poland, 1=macroregion, 2=voivodship (województwo), 3=region, 4=subregion, 5=powiat, 6=gmina. |
| year | integer | Reference year of the yearly data value.Reference year of the value (yearly series, back to 1995 for the oldest subjects). Filters server-side via the API's year parameter. |
| unit_idUnit id | string | 12-digit BDL territorial unit identifier combining regional codes.12-digit BDL territorial-unit id (macroregion+voivodship+region+subregion+powiat+gmina+type digits). An equality filter pins the unit server-side (unit-parent-id). |
| unit_nameUnit name | string | Name of the territorial unit, e.g. country, region, or gmina.Name of the territorial unit, e.g. country, region, or gmina. |
| teryt_tercTeryt terc | string | TERYT TERC administrative code for the territorial unit.TERYT TERC territorial code derived from the unit id (2 digits = voivodship, 4 = powiat, 7 = gmina incl. type digit; empty for NUTS-only units). |
| value | number | Numeric value of the measured variable for the unit and year.Numeric value of the measured variable for the unit and year. |
