Spatial Data on Cooling-related Economic Benefits from Urban Allotment Gardens in Wrocław, Poland (2014-2024)

This dataset contains geospatial and tabular data used to quantify the cooling effect of urban allotment gardens on adjacent buildings and the resulting reduction in cooling energy demand and costs in Wrocław, Poland.
The dataset is provided in an ESRI File Geodatabase (GDB) format within a ZIP archive and includes four primary layers/classes:
ALLOTMENTS: Polygon layer of aggregated allotment garden complexes, with a unique COOLED_ZONES_ID.
COOLED_ZONES: Polygon layer of the spatial extent of cooling influence for each allotment complex, with COOLED_ZONES_ID.
BUILDING_FOOTPRINTS: Polygon layer of cooled building footprints within the study area, with BUILDING_OBJECTID.
BUILDINGS_DATA: Attribute table containing the results of microclimatic and energy calculations for the "cooled" buildings. Key fields include various TAIR (air temperature) metrics, CDD (Cooling Degree Days), and CDEM (cooling demand). Values suffixed with _m2 are per square meter and must be multiplied by the building's usable floor area (UFA), considering the SATURATION_PERCENTAGE (air-conditioning penetration rate) for accurate aggregation.

The data enables the replication of the core methodology: delineating cooled zones, calculating building-specific CDD reductions, and estimating subsequent energy and cost savings attributable to allotment gardens.

本数据集包含地理空间与表格数据，用于量化波兰弗罗茨瓦夫市城市自留菜园（allotment gardens）对邻近建筑的降温效应，以及由此引发的制冷能耗需求与成本削减幅度。
本数据集以ZIP压缩包内的ESRI文件地理数据库（File Geodatabase，GDB）格式提供，包含四个核心图层/要素类：
ALLOTMENTS：连片城市自留菜园综合体的面状图层，各要素带有唯一标识符COOLED_ZONES_ID；
COOLED_ZONES：各菜园综合体降温影响空间范围的面状图层，带有COOLED_ZONES_ID字段；
BUILDING_FOOTPRINTS：研究区域内受降温影响的建筑基底面状图层，带有BUILDING_OBJECTID字段；
BUILDINGS_DATA：存储“受降温影响”建筑微气候与能耗计算结果的属性表。核心字段包含各类TAIR（气温，air temperature）指标、CDD（降温度日数，Cooling Degree Days）以及CDEM（制冷需求，cooling demand）。后缀为_m2的数值为每平方米统计值，若需实现精准聚合，需结合SATURATION_PERCENTAGE（空调渗透率，air-conditioning penetration rate），将该数值乘以建筑可使用楼面面积（UFA，usable floor area）。
本数据集可支撑核心研究方法的复现：划定降温影响范围、计算单栋建筑的CDD削减量，并估算由城市自留菜园带来的后续能耗与成本节约额度。
