The map shows the buildings´ locations and their climatic conditions according to the classification system of KOEPPEN.
This system uses letter codes to identify the major climate zones: (A) tropical forest, (B) dry forest, (C) warm temperate rainy, (D) cold forest, and (E) polar regions. Further subdivision according to the temperature, rainfall, and seasonal variations is described through sub-codes:
- BSk: Mid-latitude steppe. Semiarid, cool or cold.
- Csa: Interior Mediterranean. Mild winter and dry hot summer.
- Csb: Coastal Mediterranean. Mild winter and dry, short, warm summer.
- Cfa: Humid subtropical. Mild winter and moist in all seasons.
- Cfb: Marine. Mild winter and moist all seasons. Warm summer.
- Cfc: Marine. Mild winter and moist all seasons. Short cool summer.
- Dfb: Humid continental. Severe winter, moist all seasons with a short warm summer.
- Dfc: Subarctic. Severe winter, moist all seasons with a short, cool summer.
- ET: Tundra. Very short summer.
Another climate classification according to energy consumption of buildings (ASHRAE) is described in the glossary.
