Suitability of roofs for the use of solar energy
Solar energy that reaches the earth’s surface can be utilised with the aid of the two established solar technologies, photovoltaics (electricity) and solar thermal energy, for the product...
Suitability of façades for the use of solar energy
The sun's energy that reaches the Earth's surface can be used, via two proven forms of solar technology – photovoltaics (electric current) and solar thermal energy (heat) – to generate re...
Catchments in karst regions
The Karst catchments layer depicts those areas where seepage water flows into a specific spring and feeds it. Catchments can occasionally overlap, namely where sections of them drain towa...
Catchment units in karst regions
The Karst catchment units layer consists of the unit areas from which similar groundwater flow behaviour towards the karst spring can be expected. In particular, it allows for the phenome...
