Study on the cooling effect of black locust and linden trees in from Technical Univ. of Munich
Trees cool the environment; however, the degree of cooling depends greatly on the tree species and the local conditions. In a recent study, scientists at the Technical University of Munich (TUM) compared two species of urban trees – the black locust and linden.
The analysis by the research team becomes clearer by comparison: The output of a mechanical air conditioner is between one and ten kilowatts (kW) that of a linden tree up to 2.3 kW. This cooling capacity is fed by various processes such as their dense treetops that provide shade. Or the fact that the leaf surfaces reflect the short-wave rays of the sun and also use them for transpiration.
