Small-leaved limes do not transpire to the same extent in all environments as a study by Mohammad Rahman from the Technical University of Munich (TUM) concludes. During the summer heat, transpiration - the loss of water from the leaves - from those trees grown in open green squares cools us down more effectively than grown in narrow, paved squares. This is caused by local differences in the meteorology and the surface covers.
Street canyons, roads, and squares get particularly hot in summer. Trees cool the asphalt under their crowns by up to 20 °C and the air by up to two degrees Celsius as demonstrated by studies conducted by Mohammad Rahman from the Chair for Strategic Landscape Planning and Management of TUM. ...
