Research of Cooling Effect of Vegetation Layer of Green Structures in Construction

Abstract

Energy efficiency of construction can be improved by green structures combined with living plants. Cooling effect can decrease the refrigeration load on air conditioning or cooling systems. Nevertheless, there is no academic definition of it. We propose defining this effect as temperature drop by transpiration cooling because of evapotranspiration. The results of researches in wind tunnel provide the recommendation about boosting the air flow in refrigeration period, throttling it at spring and autumn if the grass is mowed or boosting the flow if the grass is not mowed but taking in mind problems with some opened corners.
