Green Roof Actual Evapotranspiration

Retention is water captured by the green roof that only leaves as vapor through the process of evapotranspiration.

Green roof actual evapotranspiration.

Anna zakrisson on sunday may 26 2019. They provide shade to the top of a building evapotranspiration. Most of the analysed studies performed a comparison between green roof evapotranspiration plants substrate and bare soil evaporation only substrate. Evapotranspiration rates determine green roof retention by dr.

When the subject of energy and green roofs comes up nearly everyone familiar with the topic will tell me that green roofs stay cool because of evapotranspiration. In the literature available however it is still not clear how and how much the evapotranspiration affects the performance of a green roof. In order to fill the gap in this research topic this study carries out a review on the cooling effect due to the evapotranspiration process of green roofs. Evapotranspiration why even when discussing it with professional engineers doing building energy modeling they assume that most of the cooling ability of a green roof is through.

Little research has been completed on evapotranspiration et in green roofs. Retention and evapotranspiration are always the same volumes. Evapotranspiration is the process of water escaping as vapor. The plants in a green roof absorb water through their roots and then use surrounding heat from the air to evaporate the water while some roofs can reach temperatures of up to 90 f in the summertime these two features can allow.
