Abstract:
The replacement of permeable areas by buildings and constructions, because of urbanization, has
as result the increase of flooding and temperature in urban areas, which has led to excessive
energy expenditure. The use of green roofs has been one of the alternatives to minimize these
environmental problems. This study aimed to analyze the behavior of temperature on a green
roof covered with Zoysia japonica grass and conventional roof on a small scale. The temperature
of the green roof (GR), conventional aluminum roof (AR) and ambient was measured three times
a day for nine days. The green roof was connected to an irrigation system in order to maintain
the moisture content of the grass. In this system, it was added a known volume of water, and
with the final volume in the end of the experiment, it was possible to determine the
evapotranspiration rate of the GR. The results showed the thermal efficiency of the GR.
Therefore, the green roof is an alternative approach to improve the thermal comfort in buildings
promoting a reduction of temperatures and minimization of runoff flow |
