Abstract:
A green roof is a roof of a building that is covered
from a vegetation. Green roofs are beneficial in number of ways
for buildings. Crops in green roofs are exposed to direct solar
radiation and strong winds. Furthermore, the substrate is shallow
and it can hold limited amount of water. Therefore, artificial
irrigation methods are required especially for green roofs in tropical
countries. This paper proposes a novel irrigation controlling
method for green roof based on predicted evapotranspiration.
The system is capable of predicting the evapotranspiration and
deciding the amount of water to be irrigated based on that.
The rationale behind the proposed method is also explained.
Particulars on designing and developing a prototype irrigation
controller and a laboratory test bed for experimenting with green
roofs are presented. Experiments have been carried out and
the experimental results are discussed in order to analyze the
performance of the proposed system. The experimental results
validate the applicability of the proposed system.
