Abstract (EN):
This research evaluates which is the most cost-efficient rainwater harvesting (RWH)
system in a new commercial building located in the north of Portugal, in Braga. Based on the
economic analysis, the cost-efficiency of the presented RWH strategies may be considered for
the case studied.
The results of this research indicate that RWH scenarios proposed are cost-efficient.
Considering a 10 % discount rate, the water price charge in the municipally of Braga and
the cost of the infrastructures would be enough to make RWH cost-efficient for this option. At
this discount rate, the payback period ranges from 2 to 6 years and the internal rate of return
would range from 23 to 76 %. If a discount rate of 5 % were considered, the payback periods
would be reduced by approximately 1 year.
