While the practice of rainwater harvesting (RWH) can be traced back millennia, the degree of its modern implementation varies greatly across the world, often with systems that do not maximize potential benefits. With a global focus, the pertinent practical, theoretical and social aspects of RWH are reviewed in order to ascertain the state of the art.(More)
The main objective of this work is to develop a method for sizing window area based on the consumption of electricity in commercial buildings, when integration of daylight and artificial light with hybrid ventilation is considered. The method allows the estimation of the potential for electricity savings and the evaluation of the daylighting performance.(More)
The objective of this paper is to perform a sensitivity analysis of design variables and an uncertainty analysis of daily potable water demand to evaluate the performance of rainwater harvesting systems in residential buildings. Eight cities in Brazil with different rainfall patterns were analysed. A numeric experiment was performed by means of computer(More)
The aim of this study is to develop a method to assess window area based on electricity consumption in office buildings in southern Brazil. The method may be used in the preliminary building design process in order to help choose an adequate window area to minimize its impact on energy consumption, depending on climate, building size, solar orientation, and(More)
The objective of this study is to assess the environmental benefit of using rainwater, greywater, water-efficient appliances and their combinations in low-income houses. The study was conducted surveying twenty households located in southern Brazil, which resulted in water end-uses estimation. Then, embodied energy, potential for potable water savings and(More)
The main objective of this article is to assess the possibility of using short-term instead of long-term rainfall time series to evaluate the potential for potable water savings by using rainwater in houses. The analysis was performed considering rainfall data from 1960 to 1995 for the city of Santa Bárbara do Oeste, located in the state of São Paulo,(More)
The objective of this paper is to estimate the potential for electricity savings with the use of daylighting integrated with the artificial lighting system and hybrid ventilation in commercial buildings located in Florianópolis, southern Brazil. Several models were analysed. Two cases were investigated: a reference case, operating only with air-conditioning(More)
The main objective of this article is to present the calibration process of a computer model of a naturally-ventilated house built in southern Brazil. The house was monitored over two seven-day periods by using Hobo data loggers. The EnergyPlus computer program was used to create a computer model for the house; parameters related to air infiltration and(More)
