“…This figure was established by Osma Pinto [9] The thermal behavior of PV panels can be described by equations (1)-(4). The cell operative temperature given by (1) causes variation in the electrical parameters as maximum power current (I m ) and maximum power voltage (V m ), given by (2) and (3), respectively. The maximum point power (P m ) is given by (4).…”

This paper presents a study on the effect of the height installation of PV panels in a green roof integrated photovoltaic system (GRIPV) considering warm and humid climate conditions. According to recent work, there is mutual benefit between these two applications in temperate conditions. However, it is necessary to study this interaction in tropical conditions and to establish the significance of height as a factor of installation. Therefore, an experiment was designed using three PV panels of 250 W in portrait configuration with 10° of inclination; each PV panel uses a micro-inverter. The monitoring system can gather data such as ambient temperature, PV panel temperatures, solar radiation and electrical variables. The green roof used (440 m 2 ) is located on the Electrical Engineering Building of Universidad Industrial de Santander (Colombia), where the latitude is +7.1° and the ambient temperature varies between 24°C and 30°C during daily sun-time (6 am and 6 pm), while the relative humidity fluctuates between 60% and 90%. The experiment considers two height installations (50 cm and 75 cm) for both types of roof -black and green -for three weeks. According to the results, the lower height installation and the green roof increases the power output by 2.0% and 1.0%, respectively and the combined effect is nearly 2.8%.

“…Constructing green roofs combined with rainwater harvesting systems in buildings can boost the advantages of each of these technologies [28,29]; their combination should also be considered a very promising solution to face climate change and increase sustainability in cities [30,31]. When designing a rainwater harvesting system combined with a green roof structure, several factors should be considered, such as the roof runoff coefficient [32].…”

In addition to the possible contributions of buildings to mitigating CO 2 emissions, increased attention is being paid to the potential impacts of climate change on urban environments. According to the United Nations, about 54% of the planet's population currently lives in cities, but this percentage is expected to rise to 66% in 2050, which reveals the scale of this issue. This paper develops a reflection on the possible contributions of water-related building installations to mitigate emissions and increase urban area adaptation to the effects of climate change. One of the most promising solutions to facing climate change, which is analysed in detail in this paper, is combining rainwater harvesting systems with green roofs. However, in view of developing the necessary engineering projects, there are insufficient existing studies to estimate the parameters to be used in each location given their climate characteristics, particularly the monthly runoff coefficients, which constitute the key parameter for designing these installations in some regions. Some recent standards present generic theoretical values for designing these combined installations, but they are far from reality in some regions, such as the Mediterranean basin. Therefore, based on the data available in Portugal, this paper reports some of the results obtained from research on the values of the monthly runoff coefficients.

“…Green roofs allow traditional vegetation without disrupting urban infrastructures in any way. It is more useful when compared to alternatives, for it takes up negligible space (Sheng, Mari, Ariffin, & Hussein, 2011). There are two main types of green roofs: intensive and extensive.…”

This study is on monitoring program for urban Stormwater Management Manual for Malaysia (MSMA) and Eco-Hydrological in Kuala Lumpur, Malaysia. The rainwater was harvested and evaluated on the basis of three major parameters; Electric Conductivity, Dissolved Oxygen, pH, and indoor temperature. These parameters has been analyzed and compared with the National Water Quality Standards and Water Quality Index provided by the Department of Environment of Malaysia. This paper also analyzed the effect of using vegetated roofs on the pH value of rainwater using the adaptive neuro-fuzzy methodology, which simulates the rainwater quality parameter with adaptive neuro-fuzzy inference system (ANFIS). The performance of proposed system is consolidated by simulation results. The study revealed that the ANFIS model can be used to determine rainwater quality parameter with high reliability. For that reason, it can be connected for reasonable purposes. Meanwhile, the influence of green roof in reducing indoor temperature is very important.
