The Philippines is in a tropical location where rainwater is abundant for the frequent rain in a year. Rainwater becomes waste flowing down the drains causing flood, especially in urban areas. This problem initiates local governments in some cities in the Philippines to adapt and implement Green programs that require the installation and utilization of rainwater catchment system. Though this program addresses the control of flood caused by the rain, the generation of energy by utilizing rainwater as an energy source is not yet considered. With this, the study computes the equivalent energy generation by utilizing rainwater. The rainwater energy equivalent includes the following: the increasing number of high-rise building construction as catchment facility; the rainfall precipitation of 58 stations in the Philippines; the floor area and the types of the building; and the volume of water consumption per person per day. The energy equivalent was computed using the 40% of the time the rainfall precipitation equaled or exceeded the other with the average floor area specified from the approved building permit as of 2017. The study established a mathematical equation as an equivalent energy of rainwater utilization. The equation of energy equivalent was derived using the initial building height of 5 meters and an additional succeeding height of 3 meters per floor level.

“…The rainfall precipitation at 40% of the rainfall precipitation duration curve were considered computing the potential rainwater energy equivalent. The potential energy of rainwater precipitation collected from the existing buildings was computed by the equations ( 1) and ( 2) [5,14,15] as, PE = δgV ol HCr (1)…”

“…Gaur et al [21] and MacKay [22] reported their research on the performance of solar panels and informed that in locations with full sunlight, the benefits of solar panels are 10 W/m 2 ; where [21] more broadly examined several different solar cells. The use of solar panels in Indonesia has great potential because it is more efficient and more affordable by taking advantage of economic and environmental benefits, as studied by [23] who used solar panels to power water pumps for daily needs.…”

This study tries to verify how the integration of solar panels as a shading device can reduce indoor air temperature. Two stages of the experiment have been conducted, the first experiment compared the shadowing performance of the solar panels placed parallel in front of the window, while the second experiment compared the shadowing performance of the solar panels placed 45 degrees on the top edge of the window with the panels aligned in front of the window. Two models of similar buildings have been built; to see how much influence the location of solar panels as a shading device, the surface temperature of the glass and indoor air temperature were measured using temperature and humidity data loggers. The measurement results of the first experiment showed that compared to a model without solar panels, especially from 7 a.m. to 5 p.m., significantly decreased by an average of 2.5°C and 0.6°C consecutively to the glass surface temperatures and the indoor air temperatures. In the second experiment, the comparison of shadowing performance between solar panels placed parallel in front of the window with panels placed tilted 45 degrees indicates that especially for windows on the East side the use of solar panels placed parallel in front of the window is more potential. This result also has the potential to become a renewable energy source, but further research is still needed, especially regarding solar panel electricity production capacity.

“…The utilization of meteorological data in the analysis is beneficial since it can determine the incorporating factor of landslide (geology, morphology etc.,) instead of mere hydrological factor. In general, the rainfall analysis is not limited to the purpose of landslide only but it is also applicable for various application such as flood analysis and calculation of rainfall volume for the purpose of water harvesting as shown by the study carried out by Pudyastuti et al [7].…”
