Rainwater Harvesting is a water conservation practice with a long history of implementation. With the advent of public water supply systems, they have become less common in developed areas of the world but there has been a resurgence as people struggle to find ways to minimize our ever-increasing impact on our environment. One of the most important consideration in rainwater harvesting systems is the sizing of the tank that stores water for later consumption. With increasing tank size, more rainwater can be stored reducing the need for potable water in dual piping systems and reduced emissions from potable water, but with increasing tank size there is more tank material and greater emissions for tank material. The purpose of this study is to determine if there are existing building configuration where attempting to minimize the Global Warming Potential emissions (Maximize Sustainability method) from the system will result in lower emissions than sizing the system by maximizing system reliability (Max VR method). Simulations were conducted with @risk using both sizing approaches for five different building types a small, medium, and large office, an apartment and a house. The results demonstrate that all building scenarios show a reduction in CO2 emissions with the Maximize Sustainability method compared to BAU except for the house case. The Maximize Sustainability method produced lower CO2 emissions in all cases compared to the Maximize VR method confirming that sizing with the Maximize Sustainability method does result in improved emissions for the different building configurations.
