The methodology consisted of characterization of the case study, survey data of water consumption and data of precipitation in the area, on-site visits to define the average consumption and monthly water distribution, and sizing of a rainwater harvesting tank following the Netuno Program. It was obtained 22.500 L as the ideal volume for the tank, supplying the demand for drinkingwater in 32%, although the reduction in the drinking water bills would be minor, since the object of the case study is considered SIH, and residents pay a fixed fee for consuming up to 10 m3 per month. Therefore, it becomes necessary to analyze this situation from a sustainable and environmental perspective, and the benefits are no longer only economic, but rather they take on a more comprehensive social dimension.展开更多

By implementing the design concept of classical Chinese garden in the whole process, this landscape design presented well-organized central green spaces, took fl owing water as the framework, arranged different activity spaces according to actual terrains, designed the bridge to connect both sides of the brook, placed garden settings and benches properly, combined plants properly, and make the whole residential district green and energetic. From the overall planning to the architectural unit design and central landscape design, the residential district shows the ancient rhythm of Chinese elements, and an ecological and harmonious overall environment. The unit design has practical plane, beautiful form, graceful and elegant style, it integrates well into the overall environment.展开更多
