隨著工商業的快速發展及人民生活水平不斷提高，使得各國能源需求量大增，目前全球的能源供應，主要來自石油、煤炭等石化燃料，有鑑於自然資源的耗損，綠色能源的技術開發已成為國家發展與學術研究的重要議題。都市建築物日常用水在使用後即被排放，如何利用日常用水的能量轉換成電力，是本研究之探討重點。
本研究改良已開發用於河川之微水力發電技術(Micro-hydroelectricity Power Technology)概念，將其微小化並應用於建築物給水管中，藉由建築物給水管中水流產生的流速，牽引超微型水力水輪機轉換水力為機械能，此機械能再經過永磁式同步發電機轉換為電能。超微水力系統在使用上無需面對高電壓或高功率等衍發之具損壞特性過程，擁有較長的使用年限且可減少維修成本。本研究應用空氣動力學的創新微型葉片設計，讓葉片面對水流向之截面積極小化，其葉片優點體積小、重量輕、成本低且擁有靈活的結構設計。本研究預計透過實驗電量監測、蓄電效益、分析集合住宅用電型態、個人(或家庭)用水量調查，探討超微水力發電技術在建築物之應用可行性評估及未來可應用之領域。

With the rapid development of industries, commerce, and standards of living, the energy requirements of various nations are significantly increasing. Currently, the primary sources of global energy supply are oil, coal, and other fossil fuels. Because of the depletion of natural resources, the development of green energy technology has become a vital topic in national development and academic research. Considering that the household water in urban buildings is discarded after use, converting the energy from household water into electricity is the focus of this study.

In this study, the micro-hydroelectric power technology developed for applications in rivers will be modified and minimized for applications in the water supply pipes in buildings. The flow produced in building water supply pipes will be used to drive Pico -hydroelectricity turbines and convert hydroelectric power into mechanical power. This mechanical power will then be converted into electric power through permanent-magnet synchronous generators. Pico-hydroelectric systems do not involve the damaging procedures of high currents or high power use, and have a long service life that reduces maintenance costs. In this study, innovative micro blades with aerodynamic design will be used to minimize the cross-sectional area of water flow. In addition to the flexible structural design, these blades are advantageous because they are small, lightweight, and inexpensive. To explore the feasibility of using Pico -hydroelectric power technology in buildings, experimental power and storage efficiency will be monitored, residential power use patterns collected and analyzed, and individual (or family) water use surveyed.
