居家日常熱水使用行為與設備改善之省水節能評估

近年來由於地球暖化以及溫室效應等議題，建築用水過程的耗能致使的排碳量開始受到重視，而減少耗水及節約用水被認為是減少用水及排碳量最重要的因素。熱水系統是給排水系統中最耗能的部分，可分為產熱端、傳輸端與使用端，而熱水使用空間則可分為浴室、盥洗空間與廚房洗手台。為達成建築熱水系統省水減碳之目的，本研究透過現況調查與熱水用水實驗(沐浴、洗髮、洗手、洗臉、洗碗)，掌握出水器具的省水機制(含用水量、水壓、出水形式)，以及用水行為將能有效探討合適的省水效益，進而提出改善行為設計與設備評估機制，達到居家省水改善與節能減碳之目的，並達到省能之附加價值。

Global warming is become a serious issue of the world in recent year. Water saving is considered to be the most important factor in reducing CO2 emission of water consumption in residential building. Hot water supply system consumes most energy in plumbing system and can be divided into heat generation part, the transmission part and the use part. This study analyze the using water devices characteristics (flow rate, pressure, ejection mode) and hot water using experiments (showering, hair rinsing, hand washing, face washing, dishwashing) to discussed about optimum water saving efficiency. Finally, submit the assessment of the energy consumption and CO2 emission reduction benefits for improved hot water supply system.
