有電就有電磁波，高科技產物為現代人類帶來便利的同時，伴隨而來電磁波隨時隨地存在建築空間各個角落。我國為順意世界潮流，已建置電磁波相關管制規範。世界衛生組織(WHO)認為目前無法斷定電磁波對民眾影響之主要因素知識的不足。本研究以兩家連鎖式咖啡廳內外空間為研究對象，進行電磁波調查、分析與比較，藉以瞭解電磁波與各項影響因子之關聯性。
本研究彙整國內外相關理論、研究成果及電磁波管制規範，作為後續分析基礎，再經由專家訪談之手法，避免錯誤及加強研究之精確度及效率。其次向地政部門申請調查標的之現況測量圖，再至現場補充調查底圖，並以行政院環境保護署公告之環境中極低頻與射頻電場與磁場檢測方法為測量基準，再參考專業調查業者及管理單位意見，建置量測點。本研究以平均格狀式佈點，量測高度距地面一公尺。調查儀器採用可同時量測極低頻及射頻電磁波之量測儀器，實驗過程中直接將量測數據登記於調查底圖中。
研究發現，調查對象之極低頻及射頻電磁波皆符合國內規範；休閒空間之天花板高度與極低頻強度有相關；廚房、櫃台等特殊用途空間之設備及裝修尺度與極低頻電磁波有相關；室內上網密度與極低頻、射頻電磁波強度無明確關聯性，室外射頻電磁波會透過玻璃外牆進入室內，影響程度大於室內無線上網，一般而言室內射頻電磁波強度小於室外。再者藉由問卷調查結果得知，一般民眾對電磁波相關知識仍不足。
Where there is electricity, there is electromagnetic wave. As the high-tech products bring convenience for modern people, they simultaneously bring electromagnetic wave and it exists in every corner of buildings and spaces anytime and anywhere. To comply with the global trend, the regulations are established to control electromagnetic wave. World Health Organization (WHO) considers that currently the main factor of the effect electromagnetic wave has on human beings cannot be defined as insufficiency of knowledge. The objects of the research are internal and external spaces of two franchise coffee shops, realizing the relations among electromagnetic wave and other affecting factors via investigating electromagnetic wave, analyzing, and comparing.
The research integrates domestic and international related theories, research findings, and electromagnetic wave regulations as the basis of follow-up analysis, and use expert interview method to avoid mistake and improve the accuracy and efficiency of the research. Then, apply to the land division for the current condition map of researching object, and then supplement the base map at the scene, establishing measurement point with the measuring reference of measurement of environmental extremely low frequency (ELF) electric fields, radio field and magnetic field published by Environmental Protection Administration of Executive Yuan and referring the suggestions of professional investigators and managing units. The measured altitude of the research is one meter above ground with average grid distribution, recording the measurement data on the research base map with measuring instrument which can simultaneously measure ELF and radio frequency electromagnetic wave during the experiment.
The research indicates that the ELF and radio frequency electromagnetic wave of the two objects compliance with the domestic regulations. Height of the ceiling in leisure space is related to the intensity of ELF; renovation dimension of spaces for special purpose like kitchen and counter is related to ELF electromagnetic wave; density of surfing the internet indoor has no clear relation with ELF and radio frequency electromagnetic wave. Generally, intensity of indoor radio frequency electromagnetic wave is weaker than outdoors because outdoor radio frequency electromagnetic wave can enter indoors through the glass walls and the impact is stronger than indoor wireless internet. The result of questionnaire survey shows electromagnetic wave related knowledge of the general public is insufficient.
