本研究室以永續發展目標(Sustainable Development Goals, SDGs) 研究為旨，契合2050淨零排放之全球趨勢。台灣政府也訂定2025年再生能源占比20%之目標，並以再生能源和零碳能源系統作為能源轉型計劃，佈建太陽光電與離岸風能並導入氫能。城市風能作為潛在新興能源，雖然尚未被具體納入綠能科技產業創新推動方案，但相信未來仍有最大化城市再生能源之發展潛力，實現可負擔的潔淨能源目標(SDG 7)。在聯合國設立的17項永續發展目標中，強調以人為本的核心價值，後續發展主題也因應而生，如：採取氣候行動(SDG13)減緩氣候變遷、應用數位孿生技術打造淨零排放之永續城市與社區(SDG 11)、確保城市環境中綠地和公共空間人們在城市中感受之舒適度、確保室內外通風透氣下擁有良好空氣品質與健康福祉之生活環境(SDG 3)、實現淨零循環建築設計以達到深度節能促進工業化創新基礎建設(SDG 9)。

在發展綠能和節能的條件下，能源轉型產業涵蓋範圍廣泛，對於創新整合和實踐技能之跨域人才需求非常迫切。本研究室期許系統性地培育跨領域之淨零碳排專業人才(SDG 4)，以女性角度多元觀點發展永續綠能與產學接軌並就業實現STEM領域性別平權(SDG5)，將相關知能投入永續發展之推廣與研究中，建立跨領域合作多元夥伴關係(SDG 17)、強化國際鏈結、實現產業升級，並迎接淨零轉型所帶來之高度挑戰。
