本研究採用回顧過往便利商店節能對策之研究，並邀請產官學界代表共同集思廣義，完成可透過簡易評估方式，進行便利商店能源分級認證制度。本分級認證制度根據便利商店節能成效與達成評估項目的難易程度進行設計，分為三大建築型態（室內型、治街型、獨棟型）、六大評估類別（冷凍冷藏、空調冷氣、照明燈具、建築空間、電力管理、使用管理）及四十二項節能評估項目，依照建築型態與認證分數的高低給予一至三級的認證等級。本分級認證已於2011年開始執行，已完成2,005家便利商店之分級評估，對於提升業者與國家節能成效上將有重要貢獻。

This research reviewed related studies of strategies on energy-saving in convenience stores firstly, and then invited experts from industry, government and academia to establish the first convenience stores energy grading and certification system. According to energy-saving performance and the difficulties in execution, this system was divided into three building construction types (indoor, along the street, detached ) , 6 categories of assessment (freezing and refrigeration, air conditioning, lighting, building space, power management, use and management), and 42 energy assessment. Every convenience store was estimated by building type and scores and then given one to three certification levels. This system has assessed 2,005 convenience stores since 2011, and it has great contribution to enhancing the effects of the industry and the national energy conservation.
