In late 2025, Korean state broadcaster, KBS, visited Taipei on a green building fact-finding trip as part of a special program about Busan being selected as World Design Capital for 2028. During their visit, they chose to visit Hung Kuo Building as an existing office building that has been transformed into an exemplar of green building performance.

世界綠建築協會選擇了宏國大樓成功的永續發展故事作為「2025世界綠建築週」的研究案例，並製作了一段短影片，呈現宏國大樓在綠建築改造的旅程中，所達成的多項ESG 成果，作為「世界綠建築週」活動的一部分。

In recognition of its historic achievement in becoming the first LEED v5 certified building in Taiwan, the US Green Building Council is highlighting Hung Kuo Building as an exemplary case study on its global website to help inform and inspire other projects preparing to certify with the latest, most stringent version of the world’s most popular green building rating system.
