1. 響應高雄市政府推動綠屋頂之政策，並結合本校醫療藥學專業，延續中醫藥學對於藥食同源的養身理念，進而於本案部分場域，打造健康藥草蔬食園，於設計構想中，納入環保再生建材、隔熱蓄排水工法及多功能活動空間之設計理念，打造出一座增加校園綠地、減少碳足跡、節能減碳，並兼具教學研究、園藝療癒及供社區民眾及師生交誼休憩之多功能活動空間。
2. 綠化新增40種植栽，並含藥用及食用植栽，另設置有蔬菜箱，可依季節及實際需求種植短期性蔬菜，透過本案屋頂種植各種植物，增加城市生態系統的多樣性，另可提供蝴蝶、蜜蜂、瓢蟲、蚯蚓及麻雀、黑冠麻鷺、鴿、夜鷺…等各種生物棲息繁衍，促進生態交流；對聯合國永續發展目標SDGs13完備減緩調適行動，以因應氣候變遷及其影響和城市生態環境的保護，具有積極且正面的作用。
3. 使用工法及材質皆為輕量化考量，採用隔熱蓄排水板及輕質配方土之薄層綠化工法，減少建築荷重；蔬菜箱與地板間之架空層，能阻擋陽光照射，降低樓板溫度，達到節能減碳效益。另設置自動澆灌系統，定時定量，避免水資源浪費，亦不增加管理者之負擔。
4. 屋頂綠化可藉由隔熱蓄排水板之空氣斷熱，可阻擋陽光熱源，並利用植被有效折抵太陽輻射，減少熱島效應，從而降低建築物表面的溫度。因此，在屋頂種植完成後，表面被植被覆蓋，實際測量圖書館大樓屋頂表面的溫度較施工前下降2~5%，大約減少冷暖氣耗電量20%，有效達成節省能源效益和減少溫室氣體排放之效益。
5. 本案的設置除增加校園綠地外，更提供學校舉辦活動和文化藝術展覽及校內教職員工休憩場域，並開放社區民眾及樂齡學員交誼使用，藉由自然環境和園藝活動，師生能夠與大自然互動，有助於改善身心健康。此外，還可以增加社區參與度，提高環保意識，促進社區發展和共融。

Project Title: Garden of Luxury, Rooftop of The library of Kaohsiung Medical University
Project completion year: 2017
Project Location: Kaohsiung City, Taiwan
Project Type: Retrofit Green Roof
Green Roof Type: Extensive & Intensive
Total vegetated roof area: 634M²
Project feature:

1. This project responds to Kaohsiung City Government's policy promoting green roofs and combines the expertise of the school's pharmacy professionals to continue the traditional Chinese medicine philosophy of "food and medicine sharing the same origin" by creating a healthy herb and vegetable garden. The design incorporates concepts of environmental-friendly recycled building materials, insulation, storage and drainage systems, and multi-functional activity spaces to create a green space on campus, reduce carbon footprint, and provide a versatile space for teaching, research, horticultural therapy, and community activities.
2. There are 40 plants in this rooftop greening including medicinal and edible plants. There are also many vegetable boxes placed to provide seasonal vegetables by growing short-term vegetables according to the season and actual needs. After one year, the diversity was observed due to the variety of habitats and plants. And the biodiversity is consistent until today when the butterflies, bees, ladybugs, earthworms, sparrows, black-crowned sparrows, pigeons, night herons, etc., were observed. This Garden not only provided a great urban ecosystem but also achieved the goal of SDGs13 to cope with climate change.
3. The project uses lightweight materials and insulation systems, such as insulated drainage boards and lightweight substrates, to reduce building weight and solar radiation. An automatic irrigation system is also installed to conserve water and reduce the burden of maintenance.
4. This roof greening could block the heat of sunlight through the insulation drainage board. The vegetation offsets the solar radiation and reduces the heat island effect effectively, thereby reducing the temperature of the building surface. Therefore, the temperature on the rooftop surface of this library building is 2-5% lower than that before construction, which reduces the electrical power consumption of cooling and heating by about 20%
5. This project not only increases green space on campus but also provides space for school events, cultural and artistic exhibitions, and staff rest areas. It is open to the community and the seniors for social interaction and horticultural activities, which can improve physical and mental health, and promote environmental awareness, and community development.
