平實公園開發理念有三，一為對生態的尊重，再為減廢再利
The philosophy behind the park development project highlights regard for the

Regard for the eco-system means reducing damage caused by development.
生；尊重當地人文歷史即是尊重當地地貌的紋理，不以大規模 「重置（Reset）」開發之觀念破壞基地內所有記憶，以此低 衝擊開發設計概念作為規劃設計之重要準則。 公園設計階段時以前述理念及規劃構想，將原有道路改窄，
Waste reduction and recycling means cutting down on energy consumption and carbon footprint. Care for local culture and history means respecting the texture of the local landscape without destroying the memories of the base by resetting the development settings on a large scale. The “Low Impact Development” concepts are the guidelines for the design of the park.

Ponds receiving water from flood control grass slopes have a permeable base that can store large amounts of water from torrential rains, lighten the workload of the drainage system, and add to the park’s soil moisture content. After the successful development of the park, plants and trees at the base have been noticeably growing better. Trees used to lose leaves early and their bark was usually covered with moss and lichen. Such conditions are

The benefits that this project brings to the environment include conserving water in an area of 66,000 square meters, keeping the amount of carbon emissions at 263,000 kilograms through preserving 90 percent of old trees in the park, reducing 31,640 kilograms of carbon emissions through an extensive use of LED lights, storing 7,500 cubic meters of water from floods, and recycling 41,060 kilograms of construction waste. They are the praise-worthy achievements of this project.
