过去几年，在空气污染监测应用 "Air Visual"的排行上，曼谷一直位居全球空气质量最差城市的榜首。根据数据显示，曼谷的PM2.5值在2020年12月曾经达到118微克/立方米。PM2.5在曼谷并不是最近才存在的危机，根据IQAir的数据，2020年，在曼谷由于空气污染造成的死亡人数估计为9500人，造成的经济损失达37亿美元。显然，这是一个需要迫切关注的严重问题。

In the last few years, Bangkok has topped the lists of cities with the worst air quality in the world on Air Visual, a famous air pollution monitoring app. According to the data, with the highest peak of 118 μg/m3 in December,2020. The Fine Particulate Matters (PM 2.5) crisis is not a new phenomenon. In 2020, according to IQAir, air pollution caused an estimate of 9,500 deaths in Bangkok and US$3.7 billion in damage. Obviously, this is a severe problem that needs urgent attention.

针对城市未来的发展，项目Elio Del Nest倡导以"过滤城市空气"概念为核心的研究型设计，将全新的现代生活与对环境和居民健康的高度关注融为一体。

In response to the city’s future development, Elio Del Nest promotes a research-based design centered on the concept of Urban Air-Filtration, that integrates a new modern living with great concern for the environment and residents’ health.

设计从住宅楼的布置开始，住宅楼分为7个单元，向上堆叠，模仿山体的轮廓，这样可以减少建筑占地面积，最大限度地利用室外绿地，使得绿地面积占总面积的比利大于67%。

Starting from the arrangement of residential buildings. The residential buildings are divided into seven units that stack upwards, mimicking the formation of mountains. The final scheme reduces building footprints and maximizes outdoor green spaces which is up to 67% of the total areas.

景观团队与专家紧密合作，旨在解决空气污染问题，主要目的是减少空气中的PM2.5、一氧化碳、二氧化碳以及挥发性有机物，以缓解空气污染。经过研究，团队在场地的适当位置提出了空气过滤策略，PM2.5吸收区位于入口广场，作为第一层收集细小颗粒的区域。团队也广泛研究了吸收PM2.5、碳、挥发性有机物以及释放氧气植物的能力和功能，并选择了适当的本地植物品种组合，以配合每个区域的空气过滤策略。

The landscape team worked closely with experts to tackle air pollution problems, approach that focuses on reducing the exposure of PM2.5, CO, CO2 and VOCs in order to alleviate air pollution. After the study, the air-filtration strategy was proposed at an appropriate location on the site. PM2.5 absorption zone is located at the entry plaza acting as the first layer of collecting fine particles. Carbon absorption zone aims to reduce Carbon from vehicle emissions along the corridor and parking lots. VOCs absorption zone is in the North West area of the site to reduce VOCs released from the nearby industries. we extensively examined plant capabilities and functions that absorb PM2.5, Carbon, VOCs and release O and chose groupings of local planting species appropriately to complement the purpose in each zone.

此外，我们还提出了效仿自然的“城市森林”概念，以构建自然环境，提高人类和城市生物的生活品质。在这片幸福的城市森林里，鸟儿和它们的栖息地将成为繁盛的象征。景观团队探索了将“鸟巢”作为概念的灵感来源，象征着庇护所、安全和自然的生育能力的鸟巢，启发了该项目的主要设计概念。

Moreover, we proposed a nature-mimicry concept of urban forest to construct a natural environment that enhances human and urban creatures' qualities of living. In the blissful urban forest, birds and their habitats would appear as an indication of abundance and exuberant bloom. The landscape team explored a bird nest as a muse for this concept. The nest's essential characteristics inspired the main design concept of this project to symbolize sanctuary, safety, and natural fertility.

设计的形式反映了自然界的运动状态，从而为软景和硬景空间带来平衡。绿化空间与各种户外活动相结合，分为三个层次，氧谷、绿道和峰林，层次交错，最大限度地提高了户外空间的利用率。“氧气股”一圈总长1.5千米，为在树冠下的环形跑道上慢跑或散步的人们提供了空间。

The design form reflects the dynamic movements of nature hence bringing balance to softscape and hardscape spaces. The green spaces integrated with various outdoor activities, dividing into three layers, The Oxygen Valley, The Green Hike and The Pinnacle Forest welcome the residents. The layers interlace maximizing the utilization of outdoor spaces. The Oxygen Valley offers them the choice to jog or walk on the loop underneath the green canopies and the green hike with 1.5Km. per round.

因应城市的未来发展，项目Elio Del Nest以对环境和居民健康的高度关注融入了全新的现代生活，它的目标是为小区、为区域、为城市，甚至为后代减轻空气污染。

In response to the city’s future development, Elio Del Nest integrates a new modern living with great concern for the environment and residents’ health. It targets to mitigate air pollution for the neighborhood’s areas, for the city and even for generations to come.
