The Common Air-rea – Re-envisioning Public Space in the Age of Air Pollution – 目前，曼谷和世界上其他大城市的空气质量都很差，影响了居民的生活。这种低质量的空气是由看不见的污染物造成的，包括小于2.5微米的颗粒物质（PM）。造成空气污染的一个主要因素是车辆的排放。此外，农业燃烧、森林火灾和工业加工也是空气中微粒物质的重要排放者。空气污染是许多疾病的原因，如呼吸道和心脏疾病，以及肺癌，导致全世界每年多达700万人死亡。空气质量问题是一个重要的挑战，必须加以解决，以提高城市居民的生活质量。

The Common Air-rea – Re-envisioning Public Space in the Age of Air Pollution – At the present, Bangkok, and other big cities around the world, are suffering from poor air quality which has affected the livelihood of their inhabitants. Such low quality of air is caused by invisible pollutants, including Particulate Matter (PM) smaller than 2.5 microns. A major contributor to air pollution is the emission from vehicles. Additionally, agricultural burning, forest fires, and industrial processes are also important emitters of airborne particulate matters. Air pollution is the cause of many illnesses such as respiratory and heart diseases, as well as lung cancer, leading to as many as 7 million deaths per year around the world. The air quality problem is an important challenge that must be addressed in order to improve the quality of life of city dwellers.

为了应对这一挑战，云层设计并建造了Common Air-rea，作为曼谷设计周2021的一部分，我们在半开放的公共空间中展示了缓解空气污染和改善空气质量的可能性。作为该项目的赞助方，创意机构经济（CEA）所面临的挑战是，云地板要创造一个空间，让游客能够呼吸到更清洁的空气，减少空气中的微小灰尘颗粒带来的危险，同时，他们仍然感觉自己是在一个开放的公共空间。

In order to address this challenge, Cloud-floor designed and built the Common Air-rea as space where we showcased possibilities in mitigating air pollution and improving the air quality in a semi-open public space as part of the Bangkok Design Week 2021. The challenge from the Creative Agency Economy (CEA) as the patron of the project was for Cloud-floor to create a space where visitors would be able to breathe cleaner air, reducing the risk of danger from tiny dust particles that were airborne outside, while still feeling as if they were in an open, public space.

Common Air-Rea作为信息中心、会议点和2021年曼谷设计周的与会者的休息区。此外，这个空间还被用作空气净化机制的实验，该机制由混合动力系统驱动，即使用太阳能与传统来源的电力相结合。这个空间被半透明的滤光窗帘所包围。它们不仅防止空气污染进入内部环境，而且还作为一个过滤系统，过滤来自外部环境的光和热。然而，窗帘仍然允许日光进入，以提高建筑内部的能见度，并为空间提供一种公共性的感觉。

The Common Air-rea served as an information center, a meeting point, and a resting area for the attendees of the Bangkok Design Week 2021. Additionally, this space was used as an experiment for an air purification mechanism that was powered by a hybrid power system, i.e. using solar power in conjunction with electricity from traditional sources. This space was enclosed by translucent, light-filtering curtains. They not only prevented air pollution from entering the inside environment but also served as a filtration system for light and heat from the outside environment. However, the curtains still allowed for daylight to enhance the visibility inside the building and to provide a sense of public-ness to space.

建筑的这一绿色区域由空气净化植物组成，这些植物具有吸附灰尘的能力，可以捕捉空气中小于10微米的颗粒，并保留其他空气污染物。此外，该馆还包含了能产生吸引人的气味的植物，这有助于为空间创造一个更轻松的氛围。

This green zone of the building consisted of air-purifying plants that had dust-retention abilities to capture airborne particles smaller than 10 microns and to retain other air pollutants. Moreover, the pavilion also contained plants that produced appealing scents, which helped create a more relaxing atmosphere to space.

此外，这座建筑还配备了一种技术，可以捕获灰尘颗粒并将净化的空气循环到内部。没有实体的可关闭的门，这为与会者提供了一种开放和公共的感觉。相反，我们在入口和出口处使用了有助于控制空气循环的空气幕，防止外面未经净化的空气和污染回流到建筑内。封闭结构、绿色空间和空气净化技术的设计组合作为一个原型，为公共空间开辟了新的设计可能性，例如等待区、公共汽车站、户外市场，以及在任何公共空间为游客提供一个清澈的空气避难所。

Moreover, this building was also equipped with a technology that trapped dust particles and circulated purified air into the inside. There were no physical close-able doors, which provided a sense of openness and public to the attendees. Rather, we used the air curtain at the entrance and exit that helped control air circulation, preventing the unpurified air and pollution outside from flowing back into the building. A design combination of the enclosed structure, the green space, and the air purifying technology served as a prototype that opens new design possibilities for public spaces, e.g. a waiting area, a bus stop, an outdoor market, and in any public space that has a clear-air sanctuary for visitors.

公共空气净化器的屋顶结构配备了一个太阳能系统，使该建筑能够使用替代能源。太阳能被储存在电池中，以便与传统来源的电力相结合，在曼谷设计周期间为Common Air-rea的空气净化系统、空气幕、照明系统和手机充电站供电。这个原型可以扩大规模，并进一步应用于其他开放空间环境。

The roof structure of the Common Air-rea was equipped with a solar energy system that enables the use of alternative energy in this building. The solar power was stored in batteries in order to be combined with electricity from traditional sources in order to power Common Air-rea’s air purification system, the air curtain, the lighting system, and the phone charging station during the Bangkok Design Week. This prototype can be scaled and further applied to other open-space settings.
