这2年在我国北方从入冬到来年3月低，雾霾随时会吞噬这片大地。空气质量问题从未有过的严重，今天特分享一篇早年的空气净化方案，据说在印度印证过。下文是当初TED上的演讲文字版，文尾也有视频版（中文字幕），值得一看。
注意封面配图，就是一个人需要的绿植配置。
－－－正文－－－
With only three varieties of plants, we can "grow our own fresh air" indoors, to keep us healthy.
只要三种植物，我们就可以在室内“长出我们自已的新鲜空气”，来保持我们的身体健康。
Which are these plants?
这是哪三种植物呢？

绿色空间-三种植物
![]()
1. Areca Palm (Chrysalidocarpus lutescens)
* Works well in the day time
* Great for living areas
* One needs about 4 shoulder high plants/person
* Needs to be put outdoors once every 3-4 months
* The leaves of the plant need to be wiped everyday in Delhi and perhaps once a month in a cleaner city
* The soil used should be of vermi manure or use hydroponics
1．散尾葵
在白天净化空气的效率很高
对人们的生活空间有很大好处
一个人需要4棵同肩高的散尾葵
在印度首都德里需要每天清洗该植物的叶子，在比较干净的城市可能也要一个月清洗一次
使用富含腐质物粪肥的土壤或者无土栽培

2. Mother-in-law's Tongue (Sansevieria trifasciata)
* Converts CO2 into O2 at night
* One requires about 6-8 such waist high plants per person in the bedroom
* Leaves need to be wiped in the same way as the Areca Palm
* The soil used should be of vermi manure or use hydroponics
2．虎尾兰
在晚上可将二氧化碳转化为氧化
在卧室一个人需要6-8棵同腰高的虎尾兰
叶子和散尾葵一样需要清洗
使用富含腐质物粪肥的土壤或者无土栽培

3. Money Plant (Epipremnum aureum)
* Excellent for removing Formaldehyde and other VOC's
* Best grown using hydroponics
3．绿萝
清除甲醛及其他挥发性有机化合物的能力很强
最好使用无土栽培
How do we know this works?
我们是怎么样知道他们是有效的呢？
We have tried and tested these plants for 15 years at Paharpur Business Centre and Software Technology Incubator Park (PBC? - STIP) in New Delhi, India. It is a 20 year old, 50,000 ft2 building, with over 1,200 plants for 300 building occupants.
我们在印度的首都新德里的巴哈尔布尔商务中心和软件技术孵化园，对这些植物试验和测试了15年，那里是个有20年历史，5万平方英尺的建筑群，生长着超过1200种植物并有300人居住。
PBC? - STIP is rated the healthiest building in Delhi by the Government of India.
在新德里，这个地方被印度政府评为最健康的建筑群。
* Their study found that there is a 42% probability of increasing blood oxygen by 1% if one is inside the building for 10 hours.
他们的研究发现如果一个人在那里停留10个小时，那么他的血液含氧量有42%的概率增加1%。
Also, compared to other buildings in Delhi, the incidence of eye irritation reduced by 52%, lower respiratory symptoms by 34%, headaches by 24%, upper respiratory symptoms by 20%, lung impairment by 10-12% and Asthma by 9%. As a result of fewer sick days — employee productivity also increased.
另外，在新德里，相对于其他建筑物，人受眼刺激疾病发生率减少了52%，下呼吸道疾病减少了34%，头痛减少了24%，上呼吸道疾病减少了20%，肺部损害和哮喘分别下降了10-12%和9%。由于减少了患病天数，员工的工作效率也提高了。
* Study published on September 8, 2008 by The Govt. of India, Central Pollution Control Board and Chittaranjan National Cancer Institute, Kolkata, India
We conducted another experiment and sealed all fresh air and exhaust from the building for 6 weeks and found that that the air quality inside the building was better than outdoors.
在2008年9月8日，印度政府公开了这项研究。印度中央污染控制局和印度加尔各答的吉德伦金国际癌症研究所进行了另一项实验，封锁了该建筑物的新鲜空气和废气6个月，结果发现建筑物内的空气质量比外面的还要好。
We saved over 15% in energy costs as we did not have to inject 15-20 cfm of fresh air in to the building as suggested by ASHRAE – an industry standard.
我们节省了15%的能源成本，因为我们没有听取制冷与空调工程师协会（一个行业标准）的建议向建筑物注入15-20立方英尺的新鲜空气。
Our experience points to an amazing increase in human productivity resulting from using these plants to be >20%, and energy costs to reduce by an extraordinary >15%.
我们的经验证明一个惊人的数据，通过使用这些植物，人们的工作效率提高超过20%，能源成本减少超过15%。

Buildings and Climate Change
* World energy demand is expected to grow by 30% in the next decade.
* Buildings consume 40% of the world's energy.*
* In another 15 years, more than 60% of the world's population will be living
in cities of over 1 million inhabitants.
* There is a growing trend of having air-conditioned living and working areas, resulting in the increased need for fresh air which needs to be heated or cooled.
* ASHRAE rules require 15-20 cfm of fresh air per person for a healthy non-smoking building.
建筑物和气候变化：
世界能源需求在未来10年将增长30%。
建筑物消耗占世界能源消耗的40%。
下一个15年，60%多的世界人口将生活在超过1百万居民的城市中。
有空调的生活和工作的领域的增长趋势，导致需要不断增加被加热或被冷却的新鲜空气。
制冷和空调工程协会要求在一个健康的不吸烟的建筑物内，一个人需要15-20立方英尺的新鲜空气。
By "growing" fresh air indoors we can reduce the supply of external fresh air needed by air-conditioned buildings, while still meeting industry standards (ASHRAE) for healthy indoor air.
通过在室内“长出”新鲜空气，我们可以减少依靠提供外部新鲜空气的空调建筑，同时还能使室内健康空气达到行业标准（制冷和空调工程协会）
By reducing the supply of external fresh air, we achieve significant reduction in energy needed for heating and cooling buildings.
通过减少提供外部新鲜空气，用于给建筑物取暖和降温的能源也明显减少。
