In the United States, green-certified building development has become more and more common. But did you know that China is actually the world’s largest green building market? In fact, China eclipsed the United States with more than 1 billion square feet of certified green, sustainable building space.
What’s also interesting is that China did this in half the time it took the U.S. – 10 years compared to 20 in America.
This is good news, considering that China is not only the world's largest construction market, it's also the largest emitter of greenhouse gasses. With a focus on meeting green building and other environmental standards, China has the potential to make steady progress toward meeting its Paris Climate Agreement commitments. Key to that is a big goal by the Chinese government to achieve 50% commercial green building certification by 2020. Big goals lead to big results. If met, China will represent half of the world’s green building floor space by 2020.
Building owners have been choosing wisely. In 2005, green buildings were just 2% of commercial construction in the U.S. Today, they are closer to 50%. We see a similar trend in China, with impressive adoption of the China 3-star rating system for green buildings.
More buildings will be needed to meet the massive influx of people moving into cities. In China alone, 300 million more people (equivalent to the entire U.S. population) will move to cities in the next 15 years. Since buildings consume 40% of the world’s energy, we also know that these buildings need to be green. Clearly, the future of buildings and the future of sustainability go hand in hand.
New China Focus
This week, I traveled to China to attend the 13th Annual International Conference on Green and Energy-Efficient Building. I learned about new focus areas from Dr. Qiu Baoxing, president of the Chinese Society for Urban Studies and former vice minister for the China Ministry of Housing and Urban and Rural Development.
Dr. Qiu has been one of China's earliest and strongest visionaries for green building. He's now calling for more vertical gardens to be designed into Chinese city buildings. Imagine building facades that incorporate plants and trees as tall as they rise. No matter if you live or work on floor 1 or floor 40, you would see nature outside in the form of natural vegetation. This type of design would be as much be eco-cool and eco-beautiful as it would be eco-functional. Vertical gardening would introduce nature into otherwise concrete urban centers. More vegetation would naturally absorb CO2 pollutants and convert them to oxygen and according to Dr. Qiu, help address the outdoor air pollution issues in China.
The "Human Spirit" in Green Buildings
Throughout the years, the China conference has been a valuable convening point for green buildings. This year, Dr. Qiu proclaimed that green buildings must embrace the "human spirit." I couldn't agree more, and was pleased to present to the more than 1,000 people gathered that we have new scientific evidence from The COGfx Study* series that green buildings not only save energy and water, they also improve human performance – they improve the health and productivity of people working in those buildings. This research by Harvard is changing the global conversation in the buildings industry.
By focusing on the human performance benefits of green building, in addition to the valuable energy and water savings, we can greatly expand the value proposition of green buildings. This can help accelerate sustainable building development in China and everywhere else.
Where can green building take us next? To continue the conversation, tweet me @JohnMandyck.
