1While the planet continues to endure high temperatures,a 60-square-foot shipping container is serving as a testing ground for passive,sustainable cooling solutions.An engineering team is utilizing the space to find and improve upon ancient cooling methods that don't generate any forms of greenhouse gas.

2Buildings require roughly 60 percent of the entire world's electricity,almost 20 percent of which is annually used to keep those structures cool and comfortable.As society deals with climate change's most severe effects,air conditioning systems' requirements are only expected to rise in the coming years—potentially generating a feedback loop that could worsen carbon emission levels.Finding green ways to lower businesses' and homes' internal temperatures will therefore need solutions other than simply boosting wasteful AC units.

3This is especially vital as rising global populations require new construction,particularly within the developing world.According to Omar Al-Hassawi,lead author and assistant professor in WSU's school of design and construction,this push will be a major issue if designers continue to rely on mechanical systems—such as traditional,electric AC units.There's going to be a lot more air conditioning that's needed,especially with the population rise in the hotter regions of the world.

4By improving their shipping container test chamber with off-the-grid,solar-powered battery storage,the team can heat their chamber upwards of 130 degrees Fahrenheit to test out their solutions while measuring factors such as temperature and humidity.The team particularly focused on using a passive cooling method involving large towers and evaporative cooling that dates as far back as 2500 BCE in ancient Egypt.In these designs,moisture evaporates at the tower's top,which turns into cool,heavier air that then sinks down to the habitable space below.

5 “It's an older technology,but there's been an attempt to innovate and use a mix of new and existing technologies to improve performance and the cooling capacity of these systems,” explained Al-Hassawi,who also envisions changing smokestacks in older buildings to work as new cooling towers.

6Research like this would really help.How can we address building design,revive some of these more ancient strategies,and include them in contemporary building construction? The test chamber becomes a platform to do this.

Ⅰ.Difficult sentence in the text

As society deals with climate change's most severe effects,air conditioning systems' requirements are only expected to rise in the coming years—potentially generating a feedback loop that could worsen carbon emission levels.在社會應(yīng)對氣候變化（帶來的）最嚴(yán)重的影響的過程中，空調(diào)系統(tǒng)的需求預(yù)計在未來幾年只會上升——這可能會產(chǎn)生一個反饋回路，使碳排放水平進一步提高。
