Environmentalists are concerned by the number of students using transportation services like Lyft and Uber to get to classes. Students at UCLA specifically use these alternative means of transportation around 11,000 times per week, and that is troublesome for a city that is already dealing with significant smog issues. “The  pollutants  coming out of the tailpipe heavily contribute to Los Angeles’ smog problem,” Yifang Zhu, a professor at UCLA, explained. Transportation staff at the university said that the majority of these trips are short in duration. Students who oversleep are also more likely to use Lyft or Uber, because they need to get to class in a hurry without being tardy. School officials believe this increase in traffic plays a part in the growing smog problem in Los Angeles. Related: Toxic smog causes school closures in Bangkok Part of the issue with these services is that the vehicles are idling for a significant portion of time before picking up passengers. In fact, the idling can sometimes contribute more smog that actually driving to the destination, which is troublesome for a densely populated city like  Los Angeles . According to The Washington Post , younger generations are more apt to use services like Lyft or Uber , because they have an aversion to owning their own vehicles. These services can be more affordable than purchasing a car, especially on a student’s budget. While economics is clearly a factor to consider, previous research shows that millennials are the driving force behind these ride-hailing apps. For example, a 2016 study conducted by the Pew Research Center discovered that around 25 percent of young adults between 18 and 29 years old had used services like Lyft or Uber. Adults over the age of 65, meanwhile, barely register at only 4 percent. Although it may be more environmentally friendly to not own a car or truck, using alternative transportation services can be just as damaging. The transportation staff at UCLA gathered the information by combing through data from Uber and Lyft, two of the most widely used services on campus. Via The Washington Post Image via Josh Saldana

Sydneys vibrant Green Square Library and Plaza collects and reuses rainwater

Former marshland in Sydney has been transformed into the new Green Square Library and Plaza, a striking project that’s not only revitalizing one of the city’s oldest industrial areas but is also a shining beacon for sustainability. Designed by Sydney-based architecture and urban design practice Stewart Hollenstein in association with Stewart Architecture , the Green Square project features a semi-submerged underground library with a plaza on top. Energy efficiency drove the design as well, from the numerous skylights that let in natural light to the library’s low-energy displacement ventilation system engineered by Arup. Created as a central gathering space for the growing Green Square neighborhood, the Green Square Library and Plaza draws the eye with its playful geometric cutouts and pavilions that punctuate the 8,000-square-meter plaza. The triangular-shaped glass pavilion on one end marks the entrance to the 3,000-square-meter underground library , while the large circular opening next to it brings light into the circular sunken garden at the heart of the library. Also on the plaza is a six-story glazed rectangular volume that includes a double-height reading room, computer lab, black-box theater, music room and community space. An outdoor amphitheater is found on the other end of the plaza. The four areas are visually connected with a series of 49 circular skylights that funnel light into the library, while the rest of the plaza is left open for other activities, from pop-up events on the lawn to a water play zone. Underground, the open-plan library is centered on a sunken garden with a children’s circle and “story tree.” Placing the library underground was no easy feat; because the project sits on former marshland, the area came with a permanent water table above excavation level. Waterproofing with four layers of defense was crucial to protecting the library from damage. The feat of engineering allowed for ample green space above — a key detail that earned the design first place in the global design competition for the public library.

At night, the skylights are illuminated to bring visual interest and safety to the plaza. Reduced energy usage is also achieved with Arup’s bookshelf-integrated displacement ventilation system that brings improved indoor air quality and greater cooling efficiency. The landscaping on the plaza was designed to manage stormwater runoff and capture rainwater for reuse in the library. + Stewart Hollenstein Images by Tom Roe and Julien Lanoo via Stewart Hollenstein
