Utah's tallest tower to openly track air pollution

• Air quality data is vital to many residents. The Salt Lake City-Provo-Orem metro area ranks No. 9 in the U.S. for the worst ozone pollution, per an American Lung Association ranking released in April.

How it works: The building's exterior crown lighting will change color to reflect pollution levels — white for good or moderate air quality, and orange, red and purple for unhealthy pollution levels, per KSL.com.

• A sensor will also be connected to the elevator and lobby screens.
• The display aims to promote public awareness and change daily habits that could impact the environment.

Between the lines: The air quality beacon was inspired by the nearby Walker Center's weather tower, which glows in different colors to reflect the climate.

The latest: The 41-story luxury apartment building, which stands over 450 feet, had a ribbon-cutting ceremony Tuesday.

• It holds nearly 400 residences and more than 40,000 square feet of wellness amenities.
• The building features a pet spa, fitness center, yoga studio and urban park.

What they're saying: "Our goal was to create a place that elevates urban living while contributing to the health, vitality, and long-term sustainability of the city," Shane Rensmon, president of real estate development for Kensington Investment Co., the building's developers, said in a statement.
