First in nation: Utah's tallest skyscraper will forecast air quality with LED lights
SALT LAKE CITY () — Much like how the Walker Center sign forecasts the weather, the Astra Tower, Utah's tallest skyscraper, will soon start forecasting air quality along the Wasatch Front.
Using real-time air quality data, LED lights atop the Astra Tower will provide an 'easy-to-understand' forecast for air quality in Salt Lake City. Officials say it's a first in the United States as cities typically feature buildings with lights that reflect the weather but not air quality.
The rooftop lights will begin illuminating Salt Lake City's skyline starting Thursday evening, Feb. 20. As air quality worsens or improves, the light will change.

An orange light will signal the air is unhealthy for sensitive groups and precautions should be taken while red, purple, and maroon lights will indicate hazardous conditions, encouraging Utahns to stay inside.
Officials with the (UCAIR) say the light will provide an easy-to-understand forecast and a reminder that what we do impacts Utah's air quality. UCAIR adds the system will be the first in the nation to communicate air quality conditions in real time.
'Improving air quality requires all of us to act,' said Lindsie Smith, executive director of 'This lighting system is a striking visual tool that highlights the importance of our collective efforts to help clear the air.'
Ed Lewis, the CEO of Kensington Investment Company which owns and operates the Astra Tower, said its partnership with UCAIR will be a 'meaningful step' to improving air quality and healthier living in Salt Lake City.
