New University of Utah study shows how outdoor pollution affects indoor air quality


SALT LAKE CITY — Ever heard of an air economizer? It’s something some HVAC systems have, and a recent study The University of Utah found in certain conditions these systems could impact indoor air quality.

“We get different kinds of pollution events here, especially wildfire smoke, winter time inversions and dust,” said Kerry Kelly, Associate Professor in Chemical Engineering At The University Of Utah

The College of Engineering teamed up with facilities management to put their research into action throughout Salt Lake City’s campus. “We spend about 80% of our time indoors, we find that wildfire smoke has the biggest impact on indoor air quality,” said Kelly.

Kelly explained that one of the key takeaways was the type of HVAC system that impacts indoor air quality. “Something called an air economizer we found that under certain conditions those can really dry in a lot of wildfire smoke,” said Kelly.

She explained what an air economizer does: “It’s more common on commercial buildings and it’s a really good strategy that can be really efficient. So, for example, you know it’s kind of hot here in the summer but at 3 o’clock in the morning the temperature is beautiful so at 3 o’clock in the morning, it can pull in more outdoor air because you spent a lot less energy conditioning.”

She explained it’s a good way to save energy, but not so great if it’s bringing in pollution.

So, what can you do then? “Particular matter sensors are pretty good. I mean it gives you a relative indication of what your indoor air quality,” said Kelly.

She also uses portable air filters, which you can find just about anywhere. “They can be really effective but if you decide to do one of these portable air filters, make sure that you only get air filtration. You just want a simple filtration device,” said Kelly.

The goal was Connor’s 300th in the NHL. He is the third player in Jets/Atlanta Thrashers history to hit the mark, behind Scheifele (353) and Ilya Kovalchuk (328).

“Just a pretty cool milestone,” Connor said. “Once you look back on your career, that’s kind of the stuff you’ll remember. But right now it’s focusing on winning, trying to be the best player I can, and helping out.”

Connor scored his second goal at 15:23 of the third period, beating Vejmelka blocker side with a one-timer to cut the lead to 3-2.

“I think we just knew that we needed to be better,” Connor said of the comeback. “I think we were on our toes more, jumping and making plays and hemming them in.”

Barron scored just 25 seconds later, beating Vejmelka glove side with a snap shot tie it 3-3.

“That first period was ugly. It was really ugly,” Winnipeg coach Scott Arniel said. “We got better in the second, certainly dominated in the third, but at the end of the day, you can’t play two periods in this league and look to have success.”

Crouse gave the Mammoth a 1-0 lead at 5:20 of the first period. Guenther skated in from the blue line and shot through the legs of Jets defenseman Logan Stanley to put the puck on Hellebuyck. The rebound of his shot then found Crouse in front, where he scored blocker side with a slap shot.

“We made it interesting on ourselves,” Crouse said. “Definitely not the way we wanted the third period to go, but credit to our group, that’s not easy. They scored two right away and then we went right into OT pretty much, so credit to the group for having the right mindset and being able to get the win.”

UDOT celebrates early opening of Mountain View Corridor connection to Utah County

UDOT celebrates early opening of Mountain View Corridor connection to Utah County


The Mountain View Corridor project connecting Salt Lake and Utah Counties was completed early, opening just in time for holiday travel.

The Utah Department of Transportation celebrated the early completion of the years-long project in a Friday event, with attendees able to walk the new road and take photos with Santa. The road and trails were opened to traffic after the event.

UDOT officials posted a video of the celebration, with the caption reading, in part, “This road and these trails are now yours.”

Commenters praised their work on the project—and the video itself—with some saying they’ve already driven on the new road.

“I almost cried when I went on the corridor today! It was done sooner than I thought so thank you!” one commenter wrote.

Another user called it the “best Christmas gift EVER!”

Some Utahns were less pleased, bringing up concerns about the lights not operating correctly on the north end or complaints about future construction.

However, the video itself addressed the negative comments UDOT receives, specifically complaints about constant construction.

“The truth is, if you want a DOT that never does anything and therefore never inconveniences you…Well, that just ain’t us,” the post read. “We don’t do construction to you, we do it FOR you, because we ARE you. We all live here too.”

The Mountain View Corridor project, also known as the 2100 North Freeway Project, was designed to improve east-to-west traffic flow between I-15 and Redwood Road in Lehi. It also included “shared-use-paths” for pedestrians and cyclists.

UDOT officials said Redwood Road is one of the most congested roads in Utah County, following Interstate 15 and Pioneer Crossing.

Officials expect this could reduce Redwood Road delays by 75% and also help alleviate I-15 traffic in the area.

The project began in Spring 2024, with construction expected to finish in Spring 2026. UDOT officials said the project was completed four months ahead of schedule.

In order to complete the road and trails, crews moved 1.5 million tons of dirt and paved more than 350,000 square yards of concrete and asphalt.

“This new stretch of Mountain View Corridor provides meaningful relief for drivers in fast-growing Utah County,” said Carlos Braceras, UDOT Executive Director. “Opening this stretch ahead of schedule improves regional connectivity and provides drivers with safer, more dependable travel options as the area continues to grow.”

While the new extension is complete, UDOT officials plan to continue to extend the Mountain View Corridor in the future. They said the goal is for it to be a 35-mile freeway connecting Interstate 80 in Salt Lake County to State Route 73 in Utah County.

The next phase of the project is planned to begin in 2027 and will address the stretch from Porter Rockwell Boulevard in Herriman to Old Bingham Highway in West Jordan.
