Lighting controls have revolutionized energy efficiency, user experience and architectural expression. Occupancy sensing, daylight harvesting, dimming, color temperature tuning, individual luminaire addressing and third-party system integration are some of the countless advancements since the invention of the light switch by John Henry Holmes in 1884. The evolution of lighting controls has streamlined energy efficiency and safety in buildings, integrating emergency lighting systems with modern technology to enhance both functionality and aesthetics. Eric Rushenberg, senior lighting designer, has been featured in a new Consulting-Specifying Engineer article, explaining how to approach revised UL listing requirements when specifying emergency lighting controls. This article is a useful resource for understanding how: UL Standard 924 has updated its product listing requirements consistent with well adopted codes and standards, learning how control manufacturers are meeting requirements, ensuring products are individually listed and labeled whilst identifying a specification strategy for controlling emergency lights.

Is it possible to eliminate all roadway fatalities and serious injuries? The Safe System Approach has been used as a guide to try to accomplish that in communities around the world for decades. Learn more about how the method of rethinking roadway design to build a safer transportation system for all road users is gaining steam in North American in our latest Experts Talk interview with our senior transportation engineer Beth Wemple and traffic engineer Olivia Polinsky. https://lnkd.in/gnZ7cig3 #VisionZero #RoadSafety

When I-5 was built through Oregon in the 1950s, it divided Portland's historic Albina district and displaced many residents. Now the Rose Quarter Improvement Project is seeking to reconnect the community and mend some of that historic harm. Hear from HDR's John Wolf, Steve Drahota and Justin Doornink as they discuss the impacts of this transformational effort and share what it means to them.

More than 20 years after the first studies, the Council Bluffs Interstate System program in western Iowa is nearly complete. The $1.4 billion series of projects reconstructed 14 miles of interstate and drastically improved the junctions of I-80, I-29 and I-480. And it's finishing ahead of schedule and under budget. Congratulations to Iowa Department of Transportation and all those who dedicated years of their careers to this program's success. Watch the video at this link to learn more about this transformative project: https://lnkd.in/gPPK3Zgb

Pensacola employees and their families volunteered more than 175 hours in partnership with From the Ground Up Community Garden to design and build a tiered, mandala garden layout consisting of 16 revitalized garden beds under a previously abandoned underpass. With the support of an HDR Foundation Employee Network Group grant sponsored by Phillip Walker, PE, the new garden layout requires less strain for gardeners of all ages and better suits school field strips, music events and art exhibits. “Although it was hard work, our team is always grateful to be giving back to our community and building a place for our community to grow,” Phillip said.

Meet Greg Eberhardt, principal structural engineer based in Brisbane, Australia, where he leads the Queensland civil structures division. His work often includes inspections next to live traffic, in tunnels, on bridges, under bridges and in creeks, so safety is always at the top of his mind. “It can be very easy to cut corners with safety, but it's also easy for something to end in catastrophe,” says Greg. “Coming home to my family every night isn’t something I take for granted.” When he’s not working, Greg and his family are almost certainly enjoying the great outdoors—fishing in Moreton Bay, off-road driving on local beaches, or simply enjoying their garden with their dogs. Thank you, Greg, for the leadership you bring every day to help keep HDR safe at work and beyond. #SafetyMonth
