Road Noise Disturbs the Peace at Portland Law Firm

Case Study

When Portland law firm SBH Legal purchased their office building in 2021, they immediately noticed the road noise. Built in 1925, their 15,741 sq. ft. building faces the busy I-405 freeway on the building’s west side. “We were having to modify how we did our court cases and our depositions,” said SBH Legal Managing Partner, Krishna Balasubramani. “We had to avoid the west-facing offices, which wasn’t going to be tenable in the long-term. It was a big issue for us.”

SBH Legal learned that their noise issues could be solved while also improving their overall efficiency. The building’s 90 existing single-pane windows offered little resistance to outside noise, which means they were also susceptible to unwanted heat loss in the winter and heat gain in the summer. These weak spots in the building envelope made the building noisy and uncomfortable while forcing the HVAC system to work harder to maintain interior space temperatures. While a full window replacement would be disruptive and cost-prohibitive for SBH Legal, they discovered a cost-effective, easy-to-install alternative called secondary windows.
