We can’t believe the Multnomah County East County Flagship Library Project is finally complete! This gorgeous new public library, designed by Holst Architecture and constructed by Fortis Construction, focuses on community input and impact. Alliant Systems, a design-assist partner to Fortis, has led the plumbing, HVAC, and piping systems coordination and installation for the project. Special features include radiant flooring, AERMEC Air to Water Heat Pumps (AWHP), two-pipe slab recessed Jaga forced air convection units, AAON Air Handing Units (AHU), beautiful plumbing fixtures and features, hydronic piping and more.
This project was a CLT challenge and took a large BIM coordination effort from our in-house modeling team. Significant effort was taken to coordinate prefabricated pe*******on locations in the CLT decking, and it was crucial to keep our mechanical and plumbing systems hidden to let the CLT be the main feature of the space.

Shout out to our site team for their wonderful work: Chase Purtzer – Project Manager, Brian Young – Plumbing Foreman, Rykeir Smith – Fitting Foreman, Dustin Martin – Sheet Metal Foreman, and Adam Jarvis – Project Start Up.

Alliant Systems’ Building Performance Services Team is proud to have supported Fern Ridge School District in securing a round one award through Oregon’s Early Compliance Action and Planning Program (ECAPP), helping the district get ahead of the state’s new Building Performance Standards (BPS).

Passed under House Bill 3409 in 2025, Oregon’s BPS requires large commercial and multifamily buildings to benchmark and report energy use, with the first compliance deadlines beginning as early as 2028.

This incentive helps offset early planning costs, including:
✔️ Energy benchmarking and reporting
✔️ Energy audits
✔️ Energy management and O&M planning
✔️ Steps toward full compliance

Congratulations to our Building Performance Services Team and Fern Ridge School District on this achievement!

Another round of ECAPP funding is launching soon, now is the time to start planning. https://lnkd.in/diS7yQ-2
