Engineering Case Studies


The Center for Health & Healing at OHSU

Portland, Oregon
One of the first buildings to rise in a former shipyard in Portland is one of the most resource efficient large-scale buildings in the region, and one of the greenest in the country—the Center for Health & Healing. In fact, when the project was awarded a LEED Platinum Certification in 2007, the project received a total of 55 credits—three more than necessary for the designation. And with complete responsibility for the MEP design of the base building, tenant improvements, underground garage and central utility plant, as well as commissioning, Interface Engineering played a significant role in this achievement.

George W. Bush Elementary School

Stockton, CA
Originally designed in 1994, Interface responded to the need to bring the site-adapted building up to current Title 24 requirements by performing site work and applying energy measures that actually exceeded the stringent code standards by 21 percent. The majority of these energy savings were realized by exterior lighting and interior lighting modifications. Heating, ventilating and air conditioning (HVAC) contributed five percent of the energy savings compared to a base case HVAC. Additionally, Interface provided plumbing, fire sprinkler, site and building power distribution, lighting meter clock and classroom technology systems design for this project.

Clackamas High School

Clackamas, OR
Originally designed in 1996, the Clackamas High School project was considered "green" by sustainability standards of that time. Completed in 2002, the design for the 265,000 SF structure yielded a projected 57% energy savings over conventional lighting, thanks to Interface prescribing advanced lighting systems and controls that recently became available. This feature helped Clackamas High School earn a LEED® Silver certification from the U.S. Green Building Council. The new system works in concert with a design that takes advantage of the abundant daylighting specified by BOORA Architects. Interface also provided electrical design and commissioning services for this landmark project.

The Elsinore Theatre

Salem, OR
In 2002 $3.2 million was earmarked for a "Three-Act" restoration project for the Elsinore Theatre. Interface designed the HVAC system with a complete remodel. Interface's excellent partnership with the architect, mechanical contractor and plumbing contractor benefited the project by a synergistic meeting of the minds, leading to innovative solutions. Keeping it simple was everyone's mantra, making for the best low cost solution. Considering the elements of a theatre, it is no surprise that noise level was a major concern. The ventilation system historically used tunnels under the auditorium with ducts large enough to walk in, making balancing air distribution a challenge. Read how Interface addressed the noise factor with a two-pronged attack.

ODS Health Plans Plaza

Milwaukie, OR
A LEED-EB Pilot Project, the ODS Plaza shows what can be done with updating an older building for adaptive reuse. Providing full MEP services for renovating a 1956 industrial building, Interface’s designers secured savings of approximately $50,000 in capital costs by designing the general office lighting to 30 footcandles instead of the standard 50 footcandles for the 50,000 SF building. The innovative lighting has a suspended trunking system with luminaires that criss-cross each other at various angles and on several planes. This "intentional disorganization" actually produces a uniform placement of direct lighting fixtures that accentuate the original dark wood, helping to make the ODS building a place that makes people say "Wow!" The building also features extensive daylighting and daylighting controls.

Sun MicroSystems Assembly Testing Facility

Hillsboro, OR
A six-month design and construction schedule is highly unusual, especially when it is for a $15 million, 88,000 SF building. But Interface employed new ways of approaching this task that would normally be allocated to a 12-to-18-month timeframe. We used both new and existing technology in better and different ways to solve extreme high-density power requirements, excessive heat loads in the manufacturing area and special lighting needs. Providing redundancy through backup HVAC equipment, a looped design for ductwork and 13 HVAC units operating in parallel are just a few examples of how Interface provided a versatile HVAC system for the heat-generating server testing area. With “time to market” a key consideration, Interface’s MEP design team pulled off the six-month fast-track schedule.
