ASHRAE AWARD OF ENGINEERING EXCELLENCE

looking at site energy, and 29% less carbon than baseline
when looking at source energy.
It is understood that the environmental impact of
the building's operation will change over time due
to how electrical energy is sourced. Power to the site
is provided by Portland General Electric, which currently uses coal to generate 34% of the electricity it
produces. Oregon Senate Bill 1547 requires electric
companies serving customers in Oregon to eliminate
coal-fired resources from their electricity supply by
2030 and to use more renewable resources for energy
production. This " greening of the grid " will result in
the building having a lower environmental impact
over time.
Even though the energy use will not change, the
carbon produced in generating that same energy will
decrease. It also emphasizes the environmental benefits of using electrical sources over natural gas to meet
heating demands. The heat recovery chiller used in this
project is a good example of an effective way to shift to a
non-carbon-based heating source.

In addition to carbon emissions, water reduction was
an important environmental objective. Low-flow fixtures, including 1.28 gallons/flush (4.85 L/flush) toilets
and 0.125 gallons/flush (0.473 L/flush) urinals reduce
the potable water use by 300,000 gallons (1.1 million L)
annually compared to standard flow fixtures.
The project also uses a rainwater reclamation system, which takes advantage of Portland's abundant
water supply and uses rainwater collected on site to
flush toilets and urinals. Rainwater falling on the roof
is filtered and collected in a large cistern located in the
basement. The water is filtered again, sterilized via
ultraviolet treatment and distributed to flush fixtures in
the building. It is estimated that rainwater will reduce
potable water use by over 400,000 gallons (1.5 million L)
annually.

Conclusion
The success of this project stems from the cohesive
team environment and shared focus on one unifying
goal. By using a " Big Room " co-location strategy, open
communication, and collaborative knowledge sharing,
engineers and designers were able to select and vet systems in real time, designing a landmark LEED Platinum
laboratory building to support cancer researchers.
Ultimately, the goals of this project were realized
because of the team's dedication to the larger mission,
and the recognition that they were one component to
a broader goal: to detect cancer earlier, improve the health and morale of
patients, and in the words of the building's namesake, Phil Knight, " to end
