|Completed in October, 2006, the $165 million, 400,000 GSF Oregon Health & Science University's (OHSU) Center for Health & Healing is an outpatient medical and research building encompassing a one block development located in Portland's South Waterfront neighborhood - and it's the first medical and research facility in the U.S. to receive LEED? Platinum certification (NC and Operations). "Located at the lower station of an aerial tram, the Center for Health and Healing (CHH) is the first building for Oregon Health and Science University?s new River Campus. Bringing the Science into spotlight, OHSU envisioned this building and its rooftop gardens as a way to offer cutting-edge health care and research environment for students and faculty, allowing them to blend teaching and discovery into unequaled patient-centered care," (Walker Macy Landscape Architects, 2009).|
The Oregon Health & Science University Center for Health & Healing employs a number of sustainability strategies, including photovoltaic arrays on its sunscreens, a trombe wall to collect and circulate solar heat, a gas-fueled power system, and a state of the art on-site wastewater treatment plant (membrane bioreactor - MBR) where 100% of wastewater is recycled for in-building toilet flushing, cooling tower water, and landscape irrigation, resulting in 60% reduction in potable water use.
|Three eco roofs and two intensive greenroofs were added for patient, staff and visitor enjoyment as well as part of the overall stormwater strategy. Walker Macy led the design of the roof gardens (6-8" augmented with raised planters containing 36" depth of growing media) and eco-roofs (3-4" of growing medium), streetscape, parking lot and temporary park on an adjacent block. Accessible intensive greenroofs are located off the 4th floor day patient's lobby as a restorative garden, and the 5th floor off the doctors' waiting areas which is open to staff, visitors and patients. The building is topped off with an non-accessible ecoroof on the 17th floor, and extensive gardens and office accessible balconies are located off the 15th and 16th floors. The total area of extensive greenroof is 7,802 sf and intensive greenroof is 6,970 sf, not including walking surfaces.|
"At the first meeting with the architects designing the Oregon Health and Science University?s Center for Health and Healing, developer Dennis Wilde posed a challenge: Reduce the capital costs for the building?s mechanical systems by 25% but make it outperform the Oregon energy code by 60%. For a simple, single-use building, Wilde?s goal would have been bold enough. But given the center?s unprecedented mix of swimming pools, a surgery suite, exam rooms, offices, and research labs?each with heating, cooling, and ventilation demands far beyond the norm?it was nothing short of audacious.
?It was impetuousness, plain and simple,? recalls Wilde, a principal at Gerding Edlen. ?We habitually build buildings full of mechanical equipment that?s seldom used. Why the hell not get creative?? What the team quickly discovered is that the proverbial sum, in fact, could be much greater than the parts, particularly if you make sure most of those parts serve more than one function. Designed by GBD Architects in close collaboration with Interface Engineering, the Center for Health and Healing is a lesson in the architecture of integration," (GreenSource Case Study, see below).
Managed by CB Richard Ellis, the Oregon Health & Science University (OHSU) Center for Health & Healing as an ENERGY STAR certified building and received The Outstanding Building of the Year Award (TOBY) in the medical office building category from the Building Owners and Managers Association (BOMA) in the 2010 international competition, the first for an Oregon facility.
