The latest addition to Puyallup’s MultiCare Good Samaritan Hospital, the nine-story, $300-million Dally Tower, has received the Green Building Institute’s LEED Gold award.

The hospital tower, which doubled the space at Good Samaritan, is the state’s first hospital structure to win the high award for energy and resources conservation, said Tacoma’s MultiCare Health System, the hospital’s parent company.

The tower opened for patients a year ago. The hospital tower includes 78 patient rooms and a new emergency department for the hospital.

The gold award was based on the new building’s water and energy saving features including two green roofs, rain gardens and environment-friendly construction methods.

The architect for the project was the Good Sam Design Collaborative which included Clark/Kjos Architects and GBJ Architecture. Skanska USA was the general contractor.

Another area hospital serving southeast King and northeast Pierce counties, Enumclaw’s St. Elizabeth Hospital, last summer was awarded a LEED Silver designation. St. Elizabeth is owned by Tacoma’s Franciscan Health System.
