Inspiration The new station is located at the base of Queen Anne Hill on 15th Avenue NW, a major arterial that runs through the industrial zone connecting downtown with the Queen Anne and Ballard neighborhoods. Given the highly visible site, the City identified the project as an opportunity to create a civic presence for the Fire Department while setting a new high performance design standard for its facilities. Problem Solving The design addressed a number of interrelated challenges which included differentiating the station from its industrial and commercial neighbors, many with large garage doors; cutting through the steep topography to create a drivethrough apparatus bay; creating privacy for the firefighters’ living quarters adjacent to the busy thoroughfare; and the ambitious sustainable design agenda. A series of parallel concrete and concrete masonry walls in the north/south direction. They retain the hillside, organize the site, contain green infrastructure, and provide lateral resistance for the building. Steel-framed volumes that contain the program run over and between the masonry walls in the east/west direction. Their major openings are perpendicular to the walls and the street, maximizing daylight and views, reducing solar gain and shielding the living quarters from acoustic impacts.
Environmental The LEED Platinum certified project achieved 98 points, making it the highest-scoring fire station in the country. The building is designed for 70% energy savings, meeting the 2015 goals for the Architecture 2030 Building Challenge. Bio-retention planters and green roofs contain plants, soil and gravel which manage stormwater, cool the site, and integrate the masonry building walls with the hillside retaining walls. Heating and cooling is provided by geo-thermal wells. The heat-recovery unit captures 75% of the exhaust energy. Radiant floor and thermal mass in the apparatus bay reduce energy loss from opening the garage doors. A 35KV photovoltaic array on the roof provides 27% of the energy used by the station. Solar hot water heating, LED fixtures, and daylight harvesting increase the electrical energy savings. Social Transformation An interpretive program displays the station’s sustainable agenda. A low energy use flip-dot sign along the arterial is connected to the building’s control system and displays real-time information on energy, water and carbon savings. Interpretive signage around the station identifies and explains the site and building systems.

Retention of the site topography led to a series of masonry walls. These walls form the spatial organization of the building which intersect with the second level horizontal volume.
