Ecologically Efficient
Water conservation takes center stage, as the Puyallup River watershed-an amenity vital to Puyallup's culture and livelihood-is threatened by population growth and current development practices. A demonstration green roof has 3 different levels of efficiency to show the benefit of rainwater management: standard roof, 2-inch roof and 4-inch roof. Rainwater run-off from each area flows into individual vertical cisterns exhibited on the building's facade. A sensor-controlled LED-light system displays the quantity of water in each cistern, which is then released in a visual and auditory cascade to a cistern below the plaza, providing a non-potable source for irrigation.
Puyallup City Hall is 20% more efficient than required by Washington code. The building's top sustainable features purposely engage and educate the public about their role in shaping Puyallup's smart growth future:
- Comprehensive rainwater system
- Demonstration green roof with vertical cistern display
- Excellent indoor environmental quality
- Natural daylight with monitoring and controls
- Natural ventilation with operable windows
- Public open space expansion
- Sunshading
- Transit-oriented, urban infill development
- Underfloor aid delivery
- Urban tree canopy renewal
