2015 Visionary Award for Leadership - Vulcan

The Seattle 2030 District has awarded Vulcan their 2015 Vision Award for Leadership for their innovative Stack House Apartments and Supply Laundry Project. This full-block development in South Lake Union is comprised of two newly constructed apartment buildings and the renovation of the 109-year-old landmark, the Supply Laundry Building for office and restaurant use.  An effort to meld modern sustainability with the area’s rich past, the project’s combination of sustainable design and historic preservation enabled Vulcan to take advantage of numerous cost-saving incentives while building important partnerships to tackle new innovations that provide examples for others to follow.  

Vulcan not only created a walkable, livable, workable space, but together with the City of Seattle Department of Planning and Development and Preservation Green Lab,  they championed two remarkable achievements. First, they helped pilot a new energy code compliance path based on energy performance they helped pilot a new performance-based energy code using the 2030 Goal for Energy Reduction as the target, giving Vulcan flexibility and cost savings while still designing and building well beyond energy code. and second, they partnered with Seattle Public Utilities to construct the city’s largest urban bioswales to clean stormwater before it enters Lake Union. Other strategies included one of the first reverse-cycle chiller installations in the City to heat domestic hot water. This system is two-and-a-half times more efficiently than conventional high efficiency gas boilers, rainwater harvesting for irrigation, and a very efficient VRF mechanical system for the renovated office space. The latest data indicates the larger of the two apartment buildings is performing at a 20 EUI. 

This fusion of old and new provides sustainably designed office, mixed-income housing, and retail space. Livability is further enhanced by a year-round community garden/ gathering space and public art installations from local artists. The combination of these amenities earns the development a walk-score of 94.  Optimizing building performance, incorporating community resources, and innovative green design help position this full-block development as a national model for success.
