SIERR Building at McKinstry Station

The Spokane & Inland Empire Railroad (SIERR Building) at McKinstry Station, built in 1907, was formerly a repair depot for the city’s first electric railway system. Designated a national, historic landmark in 2010, through McKinstry’s efforts, the SIERR Building survives as the largest, most intact example of an electric streetcar facility from its era.  McKinstry converted this turn-of-the-century building into our innovative, energy efficient Regional Inland Northwest headquarters, complete with green office space and retail tenants.  McKinstry will reside in 30,000 sq. ft. of the 68,000 sq. ft. building.

With a total project value of $20M, the renovated SIERR Building features energy efficiency systems including ground-source heat pumps, radiant panels and a rainwater harvesting system. Building envelope improvements were also performed to increase the energy savings. McKinstry self-performed all mechanical, electrical, data and audio/visual trades. In the facility’s data center, waste heat is recovered from the servers and distributed during cold seasons to serve perimeter heating needs and to reduce overall heating requirements. The server room is set up in a hot/cold aisle configuration which allows for warmer supply air temperatures to be delivered to the servers. This evaporative cooling method was used for the server room and requires no mechanical cooling. The newly refurbished facility is one of a handful of LEED® Gold-certified and high performing historical buildings in the United States. McKinstry’s Sustainability Consulting Group worked with the design and architecture teams to ensure all plans were consistent with the project’s environmental goals, and guided the construction team on green construction practices.

Consistent with McKinstry’s company-wide methods of green deconstruction, this project achieved our target of 95% demo material recycled, and we coordinated with recycling centers for acceptance of building materials. We identified material reuse opportunities, such as Habitat for Humanity, to donate reusable building materials to lessen pressure on recycling centers/landfills and reduce virgin material consumption. We removed and stabilized hazardous materials from the site (soil/ground water and asbestos containing materials) to reduce health risks from exposure of building occupants and wildlife to pollution, and we used an environmental consultant to remediate hazardous waste.

The SIERR Building project delivers a world-class historic renovation that embodies thoughtful sustainable strategies and approaches, transforms a dilapidated building into a community asset and establishes a clean tech hub for the Inland Northwest. This brick-walled facility on the shores of the Spokane River will be a shining example of how sustainable renovation can integrate efficiency measures into historic buildings that preserve our connection to the past.
