In the fall, Preservation Chicago will be having what will no doubt be an incredible fundraiser at the Charles H. Shaw Technology and Learning Center (aka the old Sears Power Plant that underwent a $40 million dollar restoration and rehabilitation). The building originally supplied heat and electricity to the massive Sears, Roebuck and Co. campus on the city’s West Side, and is one of four main buildings of the George C. Nimmons designed Sears, Roebuck and Co. complex and was listed on the National Register of Historic Places in 1978. I’m on the Preservation Chicago board and pretended that it was necessary to tag along and scope out the venue because it’s something I have been wanting to do for quite some time now.
The 1905 structure in North Lawndale was originally 30,000 square feet (now expanded even further), and is a creative example of adaptive reuse that resulted from a partnership with Chicago Public Schools’ Renaissance 2010 project and the Henry Ford Learning Institute. The Power House was slated to become an energy efficient charter high school in what has been a terribly under-served area. I guess if you’re going to spend $40 mil, that’s a good place to spend it. Because of the unusual space and the way that classrooms were carved into the existing structure, the setup of each room is, well, atypical. I thought this was especially cool in that it helps break the hierarchy and traditional layout of classrooms and only reinforces the mission of the school and it’s progressive curriculum. For some reason, this analogy came to mind: if Stevie Nicks wasn’t spiritual on the inside, her lyrics wouldn’t seem as magical, right? Be kind, it’s Friday at 3:30 and I still have much work to do today.
While the website says that the building is aiming to achieve LEED Gold status, I was told on the tour that they may actually end up achieving LEED Platinum. While I love to raise a suspicious (let’s be honest, even condescending) eyebrow at the LEED rating system, the fact that this structure is used by thousands of people, and the fact that it is an adaptive reuse project makes me glad to see it is getting such recognition. The project architects were from Chicago–based Farr & Associates, who began the assessments in 2005. Work was completed in time for the 2009 school year. For more incredible historical, before, and after photos of the powerhouse, look here.
Here are some highlights of the building that I pulled from the website:
• Geothermal Heating and Cooling – The HVAC system capitalizes on a half-acre geothermal well field of 84, 350′-deep vertical ground loops circulating water with glycol to reject heat in summer and extract heat in winter. Coupled with an integrated DDC controls system and 42 individual water-to-air heat pumps the system will allow greater temperature control and reduced energy consumption.
• Energy Efficient Historic Windows – The historically regulated windows on the west and north facades are retrofitted with insulated glass, thus retaining the historic character of true divided lite windows, while simultaneously enhancing the energy performance.
• Movement and Control of Conditioned and Ventilation Air – Mechanical systems employ heat recovery and demand-based ventilation. Two energy recovery units on the roof will temper outside air intake with exhaust air utilizing an enthalpy wheel.
• Preservation – The walls of the Great Hall are lined with white glazed brick. Original terra cotta floor tiles were lifted and reinstalled as part of the new floor plan. The original 40-ton gantry crane and rail system remain in place and the skylights spanning the space were refitted with an energy-efficient, natural daylighting system. Large pieces of heating, cooling, and power generation equipment from throughout the building’s lifespan have been left in place, including sections of the original coal conveyor system, coal hoppers, a diesel generator and other “mementos” of the building’s history.
