Pacific Garden Mission is a 3-story, 156,000 sf rescue mission serving homeless men and women. The new building at 14th Place and Canal is a replacement (not without controversy) for the organization's two existing locations that serve men and women separately, including the location at 646 S. State with the iconic sign (which is planned to be relocated). The new facility will house nearly 1,000 beds, serve 180,000 meals a month, and include gymnasiums, classrooms, library spaces, and all of the food and laundry services required to support such a massive operation.
The extreme complexity of this building demonstrates that green building goals can be pursued on any type of project. Because of the building's at-risk population, movement through the building and many details must be very carefully planned - green building is just one of many items on the design team's plate.
The project is pursuing LEED Silver certification, mostly with typical off-the-shelf technologies and strategies. An example of this is the use of dual-flush valves on toilets to contribute toward water savings. This type of product is essentially an exact substitute for a standard flush valve and is therefore very simple and effective to include in the design.
Food-producing greenhouses attached to one side of the building give this project a more literal green element. In addition to supplementing the mission's food supply, residents will participate in the gardening, providing rehabilitation and possibly job training. The greenhouses will also produce compost for sale.
Much of the projected energy savings (33% over an energy-code compliant building) come from the mechanical system. One unusual approach that saves both initial and operating cost is the sizing of the cooling systems - the systems for much of the building are sized to only temper the space, perhaps to 80ºF, on the hottest days. The air systems also use activated carbon filters (just like your home aquarium) to control odors while reducing outside air requirements (thus saving energy). A heat pipe heat recovery system also reduces energy cost - this is an application not frequently seen in Chicago and usually reserved for laboratories or other uses with hazardous exhaust.
Finally, the project does have some more easily visible green elements, including a green roof and solar thermal panels for domestic water heating. Given the large amount of hot water used for showering and food service, this is a great application of solar thermal. 100 of the panels were donated by the Chicago Department of Environment.
Pacific Garden Mission is scheduled for completion in late 2007 and is currently featured in the Sustainable Architecture in Chicago exhibit at the MCA. Other project team members include MEP engineer Lehman Design Consultants, LEED consultant and commissioning agent J.T. Katrakis & Associates, general contractor Walsh, structural engineer The Structural Shop, civil engineer Daniel Creaney Company, landscape designer Peter Lindsay Schaudt, lighting consultant Schuler Shook, roofing consultant Building Technology Associates, and food service consultant TriMark Marlinn.
