New Product Preview Advertising Section Chicago’s Pacific Garden Mission Built for Comfort and Efficiency It was necessary that the HVAC footprint be minimized to allow space for the solar panels and the green roof. Reid Woods, CES Group™ representative, Midwest Applied Solutions, Inc., proposed the solution: evaporative cooled condensers and an array of multiple supply fans using FANWALL TECHNOLOGY®. The system finally selected was an integrated Prefabricated Equipment Center (iPEC™) manufactured by Mammoth, Inc.®, a CES Group company. “The iPEC came to the jobsite in four sections and each section was bolted together in place on the roof. We really liked the concept of a prefabricated assembly arriving on the jobsite. It mitigated a lot of jobsite risk and helped to keep us on schedule since we had a tight construction timeline,” says David Lehman, President of Lehman Design Consultants, Inc. Supplying air to the VAV system is a 12-fan FANWALL® array. Each fan has a 10 HP high efficiency motor that operates at 80 Hz at design with a variable frequency drive. Says Lehman, “We can’t believe how quiet the supply FANWALL array is inside the unit…You can be standing right next to the discharge of 70,000 cfm of supply air with 120 HP in motors and carry on a conversation with someone. The FANWALL array gives better energy efficiency than two large plenum fans, and was much quieter—eliminating expensive sound abatement devices and their inherent cost increase.” The combination of green building practices and the sophisticated HVAC system ensured a comfortable and hygienic environment. hicago’s Pacific Garden Mission, a center dedicated to helping the homeless, constructed a new building in 2007 utilizing green design principles and with LEED® Silver certification as a goal. The new 156,000 square foot building was designed and built using state-of-the-art building practices and renewable energy technologies. C Discuss. Design. Deliver.
