Opportunity

Phase I of the Wrigley confectionary facility is a two-story, new construction, 491,255-gross-square-foot food manufacturing facility. The facility was constructed on a previously developed site in a suburban area of Guangzhou, China. By constructing the factory on a previously developed site, Wrigley avoided affecting any prime farmland, habitats for any species that may be endangered, and undeveloped land that may be close to bodies of water. Phase I construction of the facility was awarded LEED® Gold by the U.S. Green Building Council (USGBC). Phase I utilized LEED® for New Construction™ green building rating system.

Challenges And Solutions

Wrigley set out with the intent to design and operate a sustainable production facility. Wrigley faced challenges during this process, the first being that food safety regulations require particular chemicals to be present in food production areas and any associated washrooms and locker rooms. This accounts for the majority of the facility, but Wrigley was free to select cleaning products for use in all other areas of the facility: the corridors, grounds, maintenance facilities and offices, among other areas. In these areas (as well as for unregulated cleaning products), Wrigley was able to install its own cleaning policies that would not conflict with international laws.

The local Chinese zoning code presented another challenge. The zoning code required open space not to exceed 19 percent. In order to meet the intent of Sustainable Sites Credit 5.2 Site Development – Maximize Open Space, Wrigley committed to keeping the maximum open space allowed by code after all planned expansions.

The project received a Regional Priority credit point by using landscaping materials that do not require permanent irrigation systems. The landscape design is based on local Chinese customs that incorporate native species of plants. Trees, shrubs and other non-grasses have been chosen that do not require regular watering beyond initial establishment.

 

 

Wrigley achieved exemplary performance in the areas of alternative transportation and use of regionally sourced building materials.

Building Highlights

  • An industrial facility generates large quantities of waste water, which Wrigley is required to process on-site. Rather than discharge the tertiary water, the waste water will supply the facilities cooling towers. In addition, condensate from the HVAC system is collected and rerouted to the cooling towers. With those systems, the non-potable water supply is expected to exceed 50 percent of the cooling towers’ requirements.
  • In preparation for Phase I being certified in the future under LEED for Existing Buildings: Operations and Maintenance, Wrigley is implementing several management policies in accordance with the LEED for Existing Buildings: O&M requirements. Because it is an industrial facility containing predominately fluorescent lighting, Wrigley is targeting an average mercury content per lumen of 45 picograms or less. In addition, Wrigley has established a mercury bulb recycling program which will dispose of all spent mercury-containing bulbs at an appropriate local facility.
  • The project team completed a pre-occupancy flush-out of the indoor space to protect the Indoor Air Quality. In addition, Wrigley used low VOC paints and adhesives and CRI Green labeled carpeting. The factory also installed permanent entryway systems to capture dirt and prevent particulates from entering the building at all regular building entry points.
  • Of the materials used to construct the factory, 22 percent contained post-consumer and 50 percent pre-consumer recycled content, based on total cost. In addition, 52 percent of the materials used were regionally extracted, harvested or recovered and manufactured within 500 miles of the project, based on total cost. These materials include structural steel, concrete and steel bars.
  • Wrigley will be operating a combination of free shuttle busses during shift changes to transport employees to and from mass transit stops near the employees’ neighborhoods. Between shifts, a dispatch van-pool service is used, operating door-to-door at no cost to employees. Five free shuttle lines run for each of the three factory shifts (continuously arriving before shift begins and leaving after the shift ends). Seven free shuttles arrive before the office shift begins and leave after the office shift ends.
