In 2006, Tufts University opened its first LEED Gold building, Sophia Gordon Hall. As part of the LEED process for that building, Tufts custodial contractor, One Source (now ABM) agreed to try using Green Seal certified cleaning products.
After one academic year, a graduate student evaluated the effectiveness of these new cleaning methods. She looked at cleaning efficacy, student satisfaction, and employee satisfaction and concluded that the green cleaning products and methods either showed no difference from the traditional cleaners or demonstrated improvement in each measure. The results were shared with Tufts Facilities Department and ABM.
As a result of this success and the evaluation, ABM decided to change all cleaning products to Green Seal products and green cleaning methods throughout Tufts University. ABM was also able to change from several cleaning products to one all-purpose Green Seal certified cleaner. The product change saves money and ensures that green cleaners are used consistently.
This project demonstrates how the LEED process can affect change well beyond just a single building.
