Green Operations

The Buildings Division uses Green Seal certified cleaning products in all city buildings.  Green Seal is a nonprofit organization that provides science-based environmental certification standards for a range of products.  Some of the certified products include glass cleaner, multi-surface cleaner, spot remover, restroom and shower cleaner, and multipurpose cleaner.

Additional green operations include use of recycled paper products, low VOC paints,  and HEPA filter systems.

Using environmentally-friendly products is good for the environment and for our staff that use them.  Green products contribute to a healthier indoor environment as well.

For more information on our Buildings Division, please visit the Public Buildings webpage.
