Purchasing environmentally preferable maintenance products is a great place to start improving your site's impact on the environment.  Some of the places you can apply this policy include janitorial cleaning and paper products, receptacle liners, hand soaps, office paper products, business and marketing materials, paints, building maintenance products (caulk, adhesives, etc…) and construction materials.  The guidelines below will help you establish your office's environmentally preferable purchasing policy, then wherever possible also recommend that tenants do the same.

Low VOC paints and Eco-friendly flooring options for build outs:  
Require that construction in your building uses only low VOC paints, low or no formaldehyde, non-aerosol, and with recyclable packaging when painting an office.  In addition, eco-friendly flooring option such as recycled ceramic tiles, reclaimed wood, or wood certified by Forest Stewardship Council harvested wood and eco-friendly furniture can be recommended. 

Eco-friendly Building Maintenance Products:
Require engineering and maintenance staff use caulks, adhesives, paints, etc. that have low or no VOC's and are considered eco-friendly (such as those listed on www.builditgreen.org).

Purchase EPEAT computers, notebooks and monitors.
Require that the management office purchases Electronic Product Environmental Assessment Tool (EPEAT) certified desktop computers, notebooks & monitors. EPEAT certified products are energy efficient and use lesser quantities of hazardous constituents.  Recommend the same policy to tenants.

Green Cleaning and Equipment Information:
Green cleaning practices will help maintain good indoor air quality, increase occupant health and comfort, assure a clean building, and provide a healthy environment for the janitorial crew.  When implemented, a green cleaning policy will minimize the property's impact on the local environment by utilizing environmentally safe, low-impact cleaning chemicals and practices in the building.  Green cleaning will improve indoor air quality and create a healthier facility for occupants and visitors.

Use of daily green cleaning products: 
The Majority of the cleaning products used should be third party certified either by Green Seal, UL-EcoLogo or EPA's Design for the Environment.  When third party certified products are not available, cleaning products must comply with California Code of Regulation maximum allowable VOC levels.  If third party certified products is not available, work with the janitorial provider or staff to research and use a more environmentally friendly product than the conventional version of the cleaning agent.  These products should be pH neutral and should be concentrates if at all possible, and avoid aerosols and powders.

Daily cleaning products should meet one or more of the following standards:

  • Green Seal GS-37, for general-purpose, bathroom, glass and carpet cleaners used for industrial and institutional purposes;
  • UL EcoLogo 2792, for cleaning and degreasing compounds;
  • UL EcoLogo 2759, for hard-surface cleaners;
  • UL EcoLogo 2795, for carpet and upholstery care;
  • Green Seal GS-40, for industrial and institutional floor care products;
  • UL EcoLogo 2777, for hard-floor care;
  • EPA Design for the Environment Program's Standard for Safer Cleaning Products; and/or
  • Cleaning devices that use only ionized water or electrolyzed water and have third-party-verified performance data equivalent to the other standards mentioned above (if the device is marketed for antimicrobial cleaning, performance data must demonstrate antimicrobial performance comparable to EPA Office of Pollution Prevention and Toxics and Design for the Environment requirements, as appropriate for use patterns and marketing claims).

Disinfectants, metal polish, or other products not addressed by the above standards should meet one or more of the following standards:

  •    UL EcoLogo 2798, for digestion additives for cleaning and odor control;
  •    UL EcoLogo 2791, for drain or grease trap additives;
  •    UL EcoLogo 2796, for odor control additives;
  •     Green Seal GS-52/53, for specialty cleaning products;
  •     California Code of Regulations maximum allowable VOC levels for the specific product category;
  •    EPA Design for the Environment Program's standard for safer cleaning products; and/or

Disposable janitorial paper products and trash bags should meet the minimum requirements of one or more of the following programs:

  •    EPA comprehensive procurement guidelines, for janitorial paper;
  •    Green Seal GS-01, for tissue paper, paper towels and napkins;
  •    UL EcoLogo 175, for toilet tissue;
  •    UL EcoLogo 175, for hand towels;
  •     Janitorial paper products derived from rapidly renewable resources or made from tree-free fibers;
  •    FSC certification, for fiber procurement;
  •    EPA comprehensive procurement guidelines, for plastic trash can liners; and/or
  •     California integrated waste management requirements, for plastic trash can liners (California Code of Regulations Title 14, Chapter 4, Article 5, or SABRC 42290-42297 Recycled Content Plastic Trash Bag Program).

The requirements for janitorial paper products and trash can liners that meet the minimum requirement by the Environmental Protection Agency for recycled content are:

Hand soaps and hand sanitizers should meet one or more of the following standards:

  •     No antimicrobial agents (other than as a preservative) except where required by health codes and other regulations (e.g., food service and health care requirements);
  •    Green Seal GS-41, for industrial and institutional hand cleaners;
  •    UL EcoLogo 2784, for hand cleaners and hand soaps;
  •    UL EcoLogo 2783, for hand sanitizers;

Use of chemical concentrates and appropriate dilution systems:   
Use a chemical proportioning system to accurately mix the concentrated cleaning reagents.  The systems are user friendly and require no manual measurement. Features include:

  • Closed dilution system.
  • Portion controlled/locked in system.  You cannot tamper with or change dilution rate.
  • System attaches directly to the faucet.
  • Easy slide bottle feature allows for quick product changes.
  • Instantly primes.  When disengaged, product instantly drains back into the container.  No cross contamination.
  • Each product is numbered and color coded for simplified use (the concentrated bottles and spray bottles are both color coded).
  • Educator system is more accurate over varying water pressure than gravity drip systems.
  • Upright bottle design will not leak or drip!

Floor Finishes
