What Your Cleaning Vendor's Sustainability Data
Actually Means for Your LEED Score
Six LEED O+M credits depend directly on what your cleaning vendor documents. Most FMs do not know which credits they are leaving on the table until the recertification audit.
Your cleaning vendor controls the documentation for a Green Cleaning Policy prerequisite and up to five additional LEED O+M credits. If they cannot produce it, your building cannot claim it.
Direct Answer
Your cleaning vendor directly controls the documentation for the LEED O+M Green Cleaning Policy prerequisite and up to five additional credits in the Indoor Environmental Quality category. If they cannot produce a written green cleaning program, a product certification list, equipment compliance records, and timestamped inspection data, your building is not earning those credits, regardless of how well the building is cleaned. The gap is documentation, not performance. For the full picture on what we track and report monthly, see our sustainability programs page.
The LEED audit does not ask how clean your building looks.
It asks for documentation. Inspection logs, product certifications, training records. Your cleaning vendor either has it or they do not.

millfac.comLEED and SustainabilityThe Documentation Gap Most FMs Do Not See Until Recertification
I have walked LEED-certified buildings where the cleaning vendor had no idea what LEED O+M meant. The building had earned its certification during construction and maintained it through periodic recertification. The facilities manager had been collecting the vendor documentation manually, building a file each year for the auditor. When the vendor changed, the documentation chain broke. The new vendor did not know what the old vendor had been submitting.
This is not unusual. The cleaning vendor is often the last party considered when an FM is thinking about LEED credits. The HVAC team knows about energy credits. The property management team knows about water metering. But the Green Cleaning Policy prerequisite and the four credits that follow it sit entirely in the cleaning program, and many vendors have never been asked to document any of it.
The result is that buildings lose credits they were earning, or fail to earn credits they should qualify for, because the vendor relationship did not include a documentation requirement.
The Six Credits and What Each One Requires
| Credit / Prerequisite | What the Vendor Must Provide | Documentation Format |
|---|---|---|
| Green Cleaning Policy (Prerequisite) | Written green cleaning program covering products, procedures, equipment, and training. No policy, no certification. | Written document, updated annually. Must be on file. |
| EQ Credit 3.3: Custodial Effectiveness Assessment | Regular cleaning inspections documented using a standard protocol (APPA or equivalent). Must demonstrate consistent quality measurement. | Timestamped inspection records, per zone, on a defined schedule. |
| EQ Credit 3.4: Green Cleaning Products and Materials | Product certification documentation showing 75%+ of products meet Green Seal GS-37/40/41/42 or EPA Safer Choice criteria. | Product list with certification status for each product. SDS sheets on file. |
| EQ Credit 3.5: Green Cleaning Equipment | Vacuum equipment meeting CRI Green Label standard. Auto-scrubbers that reduce chemical and water use. HEPA filtration standard. | Equipment spec sheets showing CRI certification numbers. Auto-scrubber usage data showing reduction versus baseline. |
| EQ Credit 3.6: Indoor Integrated Pest Management | Written IPM plan and records of any pesticide applications. Most cleaning vendors share responsibility here with the pest control vendor. | IPM plan document, application logs, product SDS sheets. |
| EQ Credit 3.7: Green Cleaning: Entryway Systems | Documented matting and entryway system protocol that captures outdoor contaminants before entry. Cleaning records for entry systems. | Floor matting specification, cleaning frequency records. |
The Green Cleaning Policy: Where Everything Starts
The Green Cleaning Policy is not a credit. It is a prerequisite. Your building cannot earn LEED O+M certification without it. And it lives entirely in your cleaning vendor's hands.
A compliant policy covers four areas. First, it identifies the products used and confirms they meet certification criteria. Second, it documents the cleaning procedures for different area types and surface categories. Third, it specifies the equipment used and confirms compliance with CRI Green Label and HEPA standards. Fourth, it documents the training provided to cleaning staff on green cleaning practices.
The MFS green cleaning program satisfies all four areas. It is a written document we maintain per account, updated annually, and available for submission to your LEED auditor on request. If your current vendor cannot produce this document, the building is not in compliance with the prerequisite.
Product Certifications: The 75% Threshold
The Green Cleaning Products and Materials credit requires that 75% or more of cleaning products meet an approved green standard. The approved standards are Green Seal GS-37, GS-40, GS-41, and GS-42, and EPA Safer Choice certification.
In practice, satisfying this credit requires three things: knowing which products you are actually using in the building (not which products you specified), confirming the certification status of each one, and documenting the percentage calculation for the auditor.
The calculation is based on annual cost of compliant products divided by total annual product cost, excluding only janitorial paper products and trash liners. Vendor substitutions mid-year without documentation can drop you below 75% without anyone noticing until the audit.
MFS maintains a product list with certification status for every product used at each account. When a product substitution occurs, the replacement product is required to meet equivalent or higher certification standards. The running documentation is available for your sustainability team without a special request.
Minimum share of cleaning product spend that must meet Green Seal or EPA Safer Choice certification for LEED O+M EQ Credit 3.4: Green Cleaning Products and Materials.
A product substitution mid-year without documentation can drop your building below the 75% threshold for EQ Credit 3.4. Most FMs do not find out until the recertification audit.
Equipment: What CRI Green Label and HEPA Actually Mean
The Green Cleaning Equipment credit has two main requirements for vacuum equipment. CRI Green Label certification means the vacuum has been independently tested to confirm it does not re-release soil into the air and does not damage carpet fibers. The certification number should appear on the equipment specification sheet.
HEPA filtration means the vacuum filter captures 99.97% of particles at 0.3 microns. True HEPA filters are a defined standard, not a marketing term. Equipment labeled "HEPA-style" or "HEPA-like" does not meet the LEED requirement.
For auto-scrubbers, the credit requires documentation that the equipment reduces chemical and water use compared to manual methods. SmartClean autonomous scrubbers generate usage data from onboard sensors that shows water applied per square foot per cleaning cycle. That data is the documentation the credit requires.
NMotion smart dispensers at Georgia Aquarium produce an additional layer of documentation: chemical usage per dispenser per day. For buildings where dispenser data can be compared to a pre-installation baseline, that comparison satisfies the chemical reduction documentation requirement more precisely than any estimate.
The Inspection Requirement: Why Shift Logs Are Not Enough
EQ Credit 3.3 requires documented custodial effectiveness assessments on a regular schedule. A sign-in sheet confirming a crew was present does not satisfy this requirement. A timestamped digital inspection record showing which zones were cleaned, what was found, and whether the result met the defined standard does.
The APPA Custodial Staffing Guidelines scoring methodology is the most commonly referenced protocol for LEED compliance. It rates areas on a 1 to 5 scale, where 1 is ordinary negligence and 5 is spotless. The credit requires that assessments are documented and that a process exists to address areas scoring below a defined threshold.
MillenniumOS generates a timestamped inspection record every shift, for every zone. The inspection record includes the score, any deficiencies noted, and corrective action if required. Across an entire account, this produces a continuous inspection log that an auditor can pull and verify. The record is not assembled retrospectively at recertification time. It exists already.
What to Ask Your Current Vendor
If you manage a LEED-certified building and you have never explicitly discussed LEED documentation with your cleaning vendor, ask these questions before your next recertification cycle:
Questions to Ask Your Cleaning Vendor
- 1.Can you produce a written green cleaning policy covering products, procedures, equipment, and training? When was it last updated?
- 2.Can you provide a current product list with the Green Seal or EPA Safer Choice certification status of every product used in my building?
- 3.What percentage of your product spend in this building meets the approved green certification criteria? Can you show me the calculation?
- 4.Do your vacuums carry CRI Green Label certification? What are the model numbers and certification numbers?
- 5.Do your vacuums use true HEPA filtration? Can you provide the filter specification sheets?
- 6.Do your auto-scrubbers generate water usage data? Can I see actual consumption numbers for this building?
- 7.Do you produce timestamped digital inspection records? Can I access inspection history for the past 12 months?
- 8.Have you ever worked with an LEED auditor or submitted documentation for an O+M certification filing?
How MFS Handles the Documentation
Every active MFS account receives a monthly sustainability report. It includes chemical usage by product, water consumption from scrubber equipment, product certification documentation for every product in use, training completion records by staff member, and the MillenniumOS inspection log.
For LEED-certified buildings, we format this data to map to the specific credits the building is pursuing. You do not receive a generic vendor sustainability document. You receive the documentation organized around what your auditor needs.
MFS programs are aligned with Green Seal GS-42 criteria and use EPA Safer Choice certified chemicals as default. We are pursuing CIMS-GB certification for Q4 2026. Where we use the language "aligned with" rather than "certified," that distinction is intentional and accurate. You should apply the same standard to your current vendor.
Frequently Asked Questions
LEED O+M (Operations and Maintenance) is the rating system for existing buildings. Where new construction credits focus on design and materials, O+M credits focus on how the building is operated day-to-day. Cleaning programs, energy policies, waste management, and occupant behavior all factor into O+M certification. The rating is maintained on an ongoing basis and must be recertified periodically, which means your cleaning vendor's documentation is a continuous requirement, not a one-time submission.
The Green Cleaning Policy prerequisite is required for LEED O+M certification. It is not optional. The policy must document the cleaning products and equipment used, the procedures for applying them, and the training provided to staff. In most buildings, the cleaning vendor is the responsible party for generating and maintaining this documentation. If your vendor does not have a written green cleaning program, your building cannot satisfy this prerequisite.
For the Green Cleaning Products and Materials credit, at least 75% of cleaning products must meet one of the following: Green Seal GS-37 for general purpose cleaners, Green Seal GS-40 for floor care, Green Seal GS-41 for hand soaps, Green Seal GS-42 for commercial and institutional cleaning services, or EPA Safer Choice certification. Your vendor should be able to provide the specific certification for every product used in your building, not just a general statement that they use green products.
The Custodial Effectiveness Assessment credit requires that cleaning effectiveness be measured using a documented protocol on a defined schedule. The LEED reference guide recommends the APPA Custodial Staffing Guidelines scoring methodology, which rates cleanliness on a 1 to 5 scale. Inspections must be conducted and documented regularly. MillenniumOS generates timestamped digital inspection records every shift across every zone, which satisfies this documentation requirement and provides an auditable record for recertification.
Yes, for two specific credits. The Green Cleaning Equipment credit requires that auto-scrubbers reduce chemical and water use. SmartClean autonomous scrubbers use variable-speed dispensing and onboard sensors to minimize both, and they generate usage data that can be submitted as documentation. The Green Cleaning Products and Materials credit also benefits because smart dispensers ensure consistent product dilution, preventing overuse that would skew your product consumption calculations.
LEED O+M certification is awarded for a five-year period and must be renewed. At renewal, you must demonstrate continued performance across all credits. This means your cleaning vendor's documentation is not a one-time collection effort. It needs to be continuous. Monthly sustainability reports with chemical usage, product certifications, training records, and inspection logs are the documentation infrastructure that makes recertification manageable rather than a crisis.
Stop assembling documentation at recertification time.
MFS delivers a monthly sustainability report to every account that includes the product certifications, inspection logs, water usage data, and training records your LEED auditor needs. The documentation exists already. You are not building a file every five years. You are pulling from twelve months of records.
