What Is ESG Compliance in Multifamily Housing?
ESG compliance in multifamily housing refers to the integration of Environmental, Social, and Governance principles into property design, operation, and reporting. It means not just building units and collecting rent, but also measuring and managing resources (energy, water, materials), ensuring resident well-being, and maintaining transparent and accountable governance systems.
For multifamily operators, this typically includes tracking and reducing resource usage, aligning with green building certifications like LEED or WELL, and reporting utility and sustainability metrics to stakeholders and investors.
Key ESG Pillars for Multifamily Housing
- Environmental: Reducing carbon footprint; improving energy efficiency; using water sustainably, e.g. via submetering, efficient fixtures, leak detection.
- Social: Promoting healthy living environments (air quality, water quality), resident comfort, access to amenities; ensuring affordability; engaging residents in sustainability.
- Governance: Transparent reporting of ESG metrics; meeting regulatory requirements; aligning operations with investor ESG goals; ensuring data integrity.
How Water Submetering Supports ESG Compliance
Water Submetering provides the granular, actionable data needed to support both the environmental and governance pillars of ESG. It enables property owners or managers to see where usage is high, detect inefficiencies (or leaks), and track performance over time, both for internal improvement and external reporting.
Water Submetering for Sustainability
- Accurate billing: Tracks water usage at the unit level rather than relying on a master meter that covers many units. This allows for more precise billing, visible conservation incentives for residents, and early detection of abnormal water usage (leaks).
- Proven savings: Studies show submetering can reduce water consumption by 15–30% in multifamily properties, based on a U.S. study of more than 8,000 properties across 13 cities in the western and southwestern regions and reinforced by HUD’s 2025 study on submetering in federally funded housing.
- LEED v5 alignment: Supports achieving LEED v5 credits. Under LEED v5, water metering and leak detection are required for new projects. Properties must measure total water use monthly for 12 consecutive months.
- Targeted retrofits: Provides granular data that can guide targeted retrofits, such as replacing inefficient fixtures or upgrading plumbing in high-consumption units.
- Resident engagement: Strengthens resident engagement by allowing residents to see their personal water use trends and encouraging conservation habits.
- Leak detection and accountability: Helps operators pinpoint hidden leaks that could otherwise lead to high costs and property damage, while also ensuring residents are accountable for their own consumption.
- Regulatory compliance: Meets emerging state and municipal requirements where water use disclosure or conservation mandates are tied to multifamily operations.
Smart Water Meters and ESG Goals
- Real-time visibility: IoT-enabled submeters provide live data on consumption patterns.
- Verified ESG reporting: Frameworks (such as GRESB) now require verified utility data, not estimates.
- Resident engagement: Smart Water meters also improve resident engagement by sharing dashboards and alerts while helping operators optimize systems.
- Operational efficiency: Enables predictive maintenance by identifying unusual consumption spikes before they escalate into costly repairs.
- Regulatory readiness: Positions operators to comply with stricter ESG disclosure mandates and green building codes that emphasize measured performance.
Green Certifications and Standards for Multifamily Housing
Certifications like LEED and WELL provide benchmarks for ESG compliance, requiring proof of sustainable practices such as submetering.
LEED Certification and Water Use (LEED v5)
LEED v5, introduced in 2025, set stricter requirements for water efficiency in multifamily housing. The update places greater emphasis on water metering and leak detection, ensuring that operators track and report water usage consistently. Submetering plays a critical role in providing the verified data needed for compliance. By meeting these requirements, properties not only achieve certification but also demonstrate accountability in water management.
- New prerequisites: Mandatory water metering and leak detection as baseline requirements.
- Performance tracking: Monthly monitoring of potable water consumption over a full year.
- Separate metering: Rainwater, greywater, and other alternative sources must be measured individually for transparency.
WELL Building Standard and Resident Health
The WELL Building Standard emphasizes resident health, focusing on water and air quality. Submetering supports WELL by providing transparent water data that ensures plumbing systems, filters, and storage remain effective. While WELL centers on occupant well-being, submeters strengthen compliance by verifying water management practices.
- Water quality assurance: Supports filtration and treatment systems by validating consistent performance.
- Resident trust: Builds confidence through transparent reporting of water usage and quality.
- Health-focused design: Reinforces WELL’s goal of creating living spaces that promote overall resident health.
