GRIHA (Green Rating for Integrated Habitat Assessment) is India's national rating system for green buildings, developed by TERI (The Energy and Resources Institute) and endorsed by the Ministry of New and Renewable Energy. With water scarcity becoming a critical concern across India, water management has become one of the most crucial criteria for achieving GRIHA certification. Smart water metering plays a pivotal role in meeting these requirements.
GRIHA evaluates buildings across multiple criteria including site planning, energy efficiency, water management, sustainable building materials, and indoor environmental quality. Buildings can achieve ratings from 1 to 5 stars, with 5 stars representing the highest level of sustainability. Water management alone can contribute up to 12-14 points towards the total score.
GRIHA's water management section focuses on reducing water consumption, maximizing rainwater harvesting, treating and reusing wastewater, and ensuring efficient water monitoring. Here's how smart water metering directly addresses these requirements:
This criterion requires buildings to reduce freshwater consumption by 25-40% compared to baseline. Smart water meters enable precise measurement of consumption patterns, identify wastage areas, and track the effectiveness of water-saving measures. Real-time monitoring helps facility managers make data-driven decisions to reduce demand.

Buildings must treat 100% of wastewater on-site and reuse at least 50% of treated water. Smart metering of both inlet water and treated water outflow ensures accurate tracking of treatment efficiency and reuse percentages required for documentation.
Smart meters can monitor rainwater collection volumes, track storage tank levels, and measure harvested water usage. This data is essential for GRIHA documentation showing that rainwater meets a minimum percentage of total water demand.
Regular water quality monitoring is mandatory. Advanced smart metering systems can integrate with water quality sensors to provide continuous monitoring and automated reporting for compliance documentation.
GRIHA recommends sub-metering for different water uses including domestic consumption, HVAC cooling towers, landscape irrigation, and process water. Smart meters make this economically viable by eliminating manual reading costs while providing granular data for each water use category.
GRIHA requires ongoing performance monitoring post-certification. Smart water meters provide automated data collection, cloud-based storage, and reporting features that simplify annual compliance submissions. The MeterSync platform offers ready-to-use GRIHA compliance reports.
Water loss through leaks can significantly impact GRIHA scores. Acoustic leak detection in smart meters identifies underground leaks before they become visible, helping maintain the water efficiency levels required for certification. Buildings using smart metering typically achieve 25-30% reduction in non-revenue water.
GRIHA requires comparison against baseline water consumption. Smart meters store historical data enabling accurate benchmarking, trend analysis, and demonstration of continuous improvement—all essential for maintaining and upgrading GRIHA ratings.
While all three certification systems emphasize water efficiency, their specific requirements differ:
Smart water metering solutions from Greenify are designed to meet requirements of all three certification systems, providing flexibility for buildings pursuing multiple certifications.
