Understanding PEGS’ 900-Point Scoring System

Most ESG ratings in real estate are binary: a building either gets a certificate or it doesn't. PEGS takes a different approach. Our 900-point framework allocates 300 points to each of three pillars—Environmental, Social, and Governance—and breaks each pillar into five parameters of 60 points apiece. Across all 15 parameters, 44 indicators carry the actual measurement: 18 environmental, 14 social, and 12 governance. The result is a nuanced profile rather than a pass/fail label.

Each parameter is anchored to clearly defined thresholds. The Energy Efficiency parameter, for instance, awards points for building-envelope thermal performance, on-site renewable generation, smart-meter penetration, and verified energy-use intensity (EUI) below benchmark. A building excelling in energy but lagging in waste management receives an honest, actionable score—not a misleading headline number.

Scoring is performed through a combination of document review, IoT sensor data ingestion, and periodic on-site audits. My Estatez automates much of this data collection by integrating with building-management systems, utility APIs, and municipal databases. This keeps assessment costs low while maintaining auditability—every data point is time-stamped and, where applicable, anchored as a SHA-256 hash on BASTION's permissioned blockchain.

The 15-parameter structure is designed for legibility against the standards Indian and global investors already track—GRI, BRSR, TCFD, GRESB, LEED, and BREEAM. PEGS is not derived from any of them. It is an independent framework that references each, so a single PEGS score is intelligible to a SEBI filing, a green-building certification body, and an international institutional investor without re-mapping. As regulations evolve, individual parameters can be re-weighted without redesigning the engine.
