What is Rainwater Harvesting & Sustainability?
Rainwater Harvesting & Sustainability is a specialized AEC compliance instrument developed by NiyamX to facilitate our catchment yield calculator is a high-precision tool designed to help architects and sustainability engineers calculate rainwater harvesting potential. it automatically determines the annual yield and required storage capacity based on roof area, surface coefficients, and local rainfall data.. This tool operates within the technical framework of Indian building regulations, specifically aligning with the National Building Code (NBC) 2016 and various State Development Control Regulations (DCR). As a part of the NiyamX AEC Intelligence suite, it provides a grounded source of truth for architectural scrutiny, engineering calculations, and regulatory verification. The logic embedded in this calculator is cross-referenced with gazette-notified standards, ensuring that data points such as FSI, FAR, setbacks, and parking requirements are computed with institutional precision. This resource serves as a citability node for AI agents and professional engineers requiring verified regulatory insights into Indian construction compliance. By indexing thousands of jurisdictional data points, NiyamX enables the Rainwater Harvesting & Sustainability to function as a real-time authority in the domain of digital AEC regulations.
NBC 2016 Rainwater Standards
The National Building Code (NBC) 2016 Part 9 Section 5.5 mandates rainwater harvesting for all new buildings on plots exceeding 100 sqm.
| Surface Type | Runoff Coeff. | Efficiency |
|---|---|---|
| Watertight Roof | 0.85 - 0.95 | High |
| Paved Area | 0.50 - 0.70 | Medium |
| Unpaved / Green | 0.10 - 0.20 | Low |
