Introduction: Fiscal Incentives Drive India’s UPVC Revolution
India’s 2026 Energy Conservation Amendment mandates UPVC windows in all new commercial buildings, backed by tax rebates up to ₹2.1 lakh per property. With UPVC’s thermal efficiency reducing HVAC costs by 29%, this policy aligns with India’s pledge to cut building-sector emissions by 40% by 2030. This guide breaks down the updated rebate structures, compliance protocols, and hidden benefits for stakeholders.
