Q. Eco-Niwas Samhita (ENS), a residential energy conservation building code, was developed by which organization?
Answer:
Bureau of Energy Efficiency (BEE)
Notes: The Eco-Niwas Samhita (ENS) introduced the Residential Envelope Transmittance Value (RETV), a metric measuring heat transfer in buildings. It's a Residential Energy Conservation Building code by the Bureau of Energy Efficiency (BEE), setting standards for energy-efficient residential buildings. ENS 2018 (Part 1) focuses on envelope designs, while ENS Part 2 (ENS 2021) addresses code compliance and electromechanical systems. Lower RETV values lead to cooler indoor environments and decreased energy usage, aiming for an RETV of 15W/m² or less for optimal efficiency and comfort.
