Building blocks of future

India's new building codes—ECSBC and ENS—promote sustainable construction by enhancing energy efficiency, renewable integration, water conservation, and waste management, setting a path toward greener and efficient building paradigm

India has taken a major step toward a greener future with the introduction of two new building codes: the Energy Conservation and Sustainable Building Code (ECSBC) for commercial structures and the Eco Niwas Samhita (ENS) for residential properties. These new codes focus on making large buildings more energy-efficient, eco-friendly, and comfortable. They apply to large commercial buildings and multi-storied residential complexes with a connected electricity load of 100 kW or more, which means the codes will impact big offices, shopping malls, and apartment buildings.

Decoding the ECSBC and ENS The ECSBC and ENS are far more than mere updates to existing regulations; they represent a comprehensive and holistic approach to sustainable construction. Key provisions include:

► Energy efficiency: Stringent energy performance parameters are set for various building components, such as air conditioning systems, lighting, and appliances. The codes encourage the use of energy-efficient technologies and materials, driving down operational costs and carbon emissions.

The goal is to make large buildings use less electricity. Think of your home or office where air conditioning, lights, and appliances are running all day. The new codes require that these systems use energy more efficiently. For example, air conditioners must have better energy ratings, and lighting should rely more on energy-saving LED bulbs instead of older, power-hungry alternatives. Modern windows that block heat while letting in light are also encouraged. This means lower electricity bills and a reduced carbon footprint, which benefits both building owners and the environment.

India's new building codes offer a blueprint for creating greener, healthier, and more efficient buildings
