Net Zero Energy Buildings (NZEBs) - 100% energy-efficient, sustainable buildings - can be a game changer, not only for India’s building sector, but also for the energy sector. NZEBs have lower energy demand than that of conventional buildings and produce at least as much energy as they consume in a year, through onsite renewable energy technologies. NZEBs are commonly grid-connected to save battery costs. This allows them to draw electricity at night and during cloudy days, and return an equivalent amount of electricity to the local grid on sunny days. Thus, it nullifies the net carbon emissions from buildings.
