Integrated System Packages For Deep Energy Retrofits In Commercial Buildings

Meeting energy and carbon reduction goals in the building sector calls for aggressive energy efficiency measures in both new constructions and existing buildings. This requires both savings depth (% energy reduction per building) and breadth (% of building stock addressed). This article presents opportunities and challenges for implementing deep energy retrofits in commercial buildings and describes research efforts to develop scalable energy efficiency packages. While the research is primarily targeted at the US building stock, it may offer useful insights for India's rapidly expanding building sector.

There is already a wide array of proven, commercially available energy efficiency technologies and strategies to achieve deep energy savings in new and existing buildings. According to the New Buildings Institute, there are almost 600 net-zero energy buildings in the United States [NBI 2019]. However, for most of the market, there remains a stubborn and persistent "adoption gap" for energy efficiency, i.e., the difference between the techno-economic potential and adoption of energy efficiency solutions is substantial. Various roadmaps and action plans over the years have identified a range of barriers and opportunities to address this gap [e.g., McKinsey 2009, CEC 2015], including awareness, cost-effectiveness, access to financing, workforce training, ease of use, etc.

Role Of Smart Meters In Energy Management

Energy metering in India has evolved over several years. Apart from energy accounting and revenue management, it plays a crucial role in billing efficiency, renewable energy integration and load management. The Government of India is now focusing on the need to adopt prepaid and smart meters to bring down the Aggregate Technical & Commercial (AT&C) losses.
