Large scale development of Net Zero Energy Buildings (NZEBs) is seen as a potential solution to deal with future energy challenges in the building sector. This article aims to assess the current status of NZEB development in India by using an integrated framework named Sectoral System Innovation Assessment framework (SSIAf). The article addresses the research question: "“What does the SSIA framework tell about NZEB niche formation in India?" The SSIAf is developed using insights from the theoretical frameworks of Strategic Niche Management (SNM) and Sectoral Innovation Systems (SIS) with five key components: shaping of expectations, social network formation, institutions, learning process and market demand. A case study research design was used to analyze seven NZEB demonstration projects in India. The results show that the NZEB innovation niche has yet to develop into a mature niche, and is growing only slowly.
