ASTRA/CST Contributions Towards Developing Low Carbon Alternative Building Technologies

The paper focuses on review of developments in low carbon building technologies since the inception of ASTRA/CST. Five decades of R&D and dissemination of alternative building technologies has been traced in three phases. The narrative highligts many building technologies developed, R&D work through doctoral programmes and sponsored research, capacity building and design of special courses. The impact of the low-C technologies on the construction industry, emission reduction and public investment on these technologies have been highlighted. The ASTRA/CST work ultimately resulted in over 4 million tonnes of carbon emission reductions. Apart from training many building professionals and the work provinded innovative topics for the doctoral reseach programmes at Indian Institute of Science.
