CREST responds to an urgent need to train the next generation of architects and engineers in meeting the triple-challenge of a climate resilient, energy secure and healthy built environment. These designers will oversee a doubling of current global built floor space in the Global South alone during their professional lifetimes; locking in carbon, energy and indoor-health footprints for up to 6 decades, thus affecting millions of lives. We are leveraging joint UK-India expertise via Newton and UKIERI research funding to address these challenges across three scales of design: novel building materials, climate extreme resilient building design and sustainable neighbourhoods.
