News Digital Twins Could Help CRE Reduce Emissions In A Big Way – But First, The Technology Needs To Become More Accessible The push for greener, more sustainable buildings and cities has been around for years, but that enthusiasm does not appear to have made a dent in global carbon emissions. Energy agencies agree that residential and commercial real estate account for about 40% of global energy consumption and emissions. Advocates of digital twin technology say that by increasing the efficiency of the built environment through real-time, comprehensive monitoring, that number could come down. New flagship office towers and corporate HQs are more likely to take advantage of the efficiencies that could be achieved using a digital twin. But the greater challenge is posed by the sheer volume of aging building stock, which requires significant and costly repositioning to be able to achieve the same efficiencies.
