It’s hard, teaching sustainable design, as I do at Ryerson University in Toronto. The field is constantly evolving as we learn and as everyone becomes more focused on the climate emergency and carbon emissions. So whereas 20 years ago green building was all about reducing operating energy, now it’s all about carbon emissions of all kinds.
