Evercloak, a Canadian materials-based cleantech innovation company, has developed breakthrough graphene-composite membranes that can greatly enhance the efficiency of building cooling. Current Air conditioning (A/C) systems consume a significant amount of energy, and it is predicted that A/C energy consumption will triple by 2050 due to various factors. However, Evercloak aims to reduce A/C energy use by over 50% by utilizing its innovative membrane technology with a potential greenhouse gas (GHG) emission reduction of 0.5 Gt/yr.
