Sustainable Built

draft2 拷贝.png

Buildings consume ~40% of the total energy in US. The disruptive technologies for energy efficient buildings need to be aided by advances in material design. Energy efficient building materials can largely cut down energy usage in buildings and facilitate a paradigm shift in building design. In addition, most building materials not only have a high embodied carbon footprint, but also store no or minimal amounts of carbon. We aim to establish the fundamental knowledge needed to utilize carbon negative materials in buildings.

Energy Water Nexus


Trees are natural energy-water systems. The wood trunk is composed of numerous aligned fibers along the wood growth direction that are responsible for water and ion transport from root to leaves. We aim to establish the knowledge base of cellulose-water-energy interactions towards transformative discoveries.
