Sustainability in Built Environments
"The built environment touches all aspects of our lives, encompassing the buildings we live in, the distribution systems that provide us with water and electricity, and the roads, bridges, and transportation systems we use to get from place to place. Our research group focuses on research areas such as whole building life cycle assessment, Life cycle costing and Life cycle data for construction materials, Green buildings and sustainable building material research, sustainable management of wastewater and solid waste, drinking water treatment, air pollution and control etc.
Areas: Building Life cycle assessment, circular economy in construction, Sustainability assessment of buildings, building materials, machinery, and transportation Wastewater management, Drinking water treatment, solid waste management, air and noise pollution, water sensitive urban design, water pollution mitigation and management"
