Life Cycle Assessment of Residential Buildings: A Case Study in Canada
Life Cycle Assessment (LCA), Residential
The World Academy of Science, Engineering and Technology published this Life Cycle Assessment in the International Journal of Energy and Environmental Engineering. LCA methodology was employed to study the primary energy uses and associated environmental impacts of different phases (i.e. product, construction, use, end of life, and beyond building life) for residential buildings. Four different alternatives of residential buildings in Vancouver (BC, Canada) with a 50-year lifespan have been evaluated, including High Rise Apartment (HRA), Low Rise Apartment (LRA), Single family Attached House (SAH), and Single family Detached House (SDH). Life cycle performance of the buildings is evaluated for embodied energy, embodied environmental impacts, operational energy, operational environmental impacts, total life cycle energy, and total life cycle environmental impacts.
