On Tuesday, March 16, at 12:30 p.m., the ISE welcomed Waafa Baâbou, PhD candidate in environmental sciences at UQÀM. Summary of her presentation: Building construction is a major contributor to mineral and metal resource depletion, hence the need to evaluate usage against the budget that ensures the reserve is properly maintained. The study uses the concept of planetary limits to define an annual budget for resource dissipation until users fully adapt to other substitutes. Allocation approaches allow for the allocation of a budget to the building construction sector and to the life cycle of a specific building type. Supervised by Cécile Bulle (Strategy, Social and Environmental Responsibility Department, UQAM) and Mario Santana (Carleton University).
