The computer science facility at York University provided Busby and Associates Architects with the opportunity to demonstrate that a “green building” approach is viable in colder climates. Building materials were selected for low embodied energy and reduced construction waste including the specification of high volume fly ash for most of the building s concrete elements. The experience with high volume fly ash concrete in this project was very positive. The original goal of 50% fly ash replacement was reached for the majority of cast-in-place structures and the use of EcoSmart concrete resulted in an attractive finished product excellent workability with no disruption to the construction schedule and no added costs.
