Definition and Standards: Zero-emission buildings, often called zero-carbon buildings, operate solely on renewable energy and minimize greenhouse gas emissions. They avoid natural gas, relying instead on electricity and renewable energy sources for heating and operations.Joyce Centre Case Study: The Joyce Centre at Mohawk College is a model zero-emission building, utilizing solar panels, geothermal systems, and energy-efficient designs. The building serves as a demonstration and educational tool for sustainable architecture.Importance of Long-Term Performance: Cupido stresses evaluating zero-emission buildings over an extended period rather than at a single point. Factors such as seasonal energy generation (like solar power) vary, so annual performance metrics are crucial.Challenges with Retrofits: Converting existing buildings to zero-emission standards is more challenging than new builds due to technical and financial complexities. Organizations like the Canada Green Building Council support retrofitting initiatives to reduce emissions.Role of Public Perception and Culture: Encouraging a culture of sustainability within educational institutions can influence students and staff, fostering environmental awareness and commitment to carbon reduction.

Achievability and Practicality: Zero-emission buildings are achievable, especially in new construction. While retrofitting presents challenges, organizations can meet energy and emission targets with the right resources and technology.Energy Metrics and Tracking: Tools like sub-metering allow zero-emission buildings to track energy use precisely, helping optimize and adjust operations to meet zero-carbon standards.Economic Viability: The Joyce Centre’s design and operation costs were comparable to conventional institutional buildings, showing that zero-emission buildings can be financially feasible without additional expenses.Public and Private Sector Opportunities: Dr. Cupido emphasizes that both sectors can adopt zero-emission practices. Government policies and financial incentives could further support such transitions.Student and Community Engagement: Sustainable buildings serve as educational platforms, instilling environmental responsibility in students and inspiring future professionals to prioritize green building solutions.
