What you study	Architecture Environmental Studies General or Integrated Engineering	Astronomy Chemistry Environmental Studies Geology	Chemistry Environmental Studies Human Geography Physical Geography
What it is	You study how to repair, restore, and upgrade old buildings while making them environmentally sustainable. This program combines architecture, engineering, and environmental science — it's more specialized than a general architecture or engineering degree because it focuses specifically on conserving heritage structures and reducing their environmental impact. It suits people who care about preserving historic buildings and solving practical problems with green technology.	You study physical sciences — chemistry, physics, geology, and environmental topics — with a focus on how they connect to human health and the living world. This stream emphasizes the intersection between earth and life sciences rather than pure physics or chemistry alone. The co-op option lets you do paid work terms at relevant employers alongside your degree. It suits students interested in environmental health, toxicology, or science careers that bridge the natural world and wellness.	You study how Earth's climate and environment work, using chemistry, physics, and geography to understand weather systems, ecosystems, and human impacts. This program combines natural science with social geography, so you examine both the physical causes of environmental change and how people and communities respond to it. It suits students curious about climate science who want hands-on experience through co-op placements alongside their coursework.
