Search: Decarbonizing the Built Environment: Rethinking Zero Net Energy

Course Description: 

We all know that carbon is the key to life…but within our built environment that same carbon is threatening that same life. This presentation will first discuss the concept of decarbonization within the building sector. What are the roles and impacts of both embodied and operational carbon? Is carbon the only concern? We will then shift the discussion to the process of applying decarbonization to our designs. How is our typical performance-based approach altered when we use GHG emissions as our primary metric? How does this new metric alter the construction practices and operational routines? Finally, we will discuss how decarbonization aligns with well-known performance standards such as Zero Net Energy & Living Building Challenge. Throughout the presentation, we will share our successes, challenges, and lessons learned from the perspective of the owner, builder, and designer, while targeting the next generation of sustainability goals.

Seminar Highlights:

1. What is decarbonization?

2. Why is decarbonization important?

3. What is the relative value of embodied carbon vs. operational carbon?

4. How does Electrification relate to decarbonization?

5. What different design decisions might be incorporated if the goal is Zero Carbon rather than Zero Net Energy?

6. How can you reduce embodied carbon?
