Parametric Energy Modelling – Empowering Design Decisions

The building construction and operation sector accounts for a significant amount of global energy-related carbon emissions which amount to nearly 40% of annual global GHG emissions. Therefore, predicting buildings’ energy consumption and carbon emission in advance and implementing the most cost and energy-effective strategies accordingly to cut these emissions can help to combat climate change. Research has shown that using computational modelling and energy simulation is an effective approach to achieve this is by completing energy modelling from early in the design stage and use it as a tool to validate and explore design decisions. In this webinar, we will explore a workflow for leveraging parametric design tools to complete energy modelling starting in the early conceptual design stages. We will also discuss how this can be integrated into a broader program for firm-wide sustainability reporting to track progress against established targets, and explore challenges and opportunities to continue the energy analysis into the operational stage.



Learning Outcomes

  • Understand the foundations and relevant standards for energy modelling in Ontario.
  • Understand the structure and intent of ASHRAE Standard 209-2018.
  • Describe the benefits of completing energy modelling from early in the design stage.
  • Describe how energy modelling can be integrated into a firms sustainability reporting processes.
