A Climate Analysis and Optimal Building Design for Edmonton

For our final environmental systems project, we designed and analyzed a one-storey open-plan building located in Edmonton, Alberta, with a focus on optimizing daylighting and energy performance. The 10m x 18m structure was modeled at 1:50 scale to study how solar orientation, window placement, and shading devices affect interior light quality and thermal comfort.

In Model 1, we explored different window configurations and shading strategies using sun path diagrams and ray tracing. We added overhangs, vertical louvers, and vegetation to manage glare and solar gain, and documented how these elements affected sunlight penetration on key seasonal dates. Model 2 incorporated our findings, redistributing glazing to improve daylighting and reduce heat loss, particularly on the south and west façades.

We developed an Excel-based energy model to calculate heat loss and gain through the building envelope, including conduction, ventilation, and solar gain. Our analysis showed that passive design strategies—such as optimized glazing, shading, and increased ventilation—can significantly reduce mechanical heating and cooling loads.

This project demonstrates how climate-responsive design in a northern city like Edmonton can enhance energy efficiency and occupant comfort through thoughtful integration of solar and thermal strategies.
