Design Principles
"Form follows performance: Architectural form should be iteratively refined based on quantitative performance analysis to achieve desired environmental and user-centric outcomes."
This research provides a data-driven approach for designers to proactively address crucial performance metrics during the conceptualization phase. By understanding the interplay of geometric factors, designers can create more sustainable and comfortable learning environments, reducing operational costs and improving user well-being.
What This Means for Your Design
When designing buildings with a central open space (atrium), especially for schools in cold places, changing the shape and direction of the building, how wide or narrow the atrium is, and how much of the roof is glass can make a big difference in how much natural light you get, how much energy is used for heating and cooling, and how comfortable people feel inside. Making smart choices about these shapes can save energy and make the space nicer.
