What This Means for Your Design

Buildings designed to be 'passive' use smart construction and materials to stay warm in winter and cool in summer without needing much electricity for heating or air conditioning, saving energy and money over time.

How to use in your project

  • 1.Use findings on energy reduction percentages to justify design choices in your project.
  • 2.Cite the economic benefits of passive design to support the long-term viability of your proposed solution.
