My part of the joint session on Passive House—what it is and why it matters—with Stephan Tanner at the 2009 Minnesota AIA Convention.

The slideshow contains a lot of full-screen images but no subtitles, therefore omitting some of the information which would have been given verbally during the presentation.

  5. 5. “PASSIVHAUS” CERTIFIED PASSIVE HOUSE ™ TM A rigorous, voluntary building energy standard focusing on highest energy efficiency and quality of life at low operating cost. The Passive House Standard is the most rigorous building energy standard in the world. Consultants, projects or building components that have obtained the right to carry the logo have committed themselves to design excellence and the Passive House energy performance criteria.
  6. 6. global standard • Passive House Standard performance requirements are always the same, regardless of building location • Climate zone and a building’s distinctive location impact the design significantly • Therefore, Passive Houses will look differently depending on where they are located • Think globally, build locally
