40-second trailer for a 22-minute documentary on energy-efficient buildings.

"Passive Passion" looks at the Passive House standard for buildings - a design method from Germany that results in 90% reductions in the energy needed for heating and cooling. Building to the standard is commonplace in many parts of Europe, but has been slow to catch on in the U.S., though a burgeoning community of American Passive House enthusiasts seek to spread the idea and change the fundamentals of how we build.
